Protein kinase, membrane-associated tyrosine/threonine 1 (PKMYT1)
A key hallmark of cancer is that cancer cells override the cell cycle controls that prevent commitment to division until the appropriate conditions have been fulfilled. Once the conditions are right, cells are pushed through a decision point called the “restriction point” into the cell division cycle by the activity of Cdk4/6-Cyclin D complexes. Once through this point of no return, cells activate Cdk2-Cyclin E in order to drive the duplication of the DNA that will be segregated into two daughter cells later in the cell cycle (by Cdk1-Cyclin B). In order to be able to proliferate illegitimately, cancer cells inappropriately boost the kinase activity of Cdk4/6-Cyclin D complexes or bypass the requirement for Cdk4/6-Cyclin D activation, by activating the downstream Cdk2-Cyclin E complex, independently of any input from Cdk4/6-Cyclin D. Implementation of either of these two approaches enable cancers to evade the normal controls that maintain balanced growth and homeostasis within the body. Consequently, cancer proliferation is unregulated. Drugs that inhibit the Cdk4/6-Cyclin D complexes are having a major therapeutic impact in hormone responsive HER2 negative breast cancer (HER2- ER+) and are being trialled in a variety of other cancers. In contrast, counteracting Cdk2-Cyclin E hyperactivation was considered to be undruggable until a recent study reported that a WEE1 family kinase called PKMYT1 is only essential when Cyclin E levels are abnormally high (Gallo et al., 2022). Importantly, they found that PKMYT1 ablation does not kill normal cells. The same study showed that PKMYT1 ablation is synthetically lethal in the presence of Cyclin E (CCNE1) over-expression; CCNE1 overexpression drives the transcription of Cyclin B to elevate Cyclin B levels to generate so much Cdk1-Cyclin B that all the available Cdk1 inhibitory activity is required to restrain this Cdk1-CyclinB and prevent a catastrophic mitosis. Thus, CCNE1 overproduction generates a dependency on PKMYT1. FBXW7 is a gene which encodes an E3 ligase that degrades Cyclin E. FBXW7 loss, has also been found to be synthetically lethal in the presence of PKMYT1 inhibition (Durocher et al., 2021), demonstrating that PKMYT1 drugs hold potential as first line therapy in several cancers. CCNE1 amplification has been reported in several cancer types including endometrial, ovarian, breast and gastric, ranging in frequency from 5-40%. CCNE1 amplification and/or FBXW7 mutations occur in >60% of uterine carcinosarcomas, >20% of uterine cancers, ~20% of ovarian cancers, ~18% of stomach cancers, ~14% of colorectal cancer, ~12% of bladder cancers, 11.5% of oesophageal cancers, ~11% of cervical cancers, 7.5% of sarcomas and ~7% of lung squamous cancers (Durocher et al., 2021). CCNE1 also occurs at lower levels in other cancers such as adenoid cystic carcinoma, pancreatic cancer, mesothelioma, lung adenocarcinoma, head & neck cancers, difuse large B-cells lymphoma, liver cancers and others (Gorski et al., 2020). Moreover, CCNE1 over expressing ovarian cancers are a subset of the 50% that are recombination proficient so do not benefit from PARP inhibitors (Gorski et al., 2020), highlighting the unmet need in these indications. CCNE1 amplification is observed in the more aggressive subtypes including uterine carcinosarcoma (UCS; ~40%), uterine serous carcinoma (USC; ~ 25%), high-grade serous ovarian carcinoma (HGSOC; ~20%), and triple-negative breast cancer (TNBC; ~8%). CCNE1 over- expression in tumor biopsies is linked to lower overall survival compared to patients with normal Cyclin E1 levels. HGSOC patients with CCNE1 over-expression have a lower response rate to cisplatin, the current standard of care. Similarly, FBXW7 is frequently mutated in several cancer types including uterine carcinosarcoma, endometrial, colorectal, cervical, bladder, head & neck, gastric, cancers and lung squamous cells carcinoma ranging in frequency from 5-39%. Like CCNE1 overexpression, FBXW7 driver mutations are observed in the more aggressive subtypes of endometrial cancer including UCS and USC. Elevation of Cdk2-Cyclin E activity, via a variety of means, is also associated with resistance to Cdk4/6 inhibitors (Fassl et al., 2022); this suggests that PKMYT1 inhibition will also constitute a robust second line treatment in the cohort of HER2- ER+ breast cancer patients treated with Cdk4/6 inhibitors who generally develop resistance after around 2 years of therapy. A recently discovered inhibitor of PKMYT1, RP-6306 (Szychowski et al., 2022), has shown efficacy in vivo in models of breast and ovarian cancers overexpressing CCNE1, as well as in a pancreatic PDX model with increased expression of CCNE1, alone or in combination with Gemcitabine (Gallo et al., 2022). It has been claimed that synthetic lethality occurs in cancer cells between PKMYT1 inhibition and deficiency in protein phosphatase 2 (PP2A), in particular, regulatory subunit B alpha (PPP2R2A) (Yost et al., 2021). PPP2R2A inactivation is present in 15% of prostate adenocarcinoma, and at >5% in Ovarian serous cystadenocarcinoma, rectum adenocarcinoma, Bladder Urothelial Carcinoma, colorectal adenocarcinoma, breast invasive carcinoma, Uterine Corpus Endometrial Carcinoma, Uterine Carcinosarcoma, Liver hepatocellular carcinoma, Lung squamous cell carcinoma, lung adenocarcinoma. PKMYT1 is a cell cycle regulating kinase, part of the WEE1 family of kinases that includes WEE1 and WEE2. WEE2 is restricted to gonads as it regulates meiosis. In contrast both PKMYT1 and WEE1 are ubiquitously expressed. PKMYT1 is localized predominantly in the endoplasmic reticulum and Golgi complex, while WEE1 is predominantly a nuclear protein. PKMYT1 is involved in the negative regulation of the CDK1-Cyclin B complex which promotes the progression of cells from G2-phase into the mitotic phase (M-phase) of the cell cycle. The biology of Cyclin E overproduction generates a need for the otherwise non-essential PKMYT1. Cyclin E accumulation boosts the transcription of cyclin B1; the potential to form active Cdk1-Cyclin B is greatly enhanced by CCNE1 overexpression. This places a far greater demand upon the Cdk1-Cyclin B inhibitory activity of WEE1 and PKMYT1 such that PKMYT1 becomes essential. Furthermore, CCNE1 overproduction stimulates abnormally high levels of DNA replication that deplete the nucleotide pool and generate DNA damage (Jones et al, 2013). The DNA damage generated by Cyclin E accumulation is not in itself lethal because cells have G2/M checkpoints that restrain commitment to genome segregation in mitosis until all damage is repaired. These checkpoint pathways boost the activity of the Wee1 family kinases WEE1 and PKMYT1, which restrain division by phosphorylating Cdk1 kinase to block Cdk1-Cyclin B activity. While damage persists, WEE1 and PKMYT1 activities remain high and cells cannot divide. Thus, WEE1 or PKMYT1 inhibition kills damaged cells by forcing them to divide when their DNA is still damaged and/or un-replicated. This places higher demands upon the ability of WEE1 and PKMYT1 to restrain CDK1-Cyclin B activity to maintain cell viability. PKMYT1 can be removed from untransformed cells because the requirement for restraint of CDK1-CyclinB1 activity can be met by WEE1 alone. It is only when abnormally high levels of DNA damage generates a greater need for CDK1 cyclin B inhibition that PKMYT1’s activities become essential. The WEE1 inhibitor adavosertib has progressed to clinical trials in a number of solid tumours (clinicaltrials.gov) but presented significant toxicity. WEE1 inhibition toxicity most likely arises from its ability to inhibit both CDK2 and CDK1 complexes. CDK2-Cyclin E and CDK2-Cyclin A regulate the initiation and progression through DNA replication. Release of excessive levels of CDK2-Cyclin activities will generate DNA damage in a phenomenon known as oncogene induced replicative senescence. PKMYT1 inhibition is unlikely to display similar S phase toxicity, because, unlike WEE1, it phosphorylates CDK1 (Booher et al., 1997; Liu et al., 1997). Collectively, the dependency on PKMYT1 that is generated by excessive Cdk2-Cyclin E activity in cancer cells and the markedly reduced toxicity in normal tissues arising from its restriction to CDK1 regulation make PKMYT1 is a highly attractive target for inhibition for patients whose tumours proliferate inappropriately because of enhanced Cdk2-Cyclin E activity. Overexpression of PKMYT1 has been observed in various cancers (compared to normal tissues), including Lung squamous cell carcinoma, lung adenocarcinoma, Uterine Corpus Endometrial Carcinoma, breast invasive carcinoma, hepatocellular carcinoma, clear-cell renal-cell carcinoma, Kidney Chromophobe cancer, renal papillary cell carcinoma, Head and Neck squamous cell carcinoma, colon adenocarcinoma, stomach adenocarcinoma, thyroid carcinoma, prostate adenocarcinoma. Elevated expression of PKMYT1 is associated with poor prognosis in adrenocortical carcinoma, kidney chromophobe, kidney renal clear cell carcinoma, kidney renal papillary cell carcinoma, lower grade glioma, liver hepatocellular carcinoma, lung adenocarcinoma, mesothelioma, pancreatic adenocarcinoma, prostate adenocarcinoma, skin cutaneous melanoma, uveal melanoma (Shao et al., 2021), and breast cancer (Liu et al., 2020). PKMYT1 is involved in the progression, invasion and/or metastasis of many solid tumours, for example non-small cell lung cancer (Zhang et al., 2022; He et al., 2021; Sun et al., 2019), osteosarcoma (Luo et al., 2022), clear cell renal cell carcinoma (Chen et al., 2020; Chen et al., 2021), oral squamous cell carcinoma (Cai et al., 2022), gastric cancer (Hu et al., 2022; Zhang et al., 2020), prostate cancer (Wang et al., 2020), oesophageal squamous cell carcinoma (Zhang et al., 2019), colorectal cancer (Jeong et al., 2018), hepatocellular carcinoma (Liu et al., 2017), ovarian cancer (Xuan et al., 2020), neuroblastoma (in particular with MYCN amplification) (Chayka et al., 2015), glioblastoma (Toledo et al., 2015). PKMYT1 is essential for survival of some haematologic malignancies, such as acute lymphoblastic leukemia and multiple myeloma (Ghelli Luserna di Rora et al., 2020). PKMYT1 can have application in addressing resistance to treatment or improving the efficacy of cancer treatment agents. PKMYT1 elevation has been reported as a resistance mechanism to sustained WEE1 inhibition (Lewis et al., 2019). PKMYT1 inhibitors may also be a useful second line treatment to complement the emerging WEE1i based therapies. Knockdown of PKMYT1 can eliminate the radiation-induced G2/M arrest, resulting in a lower survival rate for cells receiving radiation therapy and is therefore a promising target to improve the radiosensitivity of lung adenocarcinoma (Long et al., 2020). PKMYT1 could be also prove useful to enhance the efficacy of anti-microtubule cancer drugs (Visconti et al., 2017). PKMYT1 also plays a role in viral infection. Knockdown of PKMYT1 reduces the number of cells supporting Kaposi sarcoma herpesvirus (KSHV) lytic infection in S phase of the cell cycle (Bryan et al., 2006). KSHV is the cause of Kaposi’s sarcoma, primary effusion lymphoma (PEL) and the plasmablastic variant of multicentric Castleman’s disease. There is a clear need for PKMYT1 selective inhibitors with good pharmacokinetic properties, which are suitable for oral dosing with minimal or no toxicity. This disclosure provides compounds and compositions that selectively inhibit PKMYT1 to treat cancer.

The index “Cx-y” in terms such as “C9-10heteroaryl”, “C3-7heterocyclyl”, and the like, refers to the number of ring atoms, which may be carbon atoms or heteroatoms (e.g., N, O, S, as the case may be). For example, pyridyl is an example of a C6heteroaryl group, and piperidino is an example of a C6heterocyclyl group. The term “heteroaryl” refers to a group that is attached to the rest of the molecule by an atom that is part of an aromatic ring, wherein the aromatic ring is part of an aromatic ring system, and the aromatic ring system has one or more heteroatoms (e.g., N, O, S, as the case may be). Unless otherwise stated, the heteroaryl may be attached via a ring carbon or a ring nitrogen atom. For example, pyridyl is an example of a C6heteroaryl group, and quinolyl (e.g., quinolin-2-yl, quinolin-7-yl, etc.) is an example of a C10heteroaryl group. Furthermore, the aromatic ring system may optionally be fused with one or more non-aromatic rings which may contain one or more heteroatoms (e.g., N, O, S, as the case may be) or only carbon atoms. For example: 4,5,6,7- tetrahydro-1H-indol-2-yl is an example of a C9heteroaryl group; 4,5,6,7-tetrahydro-1H-pyrrolo[2,3- b]pyridin-2-yl is an example of a C9heteroaryl group. Pyridyl and furan are examples of C5-6heteroaryl. The term “heterocyclyl” refers to a group that contains at least one non aromatic ring system comprising one or more heteroatoms (e.g., N, O, S, as the case may be) that is attached to the rest of the molecule by an atom that is part of a non aromatic ring system comprising one or more heteroatoms (e.g., N, O, S, as the case may be). Unless otherwise stated, the heterocyclyl may be attached via a ring carbon or a ring nitrogen atom. In one embodiment, the term “heterocyclyl” refers to a group that is attached to the rest of the molecule by an atom that is part of a non-aromatic ring, wherein the non-aromatic ring is part of a non-aromatic ring system, and the non-aromatic ring system has one or more heteroatoms (e.g., N, O, S, as the case may be). Unless otherwise specified, a sulfur ring atom may be substituted with one or two oxo (=O) groups (for example, as in 1,1-dioxo-1,4-thiazinany-4-yl). Unless otherwise specified, “heterocyclyl” includes monocyclic heterocyclyl (e.g., piperidinyl, an example of a monocyclic C6heterocyclyl), fused heterocyclyl (e.g., 3-azabicyclo[3.1.0]hexyl, an example of a fused C6heterocyclyl; decahydroquinolinyl, an example of a fused C10heterocyclyl), bridged heterocyclyl (e.g., 6-azabicyclo[3.1.1]heptanyl and 2,5-diazabicyclo[2.2.1]heptane, examples of a bridged C7heterocyclyl; 3,8-diazabicyclo[3.2.1]octanyl, an example of a bridged C8heterocyclyl), and spiro heterocyclyl (2,6-diazaspiro[3.3]heptane, an example of a spiro C7heterocyclyl; 7- azaspiro[3.5]nonyl, an example of a spiro C9heterocyclyl; 2,8-diazaspiro[4.5]decane, an example of a spiro C10heterocyclyl).Tetrahydropyran and pyrrolidine are examples of C3-7heterocyclyl. Furthermore, the non-aromatic ring system may optionally be fused with one or more aromatic rings which may contain one or more heteroatoms (e.g., N, O, S, as the case may be) or only carbon atoms. For example: 4,5,6,7-tetrahydro-1H-pyrrolo[2,3-b]pyridin-5-yl is an example of a C9heterocyclyl group; 1,2,3,4-tetrahydroisoquinolin-3-yl is an example of a C10heterocyclyl group. 2,3-Dihydro-1-benzofuran is an example of a C9heterocyclyl group where a non-aromatic ring system is fused with an aromatic ring.3,4-Dihydro-2H-1,4-benzoxazine and 2,3-dihydro-1,4- benzodioxine are examples of a C10heterocyclyl group where a non-aromatic ring system is fused with an aromatic ring. Examples of a “non-aromatic C3-7heterocyclyl” include oxetanyl, piperidine, pyrrolidine, tetrahydrofuran, tetrahydropyran, pyrrolidine, morpholinyl, azetidine and tetrahydrothiophene. A ”non-aromatic C3-11heterocyclyl having at least one N ring atom, and is attached via that N ring atom” contains at least one non aromatic ring system comprising at least one N ring atom that is attached to the rest of the molecule by that ring N atom, and may optionally contain one or more additional heteroatoms (e.g., N, O, S, as the case may be). Furthermore, the non-aromatic ring system may optionally be fused with one or more aromatic rings which may contain one or more heteroatoms (e.g., N, O, S, as the case may be) or only carbon atoms. In one embodiment the term “non-aromatic C3-11heterocyclyl having at least one N ring atom, and is attached via that N ring atom” refers to a heterocyclyl group that is attached via a N ring atom, but which may have additional N ring atoms. Examples include: aziridino, azetidino, pyrrolidino, piperidino, piperazino, morpholino, thiomorpholino, azepano, and diazepano. The term “carbocyclyl” refers to a ring system that contains at least one non aromatic carbon ring, and contains only carbon atoms. Unless otherwise specified, “carbocyclyl” includes monocyclic carbocyclyl (eg cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl), bicyclic carbocyclyl (eg 2,3-dihydro-1H-indene), fused carbocyclyl (eg 7,8,9,11,12,13,14,15,16,17-decahydro-6H- cyclopenta[a]phenanthrene, core scaffold of estradiol), bridged carbocyclyl (eg 1,2,3,4-tetrahydro- 1,4-methanonaphthalene), and spiro carbocyclyl (eg 3',4'-dihydro-2'H-spiro[cyclopentane-1,1'- naphthalene]). The term “haloalkyl” refers to an alkyl group substituted with one or more halo groups (e.g., -F, -Cl, -Br, -I). The term “fluoroalkyl” refers to an alkyl group substituted with one or more -F groups. For example, -CF3 and -CHF2 are examples of a C1fluoroalkyl group; -CH2CF3 and -CH2CHF2 are examples of a C2fluoroalkyl group. The term “C1-4alkylene” refers to an alkyl group with two points of attachment. For example, -CH2- is an example of a C1alkylene group; -CH2CH2- and -CH(CH3)- are examples of a C2alkylene group; -CH2CH2CH2- and -CH(CH3)2- are examples of a C3alkylene group. Examples of C1-7alkyl, C1-6alkyl and C1-4alkyl include methyl, ethyl, propyl, isopropyl and butyl. Examples of C3-6cycloalkyl include cyclopropyl and cyclohexyl. Examples of C3-6cycloalkyl-C1-3alkyl include cyclopropylmethyl and cyclohexylethyl. Examples of phenyl-C1-3alkyl include benzyl and 2-phenylpropyl. Examples of C5-6heteroaryl-C1-3alkyl include pyrimidin-2- ylmethyl and thiazol-4-ylethyl. Examples of C2-6alkenyl include ethenyl and propenyl. The phrase “one or more groups” in the context of optional substituents (e.g., “one or more groups -RAR1C”, etc.) is necessarily constrained by the parent moiety and the number of positions on it that are suitable for substitution. In some parent moieties (e.g., tetrazolyl) there is only one position available for substitution. However, for other parent moieties, there may be several (e.g., phenyl has five). Except when constrained by the parent moiety, the “one or more groups” may be, e.g., 1, 2, 3, 4, etc., though more preferably is 1, 2, or 3, yet more preferably 1 or 2, still more preferably 1.
The phrase “substituent on carbon” is intended to refer to a substituent which is attached to a carbon ring atom. Similarly, the phrase “substituent on secondary nitrogen” is intended to refer to a substituent which is attached to a nitrogen ring atom which, in the absence of the substituent, would be a secondary nitrogen ring atom (i.e. , -NH-). Consequently, a pyridyl group may only have “substituents on carbon”, whereas 1 H-pyrrole may have both “substituents on carbon” and a “substituent on secondary nitrogen”, as illustrated below.
Similarly, a piperidine group may only have “substituents on carbon”, whereas piperizino may have both “substituents on carbon” and a “substituent on secondary nitrogen”, as illustrated below.
Certain groups despite having carbon ring atoms may not have any carbon ring atoms available for substitution. For example, a tetrazolyl group may only permit a “substituent on carbon” or may only permit a “substituent on secondary nitrogen”, as illustrated below.
Unless otherwise indicated, where a compound is shown or described which has one or more chiral centres, and two or more stereoisomers are possible, all such stereoisomers are disclosed and encompassed, both individually (e.g., as isolated from the other stereoisomer(s)) and as mixtures (e.g., as equimolar or non-equimolar mixtures of two or more stereoisomers). For example, unless otherwise indicated, where a compound has one chiral centre, each of the (R) and (S) enantiomers are disclosed and encompassed, both individually (e.g., as isolated from the other enantiomer) and as a mixture (e.g., as equimolar or non-equimolar mixtures of the two enantiomers). For example, the initial carbon atom of a pendant sec-butyl group, -CH(CH3)CH2CH3 is usually chiral, and so gives rise to stereoisomers, e.g., (R) and (S) enantiomers if it is the only chiral centre, each of which is disclosed and encompassed.

Combinations
It is appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention, which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable sub-combination. All combinations of the embodiments pertaining to the chemical groups represented by the variables (e.g., Ring A, Ring B, etc.) are specifically embraced by the present invention and are disclosed herein just as if each and every combination was individually and explicitly disclosed, to the extent that such combinations embrace compounds that are stable compounds (i.e., compounds that can be isolated, characterised, and tested for biological activity). In this context, the skilled person will readily appreciate that certain combinations of groups (e.g., substituents) may give rise to compounds which may not be readily synthesized and/or are chemically unstable. In addition, all sub-combinations of the chemical groups listed in the embodiments describing such variables are also specifically embraced by the present invention and are disclosed herein just as if each and every such sub-combination of chemical groups was individually and explicitly disclosed herein. Substantially Purified Forms One aspect of the present invention pertains to BAA compounds, as described herein, in substantially purified form and/or in a form substantially free from contaminants. In one embodiment, the substantially purified form is at least 50% by weight, e.g., at least 60% by weight, e.g., at least 70% by weight, e.g., at least 80% by weight, e.g., at least 90% by weight, e.g., at least 95% by weight, e.g., at least 97% by weight, e.g., at least 98% by weight, e.g., at least 99% by weight. Unless otherwise specified, the substantially purified form refers to the compound in any stereoisomeric or enantiomeric form. For example, in one embodiment, the substantially purified form refers to a mixture of stereoisomers, i.e., purified with respect to other compounds. In one embodiment, the substantially purified form refers to one stereoisomer, e.g., optically pure stereoisomer. In one embodiment, the substantially purified form refers to a mixture of enantiomers. In one embodiment, the substantially purified form refers to an equimolar mixture of enantiomers (i.e., a racemic mixture, a racemate). In one embodiment, the substantially purified form refers to one enantiomer, e.g., optically pure enantiomer. In one embodiment, the contaminants represent no more than 50% by weight, e.g., no more than 40% by weight, e.g., no more than 30% by weight, e.g., no more than 20% by weight, e.g., no more than 10% by weight, e.g., no more than 5% by weight, e.g., no more than 3% by weight, e.g., no more than 2% by weight, e.g., no more than 1% by weight. Unless specified, the contaminants refer to other compounds, that is, other than stereoisomers or enantiomers. In one embodiment, the contaminants refer to other compounds and other stereoisomers. In one embodiment, the contaminants refer to other compounds and the other enantiomer. In one embodiment, the substantially purified form is at least 60% optically pure (i.e., 60% of the compound, on a molar basis, is the desired stereoisomer or enantiomer, and 40% is the undesired stereoisomer or enantiomer), e.g., at least 70% optically pure, e.g., at least 80% optically pure, e.g., at least 90% optically pure, e.g., at least 95% optically pure, e.g., at least 97% optically pure, e.g., at least 98% optically pure, e.g., at least 99% optically pure. Isomers Certain compounds may exist in one or more particular geometric, optical, enantiomeric, diastereoisomeric, epimeric, atropic, stereoisomeric, tautomeric, conformational, or anomeric forms, including but not limited to, cis- and trans-forms; E- and Z-forms; c-, t-, and r- forms; endo- and exo-forms; R-, S-, and meso-forms; D- and L-forms; d- and l-forms; (+) and (-) forms; keto-, enol-, and enolate-forms; syn- and anti-forms; synclinal- and anticlinal-forms; α- and β-forms; axial and equatorial forms; boat-, chair-, twist-, envelope-, and halfchair-forms; and combinations thereof, hereinafter collectively referred to as “isomers” (or “isomeric forms”). A reference to a class of structures may well include structurally isomeric forms falling within that class (e.g., C1-6alkyl includes n-propyl and iso-propyl; butyl includes n-, iso-, sec-, and tert-butyl; methoxyphenyl includes ortho-, meta-, and para-methoxyphenyl). However, reference to a specific group or substitution pattern is not intended to include other structural (or constitutional isomers) which differ with respect to the connections between atoms rather than by positions in space. For example, a reference to a methoxy group, -OCH3, is not to be construed as a reference to its structural isomer, a hydroxymethyl group, -CH2OH. Similarly, a reference specifically to ortho-chlorophenyl is not to be construed as a reference to its structural isomer, meta-chlorophenyl. The above exclusion does not pertain to tautomeric forms, for example, keto-, enol-, and enolate-forms, as in, for example, the following tautomeric pairs: keto/enol (illustrated below), imine/enamine, amide/imino alcohol, amidine/amidine, nitroso/oxime, thioketone/enethiol, N-nitroso/hydroxyazo, and nitro/aci-nitro. A reference herein to one tautomer is intended to encompass both tautomers. For example, 1H-pyridin-2-one-5-yl and 2-hydroxyl-pyridin-5-yl (shown below) are tautomers of one another. A reference herein to one is intended to encompass both. Note that specifically included in the term “isomer” are compounds with one or more isotopic substitutions. For example, H may be in any isotopic form, including 1H, 2H (D), and 3H (T); C may be in any isotopic form, including 12C, 13C, and 14C; O may be in any isotopic form, including 16O and 18O; and the like. Unless otherwise specified, a reference to a particular compound includes all such isomeric forms, including mixtures (e.g., racemic mixtures) thereof. Methods for the preparation (e.g., asymmetric synthesis) and separation (e.g., fractional crystallisation and chromatographic means) of such isomeric forms are either known in the art or are readily obtained by adapting the methods taught herein, or known methods, in a known manner. Unless otherwise specified, a reference to a particular compound includes all such isomeric forms, including mixtures (e.g., racemic mixtures) thereof. Methods for the preparation (e.g., asymmetric synthesis) and separation (e.g., fractional crystallisation and chromatographic means) of such isomeric forms are either known in the art or are readily obtained by adapting the methods taught herein, or known methods, in a known manner. Salts It may be convenient or desirable to prepare, purify, and/or handle a corresponding salt of the compound, for example, a pharmaceutically-acceptable salt. The term “salt” is used herein to refer to a solid complex comprising a first co-forming entity (e.g. a compound such as a BAA compound) and a second co-forming entity (e.g. a suitable Brønsted acid or base), where there is complete transfer of a proton from one entity to another. Examples of pharmaceutically acceptable salts are discussed in Berge et al., 1977, “Pharmaceutically Acceptable Salts,” J. Pharm. Sci., Vol. 66, pp.1-19. For example, if the compound is anionic, or has a functional group, which may be anionic (e.g., -COOH may be -COO-), then a salt may be formed with a suitable cation. Examples of suitable inorganic cations include, but are not limited to, alkali metal ions such as Na+ and K+, alkaline earth cations such as Ca2+ and Mg2+, and other cations such as Al3+ as well as the ammonium ion (i.e., NH4 +). Examples of suitable organic cations include, but are not limited to substituted ammonium ions (e.g., NH3R+, NH2R2 +, NHR3 +, NR4 +), for example, where each R is independently linear or branched saturated C1-18alkyl, C3-8cycloalkyl, C3-8cycloalkyl-C1-6alkyl, and phenyl-C1-6alkyl, wherein the phenyl group is optionally substituted. Examples of some suitable substituted ammonium ions are those derived from: ethylamine, diethylamine, dicyclohexylamine, triethylamine, butylamine, ethylenediamine, ethanolamine, diethanolamine, piperazine, benzylamine, phenylbenzylamine, choline, meglumine, and tromethamine, as well as amino acids, such as lysine and arginine. An example of a common quaternary ammonium ion is N(CH3)4+. If the compound is cationic, or has a functional group, which upon protonation may become cationic (e.g., -NH2 may become -NH3 +), then a salt may be formed with a suitable anion. For example, if a parent structure contains a cationic group (e.g., -NMe2 +), or has a functional group, which upon protonation may become cationic (e.g., -NH2 may become -NH3 +), then a salt may be formed with a suitable anion. In the case of a quaternary ammonium compound a counter-anion is generally always present in order to balance the positive charge. If, in addition to a cationic group (e.g., -NMe2 +, -NH3 +), the compound also contains a group capable of forming an anion (e.g., -COOH), then an inner salt (also referred to as a zwitterion) may be formed. Examples of suitable inorganic anions include, but are not limited to, those derived from the following inorganic acids: hydrochloric, hydrobromic, hydroiodic, sulfuric, sulfurous, nitric, nitrous, phosphoric, and phosphorous.

Again, if the compound also contains a group capable of forming an anion (e.g., -COOH), then an inner salt may be formed. Unless otherwise specified, a reference to a particular compound also includes salt forms thereof. In one embodiment, the BAA compound is provided in the form of a salt. In one embodiment, the BAA compound is provided in a neutral form (for example as a free acid, free base, or zwitterion). Solvates and Hydrates It may be convenient or desirable to prepare, purify, and/or handle a corresponding solvate of the compound. The term “solvate” is used herein in the conventional sense to refer to a complex of solute (e.g., compound, salt of compound) and solvent. If the solvent is water, the solvate may be conveniently referred to as a hydrate, for example, a mono-hydrate, a di-hydrate, a tri-hydrate, etc. Unless otherwise specified, a reference to a particular compound also includes solvate and hydrate forms thereof. In one embodiment, the BAA compound is provided in the form of a solvate. In one embodiment, the BAA compound is provided in the form of a hydrate. In one embodiment, the BAA compound is provided in unsolvated form. Chemically Protected Forms It may be convenient or desirable to prepare, purify, and/or handle the compound in a chemically protected form. The term “chemically protected form” is used herein in the conventional chemical sense and pertains to a compound in which one or more reactive functional groups are protected from undesirable chemical reactions under specified conditions (e.g., pH, temperature, radiation, solvent, reactive chemical reagents, and the like). In practice, well-known chemical methods are employed to reversibly render unreactive a functional group, which otherwise would be reactive, under specified conditions. In a chemically protected form, one or more reactive functional groups are in the form of a protected or protecting group (alternatively as a masked or masking group or a blocked or blocking group). By protecting a reactive functional group, reactions involving other unprotected reactive functional groups can be performed, without affecting the protected group; the protecting group may be removed or the masking group transformed, usually in a subsequent step, without substantially affecting the remainder of the molecule. See, for example, Protective Groups in Organic Synthesis (T. Green and P. Wuts; 4th Edition; John Wiley and Sons, 2006). A wide variety of such “protecting,” “blocking,” or “masking” methods are widely used and well known in organic synthesis. For example, a compound which has two non-equivalent reactive functional groups, both of which would be reactive under specified conditions, may be derivatized to render one of the functional groups “protected,” and therefore unreactive, under the specified conditions; so protected, the compound may be used as a reactant which has effectively only one reactive functional group. After the desired reaction (involving the other functional group) is complete, the protected group may be “deprotected” to return it to its original functionality. For example, a hydroxy group may be protected as an ether (-OR) or an ester (-OC(=O)R), for example, as: a t-butyl ether; a benzyl, benzhydryl (diphenylmethyl), or trityl (triphenylmethyl) ether; a trimethylsilyl or t-butyldimethylsilyl ether; or an acetyl ester (-OC(=O)CH3, -OAc). For example, an aldehyde or ketone group may be protected as an acetal (R-CH(OR)2) or ketal (R2C(OR)2), respectively, in which the carbonyl group (>C=O) is converted to a 1,1-diether (>C(OR)2), by reaction with, for example, a primary alcohol in the presence of an acid. The aldehyde or ketone group is readily regenerated, for example, by hydrolysis using water in the presence of acid. For example, an amine group may be protected, for example, as an amide (-NRCO-R), for example: as an acetamide (-NHCO-CH3); or as a carbamate (-NRCO-OR), for example: as a benzyloxy carbamate (-NHCO-OCH2C6H5, -NH-Cbz), as a t-butoxy carbamate (-NHCO-OC(CH3)3, -NH-Boc); as a 2-biphenyl-2-propoxy carbamate (-NHCO-OC(CH3)2C6H4C6H5, -NH-Bpoc), as a 9-fluorenylmethoxy carbamate (-NH-Fmoc), as a 6- nitroveratryloxy carbamate (-NH-Nvoc), as a 2-trimethylsilylethyloxy carbamate (-NH-Teoc), a 2,2,2-trichloroethyloxy carbamate (-NH-Troc), as an allyloxy amide (-NH-Alloc), or as a 2(- phenylsulfonyl)ethyloxy carbamate (-NH-Psec); or, in suitable cases (e.g., cyclic amines), as a nitroxide radical (>N-O●); or, in suitable cases (e.g., heterocyclic nitrogens), as a 2- trimethylsilylethoxymethyl (N-SEM). For example, a carboxylic acid group may be protected as an ester for example, as: an C1-7alkyl ester (e.g., a methyl ester; a t-butyl ester); a C1-7haloalkyl ester (e.g., a 2,2,2-trihaloethyl ester); a 2-tri( C1-7alkyl)silyl-ethyl ester; or a C5-20aryl-C1-7alkyl ester (e.g., a benzyl ester; a nitrobenzyl ester); or as an amide or hydrazide, for example, as acetamide or a N,N,N’-trimethylhydrazide. For example, a thiol group may be protected as a thioether (-SR), for example, as: a benzyl thioether; an acetamidomethyl ether (-S-CH2NHC(=O)CH3). Prodrugs It may be convenient or desirable to prepare, purify, and/or handle the compound in the form of a prodrug. The term “prodrug,” as used herein, pertains to a compound, which yields the desired active compound in vivo. Typically, the prodrug is inactive, or less active than the desired active compound, but may provide advantageous handling, administration, or metabolic properties. For example, some prodrugs are esters of the active compound (e.g., a physiologically acceptable metabolically labile ester). During metabolism, the ester group (-C(=O)OR) is cleaved to yield the active drug. Such esters may be formed by esterification, for example, of any of the carboxylic acid groups (-C(=O)OH) in the parent compound, with, where appropriate, prior protection of any other reactive groups present in the parent compound, followed by deprotection if required. Also, some prodrugs are activated enzymatically to yield the active compound, or a compound, which, upon further chemical reaction, yields the active compound (for example, as in antibody directed enzyme prodrug therapy (ADEPT), gene directed enzyme prodrug therapy (GDEPT), ligand-directed enzyme prodrug therapy (LIDEPT), etc.). For example, the prodrug may be a sugar derivative or other glycoside conjugate, or may be an amino acid ester derivative.

For example, suitable assays are described herein and/or are known in the art. One of ordinary skill in the art is readily able to determine whether or not a candidate compound inhibits PKMYT1 (e.g., inhibits or reduces or blocks or the activity or function of PKMYT1) in a cell. For example, a sample of cells may be grown in vitro and a compound brought into contact with said cells, and the effect of the compound on those cells observed.

Furthermore, the subject (e.g., patient) may be any of its forms of development, for example, a foetus. In one preferred embodiment, the subject (e.g., patient) is a human. Formulations While it is possible for a BAA compound to be administered alone, it is preferable to present it as a pharmaceutical formulation (e.g., composition, preparation, medicament) comprising at least one BAA compound, as described herein, together with one or more other pharmaceutically acceptable ingredients well known to those skilled in the art, including, for example, pharmaceutically acceptable carriers, diluents, excipients, adjuvants, fillers, buffers, preservatives, anti-oxidants, lubricants, stabilisers, solubilisers, surfactants (e.g., wetting agents), masking agents, colouring agents, flavouring agents, and sweetening agents. The formulation may further comprise other active agents, for example, other therapeutic or prophylactic agents. Thus, also described herein are pharmaceutical compositions, as defined above, and methods of making a pharmaceutical composition comprising mixing at least one BAA compound, as described herein, together with one or more other pharmaceutically acceptable ingredients well known to those skilled in the art, e.g., carriers, diluents, excipients, etc. If formulated as discrete units (e.g., tablets, etc.), each unit contains a predetermined amount (dosage) of the compound. The term “pharmaceutically acceptable,” as used herein, pertains to compounds, ingredients, materials, compositions, dosage forms, etc., which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of the subject in question (e.g., human) without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio. Each carrier, diluent, excipient, etc. must also be “acceptable” in the sense of being compatible with the other ingredients of the formulation. Suitable carriers, diluents, excipients, etc. can be found in standard pharmaceutical texts, for example, Remington: The Science and Practice of Pharmacy, 21st edition, Lippinott Williams and Wilkins, 2005; Remington: The Science and Practice of Pharmacy, 22nd edition, Pharmaceutical Press, 2012; and Handbook of Pharmaceutical Excipients, 7th edition, Pharmaceutical Press, 2012. The formulations may be prepared by any methods well known in the art of pharmacy. Such methods include the step of bringing into association the compound with a carrier which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association the compound with carriers (e.g., liquid carriers, finely divided solid carrier, etc.), and then shaping the product, if necessary. The formulation may be prepared to provide for rapid or slow release; immediate, delayed, timed, or sustained release; or a combination thereof. Formulations may suitably be in the form of liquids, solutions (e.g., aqueous, non-aqueous), suspensions (e.g., aqueous, non-aqueous), emulsions (e.g., oil-in-water, water-in-oil), elixirs, syrups, electuaries, mouthwashes, drops, tablets (including, e.g., coated tablets), granules, powders, losenges, pastilles, capsules (including, e.g., hard and soft gelatin capsules), cachets, pills, ampoules, boluses, suppositories, pessaries, tinctures, gels, pastes, ointments, creams, lotions, oils, foams, sprays, mists, or aerosols. Formulations may suitably be provided as a patch, adhesive plaster, bandage, dressing, or the like which is impregnated with one or more compounds and optionally one or more other pharmaceutically acceptable ingredients, including, for example, penetration, permeation, and absorption enhancers. Formulations may also suitably be provided in the form of a depot or reservoir. The compound may be dissolved in, suspended in, or mixed with one or more other pharmaceutically acceptable ingredients. The compound may be presented in a liposome or other microparticulate which is designed to target the compound, for example, to blood components or one or more organs. Formulations suitable for oral administration (e.g., by ingestion) include liquids, solutions (e.g., aqueous, non-aqueous), suspensions (e.g., aqueous, non-aqueous), emulsions (e.g., oil-in- water, water-in-oil), elixirs, syrups, electuaries, tablets, granules, powders, capsules, cachets, pills, ampoules, boluses. Formulations suitable for buccal administration include mouthwashes, losenges, pastilles, as well as patches, adhesive plasters, depots, and reservoirs. Losenges typically comprise the compound in a flavoured basis, usually sucrose and acacia or tragacanth. Pastilles typically comprise the compound in an inert matrix, such as gelatin and glycerin, or sucrose and acacia. Mouthwashes typically comprise the compound in a suitable liquid carrier. Formulations suitable for sublingual administration include tablets, losenges, pastilles, capsules, and pills. Formulations suitable for oral transmucosal administration include liquids, solutions (e.g., aqueous, non-aqueous), suspensions (e.g., aqueous, non-aqueous), emulsions (e.g., oil-in-water, water-in-oil), mouthwashes, losenges, pastilles, as well as patches, adhesive plasters, depots, and reservoirs. Formulations suitable for non-oral transmucosal administration include liquids, solutions (e.g., aqueous, non-aqueous), suspensions (e.g., aqueous, non-aqueous), emulsions (e.g., oil-in- water, water-in-oil), suppositories, pessaries, gels, pastes, ointments, creams, lotions, oils, as well as patches, adhesive plasters, depots, and reservoirs. Formulations suitable for transdermal administration include gels, pastes, ointments, creams, lotions, and oils, as well as patches, adhesive plasters, bandages, dressings, depots, and reservoirs. Tablets may be made by conventional means, e.g., compression or moulding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine the compound in a free-flowing form such as a powder or granules, optionally mixed with one or more binders (e.g., povidone, gelatin, acacia, sorbitol, tragacanth, hydroxypropylmethyl cellulose); fillers or diluents (e.g., lactose, microcrystalline cellulose, calcium hydrogen phosphate); lubricants (e.g., magnesium stearate, talc, silica); disintegrants (e.g., sodium starch glycolate, cross-linked povidone, cross-linked sodium carboxymethyl cellulose); surface- active or dispersing or wetting agents (e.g., sodium lauryl sulfate); preservatives (e.g., methyl p-hydroxybenzoate, propyl p-hydroxybenzoate, sorbic acid); flavours, flavour enhancing agents, and sweeteners. Moulded tablets may be made by moulding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent. The tablets may optionally be coated or scored and may be formulated so as to provide slow or controlled release of the compound therein using, for example, hydroxypropylmethyl cellulose in varying proportions to provide the desired release profile. Tablets may optionally be provided with a coating, for example, to affect release, for example an enteric coating, to provide release in parts of the gut other than the stomach. Ointments are typically prepared from the compound and a paraffinic or a water-miscible ointment base. Creams are typically prepared from the compound and an oil-in-water cream base. If desired, the aqueous phase of the cream base may include, for example, at least about 30% w/w of a polyhydric alcohol, i.e., an alcohol having two or more hydroxyl groups such as propylene glycol, butane-1,3-diol, mannitol, sorbitol, glycerol and polyethylene glycol and mixtures thereof. The topical formulations may desirably include a compound which enhances absorption or penetration of the compound through the skin or other affected areas. Examples of such dermal penetration enhancers include dimethylsulfoxide and related analogues. Emulsions are typically prepared from the compound and an oily phase, which may optionally comprise merely an emulsifier (otherwise known as an emulgent), or it may comprise a mixture of at least one emulsifier with a fat or an oil or with both a fat and an oil. Preferably, a hydrophilic emulsifier is included together with a lipophilic emulsifier which acts as a stabiliser. It is also preferred to include both an oil and a fat. Together, the emulsifier(s) with or without stabiliser(s) make up the so-called emulsifying wax, and the wax together with the oil and/or fat make up the so-called emulsifying ointment base which forms the oily dispersed phase of the cream formulations. Suitable emulgents and emulsion stabilisers include Tween 60, Span 80, cetostearyl alcohol, myristyl alcohol, glyceryl monostearate and sodium lauryl sulfate. The choice of suitable oils or fats for the formulation is based on achieving the desired cosmetic properties, since the solubility of the compound in most oils likely to be used in pharmaceutical emulsion formulations may be very low. Thus the cream should preferably be a non-greasy, non-staining and washable product with suitable consistency to avoid leakage from tubes or other containers. Straight or branched chain, mono- or dibasic alkyl esters such as di-isoadipate, isocetyl stearate, propylene glycol diester of coconut fatty acids, isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate, 2-ethylhexyl palmitate or a blend of branched chain esters known as Crodamol CAP may be used, the last three being preferred esters. These may be used alone or in combination depending on the properties required. Alternatively, high melting point lipids such as white soft paraffin and/or liquid paraffin or other mineral oils can be used. Formulations suitable for intranasal administration, where the carrier is a liquid, include, for example, nasal spray, nasal drops, or by aerosol administration by nebuliser, include aqueous or oily solutions of the compound. Formulations suitable for intranasal administration, where the carrier is a solid, include, for example, those presented as a coarse powder having a particle size, for example, in the range of about 20 to about 500 microns which is administered in the manner in which snuff is taken, i.e., by rapid inhalation through the nasal passage from a container of the powder held close up to the nose. Formulations suitable for pulmonary administration (e.g., by inhalation or insufflation therapy) include those presented as an aerosol spray from a pressurised pack, with the use of a suitable propellant, such as dichlorodifluoromethane, trichlorofluoromethane, dichorotetrafluoroethane, carbon dioxide, or other suitable gases. Formulations suitable for ocular administration include eye drops wherein the compound is dissolved or suspended in a suitable carrier, especially an aqueous solvent for the compound. Formulations suitable for rectal administration may be presented as a suppository with a suitable base comprising, for example, natural or hardened oils, waxes, fats, semi-liquid or liquid polyols, for example, cocoa butter or a salicylate; or as a solution or suspension for treatment by enema. Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams or spray formulations containing in addition to the compound, such carriers as are known in the art to be appropriate. Formulations suitable for parenteral administration (e.g., by injection), include aqueous or non-aqueous, isotonic, pyrogen-free, sterile liquids (e.g., solutions, suspensions), in which the compound is dissolved, suspended, or otherwise provided (e.g., in a liposome or other microparticulate). Such liquids may additionally contain other pharmaceutically acceptable ingredients, such as anti-oxidants, buffers, preservatives, stabilisers, bacteriostats, suspending agents, thickening agents, and solutes which render the formulation isotonic with the blood (or other relevant bodily fluid) of the intended recipient. Examples of excipients include, for example, water, alcohols, polyols, glycerol, vegetable oils, and the like. Examples of suitable isotonic carriers for use in such formulations include Sodium Chloride Injection, Ringer's Solution, or Lactated Ringer's Injection. Typically, the concentration of the compound in the liquid is from about 1 ng/mL to about 10 μg/mL, for example from about 10 ng/mL to about 1 μg/mL. The formulations may be presented in unit-dose or multi-dose sealed containers, for example, ampoules and vials, and may be stored in a freeze-dried (lyophilised) condition requiring only the addition of the sterile liquid carrier, for example water for injections, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules, and tablets. Dosage It will be appreciated by one of skill in the art that appropriate dosages of the BAA compounds, and compositions comprising the BAA compounds, can vary from subject to subject (e.g., from patient to patient). Determining the optimal dosage will generally involve balancing the level of therapeutic benefit against any risk or deleterious side effects. The selected dosage level will depend on a variety of factors including, for example: the activity of the particular BAA compound; the route of administration; the time of administration; the rate of excretion of the BAA compound; the duration of the treatment; other drugs, compounds, and/or materials used in combination; the severity of the disorder; and the species, sex, age, weight, condition, general health, and prior medical history of the subject (e.g., patient). The amount of BAA compound and route of administration will ultimately be at the discretion of the physician, veterinarian, or clinician, although generally the dosage will be selected to achieve local concentrations at the site of action which achieve the desired effect without causing substantial harmful or deleterious side-effects. Administration can be effected in one dose, continuously or intermittently (e.g., in divided doses at appropriate intervals) throughout the course of treatment. Methods of determining the most effective means and dosage of administration are well known to those of skill in the art and will vary with the formulation used for therapy, the purpose of the therapy, the target cell(s) being treated, and the subject being treated. Single or multiple administrations can be carried out with the dose level and pattern being selected by the treating physician, veterinarian, or clinician. In general, a suitable dose of the BAA compound is in the range of about 0.01 mg to about 5000 mg (more typically about 0.1 mg to about 1000 mg, e.g., about 0.1 mg to about 300 mg) per day. Where the compound is a salt, a solvate, an ester, an amide, a prodrug, or the like, the amount administered is calculated on the basis of the parent compound and so the actual weight to be used is increased proportionately.

Biological Methods and Data BIOLOGICAL EXAMPLE 1: PKMYT1 protein production Human PKMYT175-362 was cloned as a TEV cleavable 6xHis fusion in bacterial cells. After purification on a Ni++ HiTrap Chelating HP column, the His-tag was cleaved using TEV protease. Cleaved PKMYT1 was further purified on a Superdex 20016/600 sizing column. The fractions containing PKMYT1 were pooled and concentrated using an ultrafiltration centrifugal protein concentrator. The purified protein was aliquoted, flash frozen in liquid nitrogen, and stored at −80°C. BIOLOGICAL EXAMPLE 2: ADP-Glo enzymatic assays PKMYT1 biochemical assay: Inhibition of PKMYT1 was assessed using the ADP-GloTM Max Detection System from Promega. This assay detects the production of ADP from ATP by PKMYT1 via a two-step process ultimately involving the conversion of ADP to ATP with the latter converted to light in a coupled reaction with luciferase/luciferin. Inhibition of PKMYT1 by small molecule inhibitors results in a retardation of luminescence above background. The intrinsic ATPase activity of PKMYT1 was assessed according to the following protocol. Compounds were dosed into Corning white low volume 384 well assay plates using an Echo acoustic dispenser to generate 10- point curves spanning a 3-fold dilution series. DMSO (no inhibitor) control wells were prepared to benchmark the maximum and minimum signals in the presence and absence of PKMYT1, respectively. The PKMYT1 kinase domain was purified in-house, as described above, and added to the wells at a final concentration of 15 nM in a buffer of 50 mM HEPES (pH 7.5), 10 mM MgCl2, 1 mM EGTA, 0.01 % Brij-35, 1 % DMSO. 500 μM ATP was added to start the reaction with the final assay volume being 4 μl. The plate was then incubated for 60 minutes at 26oC before the addition of 4 μl of ADP-Glo Reagent to stop the reaction and deplete the unconsumed ATP. Following a further 60 minute incubation the assay signal was developed by the addition of 8 μl ADP-Glo Max Detection Reagent. After 60 minutes the luminescence signal was read on a PHERAStar FS microplate reader (BMG Labtech). Selectivity versus WEE1 assay: Selectivity was established using the same format as outlined for PKMYT1. After dosing of compounds via the Echo acoustic dispenser - as described above - WEE1 (Thermo Fisher PR7373A) was added to each well at a final concentration of 15 nM in a buffer of 50 mM HEPES (pH 7.5), 10 mM MgCl2, 1 mM EGTA, 0.01 % Brij-35, 1 % DMSO. 30 μM ATP was added to start the reaction with the final assay volume being 4 μl. The plate was then incubated for 60 minutes at 26 oC before the addition of 4 μl of ADP-Glo Reagent. Following a further 60 minute incubation the assay signal was developed by the addition of 8 μl ADP-Glo Detection Reagent. After 60 minutes the luminescence signal was read on a PHERAStar FS microplate reader (BMG Labtech). Data analysis: Data was captured and analysed within the Dotmatics Studies software module where dose response curves were generated and IC50 values determined. Acceptance and verification of data followed strict in-house business rules which are summarised as follows. All assay plates should demonstrate Z’ values >0.5 and reference compounds run on each plate should fall within 2-fold of the geometric mean of historical IC50 values. Technical and biological replicates of each compound are routinely tested and replicate IC50 values must fall within 3-fold of each other with dose response curves showing ‘goodness of fit’ r2 values >0.9. Failure to meet any of these defined criteria result in rejection of data. The data for the primary biochemical assay (PKMYT1 IC50) and selectivity assay (WEE1 IC50) are summarised in the following Biological Data Table 1. The PKMYT1 IC50 and WEE1 IC50 values are banded as follows: A: <50 nM; B: 50 nM - <1 μM; C: 1 μM - 11 μM; D: >11 μM. The PKMYT1 vs WEE1 selectivity is banded by fold difference in selectivity for PKMYT1 over WEE1 as follows: V: 3 - <10 fold; W: 10 - <100 fold; X: 100 - <1000 fold; Y: 1000 - 5000 fold; Z: >5000 fold. Where either the PKMYT1 IC50 value was below the lowest concentration limit of the assay or the WEE1 IC50 value was above the top concentration limit of the assay, the PKMYT1 vs WEE1 selectivity is given as “>N”, where N is the selectivity band. The selectivity value for these compounds falls at least in this band but could be higher. Biological Data Table 1

Biological Data Table 3 BIOLOGICAL EXAMPLE 5: Cancer Cell Lines Proliferation Assays – ATP-based cell viability endpoint Cancer cell lines with either normal (KYSE-30) or amplified CCNE1 expression (OVCAR 3 – ovarian cancer) were evaluated for their sensitivity to PKMYT1 inhibitors using Cell Titre Glow assay (Promega G7573) as endpoint to assess cell proliferation. The luminescence signal was read on a PHERAStar FS microplate reader (BMG Labtech). Data analysis was performed using Microsoft Excel® and GI50 (concentration that achieves 50% cell growth proliferation inhibition) estimates generated with GraphPad Prism v9. The following compounds in Biological Data Table 2 inhibit OVCAR 3 cell proliferation with a GI50 <0.5 μM. In addition, selected compounds exhibit >3-fold selectivity for the CCNE1-amplified OVCAR 3 cells compared to KYSE30 cells expressing normal levels of CCNE1.

The selectivity value for these compounds falls at least in this band but could be higher. Biological Data Table 4 BIOLOGICAL EXAMPLE 6: Inhibition of cellular PKMYT1 biomarker CDK1 pT14 To determine compound PKMYT1 IC50 in a cellular assay, OVCAR 3 cells were incubated at 37°C in 5% CO2 atmosphere. The cells were maintained in RPMI medium supplemented with 20% foetal bovine serum, 1X non essential amino acids, 1mM sodium pyruvate, Glutamax and insulin. Cells were seeded into 12-well plates at low density (50,000-200,000 cells per well), grown to confluence (~350-400,000 cells per well) and then treated with a range of concentrations of PKMYT1 inhibitors. The cells were incubated 20 hours and then harvested into 1X Laemmli Sample Buffer (BIORAD) without 2-mercaptoethanol, heated to 95°C for 5 min, centrifuged and sonicated using a microprobe for 15 sec, 21W to shear the DNA. The samples were analysed by immunoblot on a Jess Automated Western Blot System (BioTechne). The samples were separated using the 12-230 kDa Separation Module (BioTechne,) and blotted using an anti-CDK1 phospho T14 antibody (Abcam, #ab58509) and an anti-vinculin antibody (Abcam, #126002). Specific binding was detected by fluorescence using the Anti-Rabbit Detection Module (BioTechne, #DM-001), quantified using Compass for Simple Western software, and IC50 values were calculated by regression analysis in GraphPad Prism. The following compounds in Biological Data Table 5 inhibit CDK1 pT14 in OVCAR 3 cells with an IC50 <1 μM. The CDK1 pT14 IC50 values are banded as follows: A: <100 nM; B: 100 nM - 1 μM;
BIOLOGICAL EXAMPLE 7: Comparison Data 1 IC50 was measured for BAA-001, REF-001 and REF-002 as described for PKMYT1 biochemical ADP-Glo enzymatic assay in Biological Example 2. See Biological Data Table 4, below. As compared to REF-001, BAA-001 exhibits a 163-fold improvement in PKMYT1 IC50. As compared to REF-002, BAA-001 exhibits an 82-fold improvement in PKMYT1 IC50. The enhancement in activity seen when the phenol ring is substituted at both positions ortho to the amide group indicates that this ortho-disubstituted pattern confers surprising and unexpected improvements in PKMYT1 potency as compared to single substitution in either the 2- or 4-posiiton of the phenol ring. Biological Data Table 4 BIOLOGICAL EXAMPLE 8: Comparison Data 2 IC50 was measured for BAA-004, REF-003, and REF-004 as described for PKMYT1 biochemical ADP-Glo enzymatic assay in Biological Example 2. See Biological Data Table 5, below. As compared to REF-003, BAA-004 exhibits a 987-fold improvement in PKMYT1 IC50. As compared to REF-004, BAA-004 exhibits a >1800-fold improvement in PKMYT1 IC50. The enhancement seen when the di-ortho-substituted phenyl ring is hydroxyl substituted (i.e., a phenol) indicates that the hydroxyl substitution (meta to the amide group) confers surprising and unexpected improvements in PKMYT1 potency as compared to compounds lacking the hydroxyl substituent. Additionally, the data indicate that unsubstituted hydroxyl groups at this position lead to surprising and unexpected improvements as compared to substituted hydroxyl groups (e.g., alkyloxy).
