Abstract
Description
[Technical Field]
[0001] The present invention relates to compounds that are inhibitors of microtubule-associated serine / threonine-like kinase (MASTL), and the use of such compounds in the treatment of diseases and medical conditions mediated by MASTL, such as the treatment of cancer and other target-related diseases. [Background technology]
[0002] Microtubule-associated serine / threonine kinase homolog (MASTL), also known as Greatwall kinase (GWL), is a member of the AGC kinase family that regulates the mitotic phosphatase complex PP2A / B55. MASTL is located on human chromosome 10p12.1 and encodes an 850-amino acid protein. MASTL is unique among kinases because it contains an approximately 500-amino acid insertion between kinase subdomains VII and VIII, which correspond to the activation loop. The protein regulates mitotic entry and exit through its ability to inactivate the phosphatase PP2A / B55 (Castilho et al., 2009). The M phase kinase Greatwall (GWL) promotes inactivation of PP2A / B55delta, a phosphatase directed against CDK phosphosites (Mol. Biol. Cell. 20(22):4777-89). MASTL indirectly inhibits phosphatases through phosphorylation of ENSA and ARPP19 at S67 and S62 (pENSA / pARPP19), respectively (Gharbi-Ayachi et al., (2010). The substrate of Greatwall kinase, Arpp19, controls mitosis by inhibiting protein phosphatase 2A. (Science 330 1673-1677)). pENSA and pARPP19 are substrates of PP2A / B55, bind tightly to the complex, and inhibit the complex by undergoing dephosphorylation at an extremely slow rate, thereby suppressing the catalytic activity of PP2A / B55 through "unfair competition" (Williams et al., (2014). Greatwall-phosphorylated endosulfine is both an inhibitor and a substrate of PP2A-B55 heterotrimers. (eLife 3:e01695)).Cell entry into mitosis is regulated by a rapid increase in the phosphorylation of various substrates by CDK1 / CCNB1, which is accompanied by a decrease in the activity of PP2A / B55. MASTL is a substrate of CDK1 / CCNB1, and these activities combine to ensure that MASTL activity reaches its peak during mitosis. MASTL activity is essential for regulating mitotic exit by delaying the increase in PP2A / B55 activity until chromosome segregation is complete. Anaphase entry begins with APC / C-dependent ubiquitination of CCNB1, followed by its degradation by the proteasome. This attenuates CDK1 activity, ultimately inactivating MASTL and increasing the activity of PP2A / B55 phosphatases, which are necessary for timely exit from mitosis. Temporal regulation of PP2A / B55 reactivation by the PP2A-B55-ENSA / ARPP19-MASTL pathway is essential for orderly cytokinesis after chromosome segregation (Cundell et al., (2013). The BEG (PP2A-B55 / ENSA / Greatwall) pathway ensures cytokinesis follows chromosome separation. (Mol. Cell 52 393-405)). Suppression of MASTL kinase activity leads to premature cytokinesis, resulting in chromosome segregation defects and aneuploidy.
[0003] MASTL is known to be essential for cell cycle progression during embryogenesis in various organisms, including mice, frogs, and fruit flies. In mice, it remains essential for up to one year after birth, after which its loss (total deletion) is tolerated (Belen Sanz Castillo: Role of MASTL in mammals: Molecular functions and physiological relevance, 2017). Furthermore, an siRNA screen identified MASTL as a gene that can specifically suppress the proliferation of transformed (thyroid cancer) cells but not non-transformed cells (Anania et al., (2015) Identification of thyroid tumor cell vulnerabilities through a siRNA-based functional screening. (Oncotarget 6, 34629-34648)). These studies suggest that the nature of MASTL is not universal but is limited to early developmental steps in the embryo and organism. Furthermore, this study shows that some cancer cells revert to a state similar to the embryonic cell cycle state (where MASTL activity is essential), making their cell cycle regulatory mechanisms sensitive to MASTL loss. Ultimately, inhibitors of MASTL kinase have an excellent therapeutic scope, with broad applicability across a variety of cancers; therefore, MASTL is an ideal target for cancer therapy.
[0004] Many studies have demonstrated that MASTL plays an important role in cancer development. MASTL overexpression has been shown to be a potential prognostic indicator of breast (Alvarez-Fernandez et al. (2017)), oral cavity (Wang et al. (2014) Mastl kinase, a promising therapeutic target, promotes cancer recurrence. (Oncotarget 5 11479-11489)), and stomach (Sun et al. (2017) Mastl overexpression is associated with epithelial to mesenchymal transition and predicts a poor clinical outcome in gastric cancer. (Oncol. Lett. 14 7283-7287) Therapeutic relevance of the PP2A-B55 inhibitory kinase MASTL / Greatwall in breast cancer. (Cell Death Differ. 25, 828-840; Zhuge et al. (2017)). MASTL is a potential poor prognostic indicator in ER+ breast cancer. It has been identified in a variety of human tumors, including colon and rectal cancer (Eur. Rev. Med. Pharmacol. Sci. 21 2413-2420) and colorectal cancer (Vera et al., (2015)). Greatwall promotes cell transformation by hyperactivating AKT in human malignancies (eLife 4, e10115). Mouse xenograft studies using doxycycline-inducible knockout of MASTL by CRISPR / Cas9 in MDA-MB-231 cells showed a significant reduction in tumor size when MASTL was depleted compared to control animals. MASTL protein expression levels correlated with the aggressiveness of ER+ breast cancer and predicted poor patient survival (Alvarez-Fernandez et al., (2018)).Therapeutic relevance of the PP2A-B55 inhibitory kinase MASTL / Greatwall in breast cancer. (Cell Death Differ. 25 828-840)). Upregulation of MASTL is associated with cancer progression in head and neck tumors and is often associated with more aggressive forms of the disease. (Wang et al., (2014)). Mastl kinase, a promising therapeutic target, promotes cancer recurrence. (Oncotarget 5, 11479-11489)). Through a high-throughput siRNA screen in BCPAP thyroid cancer, vulnerability to MASTL loss was identified, which resulted in a significant decrease in cell proliferation. (Anania et al. (2015)). In colorectal cancer, upregulation of MASTL correlates with decreased patient survival and can act as a prognostic biomarker for potential disease aggressiveness (Uppada et al., (2018)). MASTL induces colon cancer progression and chemoresistance by promoting Wnt / β-catenin signaling. (Mol. Cancer 17:111). Supporting a therapeutic window, normal colonocytes do not express MASTL or express it only at very low levels. Depletion of MASTL in HCT-116 cells resulted in G2 / M arrest, apoptosis induction through modulation of anti-apoptotic proteins (Survivin and Bcl-xL, possibly through Gsk3β activation), and, importantly, in vivo. In vivo growth reduction was induced. Regulation of anti-apoptotic proteins by MASTL induction not only directly affected HCT-116 cell proliferation, but also increased their sensitivity to 5-FU treatment. MASTL is a novel inhibitor of acute myeloid leukemia (Tzelepis et al. (2016)).A CRISPR dropout screen identifies genetic vulnerabilities and therapeutic targets in acute myeloid leukemia (Cell Rep. 17, 1193-1205), and has illuminated potential new therapeutic targets for many cancers, such as head and neck squamous cell carcinoma (Wang et al., 2014), and thyroid cancer (Anania et al., 2015).
[0005] In addition to its role as a regulator of the G2 / M checkpoint, MASTL can deactivate checkpoint signaling and aid in recovery from DNA damage, supporting its role in the potential effects of DNA-damaging agents (Peng et al., (2010) "A novel role for greatwall kinase in recovery from DNA damage." (Cell Cycle 9 4364-4369)). An unbiased genome-wide siRNA loss-of-function screen in NSCLC cells identified MASTL as a key hit that sensitizes cells to radiation. This effect was not observed in primary human fibroblasts, indicating the possibility of selective sensitization of tumor cells over non-transformed cells (Nagel et al., (2015) "Genome-wide siRNA screen identifies the radiosensitizing effect of downregulation of MASTL and FOXM1 in NSCLC." (Mol. Cancer Ther. 14 1434-1444)). Similar effects were observed in a xenograft tumor model of UM-SSC-11-B cells derived from cisplatin-refractory head and neck squamous cell carcinoma (Wang et al., 2014). MASTL deficiency resensitized the cells to cisplatin treatment. Further parenchymal cell analysis studies in UM-SSC-11-B cells showed an increase in the sub-G1 population and induction of apoptosis, whereas MASTL-depleted normal oral keratinocyte OKF4 cells were resistant to apoptosis, regardless of cisplatin treatment.
[0006] Besides its role in cancer through regulation of damage repair pathways and mitosis, MASTL plays a role in regulating PP2A activity during interphase (Belen Sanz Castillo, 2017). Point mutations in the MASTL gene have been shown to cause autosomal dominant thrombocytopenia (Drachman et al., Autosomal dominant thrombocytopenia: incomplete megakaryocyte differentiation and linkage to human chromosome 10. (Blood. 2000;96:118-125.), providing evidence for a role for MASTL in megakaryocytic cells. More recently, it has been shown that such point mutations in MASTL do not induce decreased activity as originally thought, but rather exhibit a gain-of-function alteration that induces decreased PP2A activity accompanied by increased phosphorylation of Cdk and PP2A substrates (Hurtado et al., (2018) Thrombocytopenia-associated mutations in Ser / Thr kinase MASTL deregulate actin cytoskeletal dynamics in platelets. (J Clin Invest. 128(12):5351-5367). Therefore, MASTL inhibitors, through their effects on the PI3K / AKT pathway and cytoskeleton regulation, may hold therapeutic potential in the treatment of platelet disorders, including metabolic diseases (such as diabetes and obesity) and the rare genetic disease MASTL-associated thrombocytopenia, respectively.

[0021] definition As used in the specification and claims, the following terms have the following meanings unless otherwise specified.
[0022] The term "treat" or "treatment" refers to indications of successful treatment or amelioration of a disease, pathology, or condition, including palliative care; relief; reduction in symptoms or making the condition or state more tolerable to the patient; slowing the rate of degeneration or decline; making the end point of degeneration less debilitating; and objective or subjective parameters that improve the patient's physical or mental well-being. For example, certain methods herein treat cancer by reducing the symptoms of the cancer, which are known or can be determined by one of ordinary skill in the art. The term "treat" and its variants include prevention of the condition, state, or disease (e.g., preventing the onset of one or more symptoms of a cancer associated with MASTL).
[0023] The term "associated with" or "associated with" refers to a substance or substance activity or function associated with a disease (e.g., cancer) that is caused (in whole or in part) by the disease (e.g., cancer) or that the symptoms of the disease are caused (in whole or in part) by the substance or substance activity or function. For example, symptoms of a disease or condition associated with MASTL pathway activity can be symptoms that arise (in whole or in part) from increased activity levels of the MASTL protein pathway. As used herein, something described as associated with a disease can be a target for treatment of the disease if it is a causative agent. For example, a disease associated with increased activity levels of MASTL can be treated with an agent (e.g., a compound described herein) that is effective in reducing MASTL activity levels.
[0024] As defined herein, the terms "inhibition," "inhibit," "inhibiting," and the like, in reference to protein-inhibitor (e.g., antagonist) interactions, refer to a negative effect on the activity or level of function of a protein (e.g., a component of MASTL) relative to the activity or level of function of the protein pathway in the absence of the inhibitor. In some embodiments, inhibition refers to a reduction in a disease or disease symptom (e.g., cancer associated with increased activity of MASTL). In some embodiments, inhibition refers to a reduction in the activity level of a signaling pathway or signaling pathway associated with MASTL. Thus, inhibition may include, at least in part, partially or fully blocking a stimulus; reducing, preventing, or delaying activation; inactivating, desensitizing, or down-regulating signal transduction or enzyme activity or the amount of a protein (e.g., MASTL). Inhibition may include, at least in part, partially or totally reducing stimulation, reducing activation, modulating signal transduction or enzymatic activity, or levels of other proteins, or deactivating, desensitizing, or down-regulating the amount of proteins (e.g., components of the MASTL protein pathway) that can modulate cell survival, cell proliferation, or cell motility compared to non-diseased controls.
[0025] Throughout the description and claims of this specification, the words "comprise" and "contain" and variations thereof mean "including but not limited to" and are not intended to exclude other moieties, additives, components, integers or steps.
[0026] Throughout the description and claims of this specification, the singular includes the plural unless the context otherwise requires. In particular, where the indefinite article is used, the specification must be understood to contemplate the plural as well as the singular, unless the context otherwise requires.
[0027] The term "halo" or "halogen" refers to one of the halogens in Group 17 of the periodic table. In particular, the term refers to fluorine, chlorine, bromine, and iodine. Preferably, the term refers to fluorine or chlorine.
[0028] Term C m-n is a term that refers to a group having m to n carbon atoms.
[0029] The term “C 1-6 "Alkyl" is a term that refers to a linear or branched hydrocarbon chain containing 1, 2, 3, 4, 5, or 6 carbon atoms, for example, methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, sec-butyl, tert-butyl, n-pentyl, and n-hexyl. 1-4 "Alkyl" refers to a group containing up to four carbon atoms. An alkylene group is a divalent alkyl group, which in turn may be linear or branched and has two points of attachment to the remainder of the molecule. An alkylene group may also be, for example, one of the alkyl groups described in this paragraph. For example, C 1-6 Alkylene can be -CH-, -CHCH-, -CHCH(CH)-, -CHCHCH-, or -CHCH(CH)CH-. Alkyl and alkylene groups can be substituted or unsubstituted with one or more substituents. Possible substituents are described herein. For example, alkyl or alkylene group substituents can be halogen, such as fluorine, chlorine, bromine, and iodine, OH, C-C alkoxy, -NR'R'' amino, where R' and R'' are independently H or alkyl. Other substituents for alkyl groups can alternatively be used.
[0030] The term “C 1-6 "Haloalkyl," e.g., "C1-4 haloalkyl," refers to a hydrocarbon chain substituted with at least one halogen atom, selected independently at each occurrence, such as fluorine, chlorine, bromine, and iodine. The halogen atom may be located at any position on the hydrocarbon chain. For example, C 1-6Haloalkyl can refer to chloromethyl, fluoromethyl, trifluoromethyl, chloroethyl (e.g., 1-chloromethyl and 2-chloroethyl), trichloroethyl (e.g., 1,2,2-trichloroethyl and 2,2,2-trichloroethyl), fluoroethyl (e.g., 1-fluoromethyl and 2-fluoroethyl), trifluoroethyl (e.g., 1,2,2-trifluoroethyl and 2,2,2-trifluoroethyl), chloropropyl, trichloropropyl, fluoropropyl, and trifluoropropyl. Haloalkyl groups can be, for example, -CX, -CHX, -CHCX, -CHCHX, or -CX(CH)CH, where X is halo (e.g., F, Cl, Br, or I). Fluoroalkyl groups are hydrocarbon chains substituted with at least one fluorine atom (e.g., -CF, -CHF, -CHCF, or -CHCHF).
[0031] The term “C 2-6 "Alkenyl" includes a branched or linear hydrocarbon chain having at least one double bond and 2, 3, 4, 5, or 6 carbon atoms. The double bond may be present in the E or Z isomer. The double bond may be present in any possible position on the hydrocarbon chain. For example, "C 2-6 "Alkenyl" can be ethenyl, propenyl, butenyl, butadienyl, pentenyl, pentadienyl, hexenyl, and hexadienyl. An alkenylene group is a divalent alkenyl group, which in turn can be linear or branched and has two points of attachment to the remainder of the molecule. An alkenylene group can also be, for example, one of the alkenyl groups described in this paragraph. For example, an alkenylene can be -CH=CH-, -CHCH=CH-, -CH(CH)CH=CH-, or -CHCH=CH-. Alkenyl and alkenylene groups can be substituted or unsubstituted with one or more substituents. Possible substituents are described herein. For example, substituents can be those of alkyl groups described above.
[0032] The term “C 2-6"Alkynyl" includes a branched or linear hydrocarbon chain having at least one triple bond and 2, 3, 4, 5, or 6 carbon atoms. The triple bond may be present at any possible position on the hydrocarbon chain. For example, "C 2-6 "Alkynyl" can be ethynyl, propynyl, butynyl, pentynyl, and hexynyl. An alkynylene group is a divalent alkynyl group, which in turn can be linear or branched and has two points of attachment to the remainder of the molecule. An alkynylene group can also be, for example, one of the alkynyl groups described in this paragraph. For example, an alkynylene can be -C≡C-, -CHC≡C-, -CHC≡CCH-, -CH(CH)CH≡C-, or -CHC≡CCH. An alkynyl or alkynylene group can be substituted or unsubstituted with one or more substituents. Possible substituents are described herein. For example, the substituents can be those of an alkyl group, as described above.
[0033] The term “C 3-12 "Cycloalkyl" includes saturated hydrocarbon ring systems containing from 3 to 12 carbon atoms. Cycloalkyl groups may be single ring or fused, bridged, or spiro saturated hydrocarbon ring systems. The term "C 3-6 "Cycloalkyl" includes saturated hydrocarbon ring systems containing 3, 4, 5, or 6 carbon atoms. For example, C3-C 12 Cycloalkyl can be cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, bicyclo[1.1.1]pentane, bicyclo[2.1.1]hexane, bicyclo[2.2.1]heptane (norbornane), bicyclo[2.2.2]octane, or tricyclo[3.3.1.1]decane (adamantyl). For example, "C3-C6 cycloalkyl" can be cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, bicyclo[2.1.1]hexane, or bicyclo[1.1.1]pentane. Preferably, "C3-C6 cycloalkyl" can be cyclopropyl, cyclobutyl, cyclopentyl, or cyclohexyl.
[0034] The term “C 3-12"Cycloalkenyl" includes hydrocarbon ring systems containing 3 to 12 carbon atoms and at least one double bond (e.g., 1 or 2 double bonds). Cycloalkenyl groups can be single ring or fused, bridged, or spiro hydrocarbon ring systems. For example, C 3-12 The cycloalkenyl may be cyclobutenyl, cyclopentenyl, or cyclohexenyl.
[0035] The terms "heterocyclyl," "heterocyclic," or "heterocycle" include non-aromatic saturated or partially saturated single-ring or fused, bridged, or spiro bicyclic heterocyclic ring systems. Monocyclic heterocyclic rings may contain 1 to 5 (preferably 1, 2, or 3) heteroatoms selected from nitrogen, oxygen, or sulfur and 3 to 12 (preferably 3 to 7) ring atoms. Bicyclic heterocycles may contain 7 to 12-membered atoms in the ring. Bicyclic heterocyclic rings may be fused, spiro, or bridged ring systems. Heterocyclyl groups may be 3- to 9- (e.g., 3- to 7-) membered non-aromatic monocyclic or bicyclic saturated or partially saturated groups containing 3-12, e.g., 1, 2, or 3 heteroatoms independently selected from O, S, and N in the ring system (in other words, 1, 2, or 3 ring atoms selected from O, S, and N forming the ring system). Partially saturated means that the ring can be formed with one or two double bonds. This applies particularly to monocyclic rings having 5 to 7 members. The double bond is typically between two carbon atoms, but may also be between a carbon atom and a nitrogen atom. Bicyclic rings can be spiro-fused, i.e., the rings are connected to each other through a single carbon atom; vicinal-fused, i.e., the rings are connected to each other through two adjacent carbon or nitrogen atoms; or they can share a bridgehead, i.e., the rings are connected to each other through two non-adjacent carbon or nitrogen atoms (bridged ring system). Examples of heterocyclic groups include cyclic ethers such as oxiranyl, oxetanyl, tetrahydrofuranyl, and dioxanyl, as well as substituted cyclic ethers. Heterocycles containing at least one nitrogen in a ring position include, for example, azetidinyl, pyrrolidinyl, piperidinyl, piperazinyl, morpholinyl, thiomorpholinyl, tetrahydrotriazinyl, tetrahydropyrazolyl, tetrahydropyridinyl, homopiperidinyl, homopiperazinyl, 2,5-diaza-bicyclo[2.2.1]heptanyl, and the like.Common sulfur-containing heterocycles include tetrahydrothienyl, dihydro-1,3-dithiol, tetrahydro-2H-thiopyran, and hexahydrothiepin. Other heterocycles include dihydrooxathiolyl, tetrahydrooxazolyl, tetrahydro-oxadiazolyl, tetrahydrodioxazolyl, tetrahydrooxathiazolyl, hexahydrotriazinyl, tetrahydrooxazinyl, tetrahydropyrimidinyl, dioxolinyl, octahydrobenzofuranyl, octahydrobenzimidazolyl, and octahydrobenzothiazolyl. Sulfur-containing heterocycles also include oxidized sulfur heterocycles containing an SO or SO group. For example, sulfoxide and sulfone forms of tetrahydrothienyl and thiomorpholinyl, such as tetrahydrothienyl 1,1-dioxide and thiomorpholinyl 1,1-dioxide, are included. Suitable values for heterocyclyl groups containing one or two oxo (=O) are, for example, 2-oxopyrrolidinyl, 2-oxoimidazolidinyl, 2-oxopiperidinyl, 2,5-dioxopyrrolidinyl, 2,5-dioxoimidazolidinyl or 2,6-dioxopiperidinyl. In particular, the heterocyclyl group is a saturated monocyclic 3- to 7-membered heterocyclyl containing one, two or three heteroatoms selected from nitrogen, oxygen or sulfur, such as azetidinyl, tetrahydrofuranyl, tetrahydropyranyl, pyrrolidinyl, morpholinyl, tetrahydrothienyl, tetrahydrothienyl 1,1-dioxide, thiomorpholinyl, thiomorpholinyl 1,1-dioxide, piperidinyl, homopiperidinyl, piperazinyl or homopiperazinyl. As can be understood by those skilled in the art, any heterocycle can be linked to a different group via any suitable atom, such as a carbon or nitrogen atom. For example, the term "piperidino" or "morpholino" refers to a piperidin-1-yl or morpholin-4-yl ring linked via the ring nitrogen. For example, L. 1 Reference to "heterocyclylene", which may be represented by: refers to a divalent "heterocyclyl", for example, 3,2-morpholinylene.
[0036] The term "bridged ring system" includes ring systems in which two rings share two or more atoms, as seen, for example, in Advanced Organic Chemistry, by Jerry March, 4th Edition, Wiley Interscience, pages 131-133, 1992. Preferably, the bridge is formed between two non-adjacent carbon or nitrogen atoms in the ring system. The bridge connecting the bridge head atoms may be a bond and may contain one or more atoms. Examples of bridged heterocyclyl ring systems include aza-bicyclo[2.2.1]heptane, 2-oxa-5-azabicyclo[2.2.1]heptane, aza-bicyclo[2.2.2]octane, aza-bicyclo[3.2.1]octane, and quinuclidine.
[0037] The term "spirobicyclic ring system" includes ring systems in which two rings share one common spiro carbon atom, i.e., the heterocyclic ring is linked to an additional carbocyclic or heterocyclic ring through one common spiro carbon atom. Examples of spirocyclic ring systems include 3,8-diaza-bicyclo[3.2.1]octane, 2,5-diaza-bicyclo[2.2.1]heptane, 6-azaspiro[3.4]octane, 2-oxa-6-azaspiro[3.4]octane, 2-azaspiro[3.3]heptane, 2-oxa-6-azaspiro[3.3]heptane, 6-oxa-2-azaspiro[3.4]octane, 2,7-diaza-spiro[4.4]nonane, 2-azaspiro[3.5]nonane, 2-oxa-7-azaspiro[3.5]nonane, and 2-oxa-6-azaspiro[3.5]nonane.

[0040] The term "aromatic," when applied to the substituent as a whole, includes monocyclic or polycyclic ring systems having 4n+2 electrons in the complex π-system within the ring or ring system, with all atoms contributing to the complex π-system lying in the same plane.
[0041] The term "aryl" includes aromatic hydrocarbon ring systems. The ring systems have 4n+2 electrons in a complex π-system within the ring, with all atoms contributing to the complex π-system lying in the same plane. For example, "aryl" can be phenyl and naphthyl. The aryl system itself can be substituted with other groups.

The ring or ring system has 4n+2 electrons in a complex pi-system, with all atoms contributing to the complex pi-system lying in the same plane.
[0043] Examples of heteroaryl groups are monocyclic and bicyclic groups containing 5 to 12 ring members, more typically 5 to 10 ring members. Heteroaryl groups can be, for example, 5- or 6-membered monocyclic rings or 9- or 10-membered bicyclic rings, e.g., fused 5- and 6-membered rings or bicyclic structures formed by two fused 6-membered rings. Each ring can contain about four heteroatoms, typically selected from nitrogen, sulfur, and oxygen. Typically, heteroaryl rings contain up to three heteroatoms, more typically up to two, e.g., a single heteroatom. In one embodiment, a heteroaryl ring contains at least one ring nitrogen atom. The nitrogen atoms in a heteroaryl ring can be basic, as in the case of imidazole or pyridine, or essentially non-basic, as in the case of indole or pyrrole nitrogens. Generally, the number of basic nitrogen atoms present in a heteroaryl group, including optional ring amino group substitutions, will be fewer than five.
[0044] Examples of heteroaryl include furyl, pyrrolyl, thienyl, oxazolyl, isoxazolyl, imidazolyl, pyrazolyl, thiazolyl, isothiazolyl, oxadiazolyl, thiadiazolyl, triazolyl, tetrazolyl, pyridyl, pyridazinyl, pyrimidinyl, pyrazinyl, 1,3,5-triazenyl, benzofuranyl, indolyl, isoindolyl, benzothienyl, benzoxazolyl, benzimidazolyl, benzothiazolyl, benzothiazolyl, indazolyl, purinyl, and benzofurazanyl.

"Heteroaryl" also includes partially aromatic bi- or polycyclic ring systems which are non-aromatic, saturated, or partially saturated when at least one ring is aromatic and one or more other rings contain one or more heteroatoms selected from nitrogen, oxygen, or sulfur.Examples of partially aromatic heteroaryl groups include, for example, tetrahydroisoquinolinyl, tetrahydroquinolinyl, 2-oxo-1,2,3,4-tetrahydroquinolinyl, dihydrobenzothienyl, dihydrobenzofuranyl, 2,3-dihydro-benzo[1,4]dioxinyl, benzo[1,3]dioxolyl, 2,2-dioxo-1,3-dihydro-2-benzothienyl, 4,5,6,7-tetrahydrobenzofuranyl, indolinyl, 1,2,3,4-tetrahydro-1,8-naphthyridinyl, 1,2,3,4-tetrahydropyrido[2,3-b]pyrazinyl, and 3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazinyl.

[0049] The term "oxo" or "=O" as used herein means an oxygen that is double bonded to a carbon atom.
[0050] The term "optionally substituted" includes groups, structures, or molecules that are substituted and groups, structures, or molecules that are not substituted.
[0051] Where optional substituents are selected from "one or more" groups, this definition should be understood to include all substituents selected from one of the specified groups or substituents selected from two or more of the specified groups.
[0052] When a residue is substituted, the substitution may occur anywhere within the residue that is chemically feasible and consistent with the valency requirements of the atom. The residue may be substituted with one or more substituents, e.g., 1, 2, 3, or 4 substituents; optionally, one or two substituents are present in a group. When two or more substituents are present, the substituents may be the same or different.
[0053] Substituents are present only at chemically feasible positions, and those of ordinary skill in the art can determine (experimentally or theoretically) which substitutions are chemically feasible and which are not, without undue effort.
[0054] Ortho, meta and para substitutions are terms that are well known in the art. Without a doubt, an "ortho" substitution can refer to a simple group, such as the fluoro group in the example below, or to a bond terminal. [ka] Any other part of the molecule shown is a substitution pattern in which adjacent carbons have substituents. [ka] A "meta" substitution is a substitution pattern in which two substituents are located on carbons one carbon away from each other, i.e., there is one carbon atom between the substituted carbons. In other words, one substituent is located on the second atom from the one bearing a substituent. For example, the following group is meta-substituted: [ka] "Para" substitution is a substitution pattern in which two substituents are located on carbons separated by two carbon atoms, i.e., there are two carbon atoms between the substituted carbons. In other words, there is another substituent on the third atom from the atom bearing the substituent. For example, the following group is para-substituted: [ka] Reference to an -NRR' group forming a 4- to 6-membered heterocyclyl means that R and R' together with the nitrogen atom to which they are attached form a 4- to 6-membered heterocyclyl group. For example, -NR A1 R B1 , -NR A4 R B4 , -NR A5 R B5 , -NR 17 R B2 or -NR 20 R B3 A group such as -NRR' can be formed as follows: [ka] Similarly, the -NRR' group within the substituent may form a carbonyl-linked 4- to 6-membered heterocyclyl, for example, a -C(O)NRR' group can be formed as follows: [ka] -NRR' in substituents such as -OC(O)NRR', -SO2NRR' and -NRC(O)NRR', - may similarly form 4- to 6-membered heterocyclyl in these substituents.
[0055] "Compounds of the invention" means any compound disclosed generally or specifically herein. Thus, compounds of the invention include compounds of formula (I), (II), (III), (IV), (V), (VI), (VII), or (VIII) and compounds of the Examples.
[0056] [ka] or a bond ending in "*" indicates that the bond is connected to another atom not shown in the structure. A bond that ends within a cyclic structure but does not terminate at an atom of the ring structure indicates that the bond can be connected to any of the atoms of the ring structure as allowed by the valences.
[0057] It should be understood that features, integers, traits, compounds, chemical moieties, or groups described in connection with any embodiment or illustration of the present invention are applicable to any other embodiment or illustration described herein, except to the extent that they cannot be used in conjunction with one another.

[0059] The various functional groups and substituents comprising the compounds of the present invention are generally selected so that the molecular weight of the compound does not exceed 1000. More typically, the molecular weight of the compound will be less than 750, e.g., less than 700, or less than 650, or less than 600, and more preferably less than 550.
[0060] A suitable or preferred feature of any compound of the invention may also be a suitable feature of any other aspect.
[0061] The present invention contemplates pharmaceutically acceptable salts of the compounds of the present invention. These may include acid addition and base salts of the compounds. These may be acid addition and base salts of the compounds.
[0062] Suitable acid addition salts are formed from acids which form non-toxic salts. Examples include acetate, aspartate, benzoate, besylate, bicarbonate / carbonate, bisulfate / sulfate, borate, camsylate, citrate, edisylate, esylate, formate, fumarate, gluceptate, gluconate, glucuronic acid, hexafluorophosphate, hybenzate, hydrochloride / chloride, hydrobromide / bromide, hydroiodide / iodide, isethionate, lactate, malate, maleate, malonate, mesylate, methylsulfate, naphthylate, 1,5-naphthalenedisulfonate, 2-napsylate, nicotinate, nitrate, orotate, oxalate, palmitate, pamoate, phosphate / hydrogenphosphate / dihydrogenphosphate, saccharate, stearate, succinate, tartrate, tosylate, and trifluoroacetate.
[0063] Suitable base salts are formed from bases that form non-toxic salts. Examples include aluminum, arginine, benzathine, calcium, choline, diethylamine, diolamine, glycine, lysine, magnesium, meglumine, olamine, potassium, sodium, tromethamine, and zinc salts. Hemisalts of acids and bases may form, for example, hemisulfate and hemicalcium salts. For a review of suitable salts, see Stahl and Wermuth, "Handbook of Pharmaceutical Salts: Properties, Selection, and Use" (Wiley-VCH, Weinheim, Germany, 2002).
[0064] Pharmaceutically acceptable salts of the compounds of the present invention can be prepared, for example, by one or more of the following methods: (i) reacting a compound of the present invention with a desired acid or base; (ii) removing an acid- or base-labile protecting group from a suitable precursor of a compound of the invention, or ring-opening a suitable cyclic precursor, e.g., a lactone or lactam, using a desired acid or base; or (iii) Conversion of one salt of a compound of the invention into another by reaction with an appropriate acid or base or by a suitable ion exchange column.
[0065] Such methods are generally carried out in solution. The salts produced can be precipitated and recovered by filtration or by evaporation of the solvent. The degree of ionization of the salts produced can vary from completely ionized to almost non-ionized.
[0066] Compounds that have the same molecular formula but differ in the nature or sequence of atomic bonding or the arrangement of their atoms in space are called "isomers." Isomers that differ in the arrangement of their atoms in space are called "stereoisomers." Stereoisomers that are not mirror images of each other are called "partial stereoisomers," and those that are non-superimposable mirror images of each other are called "enantiomers." When a compound has an asymmetric center, for example, when it is bonded to four other groups, a pair of enantiomers is possible. Enantiomers can be characterized by the absolute configuration of the asymmetric center and described by Cahn and Prelog's R- and S-ordering rules or the way molecules rotate the plane of polarized light and are designated as right- and left-handed (i.e., as (+)- or (-)-isomers, respectively). Chiral compounds can exist as individual enantiomers or mixtures thereof. A mixture containing equal proportions of enantiomers is called a "racemic mixture." When a compound of the present invention has two or more stereocenters, a combination of (R) and (S) stereoisomers is contemplated. The combination of (R) and (S) stereoisomers can produce a stereoisomeric mixture or a single stereoisomer. The compound of the present invention can exist as a single stereoisomer or can be a mixture of stereoisomers, such as a racemic mixture, other enantiomeric mixtures, and partial stereoisomeric mixtures. When the mixture is an enantiomeric mixture, the enantiomeric excess can be any one of those disclosed above. When the compound is a single stereoisomer, the compound can contain other stereoisomers or enantiomers as impurities. Thus, a single stereoisomer need not necessarily have 100% enantiomeric excess (ee) or partial stereoisomeric excess (de), but can have about 85%, e.g., at least 90%, at least 95%, or at least 99% of the isomer.
[0067] The compounds of the present invention may have one or more asymmetric centers, and therefore, such compounds can be produced as individual (R)- or (S)-stereoisomers or mixtures thereof. Unless otherwise specified, the description or name of a particular compound in the specification and claims is intended to include all individual enantiomers and mixtures thereof, racemic or otherwise. Methods for the determination of stereochemistry and separation of stereoisomers are well known in the art, for example, by synthesis from optically active starting materials or resolution of racemic forms (see discussion in Chapter 4 of "Advanced Organic Chemistry," 4th edition, J. March, John Wiley and Sons, New York, 2001). Some of the compounds of the present invention may have centers of geometric isomerism (E- and Z-isomers). The present invention should be understood to include all optical, regioisomers, and geometric isomers and mixtures thereof that possess MASTL inhibitor activity.
[0068] Z / E (eg, cis / trans) isomers can be separated by conventional techniques well known to those skilled in the art, such as chromatography and fractional crystallization.
[0069] Conventional techniques for the preparation / separation of individual enantiomers, if necessary, include chiral synthesis from suitable optically pure precursors or resolution of the isomers (or isomers of salts or derivatives) using, for example, chiral high-performance liquid chromatography (HPLC). Thus, the chiral compounds of the present invention (and their chiral precursors) can be obtained in enantiomerically enriched form using chromatography, typically HPLC, on an asymmetric resin with a mobile phase composed of a hydrocarbon, typically heptane or hexane, containing 0-50% isopropanol, typically 2-20%, and, as a specific example, 0-5% alkylamine, e.g., 0.1% diethylamine. Concentration of the eluate provides the enriched mixture.
[0070] Alternatively, the racemate (or racemic precursor) can be reacted with a suitable optically active compound, for example, an alcohol, or, if the compound of the invention contains an acidic or basic moiety, with a base or acid, such as 1-phenylethylamine or tartaric acid. The resulting mixture of partial stereoisomers can be separated by chromatography and / or fractional crystallization, and one or both of the partial stereoisomers can be converted into the corresponding pure enantiomers by means well known to those skilled in the art.
[0071] When any racemate is crystallized, two other types can be determined. The first type is the racemate (actually the racemate) mentioned above, in which one homogeneous form of crystals containing the two enantiomers in equimolar amounts is produced. The second type is a racemic mixture or composite in which two forms of crystals are produced in equimolar amounts, each containing a single enantiomer.
[0072] The two crystalline forms present in a racemic mixture have identical physical properties, but may have different physical properties compared to the actual racemate. Racemic mixtures can be separated by conventional techniques well known to those skilled in the art. See, for example, "Stereochemistry of Organic Compounds" by EL Eliel and SH Wilen (Wiley, 1994).
[0073] The compounds and salts described herein may be isotopically labeled (or "radiolabeled"). Thus, one or more atoms are replaced with atoms having an atomic mass or mass number different from the atomic mass or mass number typically found in nature. Examples of radionuclides that may be incorporated include: 2 H (also written as "D" for deuterium), 3 H (also written as "T" for tritium), 11 C. 13 C. 14 C. 15 O. 17 O.18 O. 13 N, 15 N, 18 F, 36 Cl, 123 I, 25 I, 32 P, 35 The radionuclide used will depend on the specific application of the radiolabeled derivative in question. For example, for in-vitro competition assays, 3 H or 14 C is often useful. For radio-imaging applications, 11 C or 18 F is often useful. In some embodiments, the radionuclide is 3 H. In some embodiments, the radionuclide is 14 C. In some embodiments, the radionuclide is 11 C. And in some embodiments, the radionuclide is 18 It's F.
[0074] Isotopically labeled compounds can be prepared by processes similar to those described, using conventional techniques generally known to those skilled in the art or substituting the appropriate isotopically labeled reagent for a previously used non-labeled reagent.
[0075] Selective substitution of deuterium for hydrogen in a compound can modulate the metabolism of the compound, the PK / PD properties of the compound, and / or the toxicity of the compound. For example, deuteration can increase the half-life or decrease the solubility of the compound in vivo. Deuteration can also reduce the formation of toxic metabolites, improving safety and durability. The present invention should be understood to include deuterated derivatives of compounds of general formula (I). As used herein, the term deuterated derivative refers to a compound of the present invention in which at least one hydrogen atom at a specific position is replaced with deuterium. For example, C 1-4 -One or more hydrogen atoms of the alkyl group are replaced with deuterium to form a deuterated C 1-4- may form an alkyl group.
[0076] Certain compounds of the present invention may exist in solvated as well as undissolved forms, such as, for example, hydrated forms, and it should be understood that the present invention encompasses all such solvated forms that possess MASTL inhibitory activity.
[0077] Additionally, certain compounds of the present invention may exhibit polymorphism, and it should be understood that the present invention encompasses all such forms that possess MASTL inhibitory activity.
[0078] The compounds of the present invention can exist in many different tautomeric forms, and reference to a compound of the present invention includes all such forms. Without question, the compounds of the present invention can exist in one of many tautomeric forms, and if only one is specifically described or presented, all others are nevertheless included in the compounds of the present invention. Examples of tautomeric forms include keto-, enol-, and enolate-forms, such as the following tautomeric pairs: keto / enol (illustrated below), imine / enamine, amide / iminoalcohol, amidine / amidine, nitroso / oxime, thioketone / enethiol, and nitro / aci-nitro. [ka]
[0079] Amino-substituted triazines can exhibit hindered rotation about the SP2 carbon-N bond, generating regioisomers (blocked rotamers) (Amm et al. (1998), Mag. Reson. Chem. 36 587-596). Reference to compounds of the present invention includes all blocked rotamer forms of such compounds.
[0080] The in vivo effects of the compounds of the invention may be exerted in part by one or more metabolites formed in the human or animal body following administration of the compounds of the invention.
[0081] Furthermore, it should be understood that suitable pharmaceutically acceptable pro-drugs of the compounds of general formula (I) also form an aspect of the present invention. Accordingly, the compounds of the present invention include pro-drug forms of the compounds, and the compounds of the present invention can be administered in the form of pro-drugs (i.e., compounds that are broken down in the human or animal body to release the compounds of the present invention). Pro-drugs may be used to alter the physical and / or pharmacokinetic properties of the compounds of the present invention. Pro-drugs can be formed when the compounds of the present invention contain a suitable group or substituent to which a property-modifying group can be attached. Examples of pro-drugs include biotransferable ester derivatives that can be formed at carboxyl or hydroxy groups in the compounds of the present invention and biocleavable amide derivatives that can be formed at carboxyl or amino groups in the compounds of the present invention.

[0205] In certain embodiments, the present invention provides a compound selected from any one of the embodiments herein, or a pharmaceutically acceptable salt thereof.
[0206] Pharmaceutical Composition In yet another aspect, the present invention provides a pharmaceutical composition comprising a compound of the present invention, or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable excipient.
[0207] Conventional procedures for the selection and preparation of suitable pharmaceutical compositions are described, for example, in "Pharmaceuticals - The Science of Dosage Form Designs", MEAulton, Churchill Livingstone, 1988.
[0208] The compositions of the invention may be in a form suitable for oral use (e.g., tablets, troches, hard or soft capsules, aqueous or oily suspensions, emulsions, dispersible powders or granules, syrups or elixirs), topical use (e.g., creams, ointments, gels or aqueous or oily solutions or suspensions), administration by inhalation (e.g., finely divided powders or liquid aerosols), administration by inhalant (e.g., finely divided powders) or parenteral administration (e.g., sterile aqueous solutions for intravenous, subcutaneous, intramuscular or intraperitoneal administration or suppositories for rectal administration).
[0209] The compositions of the present invention can be prepared in a conventional manner using conventional pharmaceutical excipients well known in the art. Thus, compositions intended for oral use may contain, for example, one or more coloring, sweetening, flavoring and / or preservative agents.
[0210] An effective amount of a compound of this invention for use in treating a disease is an amount sufficient to cause a warm-blooded animal, especially a human, to symptomatically alleviate or slow the progression of the disease.
[0211] The amount of active ingredient that is combined with one or more excipients to produce a single dosage form will vary depending on the host treated and the particular route of administration. For example, a formulation intended for oral administration to humans will generally contain from 0.1 mg to 0.5 g (more suitably, 0.5 to 100 mg, e.g., 1 to 30 mg) of active agent formulated in any appropriate and convenient manner, and the amount of excipient may vary from about 5 to about 98% by weight of the total composition.
[0212] The magnitude of the dose of the compounds of the present invention administered for therapeutic or prophylactic purposes will vary according to well-known medical principles depending on the nature and severity of the disease, the age and sex of the animal or patient, and the route of administration.
[0213] When the compounds of the present invention are used for therapeutic or prophylactic purposes, they are generally administered in a range of daily dosages, for example, selected from 0.1 mg / kg to 100 mg / kg, 1 mg / kg to 750 mg / kg, 1 mg / kg to 600 mg / kg, 1 mg / kg to 550 mg / kg, 1 mg / kg to 75 mg / kg, 1 mg / kg to 50 mg / kg, 1 mg / kg to 20 mg / kg, or 5 mg / kg to 10 mg / kg, and if necessary, administered in divided doses.
[0214] Generally, lower dosages are administered when parenteral routes are used. Thus, for example, for intravenous, subcutaneous, intramuscular, or intraperitoneal administration, dosages in the range of 0.1 mg / kg to 30 mg / kg of body weight are generally used. In certain embodiments, the compounds of the present invention are administered intravenously at a daily dose of, for example, 1 mg / kg to 750 mg / kg, 1 mg / kg to 600 mg / kg, 1 mg / kg to 550 mg / kg, or 5 mg / kg to 550 mg / kg, e.g., approximately 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 125, 150, 175, 180, 200, 225, 250, 275, 300, 350, 400, 450, 500, 540, 550, or 575 mg / kg. Similarly, for administration by inhalation, a dose in the range of, for example, 0.05 mg / kg to 25 mg / kg body weight should be used. Preferably, the compounds of the present invention are administered orally, for example, in tablet or capsule dosage form. The daily oral dosage may be, for example, a total daily dosage selected from 1 mg to 1000 mg, 5 mg to 1000 mg, 10 mg to 750 mg, or 25 mg to 500 mg. Typically, a unit dosage form will contain approximately 0.5 mg to 0.5 g of the compound of the present invention. In certain embodiments, the compounds of the present invention are administered parenterally, for example, by intravenous administration. In certain other embodiments, the compounds of the present invention are administered orally.
[0215] Therapeutic Uses and Applications According to another aspect, the present invention provides a compound of the invention, or a pharmaceutically acceptable salt thereof, for use as a medicament.
[0216] A further aspect of the present invention provides a compound of the present invention, or a pharmaceutically acceptable salt thereof, for use in the treatment of a disease or medical condition mediated by serine / threonine-like kinase (MASTL).
[0217] Also provided is the use of a compound of the invention, or a pharmaceutically acceptable salt thereof, in the manufacture of a medicament for the treatment of a disease or medical condition mediated by serine / threonine-like kinase (MASTL).
[0218] Also provided is a method for treating a disease or medical condition mediated by MASTL in a subject in need thereof, the method comprising administering to the subject an effective amount of a compound of the invention, or a pharmaceutically acceptable salt thereof.
[0219] The following paragraphs provide criteria for the application of the compounds of the present invention, or pharmaceutically acceptable salts thereof, for use in treating specific diseases or conditions. Any reference herein to a compound for a specific use should be understood to be intended for (i) the use of a compound of the present invention, or a pharmaceutically acceptable salt thereof, in the manufacture of a medicament for treating the disease or condition in question; and (ii) a method of treating a disease or condition in a subject, comprising administering to the subject a therapeutically effective amount of a compound of the present invention, or a pharmaceutically acceptable salt thereof.
[0220] The MASTL-mediated medical condition disease can be any of the diseases or medical conditions listed in this application, such as a proliferative disorder, in particular cancer.
[0221] The subject to which the compounds of the present invention are administered may be a warm-blooded mammal, such as a human or animal. In certain embodiments, the subject or patient is a human. In other embodiments, the subject is an animal, such as a rat, dog, cat, primate, or horse.
[0222] The association of MASTL with human and animal diseases is clearly set forth in the background of the present invention. The contents of this specification and related references are intended to provide further support for the therapeutic use of the compounds of the present invention. Such supporting evidence linking MASTL to diseases and conditions also forms part of the disclosure for the utility of the compounds of the present invention in treating and preventing the medical conditions described herein.
[0223] Proliferative disorders MASTL has been shown to play a role in many diseases, including various cancers, and there is growing interest in using MASTL inhibitors as a therapeutic strategy (Marzec and Burgess, The Oncogenic Functions of MASTL Kinase, Front Cell Dev. Biol. (2018);6:162). This is supported by the observation that MASTL inhibition can reduce tumor growth in vitro and in vivo (Wang et al., (2014), Vera et al., (2015), Anania et al., (2015), Alvarez-Fernandez et al., (2018)). MASTL depletion has been shown to increase the radiosensitivity of breast cancer cells and reduce the formation of radioresistant breast cancer cells, suggesting a therapeutic combination of MASTL inhibitors and radiation therapy (Yoon et al., "MASTL inhibition promotes mitotic catastrophe through PP2A activation to inhibit cancer growth and radioresistance in breast cancer cells," BMC Cancer (2018) 18, 716). Knockdown of MASTL has also been shown to reduce the viability of thyroid cancer cells without significantly affecting normal cell proliferation (Anania et al., 2015), suggesting that MASTL inhibitors may also be relatively nontoxic.
[0224] In certain embodiments, the compounds of the present invention are for use in the treatment of proliferative disorders, including cancer and benign proliferative disorders.
[0225] cancer In certain embodiments, the compounds of the invention are for use in preventing or inhibiting cancer progression, for example, through preventing or inhibiting cancer cell migration, cancer cell invasion and / or cancer metastasis.

Am. J. Cancer Research. 2015;5(10):2929-2943).
[0232] In one embodiment, the compound of the invention, or a pharmaceutically acceptable salt thereof, is for use in treating a cancer selected from pancreatic cancer, triple-negative breast cancer (i.e., the tumor is estrogen receptor negative, progesterone receptor negative, and HER2 negative), hormone-refractory prostate cancer, and non-small cell lung cancer.
[0233] The compounds of the present invention provide anti-cancer effects against cancer (e.g., any of the cancers disclosed herein) selected from one or more of an anti-proliferative effect, a pro-apoptotic effect, an anti-mitotic effect, an anti-angiogenic effect, inhibition of cell migration, inhibition or prevention of tumor invasion and / or prevention or inhibition of metastasis.
[0234] The compounds of the present invention can be used to prevent or inhibit cancer progression. The compounds of the present invention may be used to slow, delay, or halt cancer progression. Cancer progression is generally determined by assigning stages to cancer. The stages are generally numbered from I to IV, with I representing isolated cancer and IV representing the stage of disease progression in which the cancer has metastasized to other organs. The stages generally take into account the size of the tumor, whether adjacent organs have been affected, whether lymph nodes have metastasized, etc. Preventing or inhibiting cancer progression is particularly important for preventing cancer spread, for example, from stage I to stage II, in which cancer spreads locally, or from stage III to stage IV, in which cancer metastasizes to other organs.
[0235] The compounds of the invention may be for use in the treatment of cancer, wherein the cancer is a primary cancer, which may be a second primary cancer.
[0236] The compounds of the invention may be for use in preventing or inhibiting the development of second primary cancers.
[0237] The compounds of the invention may be for use in treating cancers that are refractory (resistant) to anti-cancer drugs (e.g., chemotherapy) and / or radiation therapy. The cancer may be resistant initially to treatment or may develop resistance during treatment.
[0238] The compounds of the present invention are intended to be used in the treatment of cancer, wherein the cancer is a recurrent cancer, which may be local, regional or distant. A recurrent cancer is a cancer that recurs after a period of time in which the cancer cannot be found after initial treatment. The same cancer can recur in the same tissue or in another part of the body.
[0239] The compounds of the invention may be for use in preventing or inhibiting the recurrence of cancer.
[0240] The compounds of the invention may be for use in the treatment of cancer, wherein the cancer is a metastatic or secondary cancer.
[0241] The compounds of the present invention may be used to prevent or inhibit cancer metastasis. The treatment for metastatic cancer may be the same or different from the treatment previously used to treat the primary tumor. For example, in certain embodiments, the primary tumor may be surgically resected, and the compounds of the present invention are used to prevent the spread of cancer cells that remain after surgery or that have already escaped from the primary tumor. In other embodiments, the primary tumor may be treated using radiation therapy. In other embodiments, the primary tumor may be treated with chemotherapy. Combination therapies are commonly used to treat cancer, generally to maximize the length and depth of remission. Any combination therapy disclosed herein may be used with the compounds of the present invention.
[0242] If a primary tumor has already metastasized and a secondary tumor has formed, the compounds of the present invention may be used to treat the secondary tumor. This can include both treating the secondary tumor and preventing secondary tumor metastasis. Reference to metastasis herein is intended to encompass metastasis of any tumor disclosed herein. Generally, the secondary tumor will be in a different tissue than the primary tumor. For example, the secondary tumor may be a secondary bone tumor. In certain embodiments, the compounds of the present invention are intended for use in treating secondary bone tumors, e.g., secondary bone tumors where the primary tumor is a breast or prostate tumor.
[0243] Benign proliferative disorders The compounds of the present invention, or pharmaceutically acceptable salts thereof, may be used to treat benign proliferative diseases. The benign diseases may be benign tumors, such as hemangioma, hepatocellular adenoma (HCA), cavernous hemangioma, focal nodular hyperplasia, acoustic neuroma, neurofibroma, bile duct adenoma, cholangiocytoma, fibroma, lipoma, myoma, mesothelioma, teratoma, myxoma, nodular regenerative hyperplasia, trachoma, pyogenic granuloma, mole, uterine fibroid, thyroid adenoma, adrenal cortical adenoma, or pituitary adenoma.
[0244] In some embodiments, the benign proliferative disease is a hyperproliferative skin disorder, including psoriasis, warts, keratoacanthoma, seborrhea, ichthyosis, actinic keratosis, Bowen's disease, papilloma, seborrheic keratosis, eczema, atopic dermatitis, keloids, and epidermolysis bullosa (EB).
[0245] Other diseases and conditions In certain embodiments, the compounds of the invention are for use in the treatment or prevention of metabolic disorders, or symptoms or conditions associated with metabolic disorders.
[0246] The metabolic disorder may be a glucose metabolism disorder or a weight disorder.
[0247] The term "glucose metabolism disorder" includes all disorders characterized by a clinical symptom or combination of clinical symptoms associated with elevated levels of glucose and / or elevated levels of insulin in healthy individuals and related subjects. Elevated glucose and / or insulin levels can be manifested in the following diseases, disorders and conditions, among others: hyperglycemia, type 2 diabetes, gestational diabetes, type 1 diabetes, insulin resistance, impaired glucose tolerance, hyperinsulinemia, impaired glucose metabolism, pre-diabetes, other metabolic disorders (such as metabolic syndrome), and obesity.
[0248] The term "insulin resistance," as used herein, refers to a condition in which normal amounts of insulin fail to produce normal physiological or molecular responses.
[0249] The term "hyperglycemia," as used herein, refers to a condition in which high amounts of glucose circulate in the plasma of a healthy individual. Hyperglycemia can be diagnosed using methods known in the art, including measuring fasting blood glucose levels.
[0250] The term "hyperinsulinemia," as used herein, refers to a condition in which circulating insulin levels are elevated in conjunction with elevated or normal blood glucose levels. Hyperinsulinemia can be caused by insulin resistance associated with dyslipidemia, such as high triglycerides, high cholesterol, high low-density lipoprotein (LDL), and low high-density lipoprotein (HDL); high uric acid levels; polycystic ovary syndrome; type 2 diabetes; and obesity. Hyperinsulinemia can be diagnosed when plasma insulin levels are 2 μg / ml or higher.
[0251] The term "weight disorder" refers to a condition associated with excessive weight and / or increased appetite. Various parameters are used to determine whether a subject is overweight compared to a healthy person, including the subject's age, height, sex, and health status. For example, a subject can be considered overweight or obese by assessing the subject's body mass index (BMI), which is calculated by dividing the subject's height by their weight. Adults with a BMI ranging from -18.5 to -24.9 kg / m can be considered normal weight; adults with a BMI between -25 and -29.9 kg / m can be considered overweight (pre-obese); and adults with a BMI of -30 kg / m or greater can be considered obese. Thus, in some embodiments, the weight disorder is obesity.
[0252] Thus, symptoms and conditions associated with metabolic disorders may include, but are not limited to, increased blood sugar (hyperglycemia), decreased insulin production, metabolic syndrome, increased cholesterol, increased triglyceride levels, heart disease, stroke, high blood pressure, increased risk of blood clots (e.g., deep vein thrombosis), diabetes, metabolic acidosis, diabetic neuropathy, diabetic nephropathy, diabetic retinopathy, diabetic cardiomyopathy, and the like.
[0253] The term "metabolic syndrome" refers to a cluster of related traits, including, but not limited to, hyperinsulinemia, abnormal glucose tolerance, fat redistribution to the abdominal or upper body compartment, hypertension, abnormal fiber breakdown, and dyslipidemia, which are characterized by elevated triglycerides, low high-density lipoprotein (HDL) cholesterol, and elevated low-density lipoprotein (LDL) particles. Subjects with metabolic syndrome are at risk for developing type 2 diabetes and / or other disorders, such as atherosclerosis.
[0254] The compounds of the invention may be used to prevent or inhibit the progression or symptoms of metabolic disorders or conditions associated therewith. For example, the compounds of the invention may lower blood glucose, insulin, triglyceride, or cholesterol levels to ranges found in healthy subjects; reduce weight; improve glucose tolerance, energy expenditure, or insulin sensitivity; delay the onset or progression of diabetes; reduce blood pressure; and / or reduce the risk of blood clots, heart disease, or stroke.
[0255] In certain embodiments, the compounds of the present invention are for use in treating a platelet disorder, such as thrombocytopenia.
[0256] The compounds of the present invention may be used alone or in combination with one or more anti-cancer agents and / or radiation therapy, as described herein.
[0257] Combination therapy The compounds of the present invention may be used alone to provide a therapeutic effect. The compounds of the present invention may also be used in conjunction with one or more additional therapies.
[0258] In some embodiments, the compounds of the present invention are used in combination with one or more anti-cancer agents and / or radiation therapy.
[0259] The rationale for this is based on results showing that overexpression of MASTL is associated with resistance to cisplatin ( Wang et al., 2014 ) by accelerating checkpoint recovery ( Wong et al., 2016 ). Conversely, knockdown of MASTL has been observed to sensitize cancer cells to cisplatin, radiation therapy, and 5-fluorouracil (5FU) in various cancer types (Wang et al., (2014)). Serine / threonine kinase (MASTL kinase), a promising therapeutic target, promotes cancer recurrence (Oncotarget511479-11489; Nagel et al., (2015)). Genome-wide siRNA screens confirm the radiation-reducing effects of downregulating MASTL and FOXM1 in NSCLC (Mol. Cancer Ther.141434-1444; Uppada et al. (2018)). MASTL promotes Wnt / β-catenin signaling to induce colorectal cancer progression and chemoresistance (Mol. Cancer17:111; Yoon et al., (2018)). MASTL inhibition promotes mitotic catastrophe through PP2A activation to inhibit cancer growth and radioresistance in breast cancer cells.BMC Cancer18:716).
[0260] Therefore, the compounds of the present invention can be used to prevent or reduce cellular resistance to anti-cancer drugs, including chemotherapeutic agents and radiation therapy.

[0276] Biological Assays The biological effect of a compound can be assessed using one of the assays described in the Examples herein.
[0277] In certain embodiments, compounds have a pIC of 7.0 or less in the MASTLwt activity assay described in the Examples. 50 It has.
[0278] Synthesis The compounds of the present invention can be prepared using methods similar to the general synthetic methods described in the Examples. In the descriptions of the synthetic methods described below and the descriptions of the reference synthetic methods used to prepare starting materials, it should be understood that all reaction conditions proposed, including the selection of solvents, reaction pressure, reaction temperature, duration of experiments, and work procedures, can be selected by those skilled in the art.
[0279] One skilled in the art of organic synthesis understands that the functionality present on various portions of the molecule must be compatible with the reagents and reaction conditions.
[0280] Necessary starting materials can be obtained by standard procedures of organic chemistry. The preparation of such starting materials is illustrated within the following representative process variants and accompanying examples. Alternatively, necessary starting materials can be obtained through procedures analogous to those illustrated, within the ordinary skill of an organic chemist.
[0281] It will be appreciated that during the synthesis of the compounds of the invention, or of particular starting materials, in the steps defined below, it may be desirable to protect certain substituents to prevent these undesired reactions, and the skilled chemist will recognize when such protection is required and how to place or subsequently remove such protecting groups.
[0282] For examples of protecting groups, see, for example, 'Protective Groups in Organic Synthesis' by Theodora Green (publisher: John Wiley & Sons), among many other general works on the subject. Protecting groups can be removed by any convenient method known to skilled chemists to be suitable for removing the protecting group in question, chosen to effect removal of the protecting group while minimizing interference with groups elsewhere in the molecule.
[0283] Thus, if reactants contain groups such as amino, carboxy or hydroxy, it may be preferable to protect the group in some of the reactions mentioned herein.
[0284] For example, suitable protecting groups for amino or alkylamino groups are, for example, acyl groups, e.g., alkanoyl groups such as acetyl or trifluoroacetyl, alkoxycarbonyl groups, e.g., methoxycarbonyl, ethoxycarbonyl, or t-butoxycarbonyl groups, allylmethoxycarbonyl groups, e.g., benzyloxycarbonyl, or aroyl groups, e.g., benzoyl. The deprotection conditions for protecting groups necessarily vary depending on the choice of protecting group. Thus, for example, acyl groups, such as alkanoyl or alkoxycarbonyl groups or aroyl groups, can be removed by hydrolysis using a suitable base, e.g., an alkali metal hydroxide, e.g., lithium or sodium hydroxide. Alternatively, acyl groups such as tert-butoxycarbonyl groups may be removed by treatment with a suitable acid, for example, sulfur or phosphoric acid or trifluoroacetic acid, and allylmethoxycarbonyl groups such as benzyloxycarbonyl groups may be removed by hydrogenation over a catalyst such as palladium-on-carbon or by treatment with a Lewis acid such as BF3.OEt2. A suitable alternative protecting group for a primary amino group is, for example, a phthaloyl group which may be removed by treatment with an alkylamine, for example, dimethylaminopropylamine, or hydrazine.
[0285] Suitable protecting groups for hydroxy groups include, for example, acyl groups, e.g., alkanoyl groups such as acetyl, aroyl groups such as benzoyl, or arylmethyl groups such as benzyl. The deprotection conditions for such protecting groups necessarily vary depending on the choice of protecting group. Thus, for example, acyl groups, e.g., alkanoyl or aroyl groups, can be removed by hydrolysis with a suitable salt, e.g., an alkali metal hydroxide, e.g., lithium or sodium hydroxide, or ammonia. Alternatively, arylmethyl groups, e.g., benzyl groups, can be removed by hydrogenation over a catalyst, e.g., palladium-on-carbon.
[0286] Suitable protecting groups for carboxyl groups are, for example, esterifying groups, such as methyl or ethyl groups, which may be removed by hydrolysis with a salt such as sodium hydroxide, or, for example, t-butyl groups, which may be removed by treatment with an acid, for example, an organic acid such as trifluoroacetic acid, or, for example, benzyl groups, which may be removed by hydrogenation over a catalyst such as palladium on carbon.
[0287] The resin can also be used as a protecting group.
