Definitions

  • This disclosure relates generally to therapeutics which play a crucial role in the control of the cell cycle and more particularly, compounds that inhibit cyclin-dependent kinases (CDK).
  • CDK cyclin-dependent kinases
  • the disclosure also provides pharmaceutically acceptable compositions comprising compounds of the present disclosure and methods of using said compositions in the treatment of diseases associated with these pathways.
  • the cell cycle is a period between the successive divisions of a cell. During this period, the contents of the cell must be accurately replicated.
  • the processes that permit the cell to divide are very precisely controlled by a multitude of enzymatic reactions amongst which the protein kinase-triggered protein phosphorylation plays a major role.
  • there are four main stages/phases of cell cycle namely the Gap-1 (G1) phase, Synthesis (S) phase, Gap-2 (G2) and Mitosis (M) phases.
  • An extended phase of Gap-1 phase is coined as Gap-0 (G0) phase or Resting phase (Cancers 2014, 6, 2224-2242).
  • Cyclin- dependent kinases constitute a heterodimeric family of serine/threonine protein kinases involved in cell cycle and transcription. They include two main groups: cell cycle CDK and transcriptional CDK. The functionality of CDK depends on specific interactions with regulatory proteins named cyclins which form heterodimeric complexes with their partners. These complexes are important regulators of the cellular processes, especially in the cell cycle progression.
  • CDK5 is the prototype of atypical CDK: it is activated by the non-cyclin proteins p35 (or Cdk5Rl) and p39 (or Cdk5R2) and has unique post-mitotic functions in neuronal biology, angiogenesis and cell differentiation.
  • Proliferative signals induce the transition from the GO or G1 phases into S phase through the activation of the structurally related CDK4 and CDK6 [Development, 2013;140 (15):3079-93, Biochem Pharmacol 2012;84(8):985-93, Nature 2014;510(7505):393-6].
  • the binding of cyclin D to CDK4 and to CDK6 promotes the phosphorylation of the transcriptional repressor retinoblastoma protein (RB1).
  • CDK hyperactivity is often observed in cancer, reflecting their prominent role in cell cycle and transcription regulation.
  • cancer cells the process of cell division becomes unregulated, resulting in uncontrolled growth that leads to the development of a tumor.
  • a number of mechanisms contribute to the dysregulation of the cell cycle in malignant cells, including the amplification and hyperactivity of CDK4/6, or their genomic instability, which might cause CDK4/6 to become oncogenic drivers of cell replication. Usurping these mechanisms, cancer cells can continue to replicate by triggering the G1 to S phase transition. This process appears to be facilitated by a shortening of the G1 phase.
  • CDK4/6 antagonizes intrinsic tumor suppression mechanisms including cell senescence and apoptosis, which further augments the growth of a tumor.
  • Cancer cells also upregulate other CDK and cyclins and decrease suppressive mechanisms such as intrinsic CDK inhibitors and tumor suppressor proteins. The overall effect of this type of cell cycle dysregulation is malignant cell proliferation and the development of cancer (Clinical Breast Cancer, 2016, 1526-8209).
  • CDK inhibitors have been reported (such as in WO2011101409 and WO2011101417) or clinically developed. Flavopiridol and R-Roscovitine (Seliciclib), were the first generation of pan-CDK inhibitors with anti-tumor activity attributed to down- regulation of CDK9-mediated anti-apoptotic proteins, especially Mcl-1. Recently, a new generation of CDK inhibitors have been developed, advanced to clinical trials, and approved for certain types of cancer.

Description

HETEROCYCLIC COMPOUNDS AS KINASE INHIBITORS
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional Application No. 63/183,537, filed on May 3, 2021, the content of which is incorporated herein by reference in its entirety.
FIELD OF INVENTION
[0002] This disclosure relates generally to therapeutics which play a crucial role in the control of the cell cycle and more particularly, compounds that inhibit cyclin-dependent kinases (CDK). The disclosure also provides pharmaceutically acceptable compositions comprising compounds of the present disclosure and methods of using said compositions in the treatment of diseases associated with these pathways.
BACKGROUND
[0003] The cell cycle is a period between the successive divisions of a cell. During this period, the contents of the cell must be accurately replicated. The processes that permit the cell to divide are very precisely controlled by a multitude of enzymatic reactions amongst which the protein kinase-triggered protein phosphorylation plays a major role. In eukaryotes, there are four main stages/phases of cell cycle namely the Gap-1 (G1) phase, Synthesis (S) phase, Gap-2 (G2) and Mitosis (M) phases. An extended phase of Gap-1 phase is coined as Gap-0 (G0) phase or Resting phase (Cancers 2014, 6, 2224-2242).
[0004] Uncontrolled proliferation is the hallmark of cancer and other proliferative disorders and abnormal cell cycle regulation is, therefore, common in these diseases. Cyclin- dependent kinases (CDK) constitute a heterodimeric family of serine/threonine protein kinases involved in cell cycle and transcription. They include two main groups: cell cycle CDK and transcriptional CDK. The functionality of CDK depends on specific interactions with regulatory proteins named cyclins which form heterodimeric complexes with their partners. These complexes are important regulators of the cellular processes, especially in the cell cycle progression.
[0005] The human proteome contains 20 CDK along with 29 cyclins. CDK1, CDK2, CDK4 and CDK6 are generally considered cell cycle CDK, whereas CDK7, CDK8, CDK9 and CDK11 are mainly involved in transcription regulation (Genome Biol 2014; 15(6): 122, Nat Cell Biol 2009; 11(11): 1275-6). CDK5 is the prototype of atypical CDK: it is activated by the non-cyclin proteins p35 (or Cdk5Rl) and p39 (or Cdk5R2) and has unique post-mitotic functions in neuronal biology, angiogenesis and cell differentiation. Proliferative signals induce the transition from the GO or G1 phases into S phase through the activation of the structurally related CDK4 and CDK6 [Development, 2013;140 (15):3079-93, Biochem Pharmacol 2012;84(8):985-93, Nature 2014;510(7505):393-6]. The binding of cyclin D to CDK4 and to CDK6 promotes the phosphorylation of the transcriptional repressor retinoblastoma protein (RB1).
[0006] CDK hyperactivity is often observed in cancer, reflecting their prominent role in cell cycle and transcription regulation. In cancer cells, the process of cell division becomes unregulated, resulting in uncontrolled growth that leads to the development of a tumor. A number of mechanisms contribute to the dysregulation of the cell cycle in malignant cells, including the amplification and hyperactivity of CDK4/6, or their genomic instability, which might cause CDK4/6 to become oncogenic drivers of cell replication. Usurping these mechanisms, cancer cells can continue to replicate by triggering the G1 to S phase transition. This process appears to be facilitated by a shortening of the G1 phase. In a cancer cell, CDK4/6 antagonizes intrinsic tumor suppression mechanisms including cell senescence and apoptosis, which further augments the growth of a tumor. Cancer cells also upregulate other CDK and cyclins and decrease suppressive mechanisms such as intrinsic CDK inhibitors and tumor suppressor proteins. The overall effect of this type of cell cycle dysregulation is malignant cell proliferation and the development of cancer (Clinical Breast Cancer, 2016, 1526-8209).
[0007] Several CDK inhibitors have been reported (such as in WO2011101409 and WO2011101417) or clinically developed. Flavopiridol and R-Roscovitine (Seliciclib), were the first generation of pan-CDK inhibitors with anti-tumor activity attributed to down- regulation of CDK9-mediated anti-apoptotic proteins, especially Mcl-1. Recently, a new generation of CDK inhibitors have been developed, advanced to clinical trials, and approved for certain types of cancer. Dinaciclib, a selective inhibitor of CDK1, CDK2, CDK5, and CDK9, was directed towards refractory chronic lymphocytic leukemia while palbociclib was tested against advanced estrogen receptor (ER)-positive breast cancer as a selective inhibitor of CDK4 and CDK6. The development of more selective second and third generation CDK inhibitors, including specific CDK4/6 inhibitors, has led to a renewed enthusiasm for manipulating the cyclin D1-CDK4/6 axis in cancer treatment. There are three FDA-approved CDK4/6 inhibitors presently: Palbociclib, Ribociclib and Abemaciclib. [0008] The development of therapies, including monotherapies, for treatment of proliferative disorders using a therapeutic targeted generically at CDK, or specifically at dual inhibition of CDK4 and CDK6, is therefore potentially highly desirable.
[0009] There is still a need for new CDK4/6 inhibitors. Compounds for the treatment of hyper-proliferative diseases preferably have at least one advantageous property selected from selectivity, potency, stability, pharmacodynamic properties and safety profile. In this regard, a novel class of CDK4/6 inhibitors is provided herein.

[0015] As used in the present specification, the following words, phrases and symbols are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise. [0016] The term “about” refers to a variation of ±1%, ±3%, ±5%, or +10% of the value specified. For example, “about 50” can in some embodiments includes a range of from 45 to 55. For integer ranges, the term “about” can include one or two integers greater than and/or less than a recited integer at each end of the range. Unless indicated otherwise herein, the term “about” is intended to include values, e.g., weight percentages, proximate to the recited range that are equivalent in terms of the functionality of the individual ingredient, the composition, or the embodiment. Also, the singular forms “a” and “the” include plural references unless the context clearly dictates otherwise. Thus, e.g., reference to “the compound” includes a plurality of such compounds and includes reference to one or more compounds and equivalents thereof known to those skilled in the art.

In one variation, the aryl group contains from 6 to 14 annular carbon atoms (“C6-C14 aryl”),. Examples of aryl groups include, but are not limited to, phenyl, naphthyl, and anthryl. Aryl, however, does not encompass or overlap in any way with heteroaryl defined below. If one or more aryl groups are fused with a heteroaryl, the resulting ring system is heteroaryl. If one or more aryl groups are fused with a heterocyclyl, the resulting ring system is heterocyclyl.
[0024] “Carbonyl” refers to the group C=O. [0025] “Cycloalkyl” refers to a saturated or partially unsaturated cyclic alkyl group having a single ring or multiple rings including fused, bridged and spiro ring systems.

A heterocyclyl may be a single ring or multiple rings wherein the multiple rings may be fused, bridged or spiro, and may comprise one or more (e.g., 1 to 3) oxo (=0) or N-oxide (-O-) moieties. Any non- aromatic ring containing at least one heteroatom is considered a heterocyclyl, regardless of the attachment (i.e., can be bound through a carbon atom or a heteroatom). Further, the term heterocyclyl is intended to encompass any non-aromatic ring containing at least one heteroatom, which ring may be fused to an aryl or heteroaryl ring, regardless of the attachment to the remainder of the molecule. As used herein, heterocyclyl has 2 to 20 ring carbon atoms, 2 to 12 ring carbon atoms, 2 to 10 ring carbon atoms, 2 to 8 ring carbon atoms, 3 to 12 ring carbon atoms, 3 to 8 ring carbon atoms, or 3 to 6 ring carbon atoms; and 1 to 5 ring heteroatoms, 1 to 4 ring heteroatoms, 1 to 3 ring heteroatoms, 1 to 2 ring heteroatoms, or 1 ring heteroatom independently selected from nitrogen, sulfur or oxygen.

[0031] As used herein “CDK” refers to one or more cyclin-dependent kinases. CDK4/6 refers to both CDK4 and CDK6. Thus, inhibitors of CDK4/6 inhibit both CDK4 and CDK6.
[0032] A “pharmaceutically acceptable carrier” refers to an ingredient in a pharmaceutical formulation, other than an active ingredient, which is nontoxic to a subject. A pharmaceutically acceptable carrier includes, but is not limited to, a buffer, excipient, stabilizer, or preservative.
[0033] As used herein, “treatment” or “treating” is an approach for obtaining beneficial or desired results including clinical results. For example, beneficial or desired results include, but are not limited to, one or more of the following: decreasing symptoms resulting from the disease, increasing the quality of life of those suffering from the disease, decreasing the dose of other medications required to treat the disease, delaying the progression of the disease, and/or prolonging survival of individuals. In reference to cancers or other unwanted cell proliferation, beneficial or desired results include shrinking a tumor (reducing tumor size); decreasing the growth rate of the tumor (such as to suppress tumor growth); reducing the number of cancer cells; inhibiting, retarding or slowing to some extent and preferably stopping cancer cell infiltration into peripheral organs; inhibiting (slowing to some extent and preferably stopping) tumor metastasis; inhibiting tumor growth; preventing or delaying occurrence and/or recurrence of tumor; and/or relieving to some extent one or more of the symptoms associated with the cancer. In some embodiments, beneficial or desired results include preventing or delaying occurrence and/or recurrence, such as of unwanted cell proliferation.
[0034] As used herein, “delaying development of a disease” means to defer, hinder, slow, retard, stabilize, and/or postpone development of the disease (such as cancer). This delay can be of varying lengths of time, depending on the history of the disease and/or individual being treated. As is evident to one skilled in the art, a sufficient or significant delay can, in effect, encompass prevention, in that the individual does not develop the disease. For example, a late stage cancer, such as development of metastasis, may be delayed.
[0035] As used herein, an “effective dosage” or “effective amount” of compound or salt thereof or pharmaceutical composition is an amount sufficient to effect beneficial or desired results. For prophylactic use, beneficial or desired results include results such as eliminating or reducing the risk, lessening the severity of, or delaying the onset of the disease, including biochemical, histological and/or behavioral symptoms of the disease, its complications and intermediate pathological phenotypes presenting during development of the disease. For therapeutic use, beneficial or desired results include ameliorating, palliating, lessening, delaying or decreasing one or more symptoms resulting from the disease, increasing the quality of life of those suffering from the disease, decreasing the dose of other medications required to treat the disease, enhancing effect of another medication such as via targeting, delaying the progression of the disease, and/or prolonging survival. In reference to cancers or other unwanted cell proliferation, an effective amount comprises an amount sufficient to cause a tumor to shrink and/or to decrease the growth rate of the tumor (such as to suppress tumor growth) or to prevent or delay other unwanted cell proliferation. In some embodiments, an effective amount is an amount sufficient to delay development. In some embodiments, an effective amount is an amount sufficient to prevent or delay occurrence and/or recurrence. An effective amount can be administered in one or more administrations, in the case of cancer, the effective amount of the drug or composition may: (i) reduce the number of cancer cells; (ii) reduce tumor size; (iii) inhibit, retard, slow to some extent and preferably stop cancer cell infiltration into peripheral organs; (iv) inhibit (i.e., slow to some extent and preferably stop) tumor metastasis; (v) inhibit tumor growth; (vi) prevent or delay occurrence and/or recurrence of tumor; and/or (vii) relieve to some extent one or more of the symptoms associated with the cancer. An effective dosage can be administered in one or more administrations. For purposes of this disclosure, an effective dosage of compound or a stereoisomer or tautomer thereof, or a pharmaceutically acceptable salt of any of the foregoing, or pharmaceutical composition is an amount sufficient to accomplish prophylactic or therapeutic treatment either directly or indirectly. It is intended and understood that an effective dosage of a compound or salt thereof, or pharmaceutical composition may or may not be achieved in conjunction with another drug, compound, or pharmaceutical composition. Thus, an “effective dosage” may be considered in the context of administering one or more therapeutic agents, and a single agent may be considered to be given in an effective amount if, in conjunction with one or more other agents, a desirable result may be or is achieved.
[0036] As used herein, the term “individual” is a mammal, including humans. An individual includes, but is not limited to, human, bovine, horse, feline, canine, rodent, or primate. In some embodiments, the individual is human. The individual (such as a human) may have advanced disease or lesser extent of disease, such as low tumor burden. In some embodiments, the individual is at an early stage of a proliferative disease (such as cancer). In some embodiments, the individual is at an advanced stage of a proliferative disease (such as an advanced cancer).
[0037] As used herein, by “pharmaceutically acceptable” or “pharmacologically acceptable” is meant a material that is not biologically or otherwise undesirable, e.g., the material may be incorporated into a pharmaceutical composition administered to a patient without causing any significant undesirable biological effects or interacting in a deleterious manner with any of the other components of the composition in which it is contained. Pharmaceutically acceptable carriers or excipients have preferably met the required standards of toxicological and manufacturing testing and/or are included on the Inactive Ingredient Guide prepared by the U.S. Food and Drug administration.
[0038] “Pharmaceutically acceptable salts” are those salts which retain at least some of the biological activity of the free (non- salt) compound and which can be administered as drugs or pharmaceuticals to an individual. Such salts, for example, include: (1) acid addition salts, formed with inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like; or formed with organic acids such as acetic acid, oxalic acid, propionic acid, succinic acid, maleic acid, tartaric acid and the like; (2) salts formed when an acidic proton present in the parent compound either is replaced by a metal ion, e.g., an alkali metal ion, an alkaline earth ion, or an aluminum ion; or coordinates with an organic base. Acceptable organic bases include ethanolamine, diethanolamine, triethanolamine and the like. Acceptable inorganic bases include aluminum hydroxide, calcium hydroxide, potassium hydroxide, sodium carbonate, sodium hydroxide, and the like. Further examples of pharmaceutically acceptable salts include those listed in Berge et al., Pharmaceutical Salts, J. Pharm. Sci. 1977 Jan;66(l):l-19. Pharmaceutically acceptable salts can be prepared in situ in the manufacturing process, or by separately reacting a purified compound of the disclosure in its free acid or base form with a suitable organic or inorganic base or acid, respectively, and isolating the salt thus formed during subsequent purification.
[0039] The term “excipient” as used herein means an inert or inactive substance that may be used in the production of a drug or pharmaceutical, such as a tablet containing a compound of the disclosure as an active ingredient. Various substances may be embraced by the term excipient, including without limitation any substance used as a binder, disintegrant, coating, compression/encapsulation aid, cream or lotion, lubricant, solutions for parenteral administration, materials for chewable tablets, sweetener or flavoring, suspending/gelling agent, or wet granulation agent. Binders include, e.g., carbomers, povidone, xanthan gum, etc.; coatings include, e.g., cellulose acetate phthalate, ethylcellulose, gellan gum, maltodextrin, enteric coatings, etc.; compression/encapsulation aids include, e.g., calcium carbonate, dextrose, fmctose dc (dc=“directly compressible”), honey dc, lactose (anhydrate or monohydrate; optionally in combination with aspartame, cellulose, or microcrystalline cellulose), starch dc, sucrose, etc.; disintegrants include, e.g., croscarmellose sodium, gellan gum, sodium starch glycolate, etc.; creams or lotions include, e.g., maltodextrin, carrageenans, etc.; lubricants include, e.g., magnesium stearate, stearic acid, sodium stearyl fumarate, etc.; materials for chewable tablets include, e.g., dextrose, fructose dc, lactose (monohydrate, optionally in combination with aspartame or cellulose), etc.; suspending/gelling agents include, e.g., carrageenan, sodium starch glycolate, xanthan gum, etc.; sweeteners include, e.g., aspartame, dextrose, fructose dc, sorbitol, sucrose dc, etc.; and wet granulation agents include, e.g., calcium carbonate, maltodextrin, microcrystalline cellulose, etc.

[0169] IC50 values of compounds against the PI3Kδ kinase are determined by an assay performed by Reaction Biology Corporation (Malvern, PA). Briefly, this assay is conducted in buffer (Tris-HCl 40 mM (pH7.5), Orthovanadate 3 mM, MgCl220 mM, DTT 2 mM, CHAPS 0.05%, DMSO 1%). PI3Kδ kinase is added to the reaction solution and mixed gently. The test compounds in 100% DMSO (at specific solutions) are mixed with the kinase reaction mixture to achieve the final compounds at pre-defined concentrations (e.g., range - 0.5 nM to 100 mM) by Acoustic technology (Echo550; nanoliter range). After incubating for 10 min at room temp, ATP is added into the reaction mixture to initiate the reaction followed by a 30-min incubation at 30°C. After quenching the reaction with ADP-Glo reagent, the plates are incubated for 40 min. The Detection Mixture is added, and the plate is incubated for an additional 30 min. At the end of incubation, luminescence is measured. For data analysis, the luminescence is converted into mM ADP production based on ADP standard curves. The nonlinear regression to obtain the standard curve and IC50 values is performed using GraphPad Prism (GraphPad Software, Inc., San Diego, CA).
[0170] IC50 values of compounds against CDK12 (cyclin K) are determined by KinaseProfiler™ radiometric protein kinase assay at Eurofins Pharma Discovery (Dundee, UK). Compounds are prepared to 50x final assay concentration in 100% DMSO. This working stock of the compound is added to the assay well as the first component in each reaction. CDK12/Cyclin K is diluted in buffer (20 mM TRIS, 0.2 mM EDTA, 0.1% b- mercaptoethanol, 0.01% Brij-35, 5% glycerol, 1 mg/ml BSA) prior to addition to the reaction mix. CDK12/Cyclin K is incubated with 20 mM Tris/HCl pH 8.5, 0.2 mM EDTA, 300 μM RSRSRSRSRSRSRSR, 10 mM Magnesium acetate and [γ-33R-ATR] (specific activity and concentration as required). The reaction is initiated by the addition of the Mg/ ATP mix. After incubation for 120 minutes at room temperature, the reaction is stopped by the addition of phosphoric acid to a concentration of 0.5%. 10 pi of the stopped reaction is spotted onto a P30 filtermat and washed four times for 4 minutes in 0.425% phosphoric acid and once in methanol prior to drying and scintillation counting. Results are calculated as a percentage of the mean kinase activity in positive control samples. Data are fitted in XLfit for determination of IC50 values.

[0174] The effects of test compounds are studied in additional cell lines of various histotypes, such as A549 lung adenocarcinoma, HCT-116 colorectal carcinoma, ZR-75-30 breast ductal carcinoma, Hs-578T breast epithelia carcinoma and BT-549 breast ductal carcinoma cells. The cancer cells are harvested during the logarithmic growth period and counted. Cell concentrations are adjusted to the appropriate number with suitable medium, and 90 μL cell suspensions are added to 96-well plates. After cells are seeded, the plates are shaken gently to distribute cells evenly and incubated at 37 °C, 5% CO2 on day 1. Cells are treated with test compounds at typically 7-9 concentrations within a desired concentration range (e.g. 1.5 nM - 10 μM) on day 2 by series diluting the test compound stock solution (10 mM in DMSO) with culture medium. Cell viability is assessed by Cell Titer-Glo® as recommended by Promega (Cat. No.: G7572, Promega) typically 48-144H post-treatment, with a medium change as necessary. Cell viability data are plotted using GraphPad Prism (GraphPad Software, Inc., San Diego, CA). In addition, a nonlinear regression model with a sigmoidal dose response and variable slope within GraphPad Prism is used to calculate the IC50 value of individual test compounds.
[0175] Additional test compounds are studied in the same and/or other cancer cell lines using similar proliferation methods with possible variations in cell seeding densities and/or incubation durations. The cell cycle phase distribution post treatment of test compounds is studied using flow cytometer using DAPI staining. Cellular senescence is evaluated after continuously treating cells for a long time (e.g., 14 days) followed by staining cells lines for Senescence associated-β-galactosidase (SAβGAL).
