Description

[0001] 20443-0830WO1 / INCY0487-WO1 PATENT Bicyclic DGK Inhibitors TECHNICAL FIELD The present invention provides bicyclic compounds that modulate the activity of diacylglycerol kinase (DGK) and are useful in the treatment of diseases related to diacylglycerol kinase, including cancer. BACKGROUND Diacylglycerol kinases (DGKs) are a family of enzymes that regulate many biological processes, including cellular proliferation, migration, immunity and pathogenesis of diseases such as cancer. In mammalian systems, there are ten DGK family members classified into five subtypes based on shared common domains (Sakane F. et al., Int. J. Mol. Sci., 2020.21: p6794-6829). The diverse and specific cellular function of individual DGK isoforms is regulated through their tissue restricted expression, localization within cells and interactions with regulatory proteins (Joshi, R.P. and Koretzky, G.A., Int. J. Mol. Sci., 2013.14: p6649-6673). In T lymphocytes, DGKα and ζ are the dominant DGK isoforms expressed (Krishna, S. and Zhong, X.-P., Front Immunol., 2013.4:178). Specifically, in response to T cell receptor (TCR) activation, phospholipase Cγ1 (PLC ^1) hydrolyzes membrane phospholipid PIP2 to produce diacylglycerol (DAG) (Krishna, S. and Zhong, X.-P., Front Immunol., 2013.4:178; Riese, M.J. et al., Front Cell Dev Biol., 2016.4:108). In turn, DAG functions as a second messenger to recruit RasGRP1 and PKCƟ to the cell membrane and thereby initiates multiple downstream signaling events resulting in T cell activation. To prevent hyperactivation of T cells, DGKα and ζ tightly regulate the levels of intracellular DAG by phosphorylating DAG to produce phosphatidic acid (PA). Both mouse and human cell line genetic studies support the important regulatory role of DGKα and ζ in T cell activation. Knockout or depletion of DGKα and ζ has been reported to enhance T cell activation, cytokine production and proliferation. Furthermore, knockout of both DGKα and ζ show even greater T- cell activation over individual knockouts, indicating a non-redundant role of these two isoforms (Riese, M.J. et al., Cancer Res., 2013.73:p3566-3577; Jung, I.-Y. et al., Cancer Res., 2018.78: p4692-4703). Thus, DGKα and ζ, by regulating cellular DAG 20443-0830WO1 / INCY0487-WO1 PATENT levels link lipid metabolism and intracellular signaling cascades and function as key regulators of T cell activation. Cytotoxic T lymphocytes (CTLs) are a major component of the adaptive immune system that recognize and kill cells with bacterial or viral infections, or cells displaying abnormal proteins, such as tumor antigens. However, cancer cells can evolve to utilize multiple mechanisms that mimic peripheral immune tolerance to avoid immune surveillance and killing by CTLs. Such mechanisms include downregulation of antigen presentation, suppression of T cell function through increased expression of inhibitory molecules, as well as increased production of immunosuppressive proteins in the tumor microenvironment (Speiser, D.E. et al., Nat. Rev. Immunol., 2016.16: p.599-611, Gonzalez H. et al., Genes & Dev., 2018. 32:p1267-1284). Immune checkpoint therapy (ICT) by blocking inhibitory molecules such as PD(L)-1 and CTLA4, can restore T cell activity and have been clinically useful in treating many different types of cancers. However, only subsets of patients respond to ICT due to primary or acquired resistance (Sharma, P. et al., Cell.2017. 168: p707-723). Thus, despite the significant recent clinical successes of immunotherapies to treat cancer, resistance remains a challenge (Sharma, P., et al., Cancer Discov., 2021.11: p838-857). Overexpression of DGKα and ζ has been observed in tumor infiltrating lymphocytes (TILs) from human tumors and proposed to suppress T cell function.Importanly, significant immune-mediated antitumor activity has been shown in DGKα and DGKζ deficient mouse models (Merida, I. et al., Adv. Biol. Regul., 2017.63:p22-31, Prinz, P.U. et al., J. Immunol., 2012.188:p5990-6000). Furthermore, DGKα and DGKζ deficient T cells are resistant to several immunosuppressive factors within the tumor microenvironment such as TGFβ, PGE2 and adenosine, and to other T cell inhibitory pathways such as PD(L)-1 mediated immune suppression (Riese, M.J. et al., Cancer Res., 2013.73:p3566-77; Jung, I.-Y. et al. (2018) Cancer Res., 2018.78:p4692-4703;, Arranz-Nicolas, J. et al., Cancer Immunol. Immunother., 2018.67:p965-980; Riese, M.J. et al., Front. Cell Dev. Biol., 2016.4:108). Thus DGKα and DGKζ are attractive targets as immunotherapies alone or in combination with current ICT therapies such as PD(L)-1 and CTLA4. By targeting T cell lipid metabolism, DGKα and DGKζ inhibition can potentially restore 20443-0830WO1 / INCY0487-WO1 PATENT antitumor immunity in subsets of patient who have primary or acquired immune resistance and are consequently refractory to current ICTs. In addition to its function in T lymphocytes, DGKα and DGKζ, by regulating DAG level in cancer cells, have also been reported to directly contribute to cancer proliferation, migration, invasion and survival. Thus, DGK inhibition may have direct antitumor effect by interfering with tumor intrinsic oncogenic survival pathways (Cooke, M. and Kaznietz, M.G., Sci. Signal., 2022.15:eabo0264). Compounds in this application may have selective activities towards one or both DGKα and DGKζ. These DGK inhibitors alone or in combination with other therapeutic agent(s) can be used in treatment of cancer.

As used herein, the term “independently selected from” means that each occurrence of a variable or substituent (e.g., each RM) , are independently selected at each occurrence from the applicable list. The compounds described herein can be asymmetric (e.g., having one or more stereocenters). All stereoisomers, such as enantiomers and diastereomers, are intended unless otherwise indicated. Compounds of the present disclosure that contain asymmetrically substituted carbon atoms can be isolated in optically active or racemic forms. Methods on how to prepare optically active forms from optically inactive starting materials are known in the art, such as by resolution of racemic mixtures or by stereoselective synthesis. Many geometric isomers of olefins, C=N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present disclosure are described and may be isolated as a mixture of isomers or as separated isomeric forms. In some embodiments, the 20443-0830WO1 / INCY0487-WO1 PATENT compound has the (R)-configuration. In some embodiments, the compound has the (S)-configuration. The Formulas (e.g., Formula I, Formula II, etc.) provided herein include stereoisomers of the compounds. Resolution of racemic mixtures of compounds can be carried out by any of numerous methods known in the art. An example method includes fractional recrystallizaion using a chiral resolving acid which is an optically active, salt-forming organic acid. Suitable resolving agents for fractional recrystallization methods are, for example, optically active acids, such as the D and L forms of tartaric acid, diacetyltartaric acid, dibenzoyltartaric acid, mandelic acid, malic acid, lactic acid or the various optically active camphorsulfonic acids such as β-camphorsulfonic acid. Other resolving agents suitable for fractional crystallization methods include stereoisomerically pure forms of α-methylbenzylamine (e.g., S and R forms, or diastereomerically pure forms), 2-phenylglycinol, norephedrine, ephedrine, N- methylephedrine, cyclohexylethylamine, 1,2-diaminocyclohexane, and the like. Resolution of racemic mixtures can also be carried out by elution on a column packed with an optically active resolving agent (e.g., dinitrobenzoylphenylglycine). Suitable elution solvent composition can be determined by one skilled in the art. Compounds provided herein also include tautomeric forms. Tautomeric forms result from the swapping of a single bond with an adjacent double bond together with the concomitant migration of a proton. Tautomeric forms include prototropic tautomers which are isomeric protonation states having the same empirical formula and total charge. Example prototropic tautomers include ketone – enol pairs, amide - imidic acid pairs, lactam – lactim pairs, enamine – imine pairs, and annular forms where a proton can occupy two or more positions of a heterocyclic system, for example, 1H- and 3H-imidazole, 1H-, 2H- and 4H- 1,2,4-triazole, 1H- and 2H- isoindole, 2-hydroxypyridine and 2-pyridone, and 1H- and 2H-pyrazole. Tautomeric forms can be in equilibrium or sterically locked into one form by appropriate substitution. All compounds, and pharmaceutically acceptable salts thereof, can be found together with other substances such as water and solvents (e.g. hydrates and solvates) or can be isolated. 20443-0830WO1 / INCY0487-WO1 PATENT In some embodiments, preparation of compounds can involve the addition of acids or bases to affect, for example, catalysis of a desired reaction or formation of salt forms such as acid addition salts. In some embodiments, the compounds provided herein, or salts thereof, are substantially isolated. By “substantially isolated” is meant that the compound is at least partially or substantially separated from the environment in which it was formed or detected. Partial separation can include, for example, a composition enriched in the compounds provided herein. Substantial separation can include compositions containing at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, at least about 97%, or at least about 99% by weight of the compounds provided herein, or salt thereof. The term “compound” as used herein is meant to include all stereoisomers, geometric isomers, tautomers, and isotopes of the structures depicted. Compounds herein identified by name or structure as one particular tautomeric form are intended to include other tautomeric forms unless otherwise specified. The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and / or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit / risk ratio. The present application also includes pharmaceutically acceptable salts of the compounds described herein. As used herein, “pharmaceutically acceptable salts” refers to derivatives of the disclosed compounds wherein the parent compound is modified by converting an existing acid or base moiety to its salt form. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts of the present disclosure include the conventional non-toxic salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. The pharmaceutically acceptable salts of the present disclosure can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms 20443-0830WO1 / INCY0487-WO1 PATENT of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, non-aqueous media like ether, ethyl acetate, alcohols (e.g., methanol, ethanol, iso-propanol, or butanol) or acetonitrile (ACN) are preferred. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, p.1418 and Journal of Pharmaceutical Science, 66, 2 (1977), each of which is incorporated herein by reference in its entirety. Synthesis As will be appreciated by those skilled in the art, the compounds provided herein, including salts and stereoisomers thereof, can be prepared using known organic synthesis techniques and can be synthesized according to any of numerous possible synthetic routes. The schemes below provide general guidance in connection with preparing the compounds of the invention. One skilled in the art would understand that the preparations shown in the schemes can be modified or optimized using general knowledge of organic chemistry to prepare various compounds of the invention. Compounds of Formula 1-8 can be synthesized, for example, according to the process shown in Scheme 1. As depicted in Scheme 1, protection of amino compounds of Formula 1-1 under appropriate conditions (e.g., including, but not limited to, reductive amination reactions with an appropriate aldehyde, such as benzaldehyde, in the presence of a reducing agent, such as sodium triacetoxyborohydride) generates compounds of Formula 1-2. Compounds of Formula 1-1 are commercially available, or can be readily synthesized according to methods known by persons skilled in the art. Amide coupling reactions of compounds of Formula 1-2 with compounds of Formula 1-3 under suitable conditions (e.g., in the presence of a coupling reagent, such as HATU, and a base, such as N-ethyl-N- isopropylpropan-2-amine, in an appropriate solvent, such as affords compounds of Formula 1-4. Deprotection of the tert-butoxycarbonyl group in compounds of Formula 1-4 under appropriate conditions (e.g., using an acid, such as trifluoroacetic acid), followed by intramolecular cyclization under appropriate conditions (e.g., using a suitable solvent, such as MeOH) provides compounds of 20443-0830WO1 / INCY0487-WO1 PATENT Formula 1-5. Reduction of compounds of Formula 1-5 under suitable conditions (e.g., using a reducing agent, such as borane, in a suitable solvent, such as THF) generates compounds of Formula 1-6. Protection of compounds of Formula 1-6 under appropriate conditions (e.g., via reaction with di-tert-butyl dicarbonate in the presence of a base, such as N-ethyl-N-isopropylpropan-2-amine) provides compounds of Formula 1-7. Selective deprotection of PG in compounds of Formula 1-7 (e.g., where PG is a protecting group such as benzyl) under appropriate conditions (e.g., using an appropriate catalyst, such as palladium on carbon, in the presence of hydrogen gas), affords compounds of Formula 1-8. Scheme 1. Compounds of Formula 2-4 can be prepared, for example, using the process illustrated in Scheme 2. In the process depicted in Scheme 2, nucleophilic substitution reactions between compounds of Formula 2-1 and compounds of Formula 2-2 under appropriate conditions (e.g., in the presence of a base, such as N-ethyl-N- isopropylpropan-2-amine, in an appropriate solvent, such as CH3CN) generates compounds of Formula 2-3. Removal of an appropriate protecting group (e.g., wherein PG is a group such as tert-butoxycarbonyl) from compounds of Formula 2-3 under appropriate conditions (e.g., in the presence of an acid, such as HCl or trifluoroacetic acid, in a suitable solvent, such as tetrahydrofuran, 1,4-dioxane, or CH2Cl2) affords compounds of Formula 2-4. 20443-0830WO1 / INCY0487-WO1 PATENT Scheme 2. Alternatively, compounds of Formula 2-4 can be prepared, for example, using the process illustrated in Scheme 3. In the process depicted in Scheme 3, amide coupling reactions of compounds of Formula 3-1 with compounds of Formula 3-2 affords compounds of Formula 3-3. Subjection of compounds of Formula 3-3 to reductive alkylation conditions (e.g., through the use of an appropriate transition metal catalyst, such as IrCl(CO)(PPh3)2, in the presence of a silane, such as 1,1,3,3- tetramethyldisiloxane, followed by addition of a suitable organometallic reagent, such as a Grignard reagent) affords compounds of Formula 2-3. Removal of an appropriate protecting group (e.g., wherein PG is a group such as tert-butoxycarbonyl) from compounds of Formula 2-3 under appropriate conditions (e.g., in the presence of an acid, such as HCl or trifluoroacetic acid, in a suitable solvent, such as tetrahydrofuran, 1,4-dioxane, or CH2Cl2) affords compounds of Formula 2-4. For earlier introduction of the Cy1substituent, amide coupling of compounds of Formula 3-1 with compounds of Formula 3-4 affords compounds of Formula 3-5. Subsequent installation of the R1substituent can be achieved by subjection of compounds of Formula 3-5 to reductive alkylation conditions to furnish intermediate compounds of Formula 2-3.

[0002] 20443-0830WO1 / INCY0487-WO1 PATENT Scheme 3. Compounds of Formula 4-4 can be synthesized using the process shown in Scheme 4. As depicted in Scheme 4, a number of methods (e.g., nucleophilic aromatic substitution or a suitable cross-coupling reaction) can be used to access compounds of the general Formula 4-2. For example, compounds of Formula 4-1 (i.e., each Hal can independently be F, Cl, Br, or I) can be reacted with an appropriate amine nucleophile 2-4 in an appropriate solvent (e.g., 1-butanol) at an appropriate temperature (e.g., ranging from room temperature to 200 °C) for a suitable time (e.g., ranging from several minutes to several days) to generate compounds of Formula 4-2. Alternatively, transition metal (e.g., Pd, Cu, Ni) catalyzed reactions (including, but not limited to, Buchwald, Ullman, Suzuki, Stille, Negishi couplings) of compounds 4- 1 and appropriate coupling partners (e.g., primary or secondary amines, nitrogen heterocycles, or heteroaryl boronic acids / esters, trialkyl tin, or zinc reagents) affords compounds of Formula 4-2. Compounds of Formula 4-1 are commercially available, or can be readily synthesized according to methods known by persons skilled in the art. Nitrogen functionalization of compounds of Formula 4-2 using a number of methods (e.g., including, but not limited to, nucleophilic substitution or Mitsunobu reactions) provides access into compounds of Formula 4-4. For example, compounds of Formula 4-2 can be reacted with an appropriate electrophile (e.g., (S)- 20443-0830WO1 / INCY0487-WO1 PATENT (tetrahydrofuran-2-yl)methyl methanesulfonate) in the presence of a suitable base (e.g., potassium carbonate) to afford compounds of Formula 4-4. Alternatively, direct functionalization of compounds of Formula 4-1 using a number of methods (e.g., including, but not limited to, nucleophilic substitution or Mitsunobu reactions) provides access into compounds of Formula 4-3. For example, compounds of Formula 4-1 can be reacted with a suitable alcohol (e.g., (S)-(tetrahydrofuran-2-yl)methanol) in the presence of appropriate reagents (e.g., including a phosphine, such as triphenylphosphine, and an azodicarboxylate, such as diisopropyl azodicarboxylate) to furnish compounds of Formula 4-3. Reaction of compounds of Formula 4-3 with amine nucleophiles of Formula 2-4 using a number of methods (e.g., nucleophilic aromatic substitution or a suitable cross-coupling reaction) can be used to access compounds of Formula 4-4. Scheme 4. Compounds of Formula I can be prepared using the process illustrated in Scheme 5. As depicted in Scheme 5, C–O bond forming reactions (e.g., transition metal catalyzed or nucleophilic aromatic substitution) between compounds of Formula 4-4 and an appropriate nucleophile (e.g., potassium hydroxide) under appropriate conditions (e.g., in the presence of a palladium catalyst, such as methanesulfonato(2-(di-t-butylphosphino)-3,6-dimethoxy-2',4',6'-tri-i-propyl-1,1'- 20443-0830WO1 / INCY0487-WO1 PATENT biphenyl)(2'-amino-1,1'-biphenyl-2-yl)palladium(II)) in an appropriate solvent (e.g., a mixture of 1,4-dioxane and water) generates compounds of Formula 5-1. Functionalization of compounds of Formula 5-1 using a number of conditions (e.g., including, but not limited to, electrophilic substitution or transition metal catalyzed reactions) affords compounds of Formula I. For example, alkylation of Formula 5-1 under appropriate conditions (e.g., using an appropriate alkylating agent, such as chloro(chloromethyl)dimethylsilane or methyl iodide, in the presence of a suitable base, such as 1,1,1,3,3,3-hexamethyldisilazane or potassium carbonate) in an appropriate solvent (e.g., CH3CN or DMF) generates compounds of Formula I. Alternatively, transition metal (e.g., Cu) catalyzed cross-coupling reactions (including, but not limited to, Chan-Lam coupling) between compounds of Formula 5-1 and an appropriate coupling partner (e.g., methylboronic acid) affords compounds of Formula I. Scheme 5. The reactions for preparing compounds described herein can be carried out in suitable solvents which can be readily selected by one of skill in the art of organic synthesis. Suitable solvents can be substantially non-reactive with the starting materials (reactants), the intermediates, or products at the temperatures at which the reactions are carried out, (e.g., temperatures which can range from the solvent's freezing temperature to the solvent's boiling temperature). A given reaction can be carried out in one solvent or a mixture of more than one solvent. Depending on the particular reaction step, suitable solvents for a particular reaction step can be selected by the skilled artisan. The expressions, “ambient temperature” or “room temperature” or “rt” as used herein, are understood in the art, and refer generally to a temperature, e.g., a reaction 20443-0830WO1 / INCY0487-WO1 PATENT temperature, that is about the temperature of the room in which the reaction is carried out, for example, a temperature from about 20 ºC to about 30 ºC. Preparation of compounds described herein can involve the protection and deprotection of various chemical groups. The need for protection and deprotection, and the selection of appropriate protecting groups, can be readily determined by one skilled in the art. The chemistry of protecting groups can be found, for example, in T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 3rdEd., Wiley & Sons, Inc., New York (1999). Reactions can be monitored according to any suitable method known in the art. For example, product formation can be monitored by spectroscopic means, such as nuclear magnetic resonance spectroscopy (e.g.,1H or13C), infrared spectroscopy, spectrophotometry (e.g., UV-visible), mass spectrometry, or by chromatographic methods such as high performance liquid chromatography (HPLC), liquid chromatography-mass spectroscopy (LCMS), or thin layer chromatography (TLC). Compounds can be purified by those skilled in the art by a variety of methods, including high performance liquid chromatography (HPLC) and normal phase silica chromatography. Methods of Use The compounds described herein can inhibit the activity of DGK. Compounds that inhibit DGK are useful in providing a means of preventing the growth or inducing apoptosis of cancer cells. Such compounds are also useful in treating cancer cells exhibiting alterations in diacylglyceraol-regulating enzymes and effectors. It is therefore anticipated that the compounds of the disclosure are useful in treating or preventing cancer, such as solid tumors. In certain embodiments, the disclosure provides a method for treating a DGK- related disorder in a patient in need thereof, comprising the step of administering to said patient a compound of the disclosure, or a pharmaceutically acceptable composition thereof. The compounds or salts described herein can be selective. By “selective,” it is meant that the compound binds to or inhibits DGKα or DGKζ with greater affinity or potency, respectively, compared to at least one other DGK isoforms, or kinase, etc. In 20443-0830WO1 / INCY0487-WO1 PATENT some embodiments, selectivity can be at least about 2-fold, 5-fold, 10-fold, at least about 20-fold, at least about 50-fold, at least about 100-fold, at least about 200-fold, at least about 500-fold or at least about 1000-fold. The compounds of the present disclosure can also be dual antagonists (i.e., inhibitors), e.g. inhibit both DGKα and DGKζ kinases. In some embodiments, the compounds of the invention are selective inhibitors of DGKα (e.g., over one or more other DGK isoforms, or kinase, etc.). In some embodiments, the compounds of the invention are selective inhibitors of DGKζ (e.g., over one or more other DGK isoforms, or kinase, etc.). Selectivity can be measured by methods routine in the art. In some embodiments, selectivity can be tested at the KmATP concentration of each enzyme. In some embodiments, the selectivity of compounds of the invention can be determined by cellular assays associated with particular DGK kinase activity. Based on compelling evidence that DGKα and DGKζ negatively regulate signaling pathways downstream of the T cell receptor, developing DGK inhibitors can boost T cell effector function and inhibit tumor progression. DGK inhibitors can be used to treat, alone or in combination with other therapies, renal cell carcinoma, mesothelioma, glioblastoma multiforme, colorectal cancer, melanoma, pancreatic cancer (Chen, S.S. et al., Front. Cell Dev. Biol., 2016.4:130; Gu, J. et al., Oncoimmunol., 2021.10, e1941566; Jung I.-Y. et al., Cancer Res., 2018.78:p4692- 4703; Sitaram, P., et al., Int. J Mol. Sci., 2019.20:p5821-5848; Wesley, E.M., et al., Immunohorizons, 2018.2:p107-118) In addition, DGKα has been shown to enhance esophageal squamous cell carcinoma (ESCC), and human hepatocellular carcinoma (HCC) progression (Chen, J. et al., Oncogene, 2019.38: p2533-2550; Takeishi, K. et al., J. Hepatol., 2012.57:p77- 83), to support colon and breast cancer growth in three-dimensional (3D) culture (Torres-Ayuso, P. et al., Oncotarget, 2014.5:p9710-9726), to enhance mammary carcinoma invasiveness (Rainero, E. et al., PLOS ONE, 2014.9(6): e97144) and promote metastasis of non-small cell lung cancer (NSCLC) (Fu, L. et al., Cancer letters, 2022.532: 215585) whereas DGKζ has been implicated as a potential oncogene in osteosarcoma proliferation (Yu, W. et al., Front. Oncol., 2019.8:655) and contributed to enhanced invasion of human metastatic colon cancer cells (Cai, K. et al., BMC Cancer, 2014.14:208). It has also been reported DGK inhibition has the 20443-0830WO1 / INCY0487-WO1 PATENT potential to reduce immunopathology in X-linked lymphoproliferative disease patient (Velnati, S. et al., Eur. J. Med. Chem., 2019.164: p378-390; Ruffo, E. et al., Sci. Transl. Med.2016.8 (321):321ra7). In some embodiments, the DGK-related disorder is a solid tumor. Example solid tumors include, but are not limited to, breast cancer, colorectal cancer, gastric cancer, and glioblastoma (see e.g., Cooke & Kazanietz, Sci. Signal, 2022, 15, eabo0264:1-26). Example cancers associated with alterations in DAG-regulating enzymes and effector include, but are not limited to, uveal melanoma, myelodysplastic syndrome (MDS), angiosarcoma, nodal peripheral T cell lymphoma, adult T-cell leukemia lymphoma (ATLL), cutaneous T-cell lymphoma (CTCL) / Sezary syndrome, chronic lymphocytic leukemia (CLL), breast cancer, gastric cancer, colorectal cancer, oral squamous cell carcinoma (SCC), esophageal SCC, chronic myeloid leukemia (CML), colon cancer, prostate cancer, hepatocellular carcinoma (HCC), blue nevi, NK / T cell lymphoma, glioma, ovarian cancer, liver cancer, melanoma, heptacarcinoma, ostersarcoma, chordiod glioma, pigmented epithelioid melanocytoma, papillary glioneuronal tumor, fibrous histiocytoma, pituitary tumor, thyroid cancer, head and neck SCC, lung cancer, pediatric T-cell acute lymphoblastic leukemia (T-ALL), endometrial cancer, angiolipoma, salivary gland cancer, acute myeloid leukemia (AML), Epstein-Barr virus-associated (EBV)- associated B cell lymphoma, diffuse large B cell lymphoma (DLBCL), and cervical cancer (see e.g., Cooke & Kazanietz, Sci. Signal, 2022, 15, eabo0264:1-26). In some embodiments, the cancer is selected from lung cancer, bladder cancer, urothelial cancer, esophageal cancer, stomach cancer, mesothelioma, liver cancer, diffuse large B cell lymphoma, kidney cancer, head and neck cancer, cholangiocarcinoma, cervical cancer, endocervical cancer, and melanoma. In some embodiments, the cancer is selected from non-small cell lung cancer (lung squamous cell carcinoma (LUSC), lung adenocarcinoma (LUAD)), bladder urothelial carcinoma, esophageal carcinoma, stomach adenocarcinoma, mesothelioma, liver hepatocellular carcinoma, diffuse large B cell lymphoma (DLBCL), kidney renal clear cell carcinoma, head and neck squamous cell carcinoma, cholangiocarcinoma, cervical squamous cell carcinoma, endocervical adenocarcinoma, and metastatic melanoma. 20443-0830WO1 / INCY0487-WO1 PATENT In some embodiments, the cancer is a myelodysplastic syndrome. As used herein, myelodysplastic syndromes are intended to encompass heterogeneous and clonal hematopoietic disorders that are characterized by ineffective hematopoiesis on one or more of the major myeloid cell lineages. Myelodysplastic syndromes are associated with bone marrow failure, peripheral blood cytopenias, and a propensity to progress to acute myeloid leukemia (AML). Moreover, clonal cytogenetic abnormalities can be detected in about 50% of cases with MDS. In 1997, The World Health Organization (WHO) in conjunction with the Society for Hematopathology (SH) and the European Association of Hematopathology (EAHP) proposed new classifications for hematopoietic neoplasms (Harris, et al., J Clin Oncol 1999;17:3835-3849; Vardiman, et al., Blood 2002;100:2292-2302). For MDS, the WHO utilized not only the morphologic criteria from the French-American-British (FAB) classification but also incorporated available genetic, biologic, and clinical characteristics to define subsets of MDS (Bennett, et al., Br. J. Haematol. 1982;51:189-199). In 2008, the WHO classification of MDS (Table 1) was further refined to allow precise and prognostically relevant subclassification of unilineage dysplasia by incorporating new clinical and scientific information (Vardiman, et al., Blood 2009;114:937-951; Swerdlow, et al., WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues.4th Edition. Lyon France: IARC Press; 2008:88-103; Bunning and Germing, “Myelodysplastic syndromes / neoplasms” in Chapter 5, Swerdlow, et al, eds. WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues. (ed.4th edition): Lyon, France: IARC Press;2008:88-103). Table 1.2008 WHO Classification for De Novo Myelodysplastic Syndrome 20443-0830WO1 / INCY0487-WO1 PATENT In some embodiments, the myelodysplastic syndrome is refractory cytopenia with unilineage dysplasia (RCUD). In some embodiments, the myelodysplastic syndrome is refractory anemia with ring sideroblasts (RARS). In some embodiments, the myelodysplastic syndrome is refractory anemia with ring sideroblasts associated with thrombocytosis (RARS-T). In some embodiments, the myelodysplastic syndrome is refractory cytopenia with multilineage dysplasia. In some embodiments, the myelodysplastic syndrome is refractory anemia with excess blasts-1 (RAEB-1). In some embodiments, the myelodysplastic syndrome is refractory anemia with excess blasts-2 (RAEB-2). In some embodiments, the myelodysplastic syndrome is myelodysplastic syndrome, unclassified (MDS-U). In some embodiments, the myelodysplastic syndrome is myelodysplastic syndrome associated with isolated del(5q). In some embodiments, the myelodysplastic syndrome is refractory to erythropoiesis-stimulating agents. In some embodiments, the compounds of the disclosure can be useful in the treatment of myeloproliferative disorder / myelodysplastic overlap syndrome (MPD / MDS overlap syndrome). 20443-0830WO1 / INCY0487-WO1 PATENT In some embodiments, provided herein is a method of increasing survival or progression-free survival in a patient, comprising administering a compound provided herein to the patient.

In some embodiments, the compounds of the present disclosure, or solid forms or salts thereof, can be used in combination with INCB086550. Pharmaceutical Formulations and Dosage Forms When employed as pharmaceuticals, the compounds of the disclosure can be administered in the form of pharmaceutical compositions. These compositions can be prepared in a manner well known in the pharmaceutical art, and can be administered by a variety of routes, depending upon whether local or systemic treatment is desired and upon the area to be treated. Administration may be topical (including transdermal, epidermal, ophthalmic and to mucous membranes including intranasal, vaginal and rectal delivery), pulmonary (e.g., by inhalation or insufflation of powders or aerosols, including by nebulizer; intratracheal or intranasal), oral, or parenteral. Parenteral administration includes intravenous, intraarterial, subcutaneous, intraperitoneal intramuscular or injection or infusion; or intracranial, e.g., intrathecal or intraventricular, administration. Parenteral administration can be in the form of a single bolus dose, or may be, for example, by a continuous perfusion pump. Pharmaceutical compositions and formulations for topical administration may include transdermal patches, ointments, lotions, creams, gels, drops, suppositories, sprays, liquids and powders. Conventional pharmaceutical carriers, aqueous, powder or oily bases, thickeners and the like may be necessary or desirable. This disclosure also includes pharmaceutical compositions which contain, as the active ingredient, the compound of the disclosure or a pharmaceutically acceptable salt thereof, in combination with one or more pharmaceutically acceptable carriers (excipients). In some embodiments, the composition is suitable for topical administration. In making the compositions of the disclosure, the active ingredient is 20443-0830WO1 / INCY0487-WO1 PATENT typically mixed with an excipient, diluted by an excipient or enclosed within such a carrier in the form of, for example, a capsule, sachet, paper, or other container. When the excipient serves as a diluent, it can be a solid, semi-solid, or liquid material, which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, suppositories, sterile injectable solutions, and sterile packaged powders. In preparing a formulation, the active compound can be milled to provide the appropriate particle size prior to combining with the other ingredients. If the active compound is substantially insoluble, it can be milled to a particle size of less than 200 mesh. If the active compound is substantially water soluble, the particle size can be adjusted by milling to provide a substantially uniform distribution in the formulation, e.g. about 40 mesh. The compounds of the disclosure may be milled using known milling procedures such as wet milling to obtain a particle size appropriate for tablet formation and for other formulation types. Finely divided (nanoparticulate) preparations of the compounds of the disclosure can be prepared by processes known in the art, e.g., see International App. No. WO 2002 / 000196. Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup, and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates; sweetening agents; and flavoring agents. The compositions of the disclosure can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art. The compositions can be formulated in a unit dosage form, each dosage containing from about 5 to about 1000 mg (1 g), more usually about 100 to about 500 20443-0830WO1 / INCY0487-WO1 PATENT mg, of the active ingredient. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient. In some embodiments, the compositions of the disclosure contain from about 5 to about 50 mg of the active ingredient. One having ordinary skill in the art will appreciate that this embodies compositions containing about 5 to about 10, about 10 to about 15, about 15 to about 20, about 20 to about 25, about 25 to about 30, about 30 to about 35, about 35 to about 40, about 40 to about 45, or about 45 to about 50 mg of the active ingredient. In some embodiments, the compositions of the disclosure contain from about 50 to about 500 mg of the active ingredient. One having ordinary skill in the art will appreciate that this embodies compositions containing about 50 to about 100, about 100 to about 150, about 150 to about 200, about 200 to about 250, about 250 to about 300, about 350 to about 400, or about 450 to about 500 mg of the active ingredient. In some embodiments, the compositions of the disclosure contain from about 500 to about 1000 mg of the active ingredient. One having ordinary skill in the art will appreciate that this embodies compositions containing about 500 to about 550, about 550 to about 600, about 600 to about 650, about 650 to about 700, about 700 to about 750, about 750 to about 800, about 800 to about 850, about 850 to about 900, about 900 to about 950, or about 950 to about 1000 mg of the active ingredient. Similar dosages may be used of the compounds described herein in the methods and uses of the disclosure. The active compound can be effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like. For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation 20443-0830WO1 / INCY0487-WO1 PATENT composition containing a homogeneous mixture of a compound of the present disclosure. When referring to these preformulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation is then subdivided into unit dosage forms of the type described above containing from, for example, about 0.1 to about 1000 mg of the active ingredient of the present disclosure. The tablets or pills of the present disclosure can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate. The liquid forms in which the compounds and compositions of the present disclosure can be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles. Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions can be nebulized by use of inert gases. Nebulized solutions may be breathed directly from the nebulizing device or the nebulizing device can be attached to a face mask, tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can be administered orally or nasally from devices which deliver the formulation in an appropriate manner. 20443-0830WO1 / INCY0487-WO1 PATENT Topical formulations can contain one or more conventional carriers. In some embodiments, ointments can contain water and one or more hydrophobic carriers selected from, for example, liquid paraffin, polyoxyethylene alkyl ether, propylene glycol, white Vaseline, and the like. Carrier compositions of creams can be based on water in combination with glycerol and one or more other components, e.g. glycerinemonostearate, PEG-glycerinemonostearate and cetylstearyl alcohol. Gels can be formulated using isopropyl alcohol and water, suitably in combination with other components such as, for example, glycerol, hydroxyethyl cellulose, and the like. In some embodiments, topical formulations contain at least about 0.1, at least about 0.25, at least about 0.5, at least about 1, at least about 2, or at least about 5 wt % of the compound of the disclosure. The topical formulations can be suitably packaged in tubes of, for example, 100 g which are optionally associated with instructions for the treatment of the select indication, e.g., psoriasis or other skin condition. The amount of compound or composition administered to a patient will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration, and the like. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the patient, and the like. The compositions administered to a patient can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11, more preferably from 5 to 9 and most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients, carriers, or stabilizers will result in the formation of pharmaceutical salts. 20443-0830WO1 / INCY0487-WO1 PATENT The therapeutic dosage of a compound of the present disclosure can vary according to, for example, the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound of the disclosure in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the disclosure can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w / v of the compound for parenteral administration. Some typical dose ranges are from about 1 µg / kg to about 1 g / kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg / kg to about 100 mg / kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems. The compositions of the disclosure can further include one or more additional pharmaceutical agents such as a chemotherapeutic, steroid, anti-inflammatory compound, or immunosuppressant, examples of which are listed herein. Labeled Compounds and Assay Methods Another aspect of the present disclosure relates to labeled compounds of the disclosure (radio-labeled, fluorescent-labeled, etc.) that would be useful not only in imaging techniques but also in assays, both in vitro and in vivo, for localizing and quantitating DGK in tissue samples, including human, and for identifying DGK inhibitors by binding of a labeled compound. Substitution of one or more of the atoms of the compounds of the present disclosure can also be useful in generating differentiated ADME (Adsorption, Distribution, Metabolism and Excretion.) Accordingly, the present disclosure includes DGK assays that contain such labeled or substituted compounds. 20443-0830WO1 / INCY0487-WO1 PATENT The present disclosure further includes isotopically-labeled compounds of the disclosure. An “isotopically” or “radio-labeled” compound is a compound of the disclosure where one or more atoms are replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (i.e., naturally occurring). Suitable radionuclides that may be incorporated in compounds of the present disclosure include but are not limited to2H (also written as D for deuterium),3H (also written as T for tritium),11C,13C,14C,13N,15N,15O,17O,18O,18F,35S,36Cl,82Br,75Br,76Br,77Br,123I,124I,125I and131I. For example, one or more hydrogen atoms in a compound of the present disclosure can be replaced by deuterium atoms (e.g., one or more hydrogen atoms of a C1-6alkyl group of Formula I can be optionally substituted with deuterium atoms, such as –CD3being substituted for –CH3). In some embodiments, alkyl groups of the disclosed Formulas (e.g., Formula I) can be perdeuterated. One or more constituent atoms of the compounds presented herein can be replaced or substituted with isotopes of the atoms in natural or non-natural abundance. In some embodiments, the compound includes at least one deuterium atom. For example, one or more hydrogen atoms in a compound presented herein can be replaced or substituted by deuterium (e.g., one or more hydrogen atoms of a C1-6alkyl group can be replaced by deuterium atoms, such as –CD3 being substituted for –CH3). In some embodiments, the compound includes two or more deuterium atoms. In some embodiments, the compound includes 1-2, 1-3, 1-4, 1-5, 1-6, 1-8, 1-10, 1-12, 1-14, 1- 16, 1-18, or 1-20 deuterium atoms. In some embodiments, all of the hydrogen atoms in a compound can be replaced or substituted by deuterium atoms. In some embodiments, each hydrogen atom of the compounds provided herein, such as hydrogen atoms attached to carbon atoms of alkyl, alkenyl, alkynyl, aryl, phenyl, cycloalkyl, heterocycloalkyl, or heteroaryl substituents or -C1-4 alkyl-, alkylene, alkenylene, and alkynylene linking groups, as described herein, is optionally replaced by deuterium atoms. In some embodiments, each hydrogen atom of the compounds provided herein, such as hydrogen atoms to carbon atoms of alkyl, alkenyl, alkynyl, aryl, phenyl, cycloalkyl, heterocycloalkyl, or heteroaryl substituents or -C1-4alkyl-, alkylene, alkenylene, and alkynylene linking groups, as described herein, is replaced 20443-0830WO1 / INCY0487-WO1 PATENT by deuterium atoms (i.e., the alkyl, alkenyl, alkynyl, aryl, phenyl, cycloalkyl, heterocycloalkyl, or heteroaryl substituents, or -C1-4 alkyl-, alkylene, alkenylene, and alkynylene linking groups are perdeuterated). In some embodiments, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 hydrogen atoms, attached to carbon atoms of alkyl, alkenyl, alkynyl, aryl, phenyl, cycloalkyl, heterocycloalkyl, or heteroaryl substituents or -C1-4 alkyl-, alkylene, alkenylene, and alkynylene linking groups, as described herein, are optionally replaced by deuterium atoms. In some embodiments, 1, 2, 3, 4, 5, 6, 7, or 8 hydrogen atoms, attached to carbon atoms of alkyl, alkenyl, alkynyl, aryl, phenyl, cycloalkyl, heterocycloalkyl, or heteroaryl substituents or -C1-4alkyl-, alkylene, alkenylene, and alkynylene linking groups, as described herein, are optionally replaced by deuterium atoms. In some embodiments, the compound provided herein (e.g., the compound of any of Formulas I-VI), or a pharmaceutically acceptable salt thereof, comprises at least one deuterium atom. In some embodiments, the compound provided herein (e.g., the compound of any of Formulas I-VI), or a pharmaceutically acceptable salt thereof, comprises two or more deuterium atoms. In some embodiments, the compound provided herein (e.g., the compound of any of Formulas I-VI), or a pharmaceutically acceptable salt thereof, comprises three or more deuterium atoms. In some embodiments, for a compound provided herein (e.g., the compound of any of Formulas I-VI), or a pharmaceutically acceptable salt thereof, all of the hydrogen atoms are replaced by deuterium atoms (i.e., the compound is “perdeuterated”). Synthetic methods for including isotopes into organic compounds are known in the art (Deuterium Labeling in Organic Chemistry by Alan F. Thomas (New York, N.Y., Appleton-Century-Crofts, 1971; The Renaissance of H / D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and Jochen Zimmermann, Angew. Chem. Int. Ed.2007, 7744-7765; The Organic Chemistry of Isotopic Labelling by James R. Hanson, Royal Society of Chemistry, 2011). Isotopically labeled compounds can be 20443-0830WO1 / INCY0487-WO1 PATENT used in various studies such as NMR spectroscopy, metabolism experiments, and / or assays. Substitution with heavier isotopes, such as deuterium, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. (see e.g., A. Kerekes et. al. J. Med. Chem.2011, 54, 201-210; R. Xu et. al. J. Label Compd. Radiopharm.2015, 58, 308-312). In particular, substitution at one or more metabolism sites may afford one or more of the therapeutic advantages. The radionuclide that is incorporated in the instant radio-labeled compounds will depend on the specific application of that radio-labeled compound. For example, for in vitro DGK labeling and competition assays, compounds that incorporate3H,14C,82Br,125I,131I or35S can be useful. For radio-imaging applications11C,18F,125I,123I,124I,131I,75Br,76Br or77Br can be useful. It is understood that a “radio-labeled” or “labeled compound” is a compound that has incorporated at least one radionuclide. In some embodiments, the radionuclide is selected from the group consisting of3H,14C,125I,35S and82Br. The present disclosure can further include synthetic methods for incorporating radio-isotopes into compounds of the disclosure. Synthetic methods for incorporating radio-isotopes into organic compounds are well known in the art, and an ordinary skill in the art will readily recognize the methods applicable for the compounds of disclosure. A labeled compound of the disclosure can be used in a screening assay to identify / evaluate compounds. For example, a newly synthesized or identified compound (i.e., test compound) which is labeled can be evaluated for its ability to bind DGK by monitoring its concentration variation when contacting with DGK, through tracking of the labeling. For example, a test compound (labeled) can be evaluated for its ability to reduce binding of another compound which is known to bind to DGK (i.e., standard compound). Accordingly, the ability of a test compound to compete with the standard compound for binding to DGK directly correlates to its binding affinity. Conversely, in some other screening assays, the standard compound is labeled and test compounds are unlabeled. Accordingly, the concentration of the 20443-0830WO1 / INCY0487-WO1 PATENT labeled standard compound is monitored in order to evaluate the competition between the standard compound and the test compound, and the relative binding affinity of the test compound is thus ascertained. Kits The present disclosure also includes pharmaceutical kits useful, for example, in the treatment or prevention of DGK-associated diseases or disorders as described herein, which include one or more containers containing a pharmaceutical composition comprising a therapeutically effective amount of a compound of the disclosure. Such kits can further include, if desired, one or more of various conventional pharmaceutical kit components, such as, for example, containers with one or more pharmaceutically acceptable carriers, additional containers, etc., as will be readily apparent to those skilled in the art. Instructions, either as inserts or as labels, indicating quantities of the components to be administered, guidelines for administration, and / or guidelines for mixing the components, can also be included in the kit. The invention will be described in greater detail by way of specific examples. The following examples are offered for illustrative purposes, and are not intended to limit the invention in any manner. Those of skill in the art will readily recognize a variety of non-critical parameters which can be changed or modified to yield essentially the same results.
