Description:
FUSED BICYCLIC COMPOUNDS, COMPOSITIONS AND APPLICATIONS

THEREOF TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates to fused bicyclic compounds that are inhibitors of GPR91 also known as SUCNR1, their stereoisomers, tautomers, prodrugs, polymorphs, solvates, pharmaceutically acceptable salts, and pharmaceutical compositions containing them. These compounds are useful in the treatment, prevention, prophylaxis, management, or adjunct treatment of all medical conditions related to inhibition of GPR91. The disclosure also relates to the process of preparation of the fused bicyclic compounds, and to pharmaceutical compositions containing them.

BACKGROUND OF THE INVENTION

[0002] G-protein coupled receptor, known as GPR91 is expressed in kidney, liver, heart, retinal cells and possibly many other tissues, leading to a wide array of physiological and pathological effects. Succiante, a citric acid cycle intermediate act as an extracellular signaling molecule that binds to and activates GPR91. GPR91 interacts with multiple G-proteins. According to some studies using pertussis toxin, GPR91 can couple either with Gi or G q , triggering different pathways and initiating distinct cellular effects. In HEK293 and MDCK (kidney derived cells), succinate induces intracellular calcium release, inositol triphosphate formation, extracellular- signal-regulated kinases 1/2 (ERK1/2) activation and decrease of cyclic adenosine monophosphate (cAMP) concentration, which are signaling pathways induced by G q or Gi coupling, depending only on succinate concentration (He et al, Nature. 2004 May 13;429(6988): 188-93). In hematopoietic progenitor cells, however, signaling mediated exclusively by Gi/ 0 leads to proliferation due to ERK1/2 activation. In cardiomyocytes, succinate increases rather than decreases cAMP, leading to protein kinase A (PKA) activation, and suggesting that GPR91 coupling to G s is also possible. These distinct intracellular signaling pathways initiated by GPR91 activation indicate that succinate actions as a hormone can indeed be very diverse. Moreover, after triggering the signal transduction cascade, GPR91 is known to undergo internalization. Imaging studies indicated that GPR91 is located specifically on the plasma membrane, and is internalized and then desensitized as a result of ligand stimulation (de Castro Fonseca M et al, Cell Commun Signal. 2016 Jan 12;14:3).

[0003] GPR91 has been described in many cell types, and demonstrated to have a vast array of functions in the human body. In kidney, GPR91 is localized to the proximal tubule, juxtaglomerular apparatus (JGA), distal tubule, glomerulus (likely glomerular endothelial cells) and to the apical membranes of multiple distal segments, including the thick ascending limb, the macula densa (MD), and the principal cells of the cortical and medullary collecting ducts. Succinate is accumulated in extra-cellular spaces under ischemia to act on GPR91 to increase blood pressure, a mechanism to increase local 0 2 supply. Succinate (SA) treatment leads to increase in blood pressure via renin-dependent activation of RAS system and this effect is abolished in GPR91 -/- mice and with angiotensin converting enzyme inhibitor indicating its role in the regulation of blood pressure (He et al, Nature, 2004).

[0004] Human iMoDCs have high expression of GPR91 transcripts and GPR91 expression is induced specifically during the differentiation from monocyte to iMoDC. Succinate induces migration of iMoDCs in U937 cells (U937 is a human macrophage-like cell line which had substantial expression of GPR91 mRNA). Succinate mediates the chemotaxis of human iMoDCs and stimulates the production of inflammatory cytokines. Triggering GPR91 on human iMoDCs with succinate enhances SEA- or tetanus toxoid-induced production of cytokines by human CD4 + T cells in a dose-dependent way. GPR91 mediates the immunomodulatory effects of succinate as GPR91 deletion impairs DC migration and immunity. GPR91 -/- skin grafts elicit weaker allograft rejection responses in vivo than corresponding wild-type grafts indicating its role in immune disorders. (Rubic T et al, Nat immunol. 9(11): 1261-9. 2008).

[0005] GPR91 is expressed in hematopoietic progenitor cell (HPCs). GPR91 mRNA and protein expression were detected in human bone marrow CD34 progenitor cells, as well as in erythroid and megakaryocyte cultures and the erythroleukemic cell line TF-1. Succinate stimulates the proliferation of cultured megakaryocyte and erythroid progenitor cells. Succinate stimulates TF-1 cell proliferation through GPR91 and requires activation of the Erk MAPK pathway. In vivo administration of succinate enhances multilineage blood cell recovery and was found to elevate the levels of hemoglobin, platelets, and neutrophils in a mouse model of chemotherapy- induced myelosuppression. These results suggest that succinate GPR91 signaling is capable of promoting HPC development and its role in Hematopoiesis (Hakak Y et al, J Leukoc Biol. 2009 May;85(5):837-43).

[0006] Succinate levels rise in the ischemic retina of rodents and through GPR91 receptor it mediates vessel growth in normal retinal development and proliferative ischemic retinopathy. GPR91 is expressed in retinal ganglion neurons, retinal pigment epithelium and microglia. Intravitreal succinate injection increased mRNA expression of the proangiogenic factors VEGF, angiopoietin- 1 (Ang-1) and Ang-2, whereas antiangiogenic thrombospondin-1 was repressed. siRNA-mediated knockdown of GPR91 diminished GPR91 mRNA and protein expression and vascular densities and abolished the effects of succinate on the angiogenic factors. siRNA to GPR91 attenuated retinal neovascularization during the ischemic phase of oxygen induced retinopathy (Sapieha et al, Nat Med. 2008 Oct;14 (10): 1067-76). GPR91 knockdown protects against retinal neovascularization in ischemic proliferative retinopathy (Favret et al, Aging , 2013 Jun;5(6):427-44). Exposure to high glucose induces VEGF expression in the RGC-5 cells. GPR91 shRNA inhibits high glucose-induced VEGF release as well as proliferation/ migration of RF/6A cells. GPR91 modulates VEGF release possibly by ERK1/2 and JNK MAPK signaling (Hu J et al, Exp Eye Res. 2013 Apr;109:31-9). All these data suggest role of GPR91 in retinal angiogenesis.

[0007] GPR91 was found to be expressed in quiescent hepatic stellate cells, and its expression was decreased with activation. Succinate levels are increased ~ 14 fold higher during hepatic ischemia and exposure to succinate leads to activation of HSCs (Correa PR et al, Journal of Hepatology 47: 262-269 (2007). C57BL6/J mice fed the MCD diet had elevated succinate levels in their plasma, decreased SDH activity and increased GPR91 and a-SMA expression in isolated HSCs. HSCs cultured in MCD media showed significantly decreased SDH activity and increased succinate concentration and GPR91 and a-smooth muscle actin (a-SMA) expression. Cultured HSCs treated with succinate showed increased protein expression of GPR91 and a-SMA, markers of fibrogenic response. Transfection of siRNA against GPR91 abrogated succinate-induced increases in a-SMA expression (Montez et al, Endocrinology. 2012 Dec; 153(12): 5746-5759). All these data suggests role of GPR91 in liver disease like liver fibrosis, non alcoholic steatohepatitis.

[0008] GPR91 antagonists are useful as preservation solution or mechanical perfusion strategies for transplantation for various organs such as liver, kidney, heart. It can prolong preservation time; minimize allograft rejection or complications associated with transplantation. GPR91 antagonists can be administered to mammals including humans orally /iv/ip route, acute or chronic regimen to decrease allograft rejection or transplant complications.

[0009] Therefore, GPR91 antagonists could be useful for therapeutic intervention of multiple pathologic conditions like retinal neovascularization, age-related macular degeneration (AMD), wet macular degeneration (WMD), diabetic retinopathy, nonalcoholic steatohepatitis (NASH), liver fibrosis, Immune disorders, cancer, hypertension, blood pressure, as perfusion fluids for preservation of organs for transplant, decrease allograft rejection or transplant complications.

[00010] There remains a need to find new compounds that are inhibitors of GPR91 useful for the treatment of disease states mediated by GPR91. SUMMARY OF INVENTION

It is to be understood that the present disclosure includes all such variations and modifications. The disclosure also includes all such steps, features, compositions and compounds referred to or indicated in this specification, individually or collectively, and any and all combinations of any or more of such steps or features.

Definitions

[00015] For convenience, before further description of the present disclosure, certain terms employed in the specification, and examples are collected here. These definitions should be read in the light of the remainder of the disclosure and understood as by a person of skill in the art. The terms used herein have the meanings recognized and known to those of skill in the art, however, for convenience and completeness, particular terms and their meanings are set forth below.

[00016] The articles "a", "an" and "the" are used to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article.

[00017] Throughout the description and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers but not to the exclusion of any other integer or step or group of integers or steps.

[00018] The term "including" is used to mean "including but not limited to". "Including" and "including but not limited to" are used interchangeably.

[00019] In the structural Formulae given herein and throughout the present disclosure, the following terms have been indicated meaning, unless specifically stated otherwise.

[00020] Furthermore, the compound of Formula I can be its derivatives, analogs, stereoisomer' s, diastereomers, geometrical isomers, polymorphs, solvates, co-crystals, intermediates, metabolites, prodrugs or pharmaceutically acceptable salts and compositions.

[00021] The compounds of Formula I and their polymorphs, stereoisomers, prodrugs, solvates, co-crystals, intermediates, pharmaceutically acceptable salts, and metabolites thereof can also be referred as "compounds of the present disclosure".

[00022] The compounds according to Formula I may contain one or more asymmetric centres (also referred to as a chiral centres) and may, therefore, exist as individual enantiomers, diastereoisomers, or other stereoisomeric forms, or as mixtures thereof. Chiral centres, such as chiral carbon atoms, may also be present in a substituent such as an alkyl group. Where the stereochemistry of a chiral centre present in Formula I or in any chemical structure illustrated herein, is not specified, the structure is intended to encompass any stereoisomer and all mixtures thereof. Thus, compounds according to Formula I containing one or more chiral centres may be used as racemic modifications including racemic mixtures and racemates, enantiomerically-enriched mixtures, or as enantlomerically-pure individual stereoisomers. [00023] Individual stereoisomers of a compound according to Formula I which contain one or more asymmetric centres may be resolved by methods known to those skilled in the ait. For example, such resolution may be carried out (1) by formation of diastereoisomeric salts, complexes or other derivatives; (2) by selective reaction with a stereoisomer-specific reagent, for example by enzymatic oxidation or reduction; or (3) by gas-liquid or liquid chromatography in a chiral environment, for example, on a chiral support such as silica with a bound chiral ligand or in the presence of a chiral solvent. It will be appreciated that where the desired stereoisomer is converted into another chemical entity by one of the separation procedures described above, a further step is required to liberate the desired form.

[00024] Alternatively, specific stereoisomers may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents, or by converting one enantiomer to the other by asymmetric transformation.

[00025] It is to be understood that the references herein to compounds of Formula I and salts thereof covers the compounds of Formula I as free bases, or as salts thereof, for example as pharmaceutically acceptable salts thereof. Thus, in one embodiment, the invention is directed to compounds of Formula I as the free base. In another embodiment, the invention is directed to compounds of Formula I and salts thereof. In a further embodiment, the invention is directed to compounds of Formula I and pharmaceutically acceptable salts thereof.

[00026] It will be appreciated that pharmaceutically acceptable salts of the compounds according to Formula I may be prepared. Indeed, in certain embodiments of the invention, pharmaceutically acceptable salts of the compounds according to Formula I may be preferred over the respective free base because such salts impart greater stability or solubility to the molecule thereby facilitating Formulation into a dosage form. Accordingly, the invention is further directed to compounds of Formula I, and pharmaceutically acceptable salts thereof.

[00027] Included within the scope of the "compounds of the invention" are all solvates (including hydrates), complexes, polymorphs, prodrugs, radiolabeled derivatives, and stereoisomers of the compounds of Formula I, and salts thereof.

[00028] The compounds of the invention may exist in solid or liquid form. In the solid state, the compounds of the invention may exist in crystalline or non-crystalline form, or as a mixture thereof. For compounds of the invention that are in crystalline form, the skilled artisan will appreciate that pharmaceutically acceptable solvates may be formed wherein solvent molecules are incorporated into the crystalline lattice during crystallization. Solvates may involve nonaqueous solvents such as ethanol, isopropyl alcohol, dimethylsulfoxide (DM80), acetic acid, ethanolamine, and ethyl acetate, or they may involve water as the solvent that is incorporated into the crystalline lattice. Solvates wherein water is the solvent that is incorporated into the crystalline lattice are typically referred to as "hydrates". Hydrates include stoichiometric hydrates as well as compositions containing variable amounts of water. The invention includes all such solvates.

[00029] It will be further appreciated that certain compounds of the invention that exist in crystalline form, including the various solvates thereof, may exhibit polymorphism (i.e. the capacity to occur in different crystalline structures). These different crystalline forms are typically known as "polymorphs". The invention includes such polymorphs. Polymorphs have the same chemical composition but differ in packing, geometrical arrangement, and other descriptive properties of the crystalline solid state. Polymorphs, therefore, may have different physical properties such as shape, density, hardness, deformability, stability, and dissolution properties. Polymorphs typically exhibit different melting points, IR spectra, and X-ray powder diffraction patterns, which may be used for identification. It will be appreciated that different polymorphs may be produced, for example, by changing or adjusting the reaction conditions or reagents, used in making the compound. For example, changes in temperature, pressure, or solvent may result in polymorphs. In addition, one polymorph may spontaneously convert to another polymorph under certain conditions.

[00030] The term "polymorphs" refers to crystal forms of the same molecule, and different polymorphs may have different physical properties such as, for example, melting temperatures, heats of fusion, solubilities, dissolution rates and/or vibrational spectra as a result of the arrangement or conformation of the molecules in the crystal lattice. The compounds of the present disclosure may have the ability to crystallize in more than one form, a characteristic known as polymorphism, and all such polymorphic forms ("polymorphs") are encompassed within the scope of the present disclosure.

[00031] The term "substituted" in reference to a group indicates that a hydrogen atom attached to a member atom within a group is replaced.

In certain embodiments, a single atom may be substituted with more than one substituent as long as such substitution is in accordance with the permitted valence of the atom. Suitable substituents are defined herein for each substituted or optionally substituted group. The term "optionally substituted" as used herein means that the group in question is either unsubstituted or substituted with one or more of the substituents specified. When the group in question is substituted with more than one substituent, the substituent may be same or different.

Biological Assay

Human GPR91 calcium mobilization assay

[00014] To determine IC50 in CHO NFAT cells over expressing human GPR91 receptor calcium mobilization assay in flex station mode was carried out.

Tissue Culture

[00015] Grow CHO-K1 NFAT cells over expressing human GPR91 receptors in alpha

MEM media were supplemented with 10% FBS (heat inactivated), 0.5 mg/ml of G-418, 0.5 mg/ml of Zeocin and 0.6 mg/ml of Hygromycin B.

[00016] The cells were seeded at least 21 hours before the experiment at the density of

25000/well in 96 well plate (Corning cat# no. 3603). It was made sure that cells were at least 95 % confluent on the day of assay. No antibiotics were used for seeding purpose.

Dye Loading (Fluo4, AM)

[00017] On the day of assay the media was discarded from plates and plates were washed with 100 μΐ of HBSS assay buffer. The plates were loaded with Fluo4 AM at 2 μΜ concentration. Pluronic F-127 dye was solubilized in calcium assay buffer containing 0.1% BSA, i.e., 20μ1 dye+20μl Pluronic F127 for 10 ml. Appropriate amounts of 100X probenecid was added to the loading mixture IX final (ΙΟΟμΙ per 10ml). Total volume of dye loaded was made ΙΟΟμΙ. The plate was then wrapped in aluminium foil to protect from light and were incubated for 90 mins at 37 degrees in cell culture incubator. At the end of incubation the plates was washed again with 100 μΐ of HBSS buffer without BSA and 75 μΐ of HBSS buffer was added (without BSA) to the plate. [00018] Further, 8 point-Dose response curve of the compounds of the present disclosure was prepared in 100% DMSO followed by 57.14 -fold dilution to 1.75X in 1.75% DMSO in assay buffer. 100 μL of 1.75X NCE was added to the wells as shown below and incubated at room temp on orbital shaker at 300rpm for 15 min. Flexstation [excitation @ 485nm and emission @ 525nm] for a total time of 60 seconds. 25 μL of 8X agonist (800μΜ sodium succinate ) was added to each well using the flexstation after establishing the baseline for 20sec, Measurement - Max-Min over 60 sec. Using the above protocol results obtained are tabulate din the Table 1 below:
