CROSS-REFERENCE TO RELATED APPLICATIONS
The present application is a 371 of International Application No. PCT/US2013/070209 filed on Nov. 15, 2013, which claims priority benefit of U.S. provisional application Ser. No. 61/727,191, filed Nov. 16, 2012; each of which is fully incorporated by reference herein.


FIELD OF THE INVENTION
The present invention provides novel carboxylic acid substituted dihydropyrazole compounds, and their analogues thereof, which are GPR40 G protein-coupled receptor modulators, compositions containing them, and methods of using them, for example, for the treatment or prophylaxis of diabetes and related conditions.
BACKGROUND OF THE INVENTION
Diabetes mellitus is a progressively debilitating disorder of epidemic proportions leading to various micro- and macrovascular complications and morbidity. The most common type of diabetes, type 2 diabetes, is characterized by increasing insulin resistance associated with inadequate insulin secretion after a period of compensatory hyperinsulinemia. Free fatty acids (FFAs) are evidenced to influence insulin secretion from β cells primarily by enhancing glucose-stimulated insulin secretion (GSIS). G-protein coupled receptors (GPCRs) expressed in β cells are known to modulate the release of insulin in response to changes in plasma glucose levels. GPR40, also known as fatty acid receptor 1 (FFAR1), is a membrane-bound FFA receptor which is preferentially expressed in the pancreatic islets and specifically in β cells and mediates medium to long chain fatty acid induced insulin secretion. GPR40 is also expressed in enteroendocrine cells wherein activation promotes the secretion of gut incretin hormones, such as GLP-1, GIP, CCK and PYY. To decrease medical burden of type 2 diabetes through enhanced glycemic control, GPR40 modulator compounds hold the promise of exerting an incretin effect to promote GSIS as well as potential combination with a broad range of antidiabetic drugs.
The present invention relates to novel substituted dihydropyrazole compounds which have the ability to modulate GPR40. Such compounds are therefore potentially useful for the treatment or prophylaxis of diabetes and related conditions.
SUMMARY OF THE INVENTION
The present invention provides substituted dihydropyrazole compounds, and their analogues thereof, which are useful as GPR40 modulators, including stereoisomers, tautomers, pharmaceutically acceptable salts, or solvates thereof.
The present invention also provides processes and intermediates for making the compounds of the present invention or stereoisomers, tautomers, pharmaceutically acceptable salts, or solvates thereof.
The present invention also provides pharmaceutical compositions comprising a pharmaceutically acceptable carrier and at least one of the compounds of the present invention or stereoisomers, tautomers, pharmaceutically acceptable salts, or solvates thereof.
The compounds of the invention may be used in the treatment and/or prophylaxis of multiple diseases or disorders associated with GPR40, such as diabetes and related conditions, microvascular complications associated with diabetes, the macrovascular complications associated with diabetes, cardiovascular diseases, Metabolic Syndrome and its component conditions, disorders of glucose metabolism, obesity and other maladies.
The compounds of the invention may be used in therapy.
The compounds of the invention may be used for the manufacture of a medicament for the treatment and/or prophylaxis of multiple diseases or disorders associated with GPR40.
The compounds of the invention can be used alone, in combination with other compounds of the present invention, or in combination with one or more other agent(s).

Cis- and trans- (or E- and Z-) geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. The present compounds can be isolated in optically active or racemic forms. Optically active forms may be prepared by resolution of stereoisomeric forms or by synthesis from optically active starting materials. All processes used to prepare compounds of the present invention and intermediates made therein are considered to be part of the present invention. When enantiomeric or diastereomeric products are prepared, they may be separated by conventional methods, for example, by chromatography or fractional crystallization. Depending on the process conditions the end products of the present invention are obtained either in free (neutral) or salt form. Both the free form and the salts of these end products are within the scope of the invention. If so desired, one form of a compound may be converted into another form. A free base or acid may be converted into a salt; a salt may be converted into the free compound or another salt; a mixture of isomeric compounds of the present invention may be separated into the individual isomers. Compounds of the present invention, free form and salts thereof, may exist in multiple tautomeric forms, in which hydrogen atoms are transposed to other parts of the molecules and the chemical bonds between the atoms of the molecules are consequently rearranged. It should be understood that all tautomeric forms, insofar as they may exist, are included within the invention.
As used herein, the term “alkyl” or “alkylene” is intended to include both branched and straight-chain saturated aliphatic hydrocarbon groups having the specified number of carbon atoms.

The nitrogen and sulfur heteroatoms may optionally be oxidized (i.e., N→O and S(O)p, wherein p is 0, 1 or 2). The nitrogen atom may be substituted or unsubstituted (i.e., N or NR wherein R is H or another substituent, if defined). The heterocyclic ring may be attached to its pendant group at any heteroatom or carbon atom that results in a stable structure. The heterocyclic rings described herein may be substituted on carbon or on a nitrogen atom if the resulting compound is stable. A nitrogen in the heterocycle may optionally be quaternized.

As used herein, the term “bicyclic heterocycle” or “bicyclic heterocyclic group” is intended to mean a stable 9- or 10-membered heterocyclic ring system which contains two fused rings and consists of carbon atoms and 1, 2, 3, or 4 heteroatoms independently selected from the group consisting of N, O and S. Of the two fused rings, one ring is a 5- or 6-membered monocyclic aromatic ring comprising a 5-membered heteroaryl ring, a 6-membered heteroaryl ring or a benzo ring, each fused to a second ring. The second ring is a 5- or 6-membered monocyclic ring which is saturated, partially unsaturated, or unsaturated, and comprises a 5-membered heterocycle, a 6-membered heterocycle or a carbocycle (provided the first ring is not benzo when the second ring is a carbocycle).
The bicyclic heterocyclic group may be attached to its pendant group at any heteroatom or carbon atom which results in a stable structure. The bicyclic heterocyclic group described herein may be substituted on carbon or on a nitrogen atom if the resulting compound is stable. It is preferred that when the total number of S and O atoms in the heterocycle exceeds 1, then these heteroatoms are not adjacent to one another. It is preferred that the total number of S and O atoms in the heterocycle is not more than 1.
Examples of a bicyclic heterocyclic group are, but not limited to, quinolinyl, isoquinolinyl, phthalazinyl, quinazolinyl, indolyl, isoindolyl, indolinyl, 1H-indazolyl, benzimidazolyl, 1,2,3,4-tetrahydroquinolinyl, 1,2,3,4-tetrahydroisoquinolinyl, 5,6,7,8-tetrahydro-quinolinyl, 2,3-dihydro-benzofuranyl, chromanyl, 1,2,3,4-tetrahydro-quinoxalinyl, and 1,2,3,4-tetrahydro-quinazolinyl.
As used herein, the term “aromatic heterocyclic group” or “heteroaryl” is intended to mean stable monocyclic and polycyclic aromatic hydrocarbons that include at least one heteroatom ring member such as sulfur, oxygen, or nitrogen. Heteroaryl groups include, without limitation, pyridyl, pyrimidinyl, pyrazinyl, pyridazinyl, triazinyl, furyl, quinolyl, isoquinolyl, thienyl, imidazolyl, thiazolyl, indolyl, pyrroyl, oxazolyl, benzofuryl, benzothienyl, benzthiazolyl, isoxazolyl, pyrazolyl, triazolyl, tetrazolyl, indazolyl, 1,2,4-thiadiazolyl, isothiazolyl, purinyl, carbazolyl, benzimidazolyl, indolinyl, benzodioxolanyl, and benzodioxane. Heteroaryl groups are substituted or unsubstituted. The nitrogen atom is substituted or unsubstituted (i.e., N or NR wherein R is H or another substituent, if defined). The nitrogen and sulfur heteroatoms may optionally be oxidized (i.e., N→O and S(O)p, wherein p is 0, 1 or 2).
Examples of 5- to 6-membered heteroaryls include, but are not limited to, pyridinyl, furanyl, thienyl, pyrrolyl, pyrazolyl, pyrazinyl, imidazolyl, imidazolidinyl, tetrazolyl, isoxazolyl, oxazolyl, oxadiazolyl, oxazolidinyl, thiadiazinyl, thiadiazolyl, thiazolyl, triazinyl, and triazolyl.

The nitrogen and sulfur heteroatoms may optionally be oxidized (i.e., N→O and S(O)p, wherein p is 0, 1 or 2).
Examples of 5- to 6-membered heteroaryls include, but are not limited to, pyridinyl, furanyl, thienyl, pyrrolyl, pyrazolyl, pyrazinyl, imidazolyl, imidazolidinyl, tetrazolyl, isoxazolyl, oxazolyl, oxadiazolyl, oxazolidinyl, thiadiazinyl, thiadiazolyl, thiazolyl, triazinyl, and triazolyl.
Bridged rings are also included in the definition of heterocycle. A bridged ring occurs when one or more, preferably one to three, atoms (i.e., C, O, N, or S) link two non-adjacent carbon or nitrogen atoms. Examples of bridged rings include, but are not limited to, one carbon atom, two carbon atoms, one nitrogen atom, two nitrogen atoms, and a carbon-nitrogen group. It is noted that a bridge always converts a monocyclic ring into a tricyclic ring. When a ring is bridged, the substituents recited for the ring may also be present on the bridge.
The term “counter ion” is used to represent a negatively charged species such as chloride, bromide, hydroxide, acetate, and sulfate or a positively charged species such as sodium (Na+), potassium (K+), calcium (Ca2+)ammonium (RnNHm+ where n=0-4 and m=0-4) and the like.
When a dotted ring is used within a ring structure, this indicates that the ring structure may be saturated, partially saturated or unsaturated.
As used herein, the term “amine protecting group” means any group known in the art of organic synthesis for the protection of amine groups which is stable to an ester reducing agent, a disubstituted hydrazine, R4-M and R7-M, a nucleophile, a hydrazine reducing agent, an activator, a strong base, a hindered amine base and a cyclizing agent. Such amine protecting groups fitting these criteria include those listed in Wuts, P. G. M. and Greene, T. W. Protecting Groups in Organic Synthesis, 4th Edition, Wiley (2007) and The Peptides: Analysis, Synthesis, Biology, Vol. 3, Academic Press, New York (1981), the disclosure of which is hereby incorporated by reference. Examples of amine protecting groups include, but are not limited to, the following: (1) acyl types such as formyl, trifluoroacetyl, phthalyl, and p-toluenesulfonyl; (2) aromatic carbamate types such as benzyloxycarbonyl (Cbz) and substituted benzyloxycarbonyls, 1-(p-biphenyl)-1-methylethoxycarbonyl, and 9-fluorenylmethyloxycarbonyl (Fmoc); (3) aliphatic carbamate types such as tert-butyloxycarbonyl (Boc), ethoxycarbonyl, diisopropylmethoxycarbonyl, and allyloxycarbonyl; (4) cyclic alkyl carbamate types such as cyclopentyloxycarbonyl and adamantyloxycarbonyl; (5) alkyl types such as triphenylmethyl and benzyl; (6) trialkylsilane such as trimethylsilane; (7) thiol containing types such as phenylthiocarbonyl and dithiasuccinoyl; and (8) alkyl types such as triphenylmethyl, methyl, and benzyl; and substituted alkyl types such as 2,2,2-trichloroethyl, 2-phenylethyl, and t-butyl; and trialkylsilane types such as trimethylsilane.
As referred to herein, the term “substituted” means that at least one hydrogen atom is replaced with a non-hydrogen group, provided that normal valencies are maintained and that the substitution results in a stable compound. Ring double bonds, as used herein, are double bonds that are formed between two adjacent ring atoms (e.g., C═C, C═N, or N═N).
In cases wherein there are nitrogen atoms (e.g., amines) on compounds of the present invention, these may be converted to N-oxides by treatment with an oxidizing agent (e.g., mCPBA and/or hydrogen peroxides) to afford other compounds of this invention. Thus, shown and claimed nitrogen atoms are considered to cover both the shown nitrogen and its N-oxide (N→O) derivative.
When any variable occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-3 R, then said group may optionally be substituted with up to three R groups, and at each occurrence R is selected independently from the definition of R.
When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom in which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent.
Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.
The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms that 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, and/or other problem or complication, commensurate with a reasonable benefit/risk ratio.
As used herein, “pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic groups such as amines; and alkali or organic salts of acidic groups such as carboxylic acids. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, and nitric; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, and isethionic, and the like.
The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound that contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms 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, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington: The Science and Practice of Pharmacy, 22nd Edition, Allen, L. V. Jr., Ed.; Pharmaceutical Press, London, UK (2012), the disclosure of which is hereby incorporated by reference.
In addition, compounds of formula I may have prodrug forms. Any compound that will be converted in vivo to provide the bioactive agent (i.e., a compound of formula I) is a prodrug within the scope and spirit of the invention. Various forms of prodrugs are well known in the art. For examples of such prodrug derivatives, see:

Compounds containing a carboxy group can form physiologically hydrolyzable esters that serve as prodrugs by being hydrolyzed in the body to yield formula I compounds per se. Such prodrugs are preferably administered orally since hydrolysis in many instances occurs principally under the influence of the digestive enzymes. Parenteral administration may be used where the ester per se is active, or in those instances where hydrolysis occurs in the blood. Examples of physiologically hydrolyzable esters of compounds of formula I include C1-6alkyl, C1-6alkylbenzyl, 4-methoxybenzyl, indanyl, phthalyl, methoxymethyl, C1-6 alkanoyloxy-C1-6alkyl (e.g., acetoxymethyl, pivaloyloxymethyl or propionyloxymethyl), C1-6alkoxycarbonyloxy-C1-6alkyl (e.g., methoxycarbonyl-oxymethyl or ethoxycarbonyloxymethyl, glycyloxymethyl, phenylglycyloxymethyl, (5-methyl-2-oxo-1,3-dioxolen-4-yl)-methyl), and other well known physiologically hydrolyzable esters used, for example, in the penicillin and cephalosporin arts. Such esters may be prepared by conventional techniques known in the art.
Preparation of prodrugs is well known in the art and described in, for example, King, F. D., ed., Medicinal Chemistry: Principles and Practice, The Royal Society of Chemistry, Cambridge, UK (2nd edition, reproduced, 2006); Testa, B. et al., Hydrolysis in Drug and Prodrug Metabolism. Chemistry, Biochemistry and Enzymology, VCHA and Wiley-VCH, Zurich, Switzerland (2003); Wermuth, C. G., ed., The Practice of Medicinal Chemistry, 3rd edition, Academic Press, San Diego, Calif. (2008).
The present invention also includes isotopically-labeled compounds of the invention, wherein one or more atoms is replaced by an atom having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes suitable for inclusion in the compounds of the invention include isotopes of hydrogen, such as 2H (also represented as ‘ID’ for deuterium) and 3H, carbon such as 11C, 13C, and 14C, nitrogen, such as 13N and 15N, oxygen, such as 15O, 17O, and 18O. Certain isotopically-labeled compounds of the invention, for example, those incorporating a radioactive isotope, are useful in drug and/or substrate tissue distribution studies. The radioactive isotopes tritium, 3H, and carbon-14, 14C, are particularly useful for this purpose in view of their ease of incorporation and ready means of detection. Substitution with heavier isotopes such as deuterium, 2H, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increase in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. Substitution with positron emitting isotopes, such as 11C, 15O, 18F, and 13N, can be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy. Isotopically-labeled compounds of the invention can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described herein, using an appropriate isotopically-labeled reagent in place of the non-labeled reagent otherwise employed.
The term “solvate” means a physical association of a compound of this invention with one or more solvent molecules, whether organic or inorganic. This physical association includes hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. The solvent molecules in the solvate may be present in a regular arrangement and/or a non-ordered arrangement. The solvate may comprise either a stoichiometric or nonstoichiometric amount of the solvent molecules. “Solvate” encompasses both solution-phase and isolable solvates. Exemplary solvates include, but are not limited to, hydrates, ethanolates, methanolates, and isopropanolates. Methods of solvation are generally known in the art.

The compounds of the present invention can be prepared in a number of ways known to one skilled in the art of organic synthesis. The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or by variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. The reactions are performed in a solvent or solvent mixture appropriate to the reagents and materials employed and suitable for the transformations being effected. It will be understood by those skilled in the art of organic synthesis that the functionality present on the molecule should be consistent with the transformations proposed. This will sometimes require a judgment to modify the order of the synthetic steps or to select one particular process scheme over another in order to obtain a desired compound of the invention.
The novel compounds of this invention may be prepared using the reactions and techniques described in this section. Also, in the description of the synthetic methods described below, it is to be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of the experiment and workup procedures, are chosen to be the conditions standard for that reaction, which should be readily recognized by one skilled in the art. Restrictions to the substituents that are compatible with the reaction conditions will be readily apparent to one skilled in the art and alternate methods must then be used.
Synthesis
The compounds of Formula (I) may be prepared by the exemplary processes described in the following schemes and working examples, as well as relevant published literature procedures that are used by one skilled in the art. Exemplary reagents and procedures for these reactions appear hereinafter and in the working examples. Protection and de-protection in the processes below may be carried out by procedures generally known in the art (see, for example, Wuts, P. G. M. and Greene, T. W. Protecting Groups in Organic Synthesis, 4th Edition, Wiley (2007)). General methods of organic synthesis and functional group transformations are found in: Trost, B. M. and Fleming, I., eds., Comprehensive Organic Synthesis: Selectivity, Strategy & Efficiency in Modern Organic Chemistry, Pergamon Press, New York, N.Y. (1991); Smith, M.

Methods for synthesis of a large variety of substituted dihydropyrazole compounds useful as starting materials for the preparation of compounds of the present invention are well known in the art. For examples of methods useful for the preparation of dihydropyrazole materials see the following references and citations therein: Katritzky et al., eds., Comprehensive Heterocyclic Chemistry, Pergamon Press Inc., New York (1996); Sibi, M. P. et al., Organic Letters, 11(23): 5366 (2009); Sibi, M. P. et al., J. Am. Chem. Soc. 127(23): 8276 (2005); Manyem, S. et al., J. Comb.

Compounds for Formula (I) can be prepared as shown in Scheme 1. Conversion of the hydrazine A to the hydrazide B with trifluoroacetic anhydride followed by treatment with a phenylsulfonyl chloride forms the hydrazonoyl chloride C. A [3+2] cycloaddition of hydrazonoyl chloride C with methyl but-3-enoate mediated by optionally an activating agent and/or a silver salt forms the dihydropyrazole D. Intermediate D could be converted to compounds of Formula (I) by hydrolysis, via a hydroxide reagent, e.g., LiOH or NaOH.




Alternatively, hydrazonoyl chloride C could undergo a [3+2] cyclization with an α,β-unsaturated carbonyl compound where Y is a chiral auxiliary or alkoxy group to give dihydropyrazole E as depicted in Scheme 2. Reduction of the carbonyl E, via a reducing agent, e.g., NaBH4 or LiBH4, leads to hydroxyl F. Activation of the hydroxyl F, via methanesulfonyl chloride, for example, and displacement with a cyanide reagent, e.g., sodium cyanide, potassium cyanide or trimethylsilylcyanide, leads to nitrile G. The nitrile G can be converted to the methyl ester D by acidic methanolysis. Intermediate D could be converted to compounds of Formula (I) by hydrolysis, via a hydroxide reagent, e.g., LiOH or NaOH.




Exemplary activating agents include, but are not limited to, triethylamine, carbonate and bicarbonate. Exemplary silver salts include, but are not limited to, silver carbonate and silver acetate.
Compounds of Formula (I) may be synthesized starting with aniline H, which can be diazotized with NaNO2 and HCl and then converted to the hydrazonoyl chloride I via reaction with 2-chloro-3-oxobutanenitrile as shown in Scheme 3. A [3+2] cycloaddition of hydrazonoyl chloride I with methyl but-3-enoate mediated by an Ag salt forms the dihydropyrazole D. Intermediate D could be converted to compounds of Formula (I) by hydrolysis, via a hydroxide reagent, e.g., LiOH or NaOH.




Alternatively, compounds of Formula (I) can be synthesized via reaction of intermediate C or I with a substituted acrylate J in the presence of a Ag salt to provide dihydropyrazole E as depicted in Scheme 4. The methyl ester E is hydrolyzed, via LiOH, for example, to afford carboxylic acid K. The carboxylic acid K can be converted to the ester D, via an Arndt-Eistert homologation. Intermediate D could be converted to compounds of Formula (I) by hydrolysis, via a hydroxide reagent, e.g, LiOH or NaOH.




Compounds of Formula (I) may be synthesized starting with hydrazonoyl chlorides L containing a L.G. such as ═F, Cl, Br and the like, which can be converted to dihydropyrazoles M according to the sequence depicted in Scheme 2. The LG can be coupled via a Pd-catalyzed coupling to intermediate N that contains an organometallic, e.g. organozinc to generate intermediate D as shown in Scheme 5.




Alternatively, the hydrazonoyl chloride could contain a methyl ether 0, which could be converted to dihydropyrazole P according to the synthetic steps described in Scheme 2.

IV. Biology
Diabetes mellitus is a serious disease afflicting over 100 million people worldwide. It is diagnosed as a group of disorders characterized by abnormal glucose homeostasis resulting in elevated blood glucose. Diabetes is a syndrome with interrelated metabolic, vascular, and neuropathic components. The metabolic abnormality is generally characterized by hyperglycemia and alterations in carbohydrate, fat and protein metabolism caused by absent or reduced insulin secretion and/or ineffective insulin secretion. The vascular syndrome consists of abnormalities in the blood vessels leading to cardiovascular, retinal and renal complications. Abnormalities in the peripheral and autonomic nervous systems are also part of diabetic syndrome. Strikingly, diabetes is the fourth leading cause of global death by disease, the largest cause of kidney failure in developed countries, the leading cause of vision loss in industrialized countries and has the greatest prevalence increase in developing countries.
Type 2 diabetes, which accounts for 90% of diabetes cases, is characterized by increasing insulin resistance associated with inadequate insulin secretion after a period of compensatory hyperinsulinemia. The reasons for β cell secondary failure are not completely understood. Acquired pancreatic islet damage or exhaustion and/or genetic factors causing susceptibility to islet secretory insufficiency have been hypothesized.
Free fatty acids (FFAs) are evidenced to influence insulin secretion from β cells primarily by enhancing glucose-stimulated insulin secretion (GSIS). Although glucose is recognized as the major stimulator of insulin secretion from β cells, other stimuli, such as amino acids, hormones, and FFAs, also regulate insulin secretion. Thus, under normal settings, insulin secretion from β cells in response to food intake is evoked by the collective stimuli of nutrients, such as glucose, amino acids, and FFAs, and hormones like the incretin glucagon-like peptide 1 (GLP-1). Fatty acids are also known to stimulate the secretion of several gut satiety hormones, including cholocystokinine (CCK), GLP-1, and peptide YY (PYY).
G-protein coupled receptors (GPCRs) expressed in β cells are known to modulate the release of insulin in response to changes in plasma glucose levels. GPR40, also known as fatty acid receptor 1 (FFAR1), is a membrane-bound FFA receptor which is preferentially expressed in the pancreatic islets and specifically in β cells. GPR40 (e.g., human GPR40, RefSeq mRNA ID NM_005303; e.g., mouse GPR40 RefSeq mRNA ID NM_194057) is a GPCR located at chromosome 19q13.12. GPR40 is activated by medium to long chain fatty acids and thereby triggering a signaling cascade that results in increased levels of [Ca2+]i in β cells and subsequent stimulation of insulin secretion (Itoh et al., Nature, 422:173-176 (2003)). Selective small molecule agonists of GPR40 have been shown to promote GSIS and reduce blood glucose in mice (Tan et al., Diabetes, 57:2211-2219 (2008)). Briefly, when activators of GPR40 are administered to either normal mice or mice that are prone to diabetes due to genetic mutation, prior to a glucose tolerance test, improvements in glucose tolerance are observed. A short-lived increase in plasma insulin levels are also observed in these treated mice. It has also been shown that GPR40 agonists restore GSIS in pancreatic β-cells from the neonatal STZ rats suggesting that GPR40 agonists will be efficacious in diabetics with compromised β-cell function and mass. Fatty acids are known to stimulate the secretion of several gut satiety hormones, including cholocystokinine (CCK), GLP-1, and peptide YY (PYY), and GPR40 has been shown to colocalize with cells that secrete such hormones (Edfalk et al., Diabetes, 57:2280-2287 (2008) Luo et al. PLOSone, 7:1-12 (2012)). Fatty acids are also known to play a role in neuronal development and function, and GPR40 has been reported as a potential modulator of the fatty acid effects on neurons (Yamashima, T., Progress in Neurobiology, 84:105-115 (2008)).
Given the increase in the worldwide patient population afflicted by type 2 diabetes, there is a need for novel therapies which are effective with minimal adverse events. To decrease medical burden of type 2 diabetes through enhanced glycemic control, GPR40 modulator compounds of the present invention are being investigated here for their incretin effect to promote GSIS as well as the potential combination with a broad range of anti-diabetic drugs.
The term “modulator” refers to a chemical compound with capacity to either enhance (e.g., “agonist” activity) or partially enhance (e.g., “partial agonist” activity) or inhibit (e.g., “antagonist” activity or “inverse agonist” activity) a functional property of biological activity or process (e.g., enzyme activity or receptor binding); such enhancement or inhibition may be contingent on the occurrence of a specific event, such as activation of a signal transduction pathway, receptor internalization, and/or may be manifest only in particular cell types.
It is also desirable and preferable to find compounds with advantageous and improved characteristics compared with known anti-diabetic agents, in one or more of the following categories that are given as examples, and are not intended to be limiting: (a) pharmacokinetic properties, including oral bioavailability, half life, and clearance; (b) pharmaceutical properties; (c) dosage requirements; (d) factors that decrease blood drug concentration peak-to-trough characteristics; (e) factors that increase the concentration of active drug at the receptor; (f) factors that decrease the liability for clinical drug-drug interactions; (g) factors that decrease the potential for adverse side-effects, including selectivity versus other biological targets; and (h) improved therapeutic index with less propensity for hypoglycemia.
As used herein, the term “patient” encompasses all mammalian species.
As used herein, the term “subject” refers to any human or non-human organism that could potentially benefit from treatment with a GPR40 modulator. Exemplary subjects include human beings of any age with risk factors for metabolic disease. Common risk factors include, but are not limited to, age, sex, weight, family history, or signs of insulin resistance such as acanthosis nigricans, hypertension, dislipidemia, or polycystic ovary syndrome (PCOS).
As used herein, “treating” or “treatment” cover the treatment of a disease-state in a mammal, particularly in a human, and include: (a) inhibiting the disease-state, i.e., arresting it development; and/or (b) relieving the disease-state, i.e., causing regression of the disease state.
As used herein, “prophylaxis” or “prevention” cover the preventive treatment of a subclinical disease-state in a mammal, particularly in a human, aimed at reducing the probability of the occurrence of a clinical disease-state. Patients are selected for preventative therapy based on factors that are known to increase risk of suffering a clinical disease state compared to the general population. “Prophylaxis” therapies can be divided into (a) primary prevention and (b) secondary prevention. Primary prevention is defined as treatment in a subject that has not yet presented with a clinical disease state, whereas secondary prevention is defined as preventing a second occurrence of the same or similar clinical disease state.
As used herein, “risk reduction” covers therapies that lower the incidence of development of a clinical disease state. As such, primary and secondary prevention therapies are examples of risk reduction.
“Therapeutically effective amount” is intended to include an amount of a compound of the present invention that is effective when administered alone or in combination to modulate GPR40 and/or to prevent or treat the disorders listed herein. When applied to a combination, the term refers to combined amounts of the active ingredients that result in the preventive or therapeutic effect, whether administered in combination, serially, or simultaneously.
In Vitro GPR40 Assays
FDSS-Based Intracellular Calcium Assay
Cell lines expressing GPR40 are generated using the pDEST 3× flag gene expression system and are cultured in culture medium comprising the following components: F12 (Gibco #11765), 10% lipid deprived fetal bovine serum, 250 μg/ml zeocin and 500 μg/ml G418. To conduct the fluorescent imaging plate reader (FLIPR)-based calcium flux assay to measure intracellular Ca2+ response, cells expressing GPR40 are plated on 384 well plates (BD Biocoat #356697) at a density of 20,000 cells/20 μL medium per well in phenol red and serum-free DMEM (Gibco #21063-029) and incubated overnight. Using BD kit #s 80500-310 or -301, the cells are incubated with 20 μL per well of Hank's buffered salt solution with 1.7 mM probenecid and Fluo-3 at 37° C. for 30 min. Compounds are dissolved in DMSO and diluted to desired concentrations with assay buffer and added to the cells as 3x solution (20 μL per well). Run fluorescence/luminescence reader FDSS (Hamamatsu) to read intracellular Ca2+ response.
The exemplified Examples disclosed below were tested in the Human GRP40 In Vitro assay described above and found having hGRP40 modulating activity.
GPR40 IP-One HTRF Assays in HEK293/GPR40 Inducible Cell Lines
Human, mouse and rat GPR40-mediated intracellular IP-One HTRF assays were established using human embryonic kidney HEK293 cells stably transfected with a tetracycline-inducible human, mouse or rat GPR40 receptor. Cells were routinely cultured in growth medium containing DMEM (Gibco Cat. #:12430-047), 10% qualified FBS (Sigma, Cat. #: F2442), 200 μg/mL hygromycin (Invitrogen, Cat. #: 16087-010) and 1.5 μg/mL blasticidin (Invitrogen, Cat. # R210-01). About 12-15 million cells were passed into a T175 tissue culture flask (BD Falcon 353112) with growth medium and incubated for 16-18 hours (overnight) at 370 C with 5% CO2. The next day, assay medium was exchanged with growth medium containing 1000 μg/mL of tetracycline (Fluka Analytical, Cat. #87128) to induce GPR40 expression for 18-24 hours at 370 C incubator with 5% CO2. After induction, the cells were washed with PBS (Gibco, Cat. #14190-036) and detached with Cell Stripper (Cellgro, Cat. #25-056-CL). 10-20 mL growth medium were added to the flask and cells were collected in 50 mL tubes (Falcon, Cat.#:352098) and spun at 1000 RPM for 5 minutes. Culture medium was aspirated and the cells were resuspended in 10 mL of 1× IP-One Stimulation Buffer from the Cisbio IP-One kit (Cisbio, Cat. #62IPAPEJ). The cells were diluted to 1.4×106 cells/mL in Stimulation Buffer.
Test compounds were 3-fold, 11-point serially diluted in DMSO in a REMP assay plate (Matrix Cat. #: 4307) by BioCel (Agilent). The compounds were transferred into an Echo plate (LABCYTE, Cat. #: LP-0200) and 20 nL of diluted compounds were transferred to an assay plate (proxi-plate from Perkin Elmer, Cat. #6008289) by Echo acoustic nano dispenser (LABCYTE, model ECHO550). 14 μL of the diluted cells were then added to the assay plate by Thermo (SN 836 330) Combi Drop and incubated at room temperature for 45 minutes. Then 3 μL of IP1 coupled to dye D2 from the Cisbio IP-One kit were added to the assay plate followed by 3 μL of Lumi4TM-Tb cryptate K from the kit. The plate was further incubated at room for 1 hour before reading on the Envision (Perkin Elmer Mode12101) with an HTRF protocol. Activation data for the test compound over a range of concentrations was plotted as percentage activation of the test compound (100%=maximum response). After correcting for background [(sample read-mean of low control)/(mean of high control−mean of low control)] (low control is DMSO without any compound), EC50 values were determined. The EC50 is defined as the concentration of test compound which produces 50% of the maximal response and was quantified using the 4 parameter logistic equation to fit the data. The maximal Y value observed (% Ymax) was calculated relative to a BMS standard reference compound at a final concentration of 0.625 μM.
Some of the exemplified Examples disclosed below were tested in the Human GRP40 In Vitro assay described above and found having hGRP40 modulating activity reported as hGPR40 IP1 EC50.
In Vivo GPR40 Assays
Acute Oral Glucose Tolerance Test
Ten week old C57BL6 mice were housed individually and fasted for 5 hours on the day of study. Tail vein sampling was performed from nicked tails to obtain plasma samples. Baseline plasma samples were taken at t=0. Mice were orally treated with vehicle or compounds co-administered with glucose (2 g/kg). Sampling thereafter from tails of treated mice at 20, 40, 60, 120 and 180 min provided data used for generating glucose excursion curves from which 0-180 min blood glucose excursion profiles were generated. The area under the curve (AUC) allowed for assessment of glucose lowering by compound treatments. Blood samples were collected in EDTA-treated tubes (microvette CB300, Sarstedt, Numbrecht, Germany), stored on ice and spun @ 6000 rpm for 10 minutes. Plasma glucose was analyzed on the same day using an AU680 Clinical Chemistry Analyzer (Beckman Coulter, Brea, Calif.). Statistical analysis is a one way ANOVA with Dunnett's post hoc test or two-way student's t test where appropriate. P values less than 0.05 were considered statistically significant. Glucose reduction is reported as a % change in AUC (0-180 min) from the vehicle treatment group. For example, “Acute oral glucose tolerance: −50% @ 0.3 mg/kg” represents the results of a study as described above, whereupon administration of 0.3 mg/kg of the specified example results in a 50% reduction in glucose AUC (0-180 min) relative to vehicle treated animals.
Acute Oral Glucose Tolerance Test in Rats
Male Sprague Dawley rats (CRL, Wilmington Mass.) were used. Rats were delivered to the vivarium and acclimated for 1 week. Rats were fasted from 5 PM on the night before study. Overnight fasted rats were 180-200 grams at time of study. Tail vein sampling was performed to obtain baseline plasma samples. Rats were randomized to treatment groups based on fasting plasma glucose readings determined by Accu-Chek® glucometer (Roche, Indianapolis, Ind.). Rats were dosed at 4 mL/Kg body weight with 40% PEG400 (Sigma, St. Louis, Mo.) 10% Cremophore (Sigma, St. Louis, Mo.) and 50% distilled water with or without compounds. For rats that received BMS DPP4i combined with GPR40 agonist, administration was performed by co-dosing compounds. Plasma samples were collected one hour after compound dosing to determine baseline changes in glucose and active GLP-1 levels in the presence and absence of BMS DPP4i. Sampling thereafter from tail veins provided time point data to calculate AUC0-120, glucose as a marker of two hour glucose lowering efficacy. Blood samples were collected in EDTA-treated tubes (microvette CB300, Sarstedt, Numbrecht, Germany), stored on ice and spun @ 6000 rpm for 10 minutes. Plasma glucose was analyzed on the same day using an AU680 Clinical Chemistry Analyzer (Beckman Coulter, Brea, Calif.). Statistical analysis is a one way ANOVA with Dunnett's post hoc test or two-way student's t test where appropriate. P values less than 0.05 were considered statistically significant. Glucose reduction is reported as a % change in AUC (0-120 min) from the vehicle treatment group. Fasting hormone responses are the difference from basal levels 1 hour post dose. Active GLP-1 levels (GLP-1 (7-36) amide and GLP-1 (7-37)) were measured by ELISA (Millipore, Billerica, Mass.).
BMS DPP4i—Reference Compound
BMS DPP4i is disclosed in Simpkins, L. et al. Bioorganic Medicinal Chemistry Letters 2007, 17(23), 6476-80 (compound 48) and in WO2005012249 (Example 3). BMS DPP4i has the following formula:




BMS DPP4i was administered to rats alone, and in combination with Example 81, Isomer 2 of the present invention, at 10 mg/kg, as depicted in FIG. 1 and FIG. 2. As depicted in FIG. 1, the combination of BMS DPP4i with Example 81, Isomer 2 demonstrated greater reductions in plasma glucose during an oral glucose tolerance test than either Example 81, Isomer 2 or BMS DPP4i alone. As depicted in FIG. 2, the combination of BMS DPP4i with Example 81, Isomer 2 shows greater increases in active GLP-1 during an oral glucose tolerance test than either Example 81, Isomer 2 or BMS DPP4i alone.

These include, without limitation: the type and nature of the active agent being formulated; the subject to which the agent-containing composition is to be administered; the intended route of administration of the composition; and the therapeutic indication being targeted. Pharmaceutically acceptable carriers include both aqueous and non-aqueous liquid media, as well as a variety of solid and semi-solid dosage forms. Such carriers can include a number of different ingredients and additives in addition to the active agent, such additional ingredients being included in the formulation for a variety of reasons, e.g., stabilization of the active agent, binders, etc., well known to those of ordinary skill in the art. Descriptions of suitable pharmaceutically acceptable carriers, and factors involved in their selection, are found in a variety of readily available sources such as, for example, Allen, L. V. Jr. et al. Remington: The Science and Practice of Pharmacy (2 Volumes), 22nd Edition (2012), Pharmaceutical Press.

By way of general guidance, the daily oral dosage of each active ingredient, when used for the indicated effects, will range between about 0.001 to about 5000 mg per day, preferably between about 0.01 to about 1000 mg per day, and most preferably between about 0.1 to about 250 mg per day. Intravenously, the most preferred doses will range from about 0.01 to about 10 mg/kg/minute during a constant rate infusion. Compounds of this invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily.
The compounds are typically administered in admixture with suitable pharmaceutical diluents, excipients, or carriers (collectively referred to herein as pharmaceutical carriers) suitably selected with respect to the intended form of administration, e.g., oral tablets, capsules, elixirs, and syrups, and consistent with conventional pharmaceutical practices.
Dosage forms (pharmaceutical compositions) suitable for administration may contain from about 1 milligram to about 2000 milligrams of active ingredient per dosage unit. In these pharmaceutical compositions the active ingredient will ordinarily be present in an amount of about 0.1-95% by weight based on the total weight of the composition.

No. 5,614,492 to Habener, the disclosure of which is incorporated herein by reference), which may be administered via injection, intranasal, or by transdermal or buccal devices. Reviews of current and emerging therapies for the treatment of obesity can be found in: Melnikova, I. et al., Nature Reviews Drug Discovery, 5:369-370 (2006); Jones, D., Nature Reviews: Drug Discovery, 8:833-834 (2009); Obici, S., Endocrinology, 150(6):2512-2517 (2009); and Elangbam, C. S., Vet. Pathol., 46(1):10-24 (2009).
The above other therapeutic agents, when employed in combination with the compounds of the present invention may be used, for example, in those amounts indicated in the Physicians' Desk Reference, as in the patents set out above, or as otherwise determined by one of ordinary skill in the art.
Particularly when provided as a single dosage unit, the potential exists for a chemical interaction between the combined active ingredients. For this reason, when the compound of the present invention and a second therapeutic agent are combined in a single dosage unit they are formulated such that although the active ingredients are combined in a single dosage unit, the physical contact between the active ingredients is minimized (that is, reduced). For example, one active ingredient may be enteric coated. By enteric coating one of the active ingredients, it is possible not only to minimize the contact between the combined active ingredients, but also, it is possible to control the release of one of these components in the gastrointestinal tract such that one of these components is not released in the stomach but rather is released in the intestines. One of the active ingredients may also be coated with a material that affects a sustained-release throughout the gastrointestinal tract and also serves to minimize physical contact between the combined active ingredients. Furthermore, the sustained-released component can be additionally enteric coated such that the release of this component occurs only in the intestine. Still another approach would involve the formulation of a combination product in which the one component is coated with a sustained and/or enteric release polymer, and the other component is also coated with a polymer such as a low viscosity grade of hydroxypropyl methylcellulose (HPMC) or other appropriate materials as known in the art, in order to further separate the active components. The polymer coating serves to form an additional barrier to interaction with the other component.
These as well as other ways of minimizing contact between the components of combination products of the present invention, whether administered in a single dosage form or administered in separate forms but at the same time by the same manner, will be readily apparent to those skilled in the art, once armed with the present disclosure.
The compounds of the present invention can be administered alone or in combination with one or more additional therapeutic agents. By “administered in combination” or “combination therapy” it is meant that the compound of the present invention and one or more additional therapeutic agents are administered concurrently to the mammal being treated. When administered in combination, each component may be administered at the same time or sequentially in any order at different points in time. Thus, each component may be administered separately but sufficiently closely in time so as to provide the desired therapeutic effect.
The compounds of the present invention are also useful as standard or reference compounds, for example as a quality standard or control, in tests or assays involving the GPR40 receptor. Such compounds may be provided in a commercial kit, for example, for use in pharmaceutical research involving GPR40 or anti-diabetic activity. For example, a compound of the present invention could be used as a reference in an assay to compare its known activity to a compound with an unknown activity. This would ensure the experimentor that the assay was being performed properly and provide a basis for comparison, especially if the test compound was a derivative of the reference compound. When developing new assays or protocols, compounds according to the present invention could be used to test their effectiveness.
The compounds of the present invention may also be used in diagnostic assays involving GPR40.
The present invention also encompasses an article of manufacture. As used herein, article of manufacture is intended to include, but not be limited to, kits and packages.
