CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a U.S. National Phase application under 35 U.S.C. §371 of PCT Application No. PCT/US2012/041847, filed Jun. 11, 2012, which published as WO 2012/173917 on Dec. 20, 2012, and claims priority under 35 U.S.C. §119 from U.S. Provisional Application No. 61/497,703, filed Jun. 16, 2011 and U.S. Provisional Application No. 61/655,010, filed Jun. 4, 2012.


BACKGROUND OF THE INVENTION
The present invention relates to G-protein coupled receptor agonists. In particular, the present invention is directed to agonists of GPR 119 that are useful for the treatment of diabetes, especially type 2 diabetes, as well as related diseases and conditions such as obesity and metabolic syndrome.
Diabetes is a disease derived from multiple causative factors. It is characterized by elevated levels of plasma glucose (hyperglycemia) in the fasting state or after administration of glucose during an oral glucose tolerance test. There are two generally recognized forms of diabetes. In type 1 diabetes, or insulin-dependent diabetes mellitus (IDDM), patients produce little or no insulin, the hormone which regulates glucose utilization. In type 2 diabetes, or noninsulin-dependent diabetes mellitus (T2DM), insulin is still produced in the body, and patients demonstrate resistance to the effects of insulin in stimulating glucose and lipid metabolism in the main insulin-sensitive tissues, namely, muscle, liver and adipose tissue. These patients often have normal levels of insulin, and may have hyperinsulinemia (elevated plasma insulin levels), as they compensate for the reduced effectiveness of insulin by secreting increased amounts of insulin.
There has been renewed focus on pancreatic islet-based insulin secretion that is controlled by glucose-dependent insulin secretion (GDIS). In this regard, several orphan G-protein coupled receptors (GPCR's) have recently been identified that are preferentially expressed in the β-cell and are implicated in GDIS. GPR119 is a cell-surface GPCR that is highly expressed in human (and rodent) islets as well as in insulin-secreting cell lines. Synthetic GPR119 agonists augment the release of insulin from isolated static mouse islets only under conditions of elevated glucose, and improve glucose tolerance in diabetic mice and diet-induced obese (DIO) C57/B6 mice without causing hypoglycemia. Novel GPR119 agonists therefore have the potential to function as anti-hyperglycemic agents that produce weight loss.

The invention is described herein in detail using the terms defined below unless otherwise specified.
The invention is described herein in detail using the terms defined below unless otherwise specified. “Alkyl”, as well as other groups having the prefix “alk”, such as alkoxy, and the like, means carbon chains which may be linear or branched, or combinations thereof, containing the indicated number of carbon atoms. If no number is specified, 1-6 carbon atoms are intended for linear and 3-7 carbon atoms for branched alkyl groups. Examples of alkyl groups include methyl, ethyl, propyl, isopropyl, butyl, sec- and tert-butyl, pentyl, hexyl, heptyl, octyl, nonyl and the like.
As used herein, “cycloalkyl” means a saturated cyclic hydrocarbon radical having the number of carbon atoms designated. If no number of atoms is specified, 3-7 carbon atoms are intended, forming 1-3 carbocyclic rings that are fused. “Cycloalkyl” also includes monocyclic rings fused to an aryl group in which the point of attachment is on the non-aromatic portion. Examples of cycloalkyl include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, tetrahydronaphthyl, decahydronaphthyl, indanyl and the like.
“Alkoxy” refers to an alkyl group linked to oxygen.
“Haloalkoxy” and “haloalkylO” are used interchangeably and refer to halo substituted alkyl groups linked through the oxygen atom. Haloalkoxy include mono-substituted as well as multiple halo substituted alkoxy groups, up to perhalo substituted alkoxy. For example, trifluoromethoxy is included.
“Haloalkyl” include mono-substituted as well as multiple halo substituted alkyl groups, up to perhalo substituted alkyl. For example, trifluoromethyl is included.
As used herein, “heterocycle” or “heterocyclic” refers to nonaromatic cyclic ring structures in which one or more atoms in the ring, the heteroatom(s), is an element other than carbon. Heteroatoms are typically O, S or N atoms.
“Heteroaryl” (HAR) unless otherwise specified, means an aromatic or partially aromatic heterocycle that contains at least one ring heteroatom selected from oxygen (“O”), sulfur (“S”) and nitrogen (“N”). Heteroaryls thus includes heteroaryls fused to other kinds of rings, such as aryls, cycloalkyls and heterocycles that are not aromatic. Examples of heteroaryl groups include: pyrrolyl or pyrrole, isoxazolyl or isoxazole, isothiazolyl or isothiazole, pyrazolyl or pyrazole, pyridyl, oxazolyl or oxazole, oxadiazolyl or oxadiazole, thiadiazolyl or thiadiazole, thiazolyl or thiazole, imidazolyl or imidazole, triazolyl or triazole, tetrazolyl or tetrazole, furyl, triazinyl, thienyl, pyrimidyl, benzisoxazolyl or benzisoxazole, benzoxazolyl or benzoazole, benzothiazolyl or benzothiazole, benzothiadiazolyl or benzothiadiazole, dihydrobenzofuranyl or dihydrobenzofurane, indolinyl or indoline, pyridazinyl or pyridazine, indazolyl or indazole, isoindolyl or isoindole, dihydrobenzothienyl, indolizinyl or indolizine, cinnolinyl or cinnoline, phthalazinyl or phthalazine, quinazolinyl or quinazoline, naphthyridinyl or naphthyridine, carbazolyl or carbazole, benzodioxolyl or benzodioxole, quinoxalinyl or quinoxaline, purinyl or purine, furazanyl or furazane, isobenzylfuranyl or isobenzylfurane, benzimidazolyl or benzimidazole, benzofuranyl or benzofurane, benzothienyl or benzothiene, quinolyl or quinoline, oxo-dihydroqunoline, indolyl or indole, oxindole, isoquinolyl or isoquinoline, dibenzofuranyl or dibenzofurane, and the like. For heterocyclic and heteroaryl groups, rings and ring systems containing from 5-15 atoms are included, forming 1-3 rings.
“Halogen” (Halo) includes fluorine, chlorine, bromine and iodine.
Unless expressly depicted or described otherwise, variables depicted in a structural formula with a “floating” bond, such as each of substituents R1 and R2, are permitted on any available carbon atom in the ring to which each is attached.
Substitution, where applicable, may be on any available carbon atom that results in a stable structure.
In the compounds described herein, the atoms may exhibit their natural isotopic abundances, or one or more of the atoms may be artificially enriched in a particular isotope having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number predominantly found in nature. The present invention is meant to include all suitable isotopic variations of the compounds of the formulas described herein. For example, different isotopic forms of hydrogen (H) include protium (1H) and deuterium (2H). Protium is the predominant hydrogen isotope found in nature. Enriching for deuterium may yield certain therapeutic advantages, such as increasing in vivo half-life or reducing dosage requirements, or may provide a compound useful as a standard for characterization of biological samples. Isotopically-enriched compounds within the formulas described herein can be prepared without undue experimentation by conventional techniques well known to those skilled in the art or by processes analogous to those described in the Schemes and Examples herein using appropriate isotopically-enriched reagents and/or intermediates.
The individual tautomers of the compounds of the formulas described herein, as well as mixture thereof, are encompassed with compounds of the formulas described herein. Tautomers are defined as compounds that undergo rapid proton shifts from one atom of the compound to another atom of the compound. Some of the compounds described herein may exist as tautomers with different points of attachment of hydrogen. Such an example may be a ketone and its enol form known as keto-enol tautomers.
Compounds of the formulas described herein may be separated into diastereoisomeric pairs of enantiomers by, for example, fractional crystallization from a suitable solvent. The pair of enantiomers thus obtained may be separated into individual stereoisomers by conventional means, for example by the use of an optically active amine or acid as a resolving agent or on a chiral HPLC column.
Alternatively, any enantiomer of a compound of the formulas described herein may be obtained by stereospecific synthesis using optically pure starting materials or reagents of known configuration.
It is generally preferable to administer compounds of the present invention as enantiomerically pure formulations. Racemic mixtures can be separated into their individual enantiomers by any of a number of conventional methods. These include chiral chromatography, derivatization with a chiral auxiliary followed by separation by chromatography or crystallization, and fractional crystallization of diastereomeric salts.
Compounds described herein may contain an asymmetric center and may thus exist as enantiomers. Where the compounds according to the invention possess two or more asymmetric centers, they may additionally exist as diastereomers. When bonds to the chiral carbon are depicted as straight lines in the formulas of the invention, it is understood that both the (R) and (S) configurations of the chiral carbon, and hence both enantiomers and mixtures thereof, are embraced within the formulas. The present invention includes all such possible stereoisomers as substantially pure resolved enantiomers, racemic mixtures thereof, as well as mixtures of diastereomers. Except where otherwise specified, the formulae encompassing compounds of the present invention are shown without a definitive stereochemistry at certain positions. The present invention therefore may be understood to include all stereoisomers of compounds of Formula I and pharmaceutically acceptable salts thereof.
Diastereoisomeric pairs of enantiomers may be separated by, for example, fractional crystallization from a suitable solvent, and the pair of enantiomers thus obtained may be separated into individual stereoisomers by conventional means, for example by the use of an optically active acid or base as a resolving agent or on a chiral HPLC column. Further, any enantiomer or diastereomer of a compound of the general Formula I or Ia may be obtained by stereospecific synthesis using optically pure starting materials or reagents of known configuration.
Furthermore, some of the crystalline forms for compounds of the present invention may exist as polymorphs and as such are intended to be included in the present invention. In addition, some of the compounds of the instant invention may form solvates with water or common organic solvents. Solvates, and in particular, the hydrates of the compounds of the structural formulas described herein are also included in the present invention.
Compounds of the present invention are potent agonists of the GPR 119 receptor. These compounds and pharmaceutically acceptable salts thereof are modulators of the receptor known as GPR 119, and are therefore useful in the treatment of diseases that are modulated by GPR119 ligands and agonists. Many of these diseases are summarized below. Said compounds may be used for the manufacture of a medicament for treating one or more of diseases or conditions, including, without limitation:

    
    
        (1) noninsulin dependent diabetes mellitus (type 2 diabetes);
        (2) hyperglycemia;
        (3) metabolic syndrome/syndrome X;

The compounds are useful to ameliorate hyperinsulinemia, which often occurs in diabetic or pre-diabetic patients, by modulating the swings in the level of serum glucose that often occurs in these patients. The compounds are useful for treating or reducing insulin resistance. The compounds are useful for treating or preventing gestational diabetes.
Additionally, by keeping hyperglycemia under control, the compounds are useful to delay or for preventing vascular restenosis and diabetic retinopathy.
The compounds of this invention are useful in improving or restoring β-cell function, so that they may be useful in treating type 1 diabetes or in delaying or preventing a patient with type 2 diabetes from needing insulin therapy.
The compounds, compositions, and medicaments as described herein are further useful for reducing the risks of adverse sequelae associated with metabolic syndrome, or Syndrome X, and in reducing the risk of developing atherosclerosis, delaying the onset of atherosclerosis, and/or reducing the risk of sequelae of atherosclerosis. Sequelae of atherosclerosis include angina, claudication, heart attack, stroke, and others.
The compounds may be useful for reducing appetite and body weight in obese subjects and may therefore be useful in reducing the risk of co-morbidities associated with obesity such as hypertension, atherosclerosis, diabetes, and dyslipidemia.
By elevating levels of active GLP-1 in vivo, the compounds are useful in treating neurological disorders such as Alzheimer's disease, multiple sclerosis, and schizophrenia.

For dosing purposes, any suitable route of administration may be employed for providing a mammal, especially a human, with an effective amount of a compound of the present invention. Dosage forms may include tablets, troches, dispersions, suspensions, solutions, capsules, creams, ointments, aerosols, and the like. Most preferably, compounds of the formulas described herein or a pharmaceutically acceptable salt thereof are administered orally. The effective dosage of active ingredient employed may vary depending on the particular compound employed, the mode of administration, the condition being treated and the severity of the condition being treated. Such dosage may be ascertained readily by a person skilled in the art.
When treating or controlling diabetes mellitus or other diseases for which compounds of the formulas described herein are indicated, generally satisfactory results are obtained when the compounds of the present invention are administered at a daily dosage of from about 0.1 milligram to about 100 milligram per kilogram of animal body weight, preferably given as a single daily dose or in divided doses two to six times a day, or in sustained release form. For most large mammals, the total daily dosage is from about 1.0 milligrams to about 1000 milligrams. In the case of a 70 kg adult human, the total daily dose will generally be from about 1 milligram to about 350 milligrams. For a particularly potent compound, the dosage for an adult human may be as low as 0.1 mg. The dosage regimen may be adjusted within this range or even outside of this range to provide the optimal therapeutic response. Oral administration will usually be carried out using tablets or capsules. Examples of doses in tablets and capsules are 0.1 mg, 0.25 mg, 0.5 mg, 1 mg, 1.5 mg, 2 mg, 2.5 mg, 3 mg, 3.5 mg, 4 mg, 4.5 mg, 5 mg, 5.5 mg, 6 mg, 6.5 mg, 7 mg, 7.5 mg, 8 mg, 8.5 mg, 9 mg, 9.5 mg, 10 mg, 12 mg, 15 mg, 20 mg, 25 mg, 50 mg, 100 mg, 200 mg, 350 mg, 500 mg, 700 mg, 750 mg, 800 mg and 1000 mg. Other oral forms may also have the same or similar dosages.
Another aspect of the invention that is of interest is a pharmaceutical composition comprised of a compound of the formulas described herein or a pharmaceutically acceptable salt thereof in combination with a pharmaceutically acceptable carrier. The pharmaceutical compositions of the present invention comprise a compound of the formulas described herein or a pharmaceutically acceptable salt as an active ingredient, as well as a pharmaceutically acceptable carrier and optionally other therapeutic ingredients. The term “pharmaceutically acceptable salts” refers to salts prepared from pharmaceutically acceptable non-toxic bases or acids including inorganic bases or acids and organic bases or acids.
Salts of basic compounds encompassed within the term “pharmaceutically acceptable salt” refer to non-toxic salts of the compounds described herein which are generally prepared by reacting the free base with a suitable organic or inorganic acid. Representative salts of basic compounds described herein include, but are not limited to, the following: acetate, benzenesulfonate, benzoate, bicarbonate, bisulfate, bitartrate, borate, bromide, camsylate, carbonate, chloride, clavulanate, citrate, edetate, edisylate, estolate, esylate, formate, fumarate, gluceptate, gluconate, glutamate, hexylresorcinate, hydrobromide, hydrochloride, hydroxynaphthoate, iodide, isothionate, lactate, lactobionate, laurate, malate, maleate, mandelate, mesylate, methylbromide, methylnitrate, methylsulfate, mucate, napsylate, nitrate, N-methylglucamine ammonium salt, oleate, oxalate, palmitate, pamoate (embonate), pantothenate, phosphate/diphosphate, polygalacturonate, salicylate, stearate, sulfate, subacetate, succinate, tannate, tartrate, teoclate, tosylate, triethiodide and valerate. Furthermore, where the compounds described herein carry an acidic moiety, suitable pharmaceutically acceptable salts thereof include, but are not limited to, salts derived from inorganic bases including aluminum, ammonium, calcium, copper, ferric, ferrous, lithium, magnesium, manganic, mangamous, potassium, sodium, zinc, and the like. Particularly preferred are the ammonium, calcium, magnesium, potassium, and sodium salts.

A pharmaceutical composition may also comprise a prodrug, or a pharmaceutically acceptable salt thereof, if a prodrug is administered.
The compositions are typically suitable for oral, rectal, topical, parenteral (including subcutaneous, intramuscular, and intravenous), ocular (ophthalmic), pulmonary (nasal or buccal inhalation), or nasal administration, although the most suitable route in any given case will depend on the nature and severity of the condition being treated and on the particular active ingredient selected. They may be conveniently presented in unit dosage form and prepared by any of the methods well-known in the art.
In practical use, compounds of the formulas described herein, or the pharmaceutically acceptable salts thereof can be combined as the active ingredient in intimate admixture with the pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier may take a wide variety of forms depending on the form of preparation desired for administration, e.g., oral or parenteral (including intravenous). In preparing the compositions for oral dosage form, any of the usual pharmaceutical media may be employed, such as, for example, water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents and the like in the case of oral liquid preparations, such as, for example, suspensions, elixirs and solutions; or carriers such as starches, sugars, microcrystalline cellulose, diluents, granulating agents, lubricants, binders, disintegrating agents and the like in the case of oral solid preparations such as, for example, powders, hard and soft capsules and tablets, with the solid oral preparations being preferred over the liquid preparations.
Because of their ease of administration, tablets and capsules represent the most advantageous oral dosage form. Solid pharmaceutical carriers are therefore typically employed. If desired, tablets may be coated by standard aqueous or nonaqueous techniques. Such compositions and preparations typically comprise at least about 0.1 percent of active compound, the remainder of the composition being the carrier. The percentage of active compound in these compositions may, of course, be varied and is conveniently between about 2 percent to about 60 percent of the weight of the dosage form. The amount of active compound in such therapeutically useful compositions is such that an effective dosage will be delivered.
Alternatively, the active compound can be administered intranasally as, for example, in the form of liquid drops or a spray.
The tablets, capsules and the like also typically contain a binder. Examples of suitable binders include gum tragacanth, acacia, gelatin and a synthetic or semisynthetic starch derivative, such as hydroxypropylmethylcellulose (HPMC); excipients such as dicalcium phosphate; a disintegrating agent such as corn starch, potato starch, alginic acid; a lubricant such as magnesium stearate; and in some instances, a sweetening agent such as sucrose, lactose or saccharin. When the dosage form employed is a capsule, it may contain, in addition to the components described above, a liquid carrier such as fatty oil.
Various other materials may be present as coatings or to modify the physical form of the dosage unit. For instance, tablets may be coated with shellac, sugar or both. Syrups and elixirs typically contain, in addition to the active ingredient, sucrose as a sweetening agent, methyl or propylparabens as a preservative, a dye and a flavoring such as cherry or orange flavor.
The compound of the formulas described herein or a pharmaceutically acceptable salt thereof may also be administered parenterally. Solutions or suspensions of these active compounds can be prepared in water, saline or another biocompatible vehicle, suitably mixed with a surfactant, buffer, and the like. Dispersions can also be prepared in glycerol, liquid polyethylene glycols and mixtures thereof in an oil. Under ordinary conditions of storage and use, these preparations can also contain a preservative to prevent the growth of microorganisms.
The pharmaceutical forms suitable for injectable use include sterile aqueous solutions and dispersions, and sterile powders for the extemporaneous preparation of sterile injectable solutions and dispersions. The preparation should be prepared under sterile conditions and be fluid to the extent that easy syringability exists. It should be sufficiently stable under the conditions of manufacture and storage and preserved against the growth of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g. glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and suitable oils.
As discussed supra, compounds of the present invention may be used in combination with other drugs that may also be useful in the treatment or amelioration of the diseases and conditions described herein. Such other drugs may be administered by a route and in an amount commonly used therefore, contemporaneously or sequentially with a compound of the formulas described herein or a pharmaceutically acceptable salt thereof. In the treatment of patients who have type 2 diabetes, insulin resistance, obesity, metabolic syndrome, neurological disorders, and co-morbidities that accompany these diseases, more than one drug is commonly administered. The compounds of this invention may generally be administered to a patient who is already taking one or more other drugs for these conditions.
When a compound of the formulas described herein is used contemporaneously with one or more other drugs, a pharmaceutical composition in unit dosage form containing such other drugs and the compound of the formulas described herein is preferred. However, the combination therapy also includes therapies in which a compound of the formulas described herein and one or more other drugs are administered on different overlapping schedules. It is also contemplated that when used in combination with one or more other active ingredients, the compound of the present invention and the other active ingredients may be used in lower doses than when each is used singly.

Another aspect of the invention that is of interest relates to the use of a compound in accordance with the formulas described herein or a pharmaceutically acceptable salt thereof in the manufacture of a medicament for use in treating a disease or condition described herein.
The compounds of the invention can be prepared using the synthetic schemes described herein as well as any of several alternate methods which will be apparent to a chemist skilled in the art. The following abbreviations may be used in the synthetic schemes or Examples: BuTMDOB is trans 2-butyl-N,N,N,N-tetramethyl-1,3,2-dioxaborolane-4,5-dicarboxamide, as specified R,R or S,S; CBz is carbobenzyloxy; CPME is cyclopentyl methyl ether; DCM is dichloromethane; DMAP is dimethylaminopyridine; DMF is N,N-dimethylformamide; DMSO is dimethyl sulfoxide; EDC is 1-ethyl-3-[3-(dimethylamino)propyl]-carbodiimide HCl; EtOAc is ethyl acetate; EtOH is ethanol; HCl is hydrochloric acid; HOBt is 1-hydroxybenzotriazole; HPLC is high performance liquid chromatography; iPrOAc is isopropyl acetate; KHMDS is potassium hexamethyldisilazane; LRMS is low resolution mass spectrometry; M is molar; mmol is millimole; NaHMDS is sodium hexamethyldisilazane; n-BuLi is n-butyllithium; RTis RT; OTf is triflate; PPh3 is triphenylphosphine; TEA is triethylamine; TFA is trifluoroacetic acid; THF is tetrahydrofuran; TLC is thin layer chromatography; TPAP is tetrapropylammonium perruthenate.
Reaction Schemes below illustrate in exemplary fashion the methods employed in the synthesis of the compounds of the present invention of Formula I; other routes may be contemplated as well.
General Schemes
Substituted aryl and heteroaryl coupling intermediates shown in the schemes are commercially available or may be prepared from readily accessible aryl, heterocyclic, or other congeners via a host of routes. Many intermediates are accessible through either modification of a pre-formed heteroaryl scaffold or through de novo ring synthesis.
The cyclopropyl residue in the connecting chain of the present examples may be introduced by any of several methods. A particularly convenient method is outlined in Scheme 1 below. Conversion of the readily available piperidine aldehyde to the acetylene by a multistep protocol allows ready access to the indicated cis olefins after Lindlar reduction. Charette's Et2Zn/CH2I2 cyclopropanation yields racemic, diastereomerically or enantiomerically enriched cyclopropyl analogs. In the absence of an auxiliary chiral Lewis acid the cis allylic olefins yield good yields of the desired racemic analogs.
With the addition of the auxiliary chiral Lewis acid RR or SS BuTMDOB, the same cyclopropanation protocol leads to very good ratios of the desired enantiomer.




Using the alcohols prepared as outlined in scheme 1, many analogs may be prepared by different routes. Scheme 2 outlines a particularly convenient method for conversion of the cyclopropyl alcohol to substituted aryl/heteroaryl alkyl ethers via treatment with aryl/heteroaryl alkyl halides in the presence of a base, such as NaHMDS or KHMDS usually heated to 70° C., for a period of 2 to 24 hours. Depending on the amino protecting group, several methods can be used for removal which will be apparent to a chemist skilled in the art. For example, most commonly used t-butylcarbonyl can be removed via treatment with an acid, e.g., HCl or TFA. Another commonly used protecting group is CBz which can be removed via hydrogenation.




The cyclopropyl alcohol can be converted to a leaving group such as a tosylate or iodide via treatment with tosyl chloride in the presence of an organic base, such as TEA, and an activating agent, such as DMAP, in the appropriate solvent, or by treatment with iodine and triphenylphosphine in the presence of imidazole. This tosylate/iodide can then be treated with the choice of aryl/heteroaryl alkyl alcohols in the presence of base, such as sodium hydride to form the desired aryl/heteroaryl alkyl ethers.




Introduction of the piperidine nitrogen substituent can be accomplished by a particularly wide variety of routes. Some of the most versatile routes for the examples reported here are represented in the following schemes. The formation of carbamate analogs are outlined in Scheme 4. Commercially available alkyl or aryl chloroformates or preformed succinimides can be used in the acylation of the nitrogen of the cyclopropyl intermediate with a base such as DIEA or TEA, to yield the carbamate GPR119 agonist analogs. This procedure is particularly useful for targeting several different carbamate analogs of a particularly interesting aryl or heteroarylalkyl ether.





Introduction of the piperidine nitrogen 5-membered heterocyclic substituents can be accomplished by a number of routes. One of the most versatile routes for the examples reported here are represented in scheme 5. The amine of the piperidine is converted to a cyano substituted piperidine by treatment with cyanogen bromide in the presence of base in a suitable chlorinated solvent at temperatures from 0° C. to reflux. The cyano intermediate can then be converted to a 3-substituted 1,2,4-oxadiazole by zinc chloride mediated reaction with an N-hydroxyalkylimidamide or N-hydroxyarylimidamide, followed by acid mediated cyclization.




Direct displacement of labile heteroaryl halides or other leaving groups can often be used to introduce the nitrogen substituent directly as shown in scheme 6.




The order of introduction of piperidine N substituents and aryl/heteroarylalkyl ether is easily inverted by removal of piperidine protecting group first. Following derivatisation of the piperidine nitrogen using the methods outlined in the above schemes, further elaboration of the primary alcohol may be achieved by base mediated reaction with aryl/heteroarylalkyl halide, or activation of the alcohol to a leaving group and displacement with aryl/heteroarylalkyl alcohol as outlined in scheme 7.




When the N-Aryl or N-heteroaryl residue is substituted with an X group (where X=Cl, Br, I or OTf) it is possible to further functionalize the residue by utilizing palladium mediated coupling reactions. Methods with extraordinarily broad applicability are metal based couplings outlined in scheme 8.




Similarly when the ring A residue is substituted with an X group (where X=Cl, Br, I or OTf), it is possible to further functionalize the residue by utilizing palladium mediated coupling reactions. Methods with extraordinarily broad applicability are metal based couplings outlined in scheme 9.

Compounds of the present invention were shown to be biologically active in one or more of the following assays:
Measurement of GPR119 Signaling Using LANCE 384-Well cAMP Kit
Human embryonic kidney (HEK) 293 cell lines stably transfected with human GPR119 were maintained in DMEM media containing FBS, penicillin-streptomycin, HEPES, and hygromycin. For the cAMP assay, the transfected cells were harvested using a non-enzymatic cell dissociation solution (GIBCO 2672), pelleted and resuspended in stimulation buffer (DMEM, 25 mM Hepes, 0.1% BSA, pH 7.4 in the presence of 100 μM phosphodiesterase inhibitors). The adenylate cyclase assay was constructed following the LANCETM cAMP Kit (Perkin Elmer, AD0264) instructions. Briefly, cells with Alexa Fluor® 647-anti cAMP antibody were incubated with 10 point series diluted test article in stimulation buffer with a final concentration of 2.5% DMSO for 45 minutes. The reaction was stopped by incubating with the supplied detection buffer containing the europium chelate of the Eu-SA/Biotin-cAMP tracer for 3 hours. The assay was performed in duplicate in a 384 well plate for duplicate plates. Fluorescence at 665 nm was measured using a PHERAstar instrument. Basal activity was determined using a DMSO control and maximum response was defined as cAMP stimulation produced by an internal agonist control. Standard cAMP concentrations were assayed concurrently for conversion of fluorescence signal to cAMP level. The data was analyzed using 4-parameter curve fit in Microsoft Excel.
Measurement of GPR119 Signaling Using a Cyclic AMP (cAMP) Homogenous Time Resolved Fluorescence (HTRF) Assay
Chinese hamster ovary (CHO) cell lines stably transfected with the permissive guanine nucleotide binding protein alpha 15 (Gα15) and murine GPR119 were maintained in DMEM media containing FBS, penicillin-streptomycin, puromycin, and G418 (geneticin). Alternatively, human embryonic kidney (HEK)293 Flp-In cells (Invitrogen, Carlsbad, Calif.) were stably transfected with a human SNP variant (S309L) of GPR119 and maintained in DMEM media containing FBS, penicillin-streptomycin, and hygromycin. Agonist activation of the GPR119 receptor was measured in receptor transfected cells described above, treated with compounds of this invention, using a commercial homogenous time resolved fluorescence (HTRF) kit for measurement of cAMP (CisBio, Bedford, Mass.). The assay was performed in 96-well half-volume plates (murine) or 384-well plates (human) following the manufacturers instructions. Briefly, suspended cells were incubated with a dose titration of test compound at RT for 60 min, lysed, and incubated with HTRF reagents for an additional 60 min. The plate was read using an Envision multilabel reader (Perkin Elmer) adjusted to read time resolved fluorescence and the cAMP concentrations were extrapolated from a cAMP calibration curve. GPR119 agonists will exhibit a concentration-dependent increase in intracellular cAMP. The concentration of test compound required to stimulate a half-maximal response (EC50), and efficacy as compared to an internal agonist control, was determined from a sigmoidal 4-parameter curve fit of the resulting plot of normalized activity versus compound concentration.
Evaluation of Glucose Dependent Insulin Secretion (GDIS) in Static Isolated Mouse Islets.
Pancreatic islets of Langerhans were isolated from the pancreata of 10-12 wk-old C57BL/6 mice by collagenase digestion and discontinuous Ficoll gradient separation, a modification of the original method of Lacy and Kostianovsky (Lacy & Kostianovsky, 1967 Diabetes 16-35-39). The islets were cultured overnight in RPMI 1640 medium (11 mM glucose, 10% FCS) before experimental treatment. The acute effects of compounds of this invention on GDIS were determined by 60-min static incubation with islets in Krebs-Ringers' bicarbonate (KRB) medium. The KRB medium contained, in mM, 143.5 Na+, 5.8 K+, 2.5 Ca2+, 1.2 Mg2+, 124.1 Cl−, 1.2 PO43−, 1.2 SO42+, 25 CO32−, and 10 HEPES, pH 7.4, in addition to 2 mg/ml bovine serum albumin, and either 2 (G2) or 16 (G16) mM glucose (pH 7.4). The static incubation was performed with round-bottomed 96-well plates (one islet/well with 200 μl KRB medium). The compounds were added to KRB medium just before the initiation of the 60-min incubation. Insulin concentration in aliquots of the incubation buffer was measured by the ultra-sensitive rat insulin EIA kit from ALPCO Diagnostics (Windham, N.H.).
