Substituted biphenyls

FIELD

This application claims the benefit of U.S. Provisional application No. 60/228,822.

BACKGROUND

The present invention concerns certain substituted pyridines, processes for the production thereof, and the use thereof in pharmaceutical products. It also concerns certain substituted biphenyls, processes for their production, pharmaceutical compositions containing them, and methods for their use.

7-(polysubstituted pyridyl) hept-6-enoates for the treatment of arteriosclerosis, lipoproteinemia, and hyperlipoproteinemia are known from U.S. Pat. No. 5,169,857. In addition, the production of 7-(4-aryl-3-pyridyl)-3,5-dihydroxy-hept-6-enoate is described in EP 325 130.

Glucagon is a peptide hormone whose main function is to increase hepatic glucose production. Insulin, on the other hand, functions to decrease glucose production. Together, these two hormones are necessary for maintaining a correct level of glucose in the blood.

Diabetes is a complex disease characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Diabetes is also associated with elevated glucagon levels. The heterogeneous nature of the disease requires different strategies to address the different abnormalities in metabolism found in affected individuals.

In the diabetic state (all forms of Type I and Type II), hyperglycemia often is associated with elevated glucagon levels. Accordingly, a means of treating all forms of diabetes is to block the glucagon receptor with a suitable antagonist, thereby inhibiting glucose production by the liver and reducing glucose levels in the patient.

Glucagon receptor antagonists, materials which block the action of endogenous glucagon, are known to have many and varied applications. Among these applications are the following:

1. Treatment of hyperglycemia associated with diabetes of any cause and associated with any other diseases or conditions. A glucagon receptor antagonist can be used either alone or in combination with any other therapies to treat hyperglycemia.

2. Treatment of impaired glucose tolerance (IGT).

3. Treatment of insulin resistance syndromes including those due to obesity, polycystic ovarian syndrome, “Syndrome X”, drugs and hormones, endocrinopathies and genetic syndromes.

4. To decrease free fatty acid levels and treat conditions associated with elevated free fatty acids levels such as insulin resistance, obesity, all or part of Syndrome X, Type I and II diabetes, hyperlipidemias and elevated hepatic glucose output associated with insulin resistance, Type I and Type II diabetes, obesity, and Syndrome X.

5. To treat conditions associated with genetic defects in insulin action due to alterations in insulin receptor structure and function or alterations in post receptor signal transduction. To treat diabetes associated with anti-insulin antibodies, drug induced diabetes, diabetes associated with endocrinopathies and diabetes associated with genetic syndromes.

6. To treat gestational diabetes mellitus.

7. To treat autoimmune and non autoimmune causes of Type I diabetes including those due to known genetic defects of the beta cell, pancreatic diseases, drug or toxin induced beta cell dysfunction, endocrinopathies, infectious causes, malnutrition associated and idiopathic Type I diabetes.

8. To prevent and treat diabetic ketoacidosis and decrease hepatic ketone body production

9. To treat hyperglycemia of exercise in diabetes.

10. To reduce fasting and postprandial glucose.

11. Treatment of insulin resistance in liver, muscle, and fat.

12. Treatment of conditions of hyperlipidemia.

13. To treat glucagonomas and all other conditions associated with elevated glucagon levels.

14. To treat conditions of increased futile cycling of glucose in the liver.

15. To increase insulin secretion.

16. To decrease glucose toxicity.

17. To decrease the renal prostaglandin response to protein and amino acids.

18. To decrease elevated GFR and albumin clearance due to diabetes or proteins or amino acids.

19. To decrease renal albumin clearance and excretion.

20. To treat acute pancreatitis.

21. To treat cardiovascular disease including causes of increased cardiac contractility.

22. To treat cardiac hypertrophy and its consequences.

23. As a diagnostic agent and as a diagnostic agent to identify patients having a defect in the glucagon receptor.

24. Treatment of gastrointestinal disorders, treatment of decreased gut motility.

25. As a therapy to increase gastric acid secretions.

26. To reverse intestinal hypomobility due to glucagon administration.

27. To reverse catabolism and nitrogen loss in states of negative nitrogen balance and protein wasting including all causes of Type I and Type II diabetes, fasting, AIDS, cancer, anorexia, aging and other conditions.

28. To treat any of the above conditions or diseases in post-operative or operative period.

29. To decrease satiety and increase energy intake.

Glucagon receptor antagonists of the prior art, such as those described in WO9518153-A and references cited therein, are predominantly peptide analogues of glucagon. They are susceptible to the actions of endogenous proteases, may precipitate antibody production and immune reactions and can be difficult and expensive to manufacture. Such peptides are usually unsuitable for oral delivery.

One non-peptide glucagon receptor antagonist has been reported (Collins, et al;

BioMed. Chem Lett.

1992, 2, 915-918). This quinoxaline derivative, CP-99,711, was shown to inhibit glucagon binding and glucagon action in rat liver membrane at micromolar concentrations.

It would be desirable to have inhibitors of CETP which possess valuable pharmacological properties that are superior to those of the state of the art. Certain of the substituted pyridine compounds of the invention are highly effective inhibitors of cholesterol ester transfer proteins (CETP) and stimulate reverse cholesterol transport. They cause a reduction in LDL cholesterol levels in the blood, while at the same time increasing HDL cholesterol levels. They can therefore be used for the treatment of hyperlipoproteinemia or arteriosclerosis.

It would also be desirable to have readily prepared non-peptidic glucagon receptor antagonists which are metabolically more stable than peptidic antagonists of the prior art, and which afford good activity and bioavailability. Certain of the substituted pyridine compounds as well as the substituted biphenyls of the invention are highly effective inhibitors of the glucagon receptor. Accordingly, these compounds may be used to treat glucagon-mediated conditions such as those listed above.

The pharmacological action of the substances according to the invention was determined in the following test:

CETP Inhibition Test

1. Obtaining CETP

CETP is obtained in partially purified form from human plasma by differential centrifugation and column chromatography and is used for testing. In so doing, human plasma is adjusted with NaBr to a density of 1.21 g per ml and is centrifuged for 18 h at 50,000 rpm at 4° C. The bottom fraction (d>1.21 g/ml) is applied to a Sephadex® Phenyl-Sepharose 4B (Pharmacia) column, washed with 0.15 m NaCl/0.001 m TrisHCl, pH 7.4, and then eluted with dist. water. The CETP-active fractions were pooled, dialyzed against 50 mM Na acetate, pH 4.5, and applied to a CM-Sepharose® (Pharmacia) column. They were then eluted with a linear gradient (0-1 M NaCl). The pooled CETP fractions were dialyzed against 10 mM TrisHCl, pH 7.4, and were then further purified by chromatography over a Mono Q® column (Pharmacia).

2. Obtaining Radioactively Tagged HDL

50 ml of fresh human EDTA plasma was adjusted with NaBr to a density of 1.12 and centrifuged at 4° C. for 18 h at 50,000 rpm in the Ty 65 rotor. The upper phase was used to obtain cold LDL. The lower phase was dialyzed against 3×4 l of PDB buffer (10 mM Tris/HCl, pH 7.4, 0.15 mM NaCl, 1 mM EDTA, 0.02% NaN

3

). 20 μl 3H cholesterol (Du Pont NET-725; 1 -μC/μl dissolved in ethanol) was subsequently added per 10 ml of dialysis residue volume and incubated for 72 h at 37° C. under N

2

.

The sediment was then adjusted with NaBr to a density of 1.21 and centrifuged in the Ty 65 rotor for 18 h at 50,000 rpm at 20° C. The upper phase was obtained and the lipoprotein fractions were purified by gradient centrifugation. In so doing, the isolated, tagged lipoprotein fraction was adjusted with NaBr to a density of 1.26. Every 4 ml of this solution was covered in centrifuge tubes (SW 40 rotor) with 4 ml of a solution with a density of 1.21 and 4.5 ml of a solution with a density of 1.063 (density solutions from PDB buffer and NaBr) and then centrifuged for 24 h at 38,000 rpm and 20° C. in the SW 40 rotor. The intermediate layer between the densities 1.063 and 1.21 that contained the tagged HDL was dialyzed against 3×100 volumes of PDB buffer at 4° C.

The dialysis residue contained radioactively tagged

3

H-CE-HDL, which was adjusted to approx. 5×10

6

cpm per ml and used for the test.

3. Conducting the Test

In order to test the CETP activity, the transfer of

3

H cholesterol ester from human HD lipoproteins to biotinylated LD lipoproteins was measured.

The reaction was ended by adding Streptavidin-SPA® beads (Amersham), and the transferred radioactivity was determined directly in the liquid scintillation counter.

In the test batch, 10 μl HDL-

3

H cholesterol ester (≈50,000 cpm) was incubated for 18 h at 37° C. with 10 μl biotin-LDL (Amersham) in 50 mM HEPES/0.15 m NaCl/0.1% bovine serum albumin/0.05% NaN

3

, pH 7.4, with 10 μl CETP (1 mg/ml) and 3 μl solution of the substance to be tested (dissolved in 10% DMSO/1% BSA). Then 200 μl of the SPA-Streptavidin bead solution (Amersham TRKQ 7005) was added, and the mixture was further incubated for 1 h under agitation and subsequently measured in the scintillation counter. Corresponding incubations with 10 μl buffer, 10 μl CETP at 4° C., and 10 μl CETP at 37° C. served as controls.

The transferred activity in the control batches with CETP at 37° C. was assessed as 100% transfer. The substance concentration in which this transfer was reduced by half was indicated as an IC

value.

Syrian golden hamsters from the company's own breeding were anesthetized after fasting for 24 h (0.80 mg/kg atropine, 0.80 mg/kg Ketavet® s.c., 30′ later 50 mg/kg Nembutal i.p.). The jugular vein was then exposed and cannulated. The test substance was dissolved in a suitable solvent (as a rule, Adalat placebo solution: 60 g glycerin, 100 ml H

2

O, ad 100 ml PEG-400) and administered to the animals via a PE catheter inserted into the jugular vein. The control animals received the same volume of solvent without any test substance. The vein was then ligated and the wound closed up. At different intervals—up to 24 hours after administration of the test substance—blood was drawn from the animals by puncture of the retroorbital venous plexus (approx. 250 μl). Coagulation was completed by incubating at 4° C. overnight, then the blood was centrifuged for 10 minutes at 6000 g. The cholesterol and triglyceride content in the serum obtained in this manner was determined using modified commercially available enzyme tests (cholesterol enzymatic 14366 Merck, triglyceride 14364 Merck). The serum was diluted in a suitable manner with physiological saline solution.

100 μl serum dilution was mixed with 100 μl test substance in 96-hole perforated plates and incubated 10 minutes at room temperature. The optical density was then determined with an automatic plate reader at a wavelength of 492 nM (SLT-Spectra). The triglyceride/cholesterol concentration contained in the samples was determined using a parallel-measured standard curve.

The determination of the HDL cholesterol content was carried out after precipitation of the lipoproteins containing Apo B by means of a reagent mixture (Sigma 352-4 HDL cholesterol reagent) according to the manufacturer's instructions.

In attempting to determine oral efficacy, the test substance, which was dissolved in DMSO and suspended in 0.5% methylcellulose, was administered orally to Syrian golden hamsters from the company's own breeding via a pharyngeal tube. The control animals received identical volumes of solvent without any test substance. Feed was then withheld from the animals and blood was drawn at different intervals—up to 24 hours after administration of the substance—via puncture of the retroorbital venous plexus. It was further processed as described above.

The new active compounds can be converted in a known manner into the customary formulations, such as tablets, coated tablets, pills, granules, aerosols, syrups, emulsions, suspensions, and solutions, using inert, non-toxic, pharmaceutically suitable excipients or solvents. In this connection, the therapeutically active compound should be present in each case in a concentration of about 0.5% to 90% by weight, i.e., in amounts that are sufficient to achieve the dosage range indicated.

The formulations are prepared, for example, by extending the active compounds using solvents and/or excipients, if appropriate using emulsifiers and/or dispersants, where, for example, in the case of the use of water as a diluent, organic solvents can be used, if appropriate, as auxiliary solvents.

The administration takes place in a customary manner, preferably orally or parenterally, in particular, perlingually or intravenously.

In the case of parenteral use, solutions of the active compound can be employed using suitable liquid excipients.

In general, it has proved advantageous in intravenous administration to administer amounts of about 0.001 to 1 mg/kg, preferably about 0.01 to 0.5 mg/kg of body weight, to attain effective results, and in oral administration, the dosage is about 0.01 to 20 mg/kg, preferably 0.1 to 10 mg/kg of body weight.

In spite of this, it may be necessary to deviate from the amounts mentioned, depending on the body weight or the type of administration route, individual behavior toward the medication, the type of formulation thereof, and the time or interval at which administration takes place. Thus, in some cases it may be sufficient to manage with less than the minimum amount previously mentioned, whereas in other cases the upper limit mentioned must be exceeded. If larger amounts are administered, it may be advisable to divide these into several individual doses over the day.

However, the reductions can also be carried out with reductants that are suitable for the reduction of ketones to hydroxy compounds. Particularly suitable in this regard is reduction using metal hydrides or complex metal hydrides in inert solvents, if appropriate, in the presence of a trialkyl borane. Preferably, the reduction is carried out using complex metal hydrides such as lithium borohydride, sodium borohydride, potassium borohydride, zinc borohydride, lithium trialkylborohydride, or lithium aluminum hydride. More preferably, the reaction is carried out using sodium borohydride in the presence of triethyl borane.

It may possibly be necessary to carry out several reaction steps under a protective gas atmosphere.

The halogenations generally take place in one of the above-mentioned chlorinated hydrocarbons, with methylene chloride being preferred.

Diethylamino sulfur trifluoride (DAST) or SOCl

2

, for example, are suitable halogenation agents.

The halogenation generally takes place within a temperature range of −78° C. to +50° C., preferably from −78° C. to 0° C., and particularly preferably at −78° C., depending on the choice of both the halogenation agent and the solvent.

The halogenation generally takes place at normal pressure, but it is also possible to work at increased or reduced pressure.

The customary reagents are suitable as Wittig reagents. 3-Trifluoro-methylbenzyltriphenylphosphonium bromide is preferred.

are identical or different and denote straight-chain or branched alkyl with up to 4 carbon atoms,

through oxidation into the corresponding pyridines and finally depending on the substituents a reduction according to conventional methods can be carried out.

Suitable solvents for the oxidation are ethers such as diethyl ether, dioxane, tetrahydrofuran, or glycol dimethyl ether; or hydrocarbons such as benzene, toluene, xylene, hexane, or cyclohexane, or petroleum fractions, or halocarbons such as dichloromethane, trichloromethane, tetrachloromethane, dichloroethylene, or trichloroethylene, or chlorobenzene, or ethyl acetate, or triethylamine, pyridine, dimethylsulfoxide, dimethylformamide, hexamethylphosphoric triamide, acetonitrile, acetone, or nitromethane.

The 3-heteroalkyl-aryl-substituted pyridines according to the invention possess valuable pharmacological properties that are superior to those of the state of the art; in particular, they are highly effective inhibitors of cholesterol ester transfer proteins (CETP) and stimulate reverse cholesterol transport. The active compounds according to the invention cause a reduction in LDL cholesterol levels in the blood, while at the same time increasing HDL cholesterol levels. They can therefore be used for the treatment of hyperlipoproteinemia or arteriosclerosis.

The invention additionally concerns the combination of compounds according to the invention with a glucosidase and/or amylase inhibitor for the treatment of familial hyperlipidemia, obesity (adiposis), and diabetes meritus. Within the context of the invention, glucosidase and/or amylase inhibitors are, for example, acarbose, adiposine, voglibose, miglitol, emiglitate, MDL-25637, camiglibose (MDL-73945), tendamistate, AI-3688, testratin, pradimicin-Q, and salbostatin.

The combination of acarbose, miglitol, emiglitate, or voglibose and one of the above-mentioned compounds of general formula (IB) according to the invention is preferred.

CETP Inhibition Test

1. Obtaining CETP

CETP was obtained in partially purified form from human plasma by differential centrifugation and column chromatography and was used for testing. In so doing, human plasma was adjusted with NaBr to a density of 1.21 g/ml and was centrifuged for 18 h at 50,000 rpm at 4° C. The bottom fraction (d>1.21 g/ml) was applied to a Sephadex® Phenyl-Sepharose 4B (Pharmacia) column, washed with 0.15 m NaCl/0.001 m Tris HCl, pH 7.4, and then eluted with dist. water. The CETP-active fractions were pooled, dialyzed against 50 mM Na acetate, pH 4.5, and applied to a CM-Sepharose® (Pharmacia) column. They were then eluted with a linear gradient (0-1 M NaCl). The pooled CETP fractions were dialyzed against 10 mM Tris HCl, pH 7.4, and were then further purified by chromatography over a Mono Q® column (Pharmacia).

2. Obtaining Radioactively-Labeled HDL

50 ml of fresh human EDTA plasma was adjusted with NaBr to a density of 1.12 and centrifuged at 4° C. for 18 h at 50,000 rpm in the Ty 65 rotor. The upper phase was used to obtain cold LDL. The lower phase was dialyzed against 3-4 l PDB buffer (10 mM Tris/HCl, pH 7.4, 0.15 mM NaCl, 1 mM EDTA, 0.02% NaN

3

). 20 μl of 3H cholesterol (Du Pont NET-725; 1 -μC/μl dissolved in ethanol) was subsequently added per 10 ml of dialysis residue volume and incubated for 72 h at 37° C. under N

2

.

The sediment was then adjusted with NaBr to a density of 1.21 and centrifuged in the Ty 65 rotor for 18 h at 50,000 rpm at 20° C. The upper phase was obtained, and the lipoprotein fractions were purified by gradient centrifugation. In so doing, the isolated, tagged lipoprotein fraction was adjusted with NaBr to a density of 1.26. Every 4 ml of this solution was covered in centrifuge tubes (SW 40 rotor) with 4 ml of a solution with a density of 1.21 and 4.5 ml of a solution with a density of 1.063 (density solutions from PDB buffer and NaBr) and then centrifuged for 24 h at 38,000 rpm and 20° C. in the SW 40 rotor. The intermediate layer between the density of 1.063 and 1.21 that contained the labeled HDL was dialyzed against 3×100 volumes of PDB buffer at 4° C.

The dialysis residue contained radioactively-labeled

3

H-CE-HDL, which was adjusted to approx. 5×10

6

cmp per ml and used for the test.

3. Conducting the Test

In order to test the CETP activity, the transfer of

3

H cholesterol ester from human HD lipoproteins to biotinylated LD lipoproteins was measured.

The reaction was ended by adding Streptavidin-SPA® beads (Amersham), and the transferred radioactivity was determined directly in the liquid scintillation counter.

In the test batch, 10 μl of HDL-

3

H cholesterol ester (˜50,000 cpm) was incubated for 18 h at 37° C. with 10 μd of biotin-LDL (Amersham) in 50 mM HEPES/0.15 m NaCl/0.1% bovine serum albumin/0.05% NaN

3

, pH 7.4, with 10 μl of CETP (1 mg/ml) and 3 μl solution of the substance to be tested (dissolved in 10% DMSO/1% BSA). Then, 200 μl of the SPA-Streptavidin bead solution (Amersham TRKQ 7005) was added, and the mixture was further incubated for 1 h under agitation and subsequently measured in the scintillation counter. Corresponding incubations with 10 μl buffer, 10 μl CETP at 4° C., and 10 μl CETP at 37° C. served as controls.

The transferred activity in the control batches with CETP at 37° C. was assessed as 100% transfer. The substance concentration in which this transfer was reduced by half was indicated as the IC

50

value.

Syrian golden hamsters from the company's own breeding were anesthetized after fasting for 24 h (0.88 mg/kg atropine, 0.80 mg/kg Ketavet® s.c., 30′ later 50 mg/kg Nembutal i.p.). The jugular vein was then exposed and cannulated. The test substance was dissolved in a suitable solvent (as a rule, Adalat placebo solution: 60 g glycerin, 100 ml H

2

O, ad 100 ml PEG-400) and administered to the animals via a PE catheter inserted into the jugular vein. The control animals received the same volume of solvent without any test substance. The vein was then ligated and the wound closed up. At different intervals—up to 24 h after administration of the test substance blood was drawn from the animals by puncture of the retroorbital venous plexus (approx. 250 μl). Coagulation was completed by incubating at 4° C. overnight, and the blood was then centrifuged for 10 minutes at 6,000 g. The cholesterol and triglyceride content in the serum obtained in this manner was determined using modified commercially-available enzyme tests (cholesterol enzymatic 14366 Merck, triglyceride 14364 Merck). The serum was diluted in a suitable manner with physiological saline solution. 100 μl serum dilution was mixed with 100 μl of test substance in 96well plates and incubated for 10 minutes at room temperature. The optical density was then determined with an automatic plate reader at a wavelength of 492 nm (SLT-Spectra). The triglyceride/cholesterol concentration contained in the samples was determined using a parallel-measured standard curve.

The determination of the HDL cholesterol content was carried out after precipitation of the lipoproteins containing Apo B by means of a reagent mixture (Sigma 352-4 HDL cholesterol reagent) according to the manufacturer's instructions.

In attempting to determine oral efficacy, the test substance, which was dissolved in DMSO and suspended in 0.5% methylcellulose, was administered orally to Syrian golden hamsters from the company's own breeding via a pharyngeal tube. The control animals received identical volumes of solvent without any test substance. Feed was then withheld from the animals, and blood was drawn at different intervals—up to 24 h after administration of the substance—via puncture of the retroorbital venous plexus. Further processing was carried out as described above.

The new active compounds can be converted in a known manner into the customary formulations, such as tablets, coated tablets, pills, granules, aerosols, syrups, emulsions, suspensions, and solutions, using inert, nontoxic, pharmaceutically-suitable excipients or solvents. In this connection, the therapeutically-active compound should be present in each case in a concentration of about 0.5% to 90% by weight, i.e., in amounts that are sufficient to achieve the dosage range indicated.

The formulations are prepared, for example, by extending the active compounds using solvents and/or excipients, if appropriate using emulsifiers and/or dispersants, with it being possible, for example, in the case of the use of water as a diluent, to use organic solvents, if appropriate, as auxiliary solvents.

Administration takes place in a customary manner, preferably orally or parenterally, in particular, perlingually or intravenously.

In the case of parenteral use, solutions of the active compound can be employed using suitable liquid excipients.

In general, it has proved to be advantageous in intravenous administration to administer amounts of about 0.001 to 1 mg/kg, preferably about 0.01 to 0.5 mg/kg of body weight, to obtain effective results, and in oral administration, the dosage is about 0.01 to 20 mg/kg, preferably 0.1 to 10 mg/kg of body weight.

In spite of this, it may be necessary to deviate from the amounts mentioned, depending on the body weight or the type of administration route, individual response to the medication, the type of formulation thereof, and the time or interval at which administration takes place. Thus in some cases, it may be sufficient to manage with less than the minimum amount previously mentioned, whereas in other cases, the upper limit mentioned must be exceeded. If larger amounts are administered, it may be advisable to divide these into several individual doses over the day.

Basic compounds of the invention are generally isolated in the form of their pharmaceutically acceptable add addition salts derived using inorganic or organic acids. Examples of such materials are hydrochloric, nitric, sulfuric, phosphoric, formic, acetic, trifluoroacetic, propionic, maleic, succinic, and malonic acids. Compounds of the invention which contain an acidic functionality such as a carboxyl group can be isolated in the form of pharmaceutically acceptable addition salts derived using inorganic or organic bases. The salt forming ion derived from such bases can be a metal ion such as sodium, potassium, lithium, calcium, magnesium, etc., or an ion of an organic base, such as an ammonium or substituted ammonium ion derived from an amine. Examples of suitable amines for this purpose include ammonia, arylalkylamines such as dibenzylamine and N,N-dibenzylethylenediamine, lower alkylamines such as methylamine, t-butylamine, procaine, lower alkylpiperidines such as N-ethylpiperidine, cycloalkylamines such as cyclohexylamine or dicyclohexylamine, 1-adamantylamine, benzathine, or salts derived from amino acids such as arginine or lysine.

The present invention also encompasses pharmaceutically acceptable “prodrugs” of the compounds of formula (IC) which form such derivatives. These are typically acylated derivatives of alcohol-containing compounds of the invention, though other types of prodrugs are known. Preparation of such derivatives is within the skill of the art.

The inhibitors of the present invention are contemplated for use in veterinary and human applications. For such applications, the active agent(s) are employed in pharmaceutical compositions which comprise the active ingredient(s) plus a pharmaceutically acceptable carrier which contains one or more diluents, fillers, binders, or other excipients, depending on the administration mode and dosage form contemplated. Examples of such agents include carriers such as sucrose, lactose, or starch; lubricating agents such as magnesium stearate; adjuvants, such as wetting agents; excipients such as cocoa butter or suppository wax; emulsifying and suspending agents, and sweetening, flavoring and perfuming agents and buffering agents.

The pharmaceutical compositions of the invention may also include one or more known antidiabetic agents in addition to a compound of structural formula (IC). Examples of such antidiabetic agents are: α-glucosidase inhibitors such as acarbose or voglibose, insulin sensitizers such as bromocriptine, thiazolidinediones such as troglitazone, insulin secretagogues such as glimepride, sulfonylureas such as glyburide, GLP-1 and its derivatives such as insulinotropin, amylin and its derivatives such as AC-137, calcitonin, insulin and its derivatives such as HOE-901, biguanides such as metformin, aldose reductase inhibitors such as tolrestat, β

3

agonists such as BTA-243, and hypocholesterolemics such as lovastatin.

The method of treating glucagon-mediated conditions by administering a glucagon receptor antagonist of the present invention may be practiced in mammals, including humans, which exhibit such conditions. A typical application is treatment of diabetes.

The compounds of this invention can be administered by oral, parenteral (e.g., intramuscular, intraperitoneal, intravenous or subcutaneous injection or implant), nasal, vaginal, rectal, sublingual, or topical routes of administration and can be formulated in dosage forms appropriate for each route of administration.

Solid dosage forms for oral administration include capsules, tablets, pills, powders and granules. In such solid dosage forms, the active compound is admixed with at least one inert pharmaceutically acceptable carrier such as sucrose, lactose, or starch. Such dosage forms can also comprise, as is normal practice, additional substances other than inert diluents, e.g., lubricating agents such as magnesium stearate. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. Tablets and pills can additionally be prepared with enteric coatings such as the OROS-CT/Osmet™ and PULSINCAP™ systems from ALZA and Scherer Drug Delivery Systems.

Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, the elixirs containing inert diluents commonly used in the art, such as water. Besides such inert diluents, compositions can also include adjuvants, such as wetting agents, emulsifying and suspending agents, and sweetening, flavoring and perfuming agents.

Preparations according to this invention for parenteral administration include sterile aqueous or non-aqueous solutions, suspensions, or emulsions. Examples of non-aqueous solvents or vehicles are propylene glycol, polyethylene glycol, vegetable oils, such as olive oil and corn oil, gelatin, and injectable organic esters such as ethyl oleate. Such dosage forms may also contain adjuvants such as preserving, wetting, emulsifying, and dispersing agents. Alternatively intramuscular, intraarticular or subcutaneous depot injection with or without encapsulation of the drug into degradable microspheres e.g., comprising poly(DL-lactide-co-glycolide) may be used to obtain prolonged sustained drug release. For improved convenience of the dosage form it may be possible to use an i.p. implanted reservoir and septum such as the Percuseal system available from Pharmacia. Improved convenience and patient compliance may also be achieved by the use of either injector pens (e.g. the NovoPen or Spen) or needle-free jet injectors (e.g. from Bioject, Mediject or Becton Dickinson). Prolonged zero-order or other precisely controlled release such as pulsatile release can also be achieved as needed using implantable pumps with delivery of the drug through a cannula into the synovial spaces. Examples include the subcutaneously implanted osmotic pumps available from ALZA, such as the ALZET osmotic pump.

Compositions for nasal or sublingual administration are also prepared with standard excipients well known in the art.

Compositions for rectal or vaginal administration are preferably suppositories which may contain, in addition to the active substance, excipients such as cocoa butter or a suppository wax.

The compounds of this invention can be manufactured into the above listed formulations by the addition of various therapeutically inert, inorganic or organic carriers well known to those skilled in the art. Examples of these include, but are not limited to, lactose, corn starch or derivatives thereof, talc, vegetable oils, waxes, fats, polyols such as polyethylene glycol, water, saccharose, alcohols, glycerin and the like. The formulations may be sterilized by, for example, filtration through a bacteria-retaining filter, by incorporating sterilizing agents into the compositions, by irradiating the compositions, or by heating the compositions. They can also be manufactured in the form of sterile solid compositions which can be dissolved in sterile water, or some other sterile injectable medium immediately before use. Various preservatives, emulsifiers, dispersants, flavorants, wetting agents, antioxidants, sweeteners, colorants, stabilizers, salts, buffers and the like are also added, as required to assist in the stabilization of the formulation or to assist in increasing bioavailability of the active ingredient(s) or to yield a formulation of acceptable flavor or odor in the case of oral dosing.

The amount of the pharmaceutical composition to be employed will depend on the recipient and the condition being treated. The requisite amount may be determined without undue experimentation by protocols known to those skilled in the art. Alternatively, the requisite amount may be calculated, based on a determination of the amount of target receptor which must be inhibited to treat the condition. An effective amount of active ingredient is generally in the range 0.0001 mg/kg to 100 mg/kg of body weight.

The treatment method of the invention is not limited to administration of the above-described pharmaceutical composition. Rather, this treatment regimen may be employed in combination with conventional treatments of diabetes (both Type I and Type II) or of other conditions which are sometimes found in diabetic subjects. Thus, for example, treatment may be administered in conjunction with (a) diet restrictions and exercise; (b) insulin, or other drugs used to treat ketoaddosis; (c) any drug used for the treatment of hyperlipidemia, such as lovastatin, or cardiovascular disease, such as enalapril; (d) drugs used to treat diabetic complications, such as epalrestat and (e) drugs that lower body weight, such as dexfenfluramine.

The glucagon receptor antagonists of the invention are useful not only for treatment of the pathophysiological conditions discussed above, but are also useful in other applications such as a diagnostic agent. For example, these compounds can be administered to humans in vivo in the fasting state as a diagnostic tool to directly determine whether the glucagon receptor is functional. Serum samples taken before and after such administration can be assayed for glucose levels; comparison of the amounts of blood glucose in each of these samples would be a means for directly determining the ability of the patient's glucagon receptor to modulate hepatic glucose output. Altematively, compounds of the present invention may be useful for finding new glucagon antagonists. For example, a binding assay employing a radiolabeled derivative (such as

3

H) of a compound of formula (IC) would be useful in identifyig new compounds that competitively bind to the glucagon receptor. Such an assay is useful in identifying structurally novel antagonists that may offer advantages in ease of chemical modification, selectivity and oral bioavailability.

The compounds of the present invention may contain asymmetric centers on the molecule, depending upon the nature of the various substituents. Each such asymmetric center will produce two optical isomers. In certain instances, asymmetry may also be present due to restricted rotation about the central bond adjoining the two aromatic rings of the specified compounds. For example, for certain compounds of Formula (IC) wherein Ar is taken as substituted phenyl, there exist additional isomers due to restricted rotation about the central aryl-aryl bond, depending on the substitution pattern.

It is intended that all isomers, either by nature of asymmetric centers or by restricted rotation as described above, as separated, pure or partially purified isomers or racemic mixtures thereof, be included within the ambit of the instant invention. In the case of compounds of Formula (IC) wherein R

3

is taken as 1-hydroxyethyl, it has been found that the isomer in which the hydroxy substituent is above the plane of the structure, as seen in Formula Ic, is more active and thus more preferred over the compound in which the hydroxy substituent is below the plane of the structure.

Representative examples of the nomenclature employed herein are given below:

2,6-Dimethyl-3-hydroxymethyl-4-(3-bromophenyl)-5-isobutylpyridine

3,5Di-t-butyl-2-(phenylthio)methyl-6-hydroxymethyl-3′,5′-dichloro-1,1′-biphenyl

The compounds of general formula (IC) of the present invention are prepared as indicated in the following reaction Schemes.

The phenylpyridine compounds of formula (IC) (X=N) are prepared from a common intermediate 6 using the well-known Hantzsch pyridine synthesis, as shown in Scheme 1 (Stout, D. M.; Myers, A. I.

Chem. Rev.

1982,223).

The ketoester 1, (commercially available or prepared according to the procedure of Deslongchamps,

Synth. Comm.,

1976, 6, 169) is treated with an ammonium salt such as ammonium acetate, in an inert solvent such as cyclohexane capable of forming an azeotrope with water, to give the enamine 2. Compound 2 is then treated with the ketoester 3. which may or may not be identical to the ketoester 1, and an aromatic aldehyde, in a polar solvent such as ethanol, to produce the dihydropyridine 5. Certain substituents on aldehyde 4 may need to be protected during the Hantzsch pyridine synthesis. A description of suitable protecting groups may be found in:

Protective Groups in Organic Synthesis

, Second Edition, T. W. Greene, John Wiley and Sons, New York, 1991. Oxidation of 5 is achieved by any of several known methods. For example, treatment of 5 with 2,3-dichloro-5,6dicyanobenzoquinone (DDQ) in a solvent such as methylene chloride (CH

2

Cl

2

), or with ceric ammonium nitrate (CAN) in a mixture of solvents such as aqueous acetone, affords the intermediate 6. Separation of unwanted side products and purification of intermediates is achieved by chromatography on silica gel, employing flash chromatography (Still, W. C.; Khan, M.; Mitra, A.

J. Org. Chem.,

1978, 43, 2923)

An alternative Hantzsch pyridine synthesis of the intermediate

6

where R

1a

and R

1b

of formula (IC) are identical, can be accomplished following the procedure of Chucholowski (U.S. Pat. No. 4,950,675), Scheme 2. By heating two equivalents of ketoester 1 with ammonium hydroxide and the aldehyde 4 in a polar solvent such as methanol, the dihydropyridine 5 is obtained directly. Compound 5 is oxidized to pyridine 6, according to the procedure described in Scheme 1.

In Scheme 3, another alternative Hantzsch pyridine synthesis of intermediate 6 is described. Ketoester 1 is condensed with aldehyde 4 by treatment with catalysts such as acetic acid and piperidine without solvent to afford intermediate 7. Treatment of 7 with ketoester 3 in the presence of a base such as sodium methoxyde, in a polar solvent such as methanol produces the diketone 8. Cyclization of 8 is achieved by treatment with an ammonium salt such as ammonium acetate in a polar solvent such as acetic add to afford the previously described dihydropyridine 5 (Scheme 1), which is oxidized to the pyridine 6 according to the procedure as indicated in Scheme 1.

The synthesis of aryl pyridine derivatives of formula (IC) wherein R

2

is alkyl and R

3

is hydroxymethyl (IIa) is described in Scheme 4.

Chemical reducing agents such as sodium bis(2-methoxyethoxy)aluminum hydride (Red-Al) in an inert solvent, such as tetrahydrofuran (THF) or diethyl ether (Et

2

O), can result in a monoreduction of the pyridinediester 6 to give the alcohol 9. Oxidants such as pyridinium chlorochromate (PCC), in a solvent such as CH

2

Cl

2

, convert compound 9 to the aldehyde 10. Wittig reaction with compound 10 and an ylide 11a in an inert solvent such as THF or Et

2

O, affords olefin 12 obtained usually, but not always, as a mixture of E and Z isomers . The reagent 11a is prepared from an alkyl triphenyl phosphonium salt, wherein the alkyl group may contain a heteroatom, and a suitable base such as butyllithium or sodium amide, according to known methods (Maercker, A. in

Organic Reactions

, Vol. 14, Ed.; Wiley, New York, 1965, Chapter 3). Olefin 12 is successively treated with a reducing agent such as lithium aluminum hydride (LAH), in an inert solvent such as THF or Et

2

O, and hydrogen in the presence of a metal catalyst, such as palladium on carbon, in a polar solvent such as ethanol, to afford compounds of formula IIa. In some of these compounds, R

2

may contain substituents such as alcohol, acetate, ester, carboxylic add, and amide. These products can be obtained directly by the procedures of Scheme 4, with or without the use of appropriate protecting groups, or by additional steps familiar to those skilled in the art. For example, a primary alcohol can be converted to a carboxylic acid by standard methods of oxidation, such as those described by Eisenbraun (Eisenbraun, E. J.

Org. Syn. Coll.,

1973, 5, 310).

If the Wittig reaction is performed with methoxymethyl triphenyl-phosphonium as ylide (11b), followed by treatment with an add such as hydrochloric add, the homologous aldehyde 13 is obtained. This can undergo another Wittig reaction to afford olefin 14, (Scheme 5). This known procedure (Wittg, G.; Walter, B.; Kruck, K.-H. Chem. Ber. 1962, 2514) allows one to synthesize extended alkyl chain (R

2

) analogs of formula IIa, which may not be directly prepared by usual Wittig reaction due to limited availability of the requisite alkyl triphenylphosphonium salt.

Oxidation of the compounds of formula IIa by the method described in Scheme 4 affords intermediates that can be converted to homologues of compounds of formula IIa, containing the —CH

2

—CH

2

— linkage between the pyridine nucleus and the hydroxy group (IIb).

Synthesis of aryl pyridine derivatives of formula (IC) wherein R

2

is alkyl containing a heteroatom such as sulfur and R

3

is hydroxymethyl (IIa and IIIb), is outlined in Scheme 6. Alcohol 9 is converted to an alkyl halide 15 by treatment with a suitable reagent such as dibromotriphenylphosphorane in an inert solvent. Treatment of 15 with a thiol and a base such as N-methyl morpholine in an inert solvent produces intermediate 16. The sulfur atom of compounds 16 can be oxidized (n=1 or 2) by any of several known methods. For example, it can be accomplished by treatment of 16 wherein n=0, with an oxidant such as m-chloroperbenzoic acid in a solvent such as CH

2

Cl

2

. Chemical reducing agents such as lithium aluminum hydride (LAH) in an inert solvent such as tetrahydrofuran or diethyl ether, can reduce the ester 16 to a compound of formula IIIa. Intermediate 15 can also react with alcohols following the methods outlined in Scheme 6, to afford compounds of formula IIIc.

The synthesis of aryl pyridine derivatives of formula (IC) wherein R

2

is alkyl containing a heteroatom such as nitrogen and R

3

is hydroxymethyl (IVa), is outlined in Scheme 7. Treatment of 15 with a primary or secondary amine in an inert solvent results in the intermediate 17. Chemical reducing agents such as lithium aluminum hydride in an inert solvent, such as tetrahydrofuran or diethyl ether, can reduce ester 17 to a compound of formula IVa. Reduction of aldehyde 13 by the method outlined in Scheme 4 affords an intermediate that can be converted to homologues of compounds of formula ma and IVa, containing the —CH

2

—CH

2

—linkage between the pyridine nucleus and the sulfur or nitrogen substituent (IIIb and IVb).

Synthesis of aryl pyridine derivatives of formula (IC) wherein R

2

is alkyl and R

3

is 1-hydroxyethyl (Va), is outlined in Scheme 8. Oxidants such as pyridinium chlorochromate (PCC), are used to convert compounds of formula II to the aldehyde 18. Treatment of 18 with an organometallic reagent such as methyl magnesium bromide or methyl lithium in an inert solvent such as THF or Et

2

O affords racemic compounds of formula Va. Chiral 1-hydroxyethyl aryl pyridine derivatives of formula Vb are obtained by resolution of the racemates Va by classical methods. For example, resolution can be achieved by formation of diastereomeric adducts of the racemic compounds with optically active reagents such as α-methoxy-α-(trifluoromethyl)phenylacetic acid (Dale, J. A.; Dull, D. L.; Mosher, H. S.

J. Org. Chem.

1969, 34, 2543). Alternatively, separation of enantiomers is achieved by HPLC on chiral solid phase. Determination of absolute stereochemistry can be achieved in a number of ways familiar to those skilled in the art, including X-ray analysis of a suitable crystalline derivative, such as a Mosher ester.

An alternative synthesis of aryl pyridine derivatives of formula Vb is achieved by treating aldehyde 18 with the anion of methyl toluylsulfoxide 19 to give a diastereomeric mixture of alcohols 20 as shown in Scheme 9 (B3lase, F. R.; Le H.

Tet. Lett.

1995, 36, 4559). The diastereomers are separated by flash chromatography and treated separately with Raney nickel and hydrogen in ethanol to provide pure enantiomers (>99% enantiomeric excess, e.e.) of the compounds of formula Vb. Alternatively, the chromatographic step is avoided by a two step sequence consisting of (1) oxidation of the mixture 20 with manganese dioxide in an inert solvent, followed by (2) reduction of the ketone with a chemical reductant such as LAH, to provide the enantiomerically pure alcohol 21. Treatment of 21 with Raney nickel and hydrogen in a polar solvent provides pure enantiomer (>99% e.e.) of the compounds of formula Vb.

A preferred alternative enantioselective synthesis of aryl pyridine derivatives of formula Vb is shown in Scheme 10. Treatment of the racemic mixture of compounds of formula Va with an oxidant such as pyridinium chlorochromate (PCC), gives the ketone 22. Reduction of 22 with a complex of LAH and N-mefflylephedrine (Kawasaki, M.; Susuki, Y.; Terashima, S.

Chem. Lett.

1984, 239) in an inert solvent, provides the alcohol of formula Vb with an enantiomeric excess of 95%.

The synthesis of aryl pyridine derivatives of formula (IC) wherein R

2

is alkyl and R

3

is 1,2-dihydroxyalkyl (VI), is described in Scheme 11. A methyl triphenylphosphonium salt is treated with a suitable base such as butyllithium in an inert solvent and reacted with intermediate 18 to afford olefin 23. Treatment of compound 23 with a suitable oxidant such as osmium tetroxide in a polar solvent such as pyridine gives the compounds of formula VI.

The synthesis of aryl pyridine derivatives of formula (IC) wherein R

2

and R

1b

are taken together to form an alkylene bridge and R

3

is hydroxymethyl (VIIa), 15 is described in Scheme 12. The ketoester 1 is treated with an aromatic aldehyde and catalysts such acetic acid and piperidine, in ethanol, to afford the α,β-unsaturated ketoester 24. Treatment of 24 with the cyclic ketone 25 and a base such as lithium bis(trimethylsilyl)amide in an inert solvent such as THF affords an intermediate which is treated with ammonium acetate and copper acetate in acetic acid to give the pyridine 26. Chemical reducing agents reduce the ester 26 to analogs of formula VIla. It may be appreciated that these analogs can be used as intermediates to generate new derivatives of formula (IC) wherein R

2

and R

1b

are taken together and R

3

is 1-hydroxyethyl (VIlb) according to the procedures described in Scheme 8.

The synthesis of the aryl pyridine derivative IIa wherein R

1b

is CH

2

OH is described in Scheme 13. Alcohol 27 (aryl pyridine IIa in which R

1b

is CH

3

) is treated with a trialkylsiyl chloride, such as tert-butyldiphenylsilyl chloride, and a base to yield silyl ether 28. Treatment of 28 with meta-chloroperbenzoic acid in an inert solvent, such as chloroform, provides the N-oxide 29. The N-oxide is treated with acetic anhydride to afford pyridine acetate 30. Treatment of 30 with aqueous methanol in the presence of potassium carbonate, yields alcohol 31. The silyl ether is cleaved with tetrabutylammonium fluoride in nHF to provide aryl pyridine derivative 32.

The synthesis of aryl pyridine derivatives Xa wherein R

1b

is —CH

2

NR

R

5

is described in Scheme 14. Oxddation of alcohol 31 as described in Scheme 4 yields aldehyde 33. Treatment of the aldehyde with an amine in the presence of a Lewis acid, such as zinc chloride, and a reducing agent, such as sodium cyanoborohydride, provides the amine 34. Deprotection of the alcohol as described in Scheme 13 affords aryl pyridine derivative Xa.

An alternative synthesis of amine 34 is shown in Scheme 15. Treatment of pyridine N-oxide 29 with phosphorus oxychloride and a base, such as triethylamine, in CH

2

Cl

2

, yields chloromethylpyridine 35. The chloride is treated with an amine providing amine 34.

The synthesis of aryl pyridine derivatives Xb wherein R

1b

is —CH═CHR is described in Scheme 16. Alcohol 31 is converted to the corresponding bromide as described in Scheme 6. Treatment of 36 with sodium phosphite in benzene yields phosphonate 37. The phosphonate is treated with a base, such as sodium hydride, and subsequently with an aldehyde affording olefin 38. Deprotection of the alcohol as described affords aryl pyridine Xb.

An alternative synthesis of olefin 38 is shown in Scheme 17. Aldehyde 33 is treated with an ylide as described in Scheme 4 to yield olefin 38.

The synthesis of aryl pyridine derivative Xc wherein R

1b

is —CH

CH

2

R is described in Scheme 18. Hydrogenation of olefin Xb as described in Scheme 4 yields the alkane Xc.

The synthesis of aryl pyridine derivative Xd wherein R

is —CH(OH)R is described in Scheme 19. Treatment of aldehyde 33 with a Grignard reagent in an inert solvent, such as THF, yields alcohol 39. Deprotection of the alcohol as described affords aryl pyridine derivative Xd.

The synthesis of aryl pyridine derivatives Xe wherein R

1b

is —COR is described in Scheme 20. Oxddation of alcohol 39 as described in Scheme 4 yields ketone 40. Deprotection of the alcohol as described affords the aryl pyridine derivative Xe.

The synthesis of aryl pyridine derivatives Xf wherein R

1b

is —C(OH)RR′ is described in Scheme 21. Grignard addition to ketone 40 as described in Scheme 19 yields alcohol 41. Deprotection of the alcohol as described affords the aryl pyridine derivative Xf.

The synthesis of aryl pyridine derivatives Xg wherein R

1b

is —C(OR

4

)RR′ is described in Scheme 22. Treatment of alcohol 41 with a base, such as sodium hydride, and an alkylating agent in THF, yields ether 42. Deprotection of the alcohol as described affords the aryl pyridine derivative Xg.

The biphenyl analogs described in formula (IC) (X=C—R

8

, wherein R

8

is H), are prepared by the methods described by Fey, et al. US Patent 5,138,090. The key step of the synthesis is the coupling of an arylpalladium dimer with an aryl Grignard reagent (Scheme 23).

A specific example of this method is shown in Scheme 24. Treatment of diol 43 (prepared according to the procedure of Fey, et al. U.S. Pat. No. 5,138,090) with (2-methoxy)ethoxymethyl chloride and diisopropylethylamine in CH

2

Cl

2

solvent gives MEM ether 44. Oxidation of the remaining alcohol of 44 as described in Scheme 4 provides aldehyde 45. Treatment of the aldehyde with aniline in the presence of a catalytic amount of p-toluenesulfonic acid (pTSA) and molecular sieves in toluene solvent gives imine 46. The imine is converted to the palladium dimer 47 upon treatment with palladium acetate in acetic acid solvent. Treatment of 47 with triphenylphosphine, then with 4-fluorophenylmagnesium bromide (prepared from 1-bromo4-fluorobenzene and magnesium metal), and finally with aqueous hydrochloric acid in benzene solvent yields biphenyl 48. The aldehyde moiety of biphenyl 48 is converted to a pentyl group by the methods described in Scheme 4. MEM ether 50 is treated with trimethylsilyl chloride and sodium iodide in acetonitrile solvent, and subsequently with sodium acetate in DMF solvent to provide acetate 51. Saponification of the acetate using potassium hydroxide in methanol solvent provides alcohol 52. Hydroxymethyl biphenyl 52 is transformed to racemic hydroxyethyl biphenyl 54 as described in Scheme 8.

An alternative synthesis of biphenyls of formula (IC) is the coupling of a suitably functionalized benzene derivative 57 (where X can be trifluoromethanesulfonate, methoxy, bromide, or iodide) with an arylmetal reagent ArMY

n

(where M may be B, Sn, or Mg, and Y is a ligand).

An example of such a biaryl coupling is the Suzuki reaction (Myaura, N., Yanagi, T., Suzuki, A.

Synth. Comm.

1981, 11, 513-519; Oh-e, T., Miyaura, N., Suzuki, A.

J. Org. Chem.

1993, 58, 2201-2208) in which a benzene derivative 58 (in which X can be trifluoromethanesulfonate, bromide, or iodide) is coupled with an arylboronic acid (Scheme 26).

The requisite arylboronic acid 60 may be prepared by sequential reaction of an aryl halide 59 (X=Br or I) with magnesium metal, a boronic ester, and hydrochloric acid.

A specific example of the use of the Suzuki reaction to synthesize a biphenyl analog is depicted in Scheme 28. Phenol 61 is treated sequentially with sodium hydride and allyl bromide in dimethylformamide solvent to afford allyl ether 62. Claisen rearrangement of the ether provides phenol 63. The phenol is treated with trifluoromethanesulfonic anhydride (triflic anhydride) and pyridine in CH

2

Cl

2

solvent to give triflate 64. Treatment with 4fluorophenylboronic acid, tetrakistriphenylphosphine palladium (0), potassium phosphate (tribasic), and potassium bromide in 1,4dioxane solvent affords biphenyl 65. Catalytic hydrogenation as described in Scheme 4, and reduction of the ketone with lithium aluminum hydride in THF solvent provides the desired biphenyl analog 67.

An alternative synthesis of biphenyls of type I uses a cycloaromatization of a ketodiester 68 with a diketone in the presence of a catalytic amount of sodium methoxide in methanol solvent to give a phenol 69. The phenol is then coupled with an arylboronic acid as described in Scheme 28 to afford biphenyl diester 70. The diester is then transformed as described in Schemes 4, 8, and 10 to give the analog with the desired R

2

and R

3

groups.

An alternative method of transforming phenol 69 to biphenyl 70 is shown in Scheme 30. Treatment of the phenol with dimethylsulfate and a base such as potassium carbonate yields the methyl ether 71. The ether is treated with an aryl Grignard reagent to afford biphenyl 70.

The diester 70 can be further transformed by an alternative method shown in Scheme 31, to give the analogs with the desired R

2

and R

3

groups. Chemical reducing agents such as sodium bis-(2-methoxyethoxy)-aluminum hydride (Red-Al), can result in a mono reduction of the diester 70 to give the alcohol 72. Alcohol 72 can be attached to a polymeric support such as Wang resin, by treatment with a base such as sodium hydride in DMF, to give the intermediate 73. The ester group of intermediate 73 can be transformed to an alkyl halide in a two step process; 73 is treated with a reducing agent such as LAH, then Phosphorous tribromide to afford compound 74. The allyl halide 74 is treated with an alkyl thiol and a base such as N-methyl morpholine, then by TFA to cleave the ether linkage with the polymeric resin, to afford the alcohol 75.

It will be appreciated that synthesis of some compounds of formula (IC) may require use of protecting groups at various stages of the procedures. These are removed in subsequent steps. For example, the removal of O-benzyl ether protecting groups is carried out by treatment with hydrogen in the presence of a metal catalyst, such as palladium on carbon, in a polar solvent such as ethanol. The removal of silyl ether protecting groups is carried out by treatment with fluoride salts, such as tetrabutylamonium fluoride in a solvent such as THF. Conditions required to remove other protecting groups which may be present can be found in:

The order of carrying out the steps of the foregoing reaction schemes is not always significant, and it is within the skill of the art to vary the order of reactions to facilitate the reaction or to avoid unwanted reaction products.

The following examples are provided for the purpose of further illustration only and are not intended to limit the disclosed invention.

EXAMPLE 1

2,6-Diisopropyl-3-hydroxymethyl-4-(4-fluorophenyl)-5-pentylpyridine

Step A: 3-Amino-4-methyl-2-pentenoic acid, ethyl ester

To 100 g (0.63 mol) of ethyl isobutyryl acetate was added ammonium acetate (68.2 g, 0.89 mol), cyclohexane (230 mL) and isopropanol (74 mL). The mixture was heated at reflux under argon atmosphere with a Dean-Stark trap. After 2 hours, a second portion of ammonium acetate (14.6 g, 0.19 mol) was added to the reaction. The reaction was heated at reflux for 12 hours and then allowed to cool to room temperature. A total of ˜30 mL of water was collected in the Dean-Stark trap. An ice bath was used to cool the reaction to 10° C. and then ammonium hydroxide (63 mL) was added dropwise. The organic layer was separated, dried with sodium sulfate, filtered, and concentrated to yield a yellow oil. The crude product (90.9 g, 0.58 mol, 92%) was taken directly to the next step without any further purification.

Step B: Diethyl 1,4-dihydro-2,6-diisopropyl-4-(4-fluorophenyl)-3,5-pyridinedicarboxylate

To an oven-dried 250 mL three-neck round bottom flask equipped with a thermometer were added copper(l) iodide (3.21 g, 16.9 mmol) and toluene (40 mL) under an argon atmosphere. The slurry was cooled to an internal temperature of 0° C . Methyllithium (1.4M in ether, 25 mL, 0.03314 mol) was added at a rate to maintain reaction temperature <5° C. The reaction was then allowed to stir at 0° C. for 50 min. At the end of this time the intermediate from Step B (1.33 g, 3.19 mmol) in 10 mL toluene was added via syringe at a rate to maintain reaction temperature <5° C. The syringe was rinsed with an additional 4 mL toluene and this rinse was added to the reaction mixture at a rate to maintain reaction temperature <5° C. The reaction was stirred at 0° C. for 35 min. The reaction was then quenched by the addition of a saturated solution of ammonium chloride (20 mL) and was allowed to stir for 36 h at 25° C. The reaction mixture was poured into a separtory funnel and was extracted with ethyl acetate (3×50 mL). The combined organic layer was then concentrated to yield the crude intermediate (1.4 g, yellow oil, 9:1 ratio of diastereomers). The crude intermediate was dissolved in a mixture of ethanol (30 mL) and tetrahydrofuran (10 mL) under argon, treated with 10% palladium on carbon (140 mg), and was then stirred under a hydrogen atmosphere for 14 h. After purging the system with argon, the catalyst was removed by filtration through a pad of Celite. The solvent was removed and the residue was purified by flash chromatography (12-15% ethyl acetate-hexane) to yield 1.0 g of the title compound as two separate diastereomers.

The combined extracts were dried over magnesium sulfate and concentrated in vacuo to give a brown oil which was subjected to flash column chromatography on silica (80 mm×19.5″) using a stepwise gradient elution of dichloromethane:hexanes (1:3, 1:2, 1:1, 4L each). The fractions containing the product were combined and concentrated to afford an inseparable mixture of the product and an unidentified side product in about a 1:1 ratio as a pale yellow gum (5.3 g, 33% mass balance). This material was not fully characterized and was used without further purification.

Step F: Isopropyl 3,5-diisopropyl-6-hydroxymethyl-2′-benzyloxy-4′-fluoro-1,1′-biphenyl-2-carboxylate

A mixture of the intermediate from Step E (5.83 g, 10.9 mmol) and Red-Al (3.3 mL, 10.9 mmol) in dry tetrahydrofuran (100 mL) was held at reflux for 2.5 hours. Additional Red-Al was added (in 3.3 mL aliquots) and reflux maintained until the lower Rf spot disappeared (21 hours, total 8 eq. Red-Al; i.e. the by-product from the previous step reacted faster than the desired diester). The reaction mixture was cooled to 0° C., carefully quenched with water (14 mL), and vigorously stirred for 2 hours. The precipitated solids were removed via vacuum filtration through paper and the collected solids were washed with ethyl acetate (3×100 mL) and refiltered. The combined filtrates were washed with a 1:1 mixture of water and saturated aqueous sodium chloride (100 mL), followed by water (75 mL) and saturated aqueous sodium chloride (50 mL). The organic portion was separated, dried over sodium sulfate and concentrated in vacuo. Purification by flash column chromatography on silica (80 mm×6″) using hexanes:ethyl acetate (19:1) as eluent gave pure diisopropyl 3,diisopropyl-2′-benzyloxy-4′-fluoro-1,1′-biphenyl-2,6-dicarboxylate (2.63 g, 4.92 mmol). This was resubjected to the reaction conditions with Red-Al (2.95 mL, 9.84 mmol) in dry tetrahydrofuran (45 mL). Additional Red-Al was added (in 2.95 mL aliquots) and reflux maintained until the reaction was complete (30 hours, total 12 eq. Red-Al). Worked up as above and subjected crude product to flash column chromatography on silica (40 mm×7″) using hexanes:ethyl acetate (19:1) as eluent to provide the desired product as a translucent colorless oil (1.25 g, 55%).

EXAMPLE 255

3,5-Diisopropyl-2-(thiophenylmethyl)-6-(hydroxymethyl)-4′-fluoro-1,1′-biphenyl

A suspension of Wang-resin (100 g, 1.09 mmol/g hydroxylated) was suspended in 1 L of a solution of 4N HCl in dioxane and gently stirred at room temperature for two days. After filtration, the chlorinated resin was washed 6 times with each of the following solvents; dioxane, isopropanol and finally THF. The resin was then dried at 60° C overnight. From this resin, 2.5 g (2.2 mmol based on the chlorine content detected by elemental analysis) was suspended in DMF (25 mL) and stirred at room temperature for 5 minutes, then the DMF was decanted off for the addition of a solution of 3,5-diisopropyl-2-hydroxymethyl-6carboxymethyl-4′-fluoro-1,1′-biphenyl (Example 244, Step D) (1.13 g, 3.3 mmol) in DMF (25 mL), followed by a solution of sodium hydride (60% in mineral oil, 170 mg, 3.3 mmol) in DMF (12.5 mL). The suspension was stirred at room temperature for two days under an argon atmosphere. The suspension was then filtered and the resulting resin was successively washed 10 times with each of the following solvents; DMF, a mixture THF/water (1:1), THF and finally with CH

HPLC: The Retention times (R.T.) for the compounds shown in the above table of exemplary compounds 255-290 were measured in minutes according to one of the three methods described below:

(I) Hypersil BDS-C18, 5 μm, 125×2 mm/Hewlett Packard, Flow 0.5 mL, 0-13 min 30-90% C, 13-15 min 90% C, Solvent A: Water/0.1% TFA; Solvent B: Acetonitrile..

(II) Hypersil BDS-C18, 5 μm, 125×2 mm/Hewlett Packard, Flow 0.5 mL, 0-13 min 30-90% C, 13-25 min 90% C, Solvent A: Water/0.1% TFA; Solvent B: Acetonitrile.

(III) NPS ODS-1, 1.5 mm, 33×4.6 mm/Micra, Flow 1.0 mL, 0-8 min 15-70% C, Solvent A: Water/0.1% TFA; Solvent B: Acetonitrile.

The estimated purity numbers were determined by comparison of peak areas, not by reference to standards.

The pharmaceutical utility of compounds of this invention is indicated by the following assay for glucagon receptor activity.

The affinity for the glucagon receptor of compounds of the present invention is determined by the glucagon receptor binding assay. Membranes were prepared from Chinese Hamster Ovary cells expressing the glucagon receptor (CHO-HGR) by scraping the cells into hypotonic lysis buffer (10 mM Tris, pH 7.4, 2 mM EDTA, 5 mM MgCl

2

and 1 mM PMSF) and subjecting the material to Polytron homogenization. Nuclei were removed by a 15-min 800×g centrifugation step conducted at 4° C. Membranes containing the receptor were collected by centrifugation at 15,000×g for 15 min at 4° C. The membranes were washed once in lysis buffer and suspended in 0.25 M sucrose, 10 mM Tris, 5 mM EDTA, pH 7.4. The membranes were used in ligand binding studies as reported (Yoo-Warren, H., Willse, A. G., Hancock, N., Hull, J., McCaleb, M., and Livingston, J. Regulation of Rat Glucagon Receptor Expression.

Biochem. Biophysical Res. Commun.

1994, 205, 347-353). In brief, 10 ug of membrane protein was incubated in 130 μl of binding buffer that consisted of 20 mM Tris, pH 7A, 1 mM EDTA, 1 mg/ml BSA, and 1 mg/ml bacitracin. The membrane suspension was placed in each well of a 96-well filtration plate (glass fiber type C, Millipore). Twenty μl of test compound was added to each well to give final concentrations ranging from 2 nM to 20 μM. Following the addition of test compound, 50 μl of

125

I-glucagon (9 fmol) (NEN) was added to each well. Control wells contained membranes, 0.5% DMSO (solvent for test compounds), radiolabeled glucagon without and with excess native glucagon (1 μM) to establish nonspecific binding. The plates were incubated for 60 min at room temperature, and then filtered on a Mllipore vacuum apparatus. Following a wash step with ice-cold PBS/0.1% BSA, the filters were punched into test tubes, and the membrane bound radioactivity was determined. An IC

50

value (the concentration of test compound needed to reduce membrane binding of radiolabelled glucagon by 50%) was calculated for each compound. If 20 μM compound did not reduce glucagon binding by 50%, the % reduction at 20 μM was reported in place of an IC

50

value. The binding characteristics for compounds of this invention are shown in Table I(C).
