ANTI-
HYPERLIPOPROTETNEMIC AND ANTI-HYPERGLYCEMIC
AGENTS
Field This application relates to substituted biaryl compounds which inhibit cholesterol ester transfer proteins (CETPs), stimulate reverse cholesterol transport, and inhibit the action of glucagon.
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 US 169 857. In addition, the production of 7 4 -aryl-3-pyridyl)-3,5-dihydroxy-hept-6enoate 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 W, "7 WO 98/04528 PCT/US97/13248 0 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 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. 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.
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.
To increase insulin secretion.
16. To decrease glucose toxicity.
2 WO 98/04528 PCTIUS97/13248 0 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.
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 W09518153-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 3 iri~ WO 98/04528 PCT/US97/13248 0 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.

Compounds of the general formulas (IA) and (Ia) 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 mellitus.
Within the context of the invention, glucosidase and/or amylase inhibitors are, for example, acarbose, adiposine, voglibose, miglitol, emiglitate, MDL-25637, camiglibose (MDL-73945), tendamistat, AI-3688, testatin, pradimicin-Q, and salbostatin.
The combination of acarbose, miglitol, emiglitate, or voglibose and one of the above-mentioned compounds of the general formula (IA) according to the invention is preferred.
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 NaCI/0.001 m TrisHCI, pH 7.4, and then eluted with dist. water. The CETPactive 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 WO 98/04528 PCT/US97/13248 0 linear gradient (0-1 M NaC1). The pooled CETP fractions were dialyzed against mM TrisHC1, pH 7.4, and were then further purified by chromatography over a Mono Q® column (Pharmacia).
2. Obtaining Radioactively Tagged HDL 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 3x4 1 of PDB buffer (10 mM Tris/HC1, pH 7.4, 0.15 mM NaC1, 1 mM EDTA, 0.02% NaN 3 20 gl 3H cholesterol (Du Pont NET-725; 1 -pC/gl dissolved in ethanol) was subsequently added per 10 ml of dialysis residue volume and incubated for 72 h at 37C 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 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 0 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 3x100 volumes of PDB buffer at 4°C.
The dialysis residue contained radioactively tagged 3 H-CE-HDL, which was adjusted to approx. 5x10 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 pl HDL- 3 H cholesterol ester 50,000 cpm) was incubated for 18 h at 370C with 10 pt biotin-LDL (Amersham) in 50 mM HEPES 0.15 m NaCI 0.1% bovine serum albumin 0.05% NaN 3 pH 7.4, with 10 gl CETP (1 mg/ml) and 3 il solution of the substance to be tested (dissolved in 10% DMSO WO 98/04528 PCT/US97/13248 0 1% BSA). Then 200 pl 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 L1 buffer, 10 pl CETP at 4°C, and 10 1l 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 5 0 value.

7 0.6 24 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., later 50 mg/kg Nembutal The jugular vein was then exposed and cannilated. The test substance was dissolved in a suitable solvent (as a rule, Adalat placebo solution: 60 g glycerin, 100 ml H 2 0, 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 pl). Coagulation was completed by incubating at 4°C overnight, then the blood was centrifuged for 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 pl serum dilution was mixed with 100 pl 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.
c WO 98/04528 PCT/US97/13248 0 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, 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.
WO 98/04528 PCT/US97/13248 0 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.

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 HCI, 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® WO 98/04528 PCT/US97/13248 0 (Pharmacia) column. They were then eluted with a linear gradient (0-1 M NaCI). The pooled CETP fractions were dialyzed against 10 mM Tris HC1, pH 7.4, and were then further purified by chromatography over a Mono Q® column (Pharmacia).
2. Obtaining radioactively-labeled HDL 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 rotor. The upper phase was.used to obtain cold LDL. The lower phase was dialyzed against 3 x 4 1 PDB buffer (10 mM Tris/HC1, pH 7.4, 0.15 mM NaC1, 1 mM EDTA, 0.02% NaN 3 20 pl of 3H cholesterol (Du Pont NET-725; 1 -gC/pl 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 l: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 x 100 volumes of PDB buffer at 4'C.
The dialysis residue contained radioactively-labeled 3
H-CE-HDL,
which was adjusted to approx. 5 x 106 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 ito 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 gl of HDL- 3 H cholesterol ester (-50,000 cpm) was incubated for 18 h at 37°C with 10 l of biotin-LDL (Amersham) in 50 mM HEPES 0.15 m NaCI 0.1% bovine serum albumin 0.05% NaN 3 pH 7.4, with 10 pl of CETP (1 mg/ml) and 3 gl solution of the substance to be tested 67 WO 98/04528 PCT/US97/13248 0 (dissolved in 10% DMSO 1% BSA). Then, 200 gl 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 pl buffer, 10 l CETP at 4'C, and 10 il CETP at 37C 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 5 0 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., 50 mg/kg Nembutal 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 H20, 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 tl). 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 Pl serum dilution was mixed with 100 pl of test substance in 96-well 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 WO 98/04528 PCT/US97/13248 0 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, 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 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.

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, lubricating agents such as magnesium stearate. In the case of capsules, tablets and pills, the dosage forms T :Y~~-1-:11~1-lr1l_1 i jln;l\Llllli- it;Jin6 lu-ir Iri~";;~55;l;~~jlPfi~~xli irr WO 98/04528 PCT/US97/13248 0 may also comprise buffering agents. Tablets and pills can additionally be prepared with enteric coatings such as the OROS-CT/OsmetTM and PULSINCAPTM 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 comprising poly(DLlactide-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 the NovoPen or Q-pen) or needle-free jet injectors 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.
SCompositions for nasalor 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 139 WO 98/04528 PCT/US97/13248 0 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 diet restrictions and exercise; insulin, or other drugs used to treat ketoacidosis; (c) any drug used for the treatment of hyperlipidemia, such as lovastatin, or cardiovascular disease, such as enalapril; drugs used to treat diabetic complications, such as epalrestat and 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 WO 98/04528 PCTIUS97113248 0 modulate hepatic glucose output. Alternatively, 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 identifying 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.
WO 98/04528 PCT/US97/13248 0 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.

In the case of compounds of Formula (IC) wherein
R
3 is taken as 1hydroxyethyl, 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.

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 is achieved by any of several known methods. For example, treatment of 5 with 2,3-dichioro-5,6-dicynobenzoquinone (DDQ) in a solvent such as methylene chloride (CH2C1 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, Khan, Mitra, A. J. Org. Chem., 1978,43,2923) An alternative Hantzsch pyridine synthesis of the intermediate 6, where R la and Rib of formula (IC) are identical, can be accomplished following the procedure of Chucholowski Patent 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.

Oxidants such as pyridinium chlorochromate (PCC), in a solvent such as CH2C12, convert compound 9 to the aldehyde 10. Wittig reaction with compound 10 and an ylide a in an inert solvent such as THF or Et20, 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 Olefin 12 is successively treated with a reducing agent such as lithium aluminum hydride (LAH), in an inert solvent such as THF or 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

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, WO 98/04528 PCTIUS97/13248 0 such as those described by Eisenbraun (Eisenbraun, E. J. Org. Syn. Coll., 1973, 310).
If the Wittig reaction is performed with methoxymethyl triphenylphosphonium as ylide (lib), followed by treatment with an acid such as hydrochloric acid, the homologous aldehyde 13 is obtained. This can undergo another Wittig reaction to afford olefin 14, (Scheme This known procedure (Wittg, Walter, Kruck, Chem. Ber. 1962, 2514) allows one to synthesize extended alkyl chain (R 2 analogs of formula Ia, 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 Ia, containing the -CH2-CH2- linkage between the pyridine nucleus and the hydroxy group (IIb).

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: Protective Groups in Organic Synthesis, Second Edition, T. W. Greene, John Wiley and Sons, New York, 1991.

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 MgC2 and 1 mM PMSF) and subjecting the material to Polytron homogenization. Nuclei were removed by a 15-min 800 x g centrifugation step conducted at 4 0 C. Membranes containing the receptor were collected by centrifugation at 15,000 x g for 15 min at 4 0 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, Hancock, Hull, McCaleb, 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 gl of binding buffer that consisted of 20 mM Tris, pH 7.4, l1mM EDTA, 1 mg/ml BSA, and 1 mg/mlbacitracin. The membrane suspension was placed in each well of a 96-well filtration plate (glass fiber type C, Millipore). Twenty pl of test compound was added to each well to give final concentrations ranging from 2 nM to 20 pM.
Following the addition of test compound, '50 pl of 1 2 5 I-glucagon (9 fmol) (NEN) was added to each well. Control wells contained membraies, 0.5% DMSO (solvent for test compounds), radiolabeled glucagon. without and with excess native glucagon (1 pM) to establish nonspecific binding. The plates were incubated for min at room temperature, and then filtered on a Millipore 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 IC50 value (the concentration of test compound needed to reduce membrane binding of radiolabelled glucagon by 50%) was calculated for each compound. If 20 gM 375 WO 98/04528 WO 9804528PCT/US97/13248 o compound did not reduce glucagon binding by 50%, the reduction at 20 jiM was reported in place of an IC50 value. The binding characteristics for compounds -of this invention are shown in Table I(C).
