Description: INSULIN RECEPTOR ACTIVATORS FOR THE TREATMENT OF METABOLIC DISORDERS IN HUMANS RESULTING FROM TREATMENT OF HIV INFECTION WITH HTV PROTEASE INHIBITORS BACKGROUND OF THE INVENTION (a) Field of the Invention The present invention relates to methods, chemical compounds, and compositions for the treatment of diseases induced by the use of an HIV protease inhibitor. In particular, this invention relates to methods, compounds, and compositions for the treatment of metabolic disorders induced by HTV protease inhibitors. (b) Description of Related Art Treatments for HIV infection have proven very effective in controlling the ravages of the terminal stage of the infection, AIDS. The HTV protease inhibitors are an extremely important component in the drug regimens used to suppress viral load and the resulting AIDS symptoms. Unfortunately, these drugs which are required to maintain health in HlV-infected individuals also carry a significant side-effect burden. One of the recently recognized severe side-effects is HIV protease inhibitor-induced insulin resistance leading to hyperglycemia that can progress to diabetes and ultimately life threatening ketoacidosis. (Carr, A., Samaras, K., Chrisholm, D.J., and Cooper, D.A. (1998) Lancet 351 1881-1883; Carr, A., Samaras, K., Burton, S., Freund, I., Chisholm, D J., Cooper D.A. (1998) AIDS 12, F51-F58). In addition to insulin resistance, other related disturbances in metabolism, such as lipodystrophy and hypertriglyceridemia, are also observed in HIV protease inhibitor treated patients (Roth, V.R., Kravcik, S., Angel, J.B. (1998) Clin Infect Dis 27,65-67; Safrin, S., and Grunfeld, C, (1999) AIDS 13, 2493-2505; Carr, A., Samaras, K., Thorisdottir, A., Kaufmann, G.R., Chrisholm, D.J., and Cooper, D.A. (1999) Lancet 353, 2093-2099; Behrens, G., Dejam, A., Schmidt, H., Balks, H-J., Brabant, G., Korner, T., Stoll, M., and Schmidt, R.E. (1999) AIDS 13, F63-F70). This complex metabolic side-effect profile of these very important drugs has all the hallmark features of the insulin-resistant state referred to as Syndrome-X (Reaven, G.M. (1993) Annu. Rev. Med. 44, 121-131). For some patients, these metabolic side-effects greatly limit the use of these life- sustaining drugs. This side-effect profile was not recognized early in the development of these drugs, but once these inhibitors entered general clinical use, this problematic side- effect manifested itself in a large percentage of the treated population. The problem appears to be a class effect in that all the currently available HIV protease inhibitor drugs demonstrate this severe effect. The molecular origin of this phenomena was recently identified in 3T3 Ll adipocytes (Murata, H., Hruz, P.W., and Mueckler, M. (2000) The Journal of Biological Chemistry 275:27, 20251-20254). The report provided evidence that at least three of the commercialized HIV protease inhibitor drugs also inhibit the glucose transporter from localizing to the cell membrane with the subsequent inhibition of glucose uptake by these cells. This inhibition of cellular glucose transport into cells by these HIV protease inhibitors is consistent with the elevation of glucose and lipids observed in the clinic for some patients being treated with these protease inhibitor drugs. Insulin receptor activators are known to stimulate the translocation of the glucose transporter to the cell membrane and so to stimulate the subsequent uptake of extracellular glucose. Several classes of compounds are known to act as insulin receptor activators. Insulin receptor activators include compounds of the structural classes Formulas I through VII illustrated below. Examples of compounds of formula I-H are described in WO 00/71506 and WO 01/12591. Syntheses of compounds of Formulae III and IV are described in the "Examples" section, below. Examples of compounds of Formulas V and VI are reported in U.S. Patent No. 6,051,597, and WO 99/51225, and examples of compounds of Formula VII have been reported in U.S. Patent Nos. 5,851,988 and 5,830,918. In addition, azo dye-like compounds have been reported by Geier et al. (U.S. Patent No. 6,020,374). BRIEF SUMMARY OF THE INVENTION This invention relates to the use of insulin receptor-activating compounds for the treatment of diseases induced by the use of an HIV protease inhibitor. In particular, this invention discloses the use of insulin receptor-activating compounds for the treatment of HIN protease inhibitor-induced insulin resistance, hyperglycemia, diabetes, ketoacidosis, lipodystrophy, and hypertriglyceridemia in humans. These insulin receptor-activating compounds may also be used in conjunction with insulin for the treatment of diseases related to the use of HIV protease inhibitors, such as HIV protease inhibitor-induced insulin resistance, hyperglycemia, diabetes, ketoacidosis, lipodystrophy and hypertriglyceridemia in humans. Applicants have discovered that compounds which sensitize the insulin receptor reverse the HIN protease inhibitor side-effect of metabolic disorders such as those listed above. Applicants have discovered that compounds that are insulin receptor activators can reverse the glucose uptake inhibition caused by HIN protease inhibitor drugs. Thus, applicants herein disclose that compounds which enhance glucose transport into cells treated with HIN protease inhibitors can provide relief from this therapy-limiting side- effect seen in protease inhibitor-treated patients. Insulin receptor activator compounds as herein disclosed can provide an effective therapy to HIV protease inhibitor-induced insulin resistance, hyperglycemia, diabetes, ketoacidosis, lipodystrophy and hypertriglyceridemia. The present invention comprises the use of any insulin receptor-activating compound, except insulin, for the treatment of a disease related to the use of an HIN protease inhibitor, such as insulin resistance, hyperglycemia, diabetes, ketoacidosis, lipodystrophy and hypertriglyceridemia. The present invention further comprises the use of any insulin receptor-activating compound, other than insulin, for the treatment of HIV protease inhibitor-induced insulin resistance, hyperglycemia, diabetes, ketoacidosis, lipodystrophy, or hypertriglyceridemia in humans. In particular, compounds of Formulas I- VII are herein disclosed as useful for the treatment of diseases related to the use of HIN protease inhibitors, and for the treatment of HIV protease inhibitor-induced insulin resistance, hyperglycemia, diabetes, ketoacidosis, lipodystrophy and hypertriglyceridemia in humans. The methods of the invention also include the co- administration of insulin in conjunction with the administration of receptor-activating compounds for the treatment of diseases related to the use of HIN protease inhibitors, and for the treatment of HIV protease inhibitor-induced insulin resistance, hyperglycemia, diabetes, ketoacidosis, lipodystrophy and hypertriglyceridemia in humans. Compounds of Formula I-IV are also disclosed as being useful in treating diabetes in co-pending applications US Serial Nos. 09/579,279, 60/208,591, and PCT/USOO/14644.

"Lower alkenyl" means any branched or unbranched unsaturated C2-C10 group having the number of carbon atoms specified, or up to 10 carbon atoms if no limitation on the number of carbon atoms is specified; and having 1 or more double bonds in the group. Lower alkenyl is exemplified by ethenyl, propenyl, butenyl, pentenyl, and hexenyl, in their various isomeric forms, where the unsaturated bond(s) can be located anywhere in the group. "Halo" means bromo, iodo, fluoro, or chloro. A "non-interfering substituent" means a substituent which, when present on a given compound, does not substantially decrease or otherwise inhibit a particular, desired bioactivity of the compound, such as the ability of the compound to reverse the glucose uptake inhibition caused by HIV protease-inhibitor drugs, to activate the insulin receptor, or to stimulate the uptake of glucose into cells. The presence of the non-interfering substituent should not detrimentally affect the bioactivity of the compound by more than about 30%. Preferably, the non-interfering substituent decreases the bioactivity of the compound by less than about 10%. Most preferably, the non-interfering substituent does not decrease the bioactivity of the compound to any detectable degree. However, the effect of the presence of the non-interfering substituent on the compound need not be neutral. For instance, the non-interfering substituent may optionally increase a particular bioactivity of the compound. Suitable non-interfering substituents include, but are not limited to, hydrogen, alkyl, substituted alkyl, cyano, halo, nitro, -SR, -OR, and -NRR', wherein R and R' are, independently, hydrogen, lower alkyl, or substituted lower alkyl. A "pharmaceutically acceptable salt" may be any salt derived from an inorganic or organic acid or an inorganic or organic base. The tenn "pharmaceutically acceptable anion" refers to the anion of such acid addition salts. The term "pharmaceutically acceptable cation" refers to a cation formed by addition of a base. The salt and/or the anion or cation are chosen not to be biologically or otherwise undesirable. "Stereoisomers" are compounds that have the same sequence of covalent bonds and differ in the relative disposition of their atoms in space. "Inner salts" or "Zwitterions" can be formed by transferring a proton from the carboxyl group onto the lone pair of electrons of the nitrogen atom in the amino group. "Therapeutically effective amount" means that amount which, when administered to an animal for treating a disease, is sufficient to effect such treatment for the disease. "Treating" or "treatment" of a disease in a mammal includes: (1) preventing the disease from occurring in a mammal which may be predisposed to the disease but does not yet experience or display symptoms of the disease, (2) inhibiting the disease, i.e., arresting or slowing its development, (3) relieving the disease, i.e., causing regression of the disease, or (4) relieving the symptoms of the disease, i.e., lessening the effects of the disease. "Disease" includes any unhealthy condition of a human, including, particularly, HIN protease inhibitor-induced insulin resistance, hyperglycemia, diabetes, ketoacidosis, lipodysfrophy, and hypertriglyceridemia.

The insulin receptor-activating compounds of the present invention have been found to stimulate autophosphorylation of the insulin receptor, hi addition, these compounds have been shown to enhance the fransport of glucose into cultured fibroblast cells after the cells treatment with a variety of HIV protease inhibitors. Although applicants do not wish to be bound by theory, it is believed that HlV-protease inhibitors reduce the association of glucose transporters with the cell membrane, and that the compounds of the invention are effective to enhance glucose fransport into HIN-protease inhibitor-affected cells by enhancing membrane-associative and other activity of glucose transporters. The ability of the compounds of this invention to stimulate the uptake of glucose into cells indicates their usefulness in the treatment and management of patients who have HW protease inhibitor-induced insulin resistance, hyperglycemia, diabetes, ketoacidosis, lipodystrophy, or hypertriglyceridemia. By virtue of the activities of the compounds of the invention, they may be used to stimulate the kinase activity of an insulin receptor, to enhance the activation of the insulin receptor by insulin, to enhance the stimulation by insulin of cellular glucose uptake, and to stimulate the uptake of glucose in subjects who have HIV protease therapy induced diabetes, ketoacidosis, insulin resistance, hyperglycemia, lipodysfrophy, or hypertriglyceridemia. Thus, insulin receptor-activating compounds, and, more specifically, the compounds of the invention, may be used in the preparation of medicaments for the treatment of any such disease induced by the use of an HIN protease inhibitor. The method may further comprise treating a patient who has complications due to HIN protease therapy with one or more additional forms of therapy for insulin resistance, hyperglycemia, diabetes, ketoacidosis, lipodystrophy, or hypertriglyceridemia, such as administering insulin to the patient. The insulin or other additional form of treatment may be delivered to the patient in an amount which is therapeutically effective when used in conjunction with a compound of the invention. This therapeutically effective amount of insulin or other additional form of treatment when used in combination with a compound of the invention may be less than the amount of insulin which would be therapeutically effective if delivered to the patient alone. It is understood that the insulin which is administered in any of the treatments of the present invention may either be isolated from a natural source or be recombinant insulin. In addition, an insulin analog may be substituted for insulin in any of the treatments of the present invention. Thus, a medicament prepared (for the treatment of any such disease induced by the use of an HIV protease inhibitor) utilizing an insulin receptor-activating compound, more specifically, a compound of the invention may further comprise an additional form of treatment, such as, for example, msulin or an insulin analog, of any such disease induced by the use of an HIV protease inhibitor. The methods of the invention for treating HIV protease induced diabetes, ketoacidosis, lipodysfrophy, hypertriglyceridemia, insulin resistance, or hyperglycemia by combination therapy may also comprise the administration of the compound of the invention to the patient in combination with a non-insulin, antidiabetic agent or other treatment for type II diabetes. For instance, the antidiabetic drug which is administered to the mammal in combination with a compound of the invention may optionally be a thiazolidinedione, such as troglitazone, or a sulphonylurea. The total amount of the combination of drugs (invention compound plus insulin, and/or other antidiabetic drug) administered to the mammal for the treatment of type II diabetes must be a therapeutically effective amount, although the amount of each of the individual drugs used in the combination therapy may be suboptimal for therapeutic purposes if that drug were to be delivered alone to the mammal with type II diabetes. Thus, a medicament prepared (for the treatment of any such disease induced by the use of an HIV protease inhibitor) utilizing an insulin receptor-activating compound, more specifically, a compound of the invention may further comprise an additional form of treatment, such as, for example, a non-insulin, antidiabetic agent, of any such disease induced by the use of an HIV protease inhibitor. The methods of the invention for treating HIV protease induced diabetes, ketoacidosis, lipodysfrophy, hypertriglyceridemia, insulin resistance, or hyperglycemia by combination therapy may also comprise the administration of a compound of the invention to the patient in combination with another compound of the invention. Thus, a medicament prepared (for the treatment of any such disease induced by the use of an HIV protease inhibitor) utilizing an insulin receptor-activating compound, more specifically, a compound of the invention may further comprise another compound of the invention. The compounds of this invention can be used in the preparation of a medicament for the treatment of a disease induced by the use of an HIV protease inhibitor. The compounds of this invention are thus used to enhance glucose uptake in patients on HIV protease therapy which require such treatment. The method of treatment comprises the administration of an effective quantity of the chosen compound of the invention, preferably dispersed in a pharmaceutical carrier. Preferred routes of administration are the parenteral and oral routes. The invention compounds may be administered by any route suitable to the subject being treated and the nature of the subject's disease. Routes of administration include, but are not limited to, administration by injection, including intravenous, infraperitoneal, intramuscular, and subcutaneous injection, by fransmucosal or transdermal delivery, through topical applications, nasal spray, suppository and the like or may be administered orally. Formulations may optionally be liposomal formulations, emulsions, formulations designed to administer the drug across mucosal membranes or transdermal fomiulations. Suitable formulations for each of these methods of administration may be found, for example, in Remington's Pharmaceutical Sciences, latest edition, Mack Publishing Company, Easton, PA. Dosage units of the active ingredient are generally selected from the range of 0.01 to 1000 mg/kg, preferably 0.01 to 100 mg/kg and more preferably 0.1 to 50 mg/kg, but will be readily determined by one skilled in the art depending upon the route of administration, age and disease of the patient. The compounds of the invention are most preferably administered in a dosage unit of 1 to 10 mg/kg. These dosage units may be administered one to ten times daily for acute or chronic disease. (d) Examples The Examples which follow serve to illustrate this invention, and are not intended to limit the scope of this invention, but are provided to show how to make and use the compounds of this invention. The compounds of this invention are prepared by conventional methods of organic chemistry, hi some cases, protective groups may be introduced and finally removed. Suitable protective groups for amino, hydroxy, carboxyl groups are described in Greene, et al., Protective Groups in Organic Synthesis, Second Edition, John Wiley and Sons, New York, 1991. Activation of carboxylic acids can be achieved by using a number of different reagents as described in Larock, Comprehensive Organic Transformations, VCH Publishers, New York, 1989. The compounds of Formula III are prepared by conventional methods of organic chemistry. Generally, a compound of the formula (A) wherein: R 1 and R 2 are, independently, hydrogen, lower alkyl, substituted lower alkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, heterocyclyl, substituted heterocyclyl, aryl(lower)alkyl, substituted aryl(lower)alkyl, heteroaryl(lower)alkyl, substituted heteroaryl(lower)alkyl, or lower alkenyl, or R 1 and R 2 together with the conjoining nitrogen are C3-C9 heteroaryl, or C3-C5 heterocyclyl, and Z is OH, CI, Br, F, OR 1 or NR R 2 wherein R 1 and R 2 are as defined above, or a pharmaceutically acceptable salt thereof, or a single stereoisomer or mixture of stereoisomers thereof; may be prepared by a process comprising: a) reaction of a 1,3,5-benzenetricarbonyl trihalide, wherein the halide is selected from the group consisting of CI, Br, and F, with at least 1 to at least 3 moles HNR^ 2 wherein R 1 and R 2 are as defined above; (b) reaction of an activated carboxy di-amide of the formula with a primary amine R 3 NH 2 or a secondary amine R 3 R NH, wherein M is any substituent that will allow reaction with said amine; for example, M can be halogen, formate, imidazole, or some other promoting or coupling reagent; or (c) acid esterification of a compound of the formula CONR 1 R 2 to form a compound of formula A; or 1 9 (d) chemical elaboration of one or more substituents of substituted R or R , wherein said substituent is convertible into another substituent; or 1 9 (e) conversion of a compound of Formula A with three NR R groups to a 1 9 compound of Formula I with one or two NR R groups, or (f) conversion of the compound of Formula A to a pharmaceutically acceptable salt; or (g) conversion of a salt of the compound of Formula A to a free compound; or (h) conversion of a salt of the compound of Formula A to a pharmaceutically acceptable salt; or (i) resolution of a racemic mixture of any proportions of the compound of Formula A to yield a stereoisomer thereof. Asymmetric compounds of Formula III can be prepared via the following reaction scheme: RιNH 2 A benzyl ester of the compound of the invention is hydrolyzed (under basic hydrolysis conditions or by catalytic hydrogenolysis) to yield a carboxyhc acid of the compound; this carboxyhc acid compound is subsequently converted into an acid cloride of the compound, which is reacted with an amine to yield an asymmetric form of the compound of the invention. As shown above, a differentially protected, mono-methyl, mono-benzyl esters of benzene tricarboxylic acid may be converted to the acid chloride using oxalyl chloride to give the corresponding mono-acylchloride. Reaction with an amine affords a mono- amido compound. Selective saponification of the methyl ester under basic conditions, followed by an acidic workup will give another carboxyhc acid which may be converted to the acid chloride using oxalyl chloride. Reaction with a second amine will now give an unsymmetrical compound. The final carboxyhc ester may be converted to the carboxyhc acid by more forcing saponification conditions, or by catalytic hydrogenolysis. After isolation of the carboxyhc acid, one can covert the carboxyhc acid into the acid chloride and then react with a third amine to give benzene compound with three differing amido substituents. It will be evident to a person of ordinary skill in the art that diamines may be used in place of monoamines in the above synthesis. In some cases, protective groups may be introduced and later removed. Suitable protective groups for amino, hydroxyl, carboxyl groups are described in Greene, et al., Protective Groups in Organic Synthesis, Second Edition, John Wiley and Sons, New York, 1991. Activation of carboxyhc acids can be achieved by using a number of different reagents as described in Larock, Comprehensive Organic Transformations, VCH Publishers, New York, 1989. The compounds of Formula IV are prepared by conventional methods of organic chemistry. Generally, the process for preparation comprises: (a) reaction of an iodo bis-amide compound of the formula wherein R ! -R 7 are as defined above, with a styrene or substituted styrene of the fomiula wherein R 8 -R 10 are as defined above; or (b) chemical elaboration of one or more substituents R -R 10 wherein said substituent is convertible into another substituent R^R 10 ; or (c) introduction of a substituent R^R 10 into one, two or all three of the phenyl rings; or (d) deprotection of a protected group; or (e) salt formation or interconversion; or (f) ester hydrolysis; or (g) liberation of a free acid or base of a compound of Formula TV, wherein R 1 - R 12 are as defined above; or (h) stereoisomer separation or synthesis. The reaction of the iodo bis-amide compound with the styrene or substituted styrene shown in (a), above, can be carried out between 40 C and 120 C in the presence of such solvents as DMF, toluene, methylene chloride, or the like. Chemical elaboration of one or more substituents R^R 10 via the conversion of one such substituent into another substituent may be accomplished via hydrolysis, salt formation, acidification, alkylation, esterification, oxidation, or reduction. In hydrolysis, an ester or amide compound is dissociated by reaction with water. Hydrolysis is catalyzed by acid or base, and hydrolysis of an amide generally requires more vigorous conditions (for example, a higher concentration of sulfuric acid at 1 to 100 C for 1 to 5 hours) than those required for the hydrolysis of esters. Hydrolysis reactions can also be carried out with aqueous hydrochloric acid at 100 to 150 C and may require as long as 18 hours. hi salt formation, a free acid is converted into a salt via addition of a basic reagent, such as aqueous sodium hydroxide or triethanolamine, that replaces all or part of the hydrogen ions of the acid with one or more cations of a base. The conversion of a compound into its corresponding acid addition salt is accomplished via treatment with a stoichiometric amount of an appropriate acid, such as hydrochloric acid. Typically, the free base is dissolved in a polar organic solvent, such as methanol or ethanol, and the acid is added in methanol or ethanol. The temperature is maintained at 0 to 50 C. The corresponding salt precipitates spontaneously or can be brought out of solution with a less polar solvent. In acidification, a chemical compound is converted into an acid. In alkylation, an alkyl group is added to or substituted in a compound. Alkylation is carried out in a suitable solvent, such as acetonitrile, DMF, or THF, at 0 ot 160 C, typically at approximately 25 C to reflux, and requires some 1 to 18 hours. An esterification reaction results in the formation of at least one ester product. In brief, the compound is reacted with from 1.0 to 5.0, preferable 2.0, molar equivalents of an alkanol, a thiol or ammonia, a monoalkyl, or dialkylamine, or a heterocyclic aminoalkanol, optionally in the presence of from 1.0 to 1.5, preferably 1.25, molar equivalents of a tertiary organic base such as 4-dimethylaminopyridine or, preferably, triethylamine, in an organic solvent such as dioxane, tefrahydrofuran, or, preferably, dichloromethane. The reaction takes place at -10 to 50 C, preferably at ambient temperature, for 1 to 24 hours, preferably 4 hours. Examples of syntheses of specific compounds usable in the invention follow. Example 1 Compound 1 Preparation of Compound 1 4-hydroxy- 7 -{[(5 -hydroxy- 7-sulfo(2- naphthyl)) amino] carbonylamino}naphthalene-2-sulfonic acid disodium salt. To 10.77 g (0.045 moles) of 7-amino-4-hydroxynaphthalene-2-sulfonic acid dissolved in 45 mL of 1 N aqueous NaOH and 50 mL of water was added 3.70 g (0.045 moles) of sodium acetate. The pH of the solution was above 9. The reaction was cooled to under 5°C in an ice- water bath. Then, 2.23 g (0.045 mole) of triphosgene dissolved in 15 mL of THF was added in three portions. The pH of the reaction fell to 4-5 and was readjusted to 7-8 by the dropwise addition of IN aqueous NaOH. TLC (6:2:1 ethyl acetate:isopropanol:water) indicated the reaction was incomplete. Another 2.20 grams (0.045 moles) of triphosgene in 10 mL of THF was added portionwise with the pH kept above 7 by the addition of IN aqueous NaOH. When the reaction was judged complete by TLC, the pH was lowered to 1 with aqueous HC1 and the volatiles were removed by rotary evaporation. The solid product was collected by vacuum filtration. This resulted in the recovery of 10.85 g of the desired compound. 7-{[(7-(chlorosulfonyl)-5-hydroxy(2-naphthyl))amino]carbonylamino}-4- hydroxynaphthalene-2-sulfonyl chloride. To 500 mg (0.912 mmol) of 4-hydroxy-7-{[(5- hydroxy-7-sulfo(2-naphthyl))amino]carbonylamino}naphthalene-2-sulfonic acid disodium salt, suspended in 8 mL of phosphorous oxychloride was added 25 mL of 1:1 (v:v) sulfolane:acetonitrile and 0.5 mL of dimethylacetamide. The reaction mixture was allowed to stir at ambient temperature for 16 hours. The reaction became a clear solution which was poured onto 500 mL of ice. The ice mixture was placed in an ice bath and allowed to warm to room temperature. The resulting solid was collected by vacuum filtration and was washed with water. The solid was dried under high vacuum for 24 hours. This provided 412 mg of desired compound. 5-{[(7-{[N-(7-{[(4-chloro-3-benzenesulfonic acid)amino] sulfonyl}- 5-hydroxy(2- naphthyl)carbamoyl]amino}-4-hydroxy(2-naphthyl))sulfonyl]amino}-2- chlorobenzensulfonic acid. To 0.15 g (0.277 mmol) of 7-{[(7-(chlorosulfonyl)-5- hydroxy(2-naphthyl)) amino]carbonylamino}-4-hydroxynaphthalene-2-sulfonyl chloride was added 1.5 mL of freshly distilled THF followed by 0.105 g (0.610 mmol) of 5- amino-2-chlorobenzensulfonic acid. To this solution was added 67 uL (0.831 mmol) of pyridine. The reaction was allowed to stir at ambient temperature for 16 hours. Then, the reaction was partitioned between IN HC1 (aqueous) and ethyl acetate. The aqueous layer was extracted a second time with ethyl acetate and the combined organic layers were dried (MgSO4), filtered and volatiles removed by rotary evaporation. This provided 0.14 g of the desired compound. Compound 2 Example 2 Reversal of HIN protease inhibitor block of glucose transport in cells. Stimulation of the insulin receptor leads to the transport of glucose from the blood into cells, thus modulating blood glucose levels. 3T3 Ll fibroblasts (ATCC) were grown in Dulbecco's modified Eagle's medium (DMEM) with 10% fetal bovine serum (FBS). The cells were plated at a density of 3x10 4 cells/ml in 96 well plates (0.1 ml/well). Two days after confluence was reached, the cells were freated for 3 days with 0.5 mM isobutylmethylxanthine (IBMX), 1 μM dexamethasone, and 1.7 μM insulin. The cells were then transferred to DMEM with 10% FBS and supplemented with 1.7 μM insulin for 2 more days. The cells were maintained in DMEM with 10% FBS for an additional 4 days. Finally, the cells were serum starved overnight in 0.1% bovine serum albumin (BS A) in DMEM. The following day, the cells were preheated with fridinavir, Ritonavir, or Amprenavir (at the concentrations indicated in the Tables below) in a buffer containing 150 mM ΝaCl, 1.7 mM KC1, 0.9 mM CaCl 2 1.47 mM K 2 HPO 4 (pH 7.4) and 0.01% BSA for 6 minutes followed by treatment with a compound described in this patent (56 μM compound 1; 20 μM compound 2) with or without 100 nM insulin for 30 minutes. Following incubation, the cells were labeled with 14 C-labeled 2-deoxy-D-glucose (0.5 μCi/ml) and incubation was continued for additional 30 minutes at 37°C. The cells were then washed 3 times with ice-cold PBS/20 mM glucose and lysed in 100 μl of lysis buffer (50 mM Hepes pH 7.6, 1% Triton X-100) for 30 minutes at room temperature. Radioactivity in the lysate was quantified by scintillation counting. Once 14 C-2-deoxy-D-glucose is transported into the cells, it is not released. Glucose transport is, therefore, proportional to the amount of radioactivity in the lysate. Results: Compounds 1 and 2 were demonstrated to increase the glucose transport activity in 3T3 Ll adipocytes which was otherwise inhibited by presence of commercial HIV protease inhibitor drugs, Ritonavir, Indinavir, or Amprenavir. Each of these drugs is lαiown to induce insulin-resistance and other related disturbances in metabolism, such as lipodysfrophy and hypertriglyceridemia, in patients treated with these HIN protease inhibitors. The results are summarized below: Indinavir Ritonavir Example 3 Compound 3 Preparation of Compound 3 Compound 3 was synthesized by a method similar to the method disclosed in Example 1, except that the final steps following synthesis of 7-{[(7-(chlorosulfonyl)-5- hydroxy(2-naphthyl))amino]carbonylamino} -4-hydroxynaphthalene-2-sulfonyl chloride were as described below: 5-{[(7-{[N-(7-{[(3-carboxy-4-chlorophenyl)amino]sulfonyl}-5-hydroxy(2- naphthyl))carbamoyl]amino}-4-hydroxy(2-naphthyl))sulfonyl]amino}-2-chlorobenzoic acid. To 0.15 g (0.277 mmol) of 7-{[(7-(chlorosulfonyl)-5-hydroxy(2- naphthyl))amino]carbonylamino}-4-hydroxynaphthalene-2-sulfonyl chloride was added 1.5 mL of freshly distilled THF followed by 0.105 g (0.610 mmol) of 5-amino-2- chlorobenzoic acid. To this solution was added 67 uL (0.831 mmol) of pyridine. The reaction was allowed to stir at ambient temperature for 16 hours. Then, the reaction was partitioned between IN HC1 (aqueous) and ethyl acetate. The aqueous layer was extracted a second time with ethyl acetate and the combined organic layers were dried (MgSO4), filtered and volatiles removed by rotary evaporation. This provided 0.14 g of the desired compound. Example 4 Reversal of protease inhibitor-mediated insulin resistance in normal rats by compound 1 Seven to nine week-old male CD rats (Charles River Laboratories, Hollister, CA) were used to study the effects of protease inhibitor and compound 1. Animals were kept in a l2 h/12 h light/dark cycle and were fasted overnight. Indinavir sulfate was prepared in water, and compound 1 was prepared in PBS. Seven animals (average weight 300 grams) were used in each treatment condition. The animals were freated with vehicle or indinavir sulfate or indinavir sulfate plus compound 1 by oral administration. After 30 min, the animals were challenged with oral glucose load (2 g/kg), and blood glucose measurements were taken at 0 min, 10 min, 20 min, 30 min, 60 min, 90 min and 120 min by tail bleeding. Glucose measurements were made with a Glucometer and Glucose strips (Bayer). The resulting data are shown in Figures 1 and 2. Fig 1 shows the effect of indinavir on blood glucose levels following oral glucose challenge. The blood glucose levels are reported as the percentage of the "0-time" values. Fig 2 shows the effect of indinavir and indinavir plus compound on plasma insulin levels. Blood samples obtained from 0 min and 30 min time points were analysed for plasma insulin levels by ELIS A (ALPCO Diagnostics, Windham, NH)
