Abstract: A method is disclosed for the treatment of of the symptoms associated with renal dysfunction by administering to an animal in need thereof a therapeutically effective amount of a sPLA2 inhibitor, such as a 1H-indole-3-glyoxylamide.

Description: METHOD FOR THE TREATMENT OF RENAL DYSFUNCTION WITH SPLA 2 INHIBITORS FIELD OF THE INVENTION The present invention is directed to a method for treating renal dysfunction. More specifically, the present invention is directed to- a method for treating the symptoms of renal dysfunction by administering a therapeutically effective amount of a SPLA2 inhibitor. BACKGROUND OF THE INVENTION Renal failure can be either acute or chronic. Acute renal failure (ARF) is a very common renal disease affecting about 5% of all hospitalized patients. ARF carries a high mortality of more than 50% and there has been no significant change in the mortality rate over the past four decades. The effects of acute renal failure may be reversible with prompt and proper intervention and treatment . Chronic renal failure on the other hand is often not reversible. Common initiating causes of chronic renal failure (CRF) include glomerulonephritis, diabetes mellitus, and hypertension. CRF is characterized by progressive reduction in nephron mass, which eventually impacts the operation of virtually every major organ in the body. The clinical syndrome that results from profound loss of renal function is called uremia. The term encompasses more than just a presumed retention of urea and other toxins but includes the impairment of a host of metabolic and endocrine functions normally subserved by the kidney. Symptoms of uremia include for example, hypothermia- caused possibly by retention of urea and other toxins, impaired glucose metabolism, uremic toxicity caused by an inability to eliminate end products of protein metabolism, fluid and electrolyte imbalance, gastrointestinal disturbances e.g. nausea, anorexia, uremic factors, and peptic ulcer. Other symptoms of CRF include arterial hypertension, congestive heart failure, dermatological disturbances, e.g. itching, neurologic disturbances e.g. impaired mentation, headache, seizures, and immunological disturbances such as for example, leukopenia, lymphocytopenia, bleeding diathesis. (See generally, Harrisson's Principles of Internal Medicine, Isselbacher, K. J. et . al . , editors, pages 1259-1284, 13th edition, 1994, McGraw-Hill Publishers, NY, New York.) Because there is neither clear understanding of the cause nor the mechanism of action of ARF, CRF or any of the related renal dysfunctional problems, numerous scientific publications have posited theories . One theory examines the controversial involvement of sPLA2~induced cell membrane damage (Edelstein, C.L.; Ling, H. ; Schrier, R.W. ; International Society of Nephrology, 51, 1997, 1341-1351). Edelstein et al . propose a dual mode of action for SPLA2 and SPL 2 inhibitors because both cell death and cellular protection are seemingly involved. U.S. Pat. No. 5,654,326 which is incorporated herein by reference, describes lH-indole-3-glyoxylamide SP A2 inhibitors for use in inhibiting SP A2 mediated release of fatty acids in conditions such as septic shock. Major therapies for renal dysfunction include the following: 1. Dialysis treatment to remove harmful toxins 2. Drugs to restore salt and water balance, e.g., ' diuretics 3. Antibiotics 4. Inhaled beta-adrenergic agonists However, previous treatment attempts have focused on pharmaceutical agents that treated the cause of the renal dysfunction. For example, previous methods treated the problem causing renal dysfunction and not, for example, the build up of fluids or cell membrane damage. Also of importance are the problems relative to renal organ transplant . Transplantation of kidneys and associated tissues creates additional sepsis and tissue rejection concerns. M. Baur et al . have reported increased PLA levels in patients undergoing major surgery (Baur, M. ; Schmid, T. O . ; Landauer, B.; Klin . Wochenschr. , Vol. 67(3), 1989. Baur et al . further observed that serum PLA levels decrease spontaneously in recovering postsurgical patients. Accordingly, there i-s a substantial need for an effective treatment for the many symptoms secondary to renal dysfunction including sepsis, inflammation, cell membrane damage, secondary to organ failure and tissue rejection following kidney transplant. SUMMARY OF THE INVENTION The present invention is directed to a method of alleviating the symptoms of an animal afflicted with renal dysfunction e.g., acute or chronic renal failure, by administering a therapeutically effective amount of a SP A2 inhibitor compound. The present invention also relates to the use of a SPLA2 inhibitor in combination with a therapeutically effective agent and or medical procedure selected from the group consisting of, dialysis treatment to remove harmful toxins; drugs to restore salt and water balance; and/or other treatment of acute and chronic renal failure. The invention also relates to the combination of a SPLA2 inhibitor with ANF atrial naturetic factor for the delay or prevention of acute renal failure in a mammal . This invention also relates to the use of a SP A2 inhibitor in combination with erythropoetin to stimulate red cell production in a mammal. The present invention is also the use of a SPLA2 inhibitor in combination with 0KT3™ (a monoclonal antibody used to prevent graft rejection by T3 antigens produced by human T cells) , to reduce the symptoms associated with administration of 0KT3. DETAILED DESCRIPTION OF THE INVENTION Definitions; General Definitions: As used herein "Renal dysfunction" means a disease state or condition wherein the renal tissues fail to perform their normal functions according to competent medical authority. Renal dysfunction shall also include long term or chronic renal dysfunction also known as renal failure. Renal dysfunction also includes acute renal failure and disease states that lead to renal failure. Examples of disease states leading to renal failure include for example, acute nephritis, nephrotic syndrome, pyuria, auria, oliguria, uremia, bilateral arterial occlusion, acute tubular necrosis, acute uric acid nephropathy, hypovolemia, acute bilateral upper tract obstruction, hypocalcemic nephropathy, hemolytic uremic syndrome, acute urinary retention, scleroderma, hypersensitivity nephropathy, malignant nephrosclerosis, essential and mixed cryoimmunoglobulinemia, and azotemia. The term "uremia" means the clinical syndrome of nausea, itching, weight loss, sleep disturbances, altered mentation, and memory loss associated with renal dysfunction . The terms "SP A2 inhibitor" and "SPLA2 inhibitor compound" as used herein are synonymous. The term "therapeutically effective amount" is a quantity of SP A2 inhibitor sufficient to ameliorate the symptoms secondary to renal dysfunction in an animal. The term "therapeutically effective interval" is a period of time beginning when one of either the SPLA2 inhibitor or the co-agent is administered or practiced on the patient in need thereof, and ending at the limit of the therapeutic effectiveness of either or both. The terms "parenteral" or "parenteral administration" mean administration by a route such as subcutaneous, intramuscular, intraorbital, intracapsular, intraspinal, intrasternal, transdermal, transmucosal, transbuccal, transrectal, transvaginal , transnasal or intravenous . The term "animal" means any member of the animal kingdom including mammals, reptiles, fishes and fowls. The term "active compound" means one or more SPLA2 inhibitors used in the method of the invention. The term "in combination with" denotes the co- administration of a SPLA2 inhibitor and a co-agent therapy or procdeure. The term further means simultaneous co-administration either as a single formulation or as separate formulations or sequential administration of a SPLA2 inhibitor and co-agent or other therapeutically effective procedure. The term "co-agent" is a theraputically effective medication or procedure administered in combination with a SPLA2 inhibitor either as a single dose unit or as separate dose units simultaneously or sequentially within a therapeutic interval . PREFERRED ASPECTS OF THE INVENTION A preferred aspect of the invention is the use of a SP A2 inhibitor compound of the invention for the prevention or treatment of uremia. Preclinical studies showed that monkeys and rabbits in renal failure did not develop signs of uremia i.e., the kidneys were failing but the animals were not as clinicallly ill as they should have been. Another preferred aspect of the present invention is the use of a SPL 2 inhibitor in combination with an anti- rejection drug, e.g., OKT3™ for the treatment of chronic or acute inflammation associated with kidney transplant therapy . Also preferred is the use of SPLA2 inhibitor in combination with erythropoietin to stimulate the production of red cells in renal failure patients. I.

The ortho-nitrotoluene, 1, is readily reduced to the 2-methylaniline, 2, using Pd/C as catalyst. The reduction can be carried out in ethanol or tetrahydrofuran (THF) or a combination of both, using a low pressure of hydrogen. The aniline, 2, on heating with di-tert-butyl dicarbonate in THF at reflux temperature is converted to the N-tert-butylcarbonyl derivative, 3, in good yield. The dilithium salt of the dianion of 3 is generated at -40 to -20 °C in THF using sec-butyl lithium and reacted with the appropriately substituted N-methoxy-N-methylalkanamide . This product, 4, may be purified by crystallization from hexane, or reacted directly with trifluoroacetic acid in methylene chloride to give the ' 1, 3-unsubstituted indole 5. The 1, 3-unsubstituted indole 5 is reacted with sodium hydride in dimethylformamide at room temperature (20-25 °C) for 0.5-1.0 hour. The resulting sodium salt of 5 is treated with an equivalent of arylmethyl halide and the mixture stirred at a temperature range of 0-100 °C, usually at ambient room temperature, for a period of 4 to 36 hours to give the 1-arylmethylindole, 6.

An appropriately substituted nitrobenzene (1) can be reduced to the aniline (2) by treatment with a reducing agent, such as hydrogen in the presence of Pd/C, preferably at room temperature. Compound (2) is N-alkylated at temperatures of from about 0 to 20 °C using an alkylating agent such as an appropriately substituted aldehyde and sodium cyanoborohydride to form (3). Alternately, an appropriately substituted benzyl halide may be used for the first alkylation step. The resulting intermediate is further N-alkylated by treatment with 2-carbethoxy- 6-bromocyclohexanone, preferably at temperatures of about 80 °C to yield (4) or by treatment with potassium hexamethyldisilazide and the bromoketoester . The product (4) is cyclized to the tetrahydrocarbazole (5) by refluxing with zncl2 in benzene for from about 1 to 2 days, preferably at 80 C (see Julia, M. ; Lenzi, J. Preparation d'acides tetrahydro-1, 2, 3 , 4-carbazole-l ou -4. Bull . Soc . Chim. France, 1962, 2262-2263). Compound (5) is converted to the hydrazide (6) by treatment with hydrazine at temperatures of about 100 °C, or to the amide (7) by reacting with methylchloroaluminum amide in benzene (see Levin, J.I.; Turos, E.; Weinreb, S.M. An alternative procedure for the aluminum-mediated conversion of esters to amides. Syn . Comm. , 1982, 12, 989-993) . Alternatively, (7) may be produced by treatment of (6) with Raney nickel active catalyst. It will be readily appreciated that when R 3 ( a ) χ S: 0 -(CH 2 )nCO (C-^^ alkyl), Conversion to the amide will also be achieved in this procedure. Compounds (6) and (7) may be dealkylated, preferably at 0 °C to room temperature, with a dealkylating agent, such as boron tribromide or sodium thioethoxide, to give compound (7) where R2 ( a ) χ s _OH, which may then be further converted to compound (9) , by realkylating with a base, such as sodium hydride, and an alkylating agent, such as Br(CH2)m r ^' where R^ is the carboxylate or phosphonic diester or nitrile as defined above. Conversion of R^ to the carboxylic acid may be accomplished by treatment with an aqueous base. When R2 is nitrile, conversion to the tetrazole may be achieved by reacting with tri-butyl tin azide or conversion to the carboxamide may be achieved by reacting with basic hydrogen peroxide. When R^ is the phosphonic diester, conversion to the acid may be achieved by reacting with a dealkylating agent such as trimethylsilyl bromide. The monoester may be accomplished by reacting the diester with an aqueous base. When R2 and R 3 are both methoxy, selective demethylation can be achieved by treating with sodium ethanethiolate in dimethylformamide at 100 °C. An alternative synthesis of intermediate (5) is shown in Scheme 1(b), as follows. Scheme Ig(b) (2; (4') where PG is a protecting group; R a is as defined in Scheme 1, above, The aniline (2) is N-alkylated with 2-carbethoxy-6- bromoeyelohexanone in dimethyl formamide in the presence of sodium bicarbonate for 8-24 hours at 50 °C. Preferred protecting, groups include methyl, carbonate, and silyl groups, such as t-butyldimethylsilyl . The reaction product (4') is cyclized to (5') using the zncl2 in benzene conditions described in Scheme 1(a), above. N- alkylation of (5') to yield (5) is accomplished by treatment with sodium hydride and the appropriate alkyl halide in dimethylformamide at room temperature for 4-8 hours . Scheme iig R3 ( a ) χ s as defined in Scheme Ig. As discussed in Scheme I above, carbazole (5) is hydrolyzed to the carboxylic acid (10) by treatment with an aqueous base, preferably at room temperature to about 100 °C . The intermediate is then converted to an acid chloride utilizing, for example, oxalyl chloride and dimethylformamide, and then further reacted with a lithium salt of (S) or (R) -4-alkyl-2-oxazolidine at a temperature of about -75 °C, to give (11a) and (lib), which are separable by chromatography. The diastereomers are converted to the corresponding enantiomeric benzyl esters (12) by brief treatment at temperatures of about 0°C to room temperature with lithium benzyl oxide (see Evans, D.A. ; Ennis, M.D.; Mathre, D.J. Asymmetric alkylation reactions of chiral imide enolates. A practical approach to the enantioselective synthesis of alpha- substituted carboxylic acid derivatives J. Am. Chem. Soc . , 1982, 104, 1737-1738) . The esters (12) are then converted to (7) preferably by treatment with methylchloroalummum amide (Ref 2, above) or, alternately, by hydrogenation using, for example, hydrogen and palladium on carbon, as described above, to make the acid and then reacting with an acyl azide, such as diphenylphosphoryl azide followed by treatment with ammonia. Using the procedure described above in Scheme I, compound (9a) or (9b) may be accomplished. Compounds of formula Ie where Z is phenyl can be prepared as follows in Schemes III (a) -(f), below.

Alternately, treatment of (13) with DDQ in an appropriate solvent such as dioxane yields carbozole (14) . Depending on the substituent pattern oxidation as described above may result in de-alkylation of the nitrogen. For example when R 3 is substituted at the 8- position with methyl, oxidation results in dealkylation of the nitrogen which may be realkylated by treatment with sodium hydride and the appropriate alkyl halide as described in Scheme 1(a) above to prepare the deired product (14) .

FORMULATIONS SUITABLE FOR USE IN THE METHOD OF THE INVENTION The SPLA2 inhibitors used in the method of the invention may be administered to treat renal dysfunction by any means that produces contact of the active agent with the agent's site of action in the animal body. They can be administered by any conventional means available for use in conjunction with pharmaceuticals, either as individual therapeutic agents or in a combination of therapeutic agents . The SPLA2 inhibitors can be administered alone, but are generally administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice. Suitable formulations are those comprising a therapeutically effective amount of SPLA2 inhibitor together with a pharmaceutically acceptable diluent or carrier, the composition being adapted for the particular route of administration chosen. By "pharmaceutically acceptable" it is meant the carrier, diluent or excipient must be compatible with the SPLA2 inhibitor ("active compound" ) in the formulation and not deleterious to the subject being treated. For the pharmaceutical formulations any suitable carrier known in the art can be used. In such a formulation, the carrier may be a solid, liquid, or mixture of a solid and a liquid. A solid carrier can be one or more substances which may also act as flavoring agents, lubricants, solubilisers, suspending agents, binders, tablet disintegrating agents and encapsulating material . Tablets for oral administration may contain suitable excipients such as calcium carbonate, sodium carbonate, lactose, calcium phosphate, together with disintegrating agents, such as maize, starch, or alginic acid, and/or binding agents, for example, gelatin or acacia, and lubricating agents such as magnesium stearate, stearic acid, or talc. , In tablets the SPLA2 inhibitor is mixed with a carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired. The powders and tablets preferably contain from about 0.01 to about 99 weight percent of the SPLA2 inhibitor. Sterile liquid form formulations include suspensions, emulsions, syrups and elixirs. The active compound can be dissolved or suspended in a pharmaceutically acceptable carrier, such as sterile water, saline, dextrose solution, sterile organic solvent or a mixture of both. The active compound can be administered orally in solid dosage forms, such as capsules, tablets, and powders, or in liquid dosage forms, such as elixirs, syrups, and suspensions. It can also be administered parenterally, in sterile liquid dosage forms. It can also be administered by inhalation in the form of a nasal spray or lung inhaler. It can also be administered topically as an ointment, cream, gel, paste, lotion, solution, spray, aerosol, liposome, or patch. Dosage forms used to administer the active compound usually contain suitable carriers, diluents, preservatives, or other excipients, as described in Remington's Pharmaceutical Sciences, Merck Publishing Company, a standard reference text in the field. Gelatin capsules may be prepared containing the active compound and powdered carriers, such as lactose, sucrose, mannitol, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets and powders . Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract. Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance . For parenteral solutions, water, a suitable oil, saline, aqueous dextrose (glucose) , and related sugar solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral administration contain the active compound, suitable stabilizing agents, and if necessary, buffer substances. Anti-oxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid either alone or combined are suitable stabilizing agents. Also used are citric acid and its salts and sodium EDTA.

PROPORTION AND WEIGHT OF ACTIVE COMPOUNDS USED IN THE METHOD OF THE INVENTION The lH-indole-3-glyoxylamide compound may be used at a concentration of 0.1 to 99.9 weight percent of the formulation. Preferably the pharmaceutical formulation is in unit dosage form. The unit dosage form can be a capsule or tablet itself, or the appropriate number of any of these. The quantity of active compound in a unit dose of composition may be varied or adjusted from about 0.1 to about 1000 milligrams or more according to the particular treatment involved. Compositions (dosage forms) suitable for internal administration contain from about 1 milligram to about 500 milligrams of active compound per unit. In these pharmaceutical compositions the active compound will ordinarily be present in an amount of about 0.5-95% by weight based on the total weight of the composition. Examples of useful pharmaceutical compositions and their proportions of ingredients are illustrated as follows: Capsules: Capsules may be prepared by filling standard two-piece hard gelatin capsules each with 50 mg of powdered active compound, 175 mg of lactose, 24 mg of talc, and 6 mg of magnesium stearate. Soft Gelatin Capsules: A mixture of active compound in soybean oil is prepared and injected by means of a positive displacement pump into gelatin to form soft gelatin capsules containing 50 mg of the active compound. The capsules are washed in petroleum ether and dried. Tablets: Tablets may be prepared by conventional procedures so that the dosage unit is 50 mg of active compound, 6 mg of magnesium stearate, 70 mg of microcrystallme cellulose, 11 mg of cornstarch, and 225 mg of lactose. Appropriate coatings may be applied to increase palatability or delay absorption. Suspensions: An aqueous suspension is prepared for oral administration so that each 5 ml contain 25 mg of finely divided active compound, 200 mg of sodium carboxymethyl cellulose, 5 mg of sodium benzoate, 1.0 g of sorbitol solution, U.S. P., and 0.025 mg of vanillin. Injectables: A parenteral composition suitable for administration by injection is prepared by stirring 1.5% by weight of active compound in 10% by volume propylene glycol and water. The solution is sterilized by commonly used techniques. Nasal Spray: An aqueous solution is prepared such that each 1 ml contains 10 mg of active compound, 1.8 mg methylparaben, 0.2 mg propylparaben and 10 mg methylcellulose. The solution is dispensed into 1 ml vials . The active compound may be used at a concentration of 0.01 to 99.9 weight percent of the formulation. Aerosol formulations are capable of dispersing into particle sizes of from about 0.5 to about 10 microns and have sufficient SPLA2 inhibitor to achieve concentrations of the inhibitor on the airway surfaces of from about 10 "10 to 10 "2 moles per liter. THE PRACTICE OF THE METHOD OF THE INVENTION The use of SPLA2 inhibitors in the method of the invention prevents progressive deterioration by inhibiting or reducing the degree of renal dysfunction that may be a primary pathologic process in renal dysfunction. The method of the invention is preferably used early in the symptomatic-life of the patient afflicted with renal dysfunction. The method of the invention can be practiced using pharmaceutical formulations containing SPLA2 inhibitors (preferably, SPLA2 inhibitors identified as preferred herein) or formulations containing such ΞPLA2 inhibitors as taught in the preceding section. Although it is believed that the underlying causes of renal dysfunction will not be prevented by the method of this invention, the symptoms will be reduced in severity or extent by administration of SPL 2 inhibitors (and their formulations) . The dosage administered will vary depending upon known factors such as the pharmacodynamic characteristics of the particular agent, and its mode and route of administration; age, health, and weight of the recipient; ' nature and extent of symptoms, kind of concurrent treatment, frequency of treatment, and the effect desired. Usually a daily dosage of active compound can be about 0.1 to 200 milligrams per kilogram of body weight. Ordinarily 0.5 to 50, and preferably 1 to 25 milligrams per kilogram per day given in divided doses 1 to 6 times a day or in sustained release form is effective to obtain desired results. In general, the SPLA2 inhibitor will be administered to an animal so that a therapeutically effective amount is received. A therapeutically effective amount may conventionally be determined for an individual patient by administering the active compound in increasing doses and observing the effect on the patient, for example, improvement in exercise, increased appetite, or a reduction in other symptoms associated with renal dysfunction. Generally, the compound must be administered in a manner and a dose to achieve in the animal a blood level concentration of SPLA2 inhibitor of from 10 to 3000 nanograms/ml , and preferably a concentration of 100 to 800 nanograms/ml . The treatment regimen may stretch over many days to months or to years. Oral dosing is preferred for patient convenience and tolerance. With oral dosing, one to four oral doses per day, each from about 0.01 to 25 mg/kg of body weight with preferred doses being from about 0.1 mg/kg to about 2 mg/kg. Parenteral administration (particularly, intravenous administration) is often preferred in instances where rapid alleviation of patient distress is required. With parenteral administration doses of 0.01 to 100 mg/kg/day administered continuously or intermittently throughout the day may be used. For parenteral administration, the compound may be administered in a physiologic saline vehicle (e.g., 0.9% normal saline, 0.45% normal saline, etc.) a dextrose vehicle (e.g., 5% dextrose in water), or a combination of saline and dextrose vehicle (0.9% normal saline in 5% dextrose) . Inhalation therapy also may be useful either alone or as an adjunct to other routes of administration. With inhalation therapy, doses necessary to produce a decrease in the clinical symptoms of renal dysfunction are readily determined and used. TESTING METHODS FOR RENAL DYSFUNCTION The diagnostic criteria for renal dysfunction are those found in standard medical references (e.g., Harrison's Principles of Internal Medicine, thirteenth ed., 1994, by McGraw-Hill, Inc., ISBN 0-07-032370-4) . These criteria, or criteria designated by competent medical opinion may be used to determine when to begin using the method of the invention, the frequency and degree of treatment, and the time for cessation of treatment . For example, the renal dysfunction patient having renal disease may be evaluated with any conventional measure of renal capacity. The renal dysfunction patient having gastrointestinal disease may be evaluated by conventional criteria for adequate nutrition. The underlying renal dysfunction event may be evaluated and treated according to current standards of good medical practice, where the standard treatment is supplemented with the administration of a compound according to this invention. Results of a To Evaluate the Effects of Compound 374388 in Fischer 344 Rats with Surgically Induced Chronic Renal Failure Study R09199 374388 is an oralsPLA2 inhibitor compound of the present invention. The purpose of this study was to evaluate the effect of 374388 in a model of chronic renal failure in male Fisher 344 (F344) rats, when administered daily by gavage. Doses of 0, 3 or 30 mg/kg were administered for approximately 2 months (dosing begun approximately 60 days after the nephrectomy performed at Lilly Research Laboratories) . Alterations in live phase, and morphologic and clinical pathology parameters were compared to findings in age-matched control, sham- nephrectomized control, and vehicle-control nephrectomized rats. No compound-related alterations suggestive of toxicity occurred. Chronic renal failure was successfully induced in nephrectomized rats. The only remarkable difference in mortality among the nephrectomized groups was an increased number of rats in the 30mg/kg group that died during the pretreatment phase . The high pretreatment mortality in this group was likely due to the increased area of renal infarction seen in most rats in the 30- mg/kg group at necropsy, resulting in a more rapid onset of renal failure. Due to the mortality in this group, data from this group were not analyzed statistically. Body weight and body weight gains were improved in uremic rats given 3 mg/kg 374388 compared to nephrectomized controls. Near the end of the treatment phase (Day 112), mean body weight for rats given 3 mg/kg was significantly increased relative to the nephrectomized control value and was within approximately 5% of the control group mean, as compared to 19% for nephrectomized control rats. Although not statistically analyzed, body weight change data for rats given 30 mg/kg followed the same general trend as that seen in the 3-mg/kg group. Alterations in clinical and morphologic pathology parameters in nephrectomized rats were attributed to the model (chronic renal failure-uremia) . Alterations in these parameters, in general, were less pronounced in nephrectomized rats given 374388, suggesting that this compound may ameliorate the effects of uremia. On Day 117, nephrectomized rats given 3mg/kg had minimal increases in cholesterol, total protein, and total carbon dioxide and slight to moderate decreases in BUN, CREAT and IP compared to nephrectomized controls. Nephrectomized control rats surviving to study termination had more severe nephropathy, and a higher incidence of secondary parathyroid hyperplasia, fibrous osteodystrophy and periarteritis nodusus, compared to nephrectomized rats given 3 mg/kg. In conclusion, this, study demonstrated a reliable model of chronic renal failure in the rat. Data from this preliminary study suggest that daily doses of 3 mg/kg of 374388 ameliorated the effects of uremia in rats with surgically induced chronic renal failure. Therefore, 374388 and other members of the class of compounds of formula I may be potential therapeutic agents for the treatment of chronic renal failure (uremia) in human beings. While the present invention has been illustrated by certain specific embodiments, these are not intended to limit the scope of the invention.
