Abstract:
Novel compounds of structural formula (I) are disclosed. As modulators of the Cannabinoid-1 (CB1) receptor, these compounds are useful in the treatment, prevention and suppression of diseases mediated by the CB1 receptor. As such, compounds of the present invention are useful as in the treatment, prevention and suppression of psychosis, memory deficits, cognitive disorders, migraine, neuropathy, neuro-inflammatory disorders (e.g., multiple sclerosis, Guillain-Barre syndrome and the inflammatory sequelae of viral encephalitis), cerebral vascular accidents, head trauma, anxiety disorders, stress, epilepsy, Parkinson&#39;s disease, and schizophrenia. The compounds are also useful for the treatment of substance abuse disorders, particularly to opiates, alcohol, and nicotine. The compounds are also useful for the treatment of obesity or eating disorders associated with excessive food intake and complications associated therewith.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    Marijuana ( Cannabis satiha  L.) and its derivatives have been used for centuries for medicinal and recreational purposes. A major active ingredient in marijuana and hashish has been determined to be Δ 9 -tetrahydrocannabinol (Δ 9 -THC). Detailed research has revealed that the biological action of Δ 9 -THC and other members of the cannabinoid family occurs through two G-protein coupled receptors termed CB 1  and CB 2 . The CB 1  receptor is primarily found in the central and peripheral nervous systems and to a lesser extent in several peripheral organs. The CB 2  receptor is found primarily in lymphoid tissues and cells. Three endogenous ligands for the cannabinoid receptors derived from arachidonic acid have been identified (anandamide, 2-arachidonoyl glycerol, and 2-arachidonyl glycerol ether). Each is an agonist with activities similar to Δ 9 -THC, including sedation, hypothermia, intestinal immobility, antinociception, analgesia, catalepsy, anti-emesis, and appetite stimulation. 
         [0002]    Excessive exposure to Δ 9 -THC can lead to overeating, psychosis, hypotherimia, memory loss, and sedation. Specific synthetic ligands for the cannabinoid receptors have been developed and have aided in the characterization of the cannabinoid receptors: CP55,940 (J. Pharmacol. Exp. Ther. 1988, 247, 1046-1051); WIN55212-2 (J. Pharmacol. Exp. Ther. 1993, 264, 1352-1363); SR141716A (FEBS Lett. 1994, 350, 240-244; Life Sci. 1995, 56, 1941-1947); and SR144528 (J. Pharmacol. Exp. Ther. 1999, 288, 582-589). The pharmacology and therapeutic potential for cannabinoid receptor ligands has been reviewed (Exp. Opin. Ther. Patents 1998, 8, 301-313; Ann. Rep. Med. Chem., A. Doherty, Ed.; Academic Press, NY 1999, Vol. 34, 199-208; Exp. Opin. Ther. Patents 2000, 10, 1529-1538; Trends in Pharma. Sci. 2000, 21, 218-224). There is at least one CB 1  modulator characterized as an inverse agonist or an antagonist, N-(1-piperidinyl)-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methylpyrazole-3-carboxamide (SR141716A), in clinical trials for treatment of eating disorders. 
         [0003]    Hitherto, several classes of CB 1  modulators are known. U.S. Pat. Nos. 5,624,941 and 6,028,084, PCT Publication Nos. WO98/43636 and WO98/43635, and European Patent Application No. EP-658546 disclose substituted pyrazoles having activity against the cannabinoid receptors. PCT Publication Nos. WO98/31227 and WO98/41519 also disclose substituted pyrazoles having activity against the cannabinoid receptors. PCT Publication Nos. WO98/37061, WO00/10967, and WO00/10968 disclose diaryl ether sulfonamides having activity against the cannabinoid receptors. PCT Publication Nos. WO97/29079 and WO99/02499 disclose alkoxy-isoindolones and alkoxy-quinolones as having activity against the cannabinoid receptors. U.S. Pat. No. 5,532,237 discloses N-benzoyl-indole derivatives having activity against the cannabinoid receptors. U.S. Pat. No. 4,973,587, U.S. Pat. No. 5,013,837, U.S. Pat. No. 5,081,122, U.S. Pat. No. 5,112,820, and U.S. Pat. No. 5,292,736 disclose aminoacylinidole derivatives as having activity against the cannabinoid receptors. PCT Publication No. WO03/027076 discloses 1H-imidazole derivatives having CB 1  agonist, CB 1  partial agonist or CB 1  antagonist activity. PCT Publication No. WO03/026648 discloses 4,5-dihydro-1H-pyrazole derivatives having potent CB 1 -antagonist activity. US Publication No. US 2003/0114495 discloses substituted imidazoles as cannabinoid receptor modulators. US Publication No. US 2003/0119810 discloses pharmaceutical compositions containing 3-aminoazelidine derivatives possessing a high affinity for CB 1  receptors. 
         [0004]    [4-(2,3-dihydro-indole-1-sulfonyl)-phenyl]-(4-phenyl-piperazin-1-yl)-methanone RN 439128-75-3, [4-(2,3-dihydro-indole-1-sulfonyl)-phenyl]-morpholin-4-yl-methanone RN394228-83-2, and [4-(2,3-dihydro-indole-1-sulfonyl)-phenyl]-piperidin-1-yl-methanone RN 394228-85-4 are found in the CA database. 
         [0005]    There still remains a need for potent low molecular weight CB 1  modulators that have pharmacokinetic and pharmacodynamic properties suitable for use as human pharmaceuticals.

         [0179]    “Prevention” (of obesity) refers to preventing obesity from occurring if the treatment is administered prior to the onset of the obese condition. Moreover, if treatment is commenced in already obese subjects, such treatment is expected to prevent, or to prevent the progression of, the medical sequelae of obesity, such as, e.g., arteriosclerosis, Type II diabetes, polycystic ovarian disease, cardiovascular diseases, osteoarthritis, dermatological disorders, hypertension, insulin resistance, hypercholesterolemia, hypertriglyceridemia, and cholelithiasis. 
         [0180]    “Solvate” means a physical association of a compound of this invention with one or more solvent molecules. This physical association includes hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. “Solvate” encompasses both solution-phase and isolable solvates. Exemplary solvates include hydrates, ethanolates, methanolates, and the like. 
         [0181]    “Substance abuse disorders” includes substance dependence or abuse with or without physiological dependence. The substances associated with these disorders are: alcohol, amphetamines (or amphetamine-like substances), caffeine, cannabis, cocaine, hallucinogens, inhalants, nicotine, opioids, phencyclidine (or phencyclidine-like compounds), sedative-hypnotics or benzodiazepines, and other (or unknown) substances and combinations of all of the above.

         [0182]    “Therapeutically effective amount” means the amount the compound of structural formula I that will elicit the biological or medical response of a tissue, system, animal or human that is being sought by the researcher, veterinarian, medical doctor or other clinician. 
         [0183]    “Treatment” or “treating” (of obesity) refers to reducing the BMI of the mammal and in certain cases where it is desirable for weight loss. The treatment or treating suitably results in a reduction in food or calorie intake by the mammal. 
         [0184]    The symbol “         ” or “{tilde over ( )}” in a molecular structure indicates the position of attachment for that particular substituent. 
         [0185]    When any variable (e.g., R 1 , R d , etc.) occurs more than one time in any constituent or in formula I, its definition on each occurrence is independent of its definition at every other occurrence. Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds. In choosing compounds of the present invention, one of ordinary skill in the art will recognize that the various substituents, i.e. R 1 , R 2 , etc., are to be chosen in conformity with well-known principles of chemical structure connectivity. 
         [0186]    Under standard nomenclature used throughout this disclosure, the terminal portion of the designated side chain is described first, followed by the adjacent functionality toward the point of attachment. For example, an arylcarbonylaminoalkyl substituent is equivalent to aryl-C(O)—NH-alkyl-. 
         [0187]    Compounds of Formula I may contain one or more asymmetric centers and can thus occur as racemates and racemic mixtures, single enantiomers, diastereomeric mixtures and individual diastereomers. The present invention is meant to comprehend all such isomeric forms of the compounds of Formula I. 
         [0188]    Some of the compounds described herein may exist with different points of attachment of hydrogen, referred to as tautomers. Such an example may be a ketone and its enol form known as keto-enol tautomers. The individual tautomers as well as mixture thereof are encompassed with compounds of Formula I. 
         [0189]    Compounds of the Formula I may be separated into diastereoisomeric pairs of enantiomers by, for example, fractional crystallization from a suitable solvent, for example MeOH or ethyl acetate or a mixture thereof. The pair of enantiomers thus obtained may be separated into individual stereoisomers by conventional means, for example by the use of an optically active amine as a resolving agent or on a chiral HPLC column. 
         [0190]    Alternatively, any enantiomer of a compound of the general Formula I may be obtained by stereospecific synthesis using optically pure starting materials or reagents of known configuration. 
         [0191]    It is generally preferable to administer compounds of the present invention as enantiomerically pure formulations. Racemic mixtures can be separated into their individual enantiomers by any of a number of conventional methods. These include chiral chromatography, derivatization with a chiral auxiliary followed by separation by chromatography or crystallization, and fractional crystallization of diastereomeric salts. 
         [0192]    The present invention also provides novel crystalline forms of the compounds of formula (I). Novel crystalline forms may be prepared by crystallization under controlled conditions. Crystallization from a solution and slurrying techniques are contemplated to be within the scope of the present process. In practice, a number of factors can influence the form obtained, including temperature, solvent composition and also optional seeding. Seed crystals can be obtained from previous synthesis of the compound in which crystals were isolated. 
         [0193]    A number of methods are available to characterize crystalline forms of organic compounds. For example, methods include differential scanning calorimetry, solid state NMR spectrometry, infra-red spectroscopy, and X-ray powder diffraction. Among these X-ray powder diffraction and solid state NMR spectroscopy are very useful for identifying and distinguishing between crystalline forms. 
         [0194]    It will be understood that, as used herein, references to the compounds of Formula I are meant to also include the pharmaceutically acceptable salts. 
         [0195]    Compounds of this invention are modulators of the CB1 receptor and as such are useful for the prevention and treatment of disorders or diseases associated with the CB1 receptor. Accordingly, another aspect of the present invention provides a method for the treatment (including prevention, alleviation, amelioration or suppression) of diseases or disorders or symptoms mediated by CB1 receptor binding and subsequent cell activation, which comprises administering to a mammal an effective amount of a compound of Formula I. Such diseases, disorders, conditions or symptoms are, for example, but not limited to, psychosis, memory deficits, cognitive disorders, migraine, neuropathy, anxiety disorders, depression, stress, epilepsy, Parkinson&#39;s disease, schizophrenia, substance use disorders, particularly to opiates, alcohol, and nicotine, obesity, and eating disorders associated with excessive food intake. See DSM-IV-TR,  Diagnostic and Statistical Manual of Mental Disorders. Revised,  4 th  Ed., Text Revision (2000). See also DSM-IV,  Diagnostic and Statistical Manual of Mental Disorders  4 th  Ed., (1994). The DSM-IV and DSM-IV-TR were prepared by the Task Force on Nomenclature and Statistics of the American Psychiatric Association, and provides descriptions of diagnostic categories. The skilled artisan will recognize that there are alternative nomenclatures, nosologies, and classification systems for pathologic psychological conditions and that these systems evolve with medical scientific progress. 
         [0196]    The obesity herein may be due to any cause, whether genetic or environmental. Examples of disorders that may result in obesity or be the cause of obesity include overeating and bulimia, polycystic ovarian disease, craniopharyngioma, the Prader-Willi Syndrome, Frohlich&#39;s syndrome, Type II diabetes, GH-deficient subjects, normal variant short stature, Turner&#39;s syndrome, and other pathological conditions showing reduced metabolic activity or a decrease in resting energy expenditure as a percentage of total fat-free mass, e.g, children with acute lymphoblastic leukemia. In addition, the compound of formula (I) can be used to ameliorate weight gain, whether or not the associated weight gain can be classified as clinically obese. 
         [0197]    The method of treatment of this invention comprises a method of modulating the CB1 receptor and treating CB1 receptor mediated diseases by administering to a patient in need of such treatment a non-toxic therapeutically effective amount of a compound of this invention that selectively antagonizes the CB1 receptor in preference to the other CB or G-protein coupled receptors. 
         [0198]    “Neutral antagonists” are ligands without intrinsic activity, i.e. they do not influence the receptor&#39;s own activity (constitutive receptor activity) and prevent competitively the binding of an agonist (often endogenous) to the receptor. 
         [0199]    “Inverse agonists” are ligands with negative intrinsic activity, they inhibit the receptor&#39;s own activity (constitutive receptor activity) shifting the equilibrium of the receptor conformation to its inactive state. 
         [0200]    There is evidence suggesting that CB1 receptor ligands act as either neutral antagonists or inverse agonists; these ligands will reduce endocannabinoid neurotransmission through CB1 receptors either by competitive receptor antagonism or by receptor inactivation, respectively. 
         [0201]    Compounds of formula Ia (i.e., compounds of Formula I wherein

         [0202]    In Scheme 1, Step a involves the introduction of R 1 -substitution at the 3-position on the indole moiety of compound (1), (IIa) or (IIc) (wherein Y is I, Br, B(OH) 2 , 
         [0000]    
       
                 
         
             
             
         
       
     
         [0000]    or SnMe 3 ) under standard conditions employed for palladium mediated cross-coupling reactions. For example, a 3-haloindole of formula (1), (IIa), or (IIc) is reacted with a suitable aryl boronic acid (Suzuki-type) or with a suitable aryl stannane (Stille-type), as generally described in Handbook of Palladium Catalyzed Organic Reactions, Malleron. J.-L.; Fiaud, J.-C.; Legros, J.-Y.; Academic Press, USA, 1997, p. 23-47. It is understood by one of ordinary skill in the art that, in general, an aryl boronic ester can be used in place of the aryl boronic acid in the palladium cross-coupling reactions described herein. By way of illustration, the aryl boronic acids include, but are not limited to, the following: 
         [0000]    
       
                 
         
             
             
         
       
     
         [0000]    More specifically, compound (1), (IIa) or (IIc) (Y is I or Br) and the suitable aryl boronic acid or the suitable aryl boronic ester, along with a base (e.g., aqueous sodium carbonate) and a catalyst (e.g., [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex) are dissolved in a suitable solvent such as dichloromethane, and the mixture is heated. Aqueous work-up and chromatographic purification affords the desired compound (2), (IIb) or (Ia). More specifically, in the Stille-type reaction, a 3-iodoindole compound (1), (IIa) or (IIc) is combined with an aryl stannane (e.g., 2-tributylstannyl pyrazine, 3-tributylstannylpyridine, 2-tributylstannylpyridine) and a catalyst (e.g., tetrakis(triphenylphosphine)Pd(0)) in an appropriate solvent (e.g., DMF) and heated. After an aqueous work-up, compound (2), (Ia) or (IIb) is isolated by chromatographic purification. 
         [0203]    Alternatively, a 3-haloindole compound (1), (IIa) or (IIc) is subjected to a palladium-mediated coupling with an olefin (e.g., cyclopentene) or an α,β-unsaturated ketone or ester (Heck-type), then the resulting intermediate is hydrogenated to provide the desired compound (2), (IIb) or (Ia). (see generally Handbook of Palladium Catalyzed Organic Reactions, Malleron, J.-L.; Fiaud, J.-C.; Legros, J.-Y.; Academic Press, USA 1997 p. 61-71.) More specifically, a 3-iodoindole compound (1), (IIa) or (IIc) is combined with an olefin and a catalyst (e.g., palladium (II) acetate) along with tetrabutylammonium chloride and a base (e.g., potassium acetate) and the resulting mixture heated. After an aqueous work-up, the intermediate product is isolated by chromatographic purification, then subjected to hydrogenation to remove the resulting olefin, thereby providing the desired compound (2), (Ia), or (IIb). 
         [0204]    Alternatively, a 3-haloindole compound (1), (IIa) or (IIc) is subjected to a metal halogen exchange with a reagent such as cyclopentyl magnesium bromide and then treated with a ketone such as tetrahydro-4H-pyran-4-one. The resulting alcohol is isolated and treated with a reducing agent (e.g., triethylsilane and TFA) to provide the desired compound (2), (Ia) or (IIb). 
         [0205]    Alternatively, a compound (1), (IIa), or (IIc) when Y is B(OH) 2 ,

         [0000]    or SnMe 3  is reacted via a palladium-mediated coupling employing a suitable aryl halide in a manner analogous procedure set forth above. By way of illustration, suitable aryl halides include, but are not limited to, 5-bromo-2-methoxy pyridine, 5-bromo-2-fluoro-pyridine, 2-bromo-5-chloro-thiophene, 4-bromo-isoquinoline, 2-bromo-5-chloro-thiophene, 3-bromo-toluene, 4-bromo-toluene, 1-bromo-3-methoxy-phenyl, 6-bromo-quinoline, 1-bromo-4-dimethylamino-phenyl, 1-bromo-3-fluoro-pyridine, 2-bromo-pyrimidine and 5-bromo-pyrimidine. 
         [0206]    In scheme 1 step b, a sulfonamide of formula (Ia), (IIa), (IIb) or (IIc) is prepared via treatment of the appropriate indole of formula (1) or (2) with the requisite sulfonyl chloride of formula (3) or (4) in the presence of a base under standard conditions. More specifically, the indole of formula (1) or (2) and the sulfonyl chloride of formula (3) or (4) are combined with a base (e.g., diisopropylethylamine, potassium tertbutoxide or sodium hydride) in an appropriate solvent (e.g., N,N-dimethylformamide, dioxane or tetrahydrofuran). Alternatively, the indole of formula (1) or (2) and sulfonyl chloride of formula (3) or (4) are combined with a catalyst (e.g., DMAP or 4-pyrrolidin-1-yl-pyridine) with or without a base in an appropriate solvent (e.g., N,N-dimethylformamide, dioxane or acetonitrile). An aqueous work-up and chromatographic purification affords compound (Ia), (IIa), (IIb) or (IIc). 
         [0207]    In Scheme 1, step c, the conversion of an ester of formula (IIb) to an amide of formula (Ia) is achieved under standard conditions via the carboxylic acid or acid chloride, as referenced in Comprehensive Organic Transformations, R. C. Larock VCH Publishers Inc, New York, N.Y. 1989. p. 972-976. More Specifically, the ester of formula (IIb) is hydrolyzed to the acid in the presence of a base (e.g., sodium hydroxide), converted to the acid chloride with reagents such as oxalyl chloride, and then treated with the requisite amine in the presence of a base (e.g., triethylamine) to form the compound (Ia). Alternatively the acid is coupled with the amine using a coupling reagent (e.g., EDC, BOP or PyBOP) with or without a catalyst (e.g., NHS). After an aqueous work-up, the products are isolated by chromatographic purification to yield the compound (Ia). 
         [0208]    Compounds of formula (Ia) can also be prepared according to the processes illustrated in Scheme 2. 
         [0000]    
       
                 
         
             
             
         
       
     
         [0209]    In Scheme 2, step a, direct alkylation of a compound (5), (IId) or (IIe) is achieved via heating with a ketone (e.g., cyclohexanone or 2-methoxycyclohexanone) and a base (e.g., potassium hydroxide). The resulting olefin is hydrogenated to form a compound of formula (2), (IIb), or (Ia) (see, e.g.,  J. Med. Chem . (1997), 40, 250). Alternatively, direct alkylation of a compound of formula (5), (IId), (IIe) is achieved under protic or lewis acid conditions with an alcohol (e.g., tert-butyl alcohol) or alkyl bromide (e.g., as described in  J. Org. Chem . (2002), 67, 2705). Alternatively, conjugate addition to an α,β-unsaturated ketone is achieved in the presence of indium tribromide and isopropylamine in solvents such as dichloromethane, as described in  J. Org.

More specifically, 3-bromoindole N-protected with a triisopropylsilanyl group is combined with an amine (e.g., piperidine, morphline, or 1-methyl piperazine), a catalyst (e.g., tris(dibenzylideneacetone)dipalladium(0) chloroform adduct and 2-dicyclohexylphosphino-2′-(N,N-dimethylamino)biphenyl), and a base (e.g., lithium bis(trimethylsilyl)amide), and the mixture heated in an appropriate solvent (e.g., THF). The resulting intermediate is deprotected with tetrabutyl ammonium fluoride, after which an aqueous work-up and chromatographic purification yields isolated compound (2a).

         [0367]    Add in a 22-L 3-neck round bottom equipped with overhead stirrer, reflux condenser, and thermometer, N,N-dimethylacetamide (DMAC, 6 L), 2,5-dichloropyridine (347.0 g, 2.34 mol), zinc cyanide (138.0 g, 1.17 mol), bis(diphenylphosphino)dipalladium II CH 2 Cl 2  complex (DPPF, 20.8 g, 0.02 mol), and zinc dust (1.6 g, 0.02 mol). Slowly warm the reaction mixture to 160° C. As the temperature reaches 160° C., an exotherm (controllable) may result and the internal temperature may rise to 180-185° C. Remove the heat from the dark solution and cool the mixture slowly cool to room temperature. Extract the bulk reaction mixture by taking 2 L of the dark solution, diluting with brine (2 L), filtering over celite, and addition of ethyl acetate (4 L). Repeat the process 3 times to extract all material, and dry the combined organics over magnesium sulfate. Cautious concentration at 25-30° C. might give a dark liquid. (Note: Product volatility maybe observed at higher temperatures so the temperature upon concentration is kept low in all steps.) Stir the liquid and add water (5 L), resulting in a solid After 1 h, filter, and back-wash with water (2 L). Dry the filter cake to give 215 g of crude product. Extract the aqueous filtrate with ethyl ether (8 L). Dry the organics over magnesium sulfate and concentrate to provide 51 g of crude product. Combine with the 215 g lot and purify by chromatography over silica gel (biotage 150; eluting with 5% ethyl acetate in hexanes increasing to 10% ethyl acetate in hexanes) to provide a white solid of pure title compound (193 g, 59%);  1 H NMR (CDCl 3 ) δ 8.68 (d, J=2.0 Hz, 1H), 7.84 (dd, J=2.7, 8.6 Hz, 1H), 7.66 (d, J=8.3 Hz, 1H).

Extract the filtrate with water (6 L) and ethyl ether (3×5 L). Combine the organics and back-extract with water (8 L) and dry over magnesium sulfate. Concentrate at 25-30° C. to give an oily semi-solid, 193 g. Chromatograph over flash silica gel (5% ethyl acetate in hexanes gradually increasing to 10% ethyl acetate in hexanes) to provide the title compound as a white solid.

         [0617]    In this test, the IC 50 of the compounds of formula (I) is less than or equal to 5 μM. 
         [0618]    The utilities of the present compounds in treating or preventing diseases or disorders may be demonstrated in animal disease models that have been reported in the literature. The following are examples of such animal disease models: a) suppression of food intake and resultant weight loss in rats (Life Sciences 1998, 63, 113-117); b) reduction of sweet food intake in marmosets (Behavioural Pharm. 1998, 9, 179-191); c) reduction of sucrose and ethanol intake in mice (Psychopharm. 1997, 132, 104-106); d) increased motor activity and place conditioning in rats (Psychopharm. 1998, 135, 324-332; Psychopharmacol 2000, 151: 25-30); e) spontaneous locomotor activity in mice (J. Pharm. Exp. Ther. 1996, 277, 586-594); and f) reduction in opiate self-administration in mice (Sci. 1999, 283, 401-404). 
         [0619]    The administration of the compound of structural formula I in order to practice the present methods of therapy is carried out by administering an effective amount of the compound of structural formula I to the patient in need of such treatment or prophylaxis. The need for a prophylactic administration according to the methods of the present invention is determined via the use of well-known risk factors. The effective amount of an individual compound is determined, in the final analysis, by the physician in charge of the case, but depends on factors such as the exact disease to be treated, the severity of the disease and other diseases or conditions from which the patient suffers, the chosen route of administration other drugs and treatments which the patient may concomitantly require, and other factors in the physician&#39;s judgment. 
         [0620]    The magnitude of prophylactic or therapeutic dose of a compound of Formula I will, of course, vary with the nature of the severity of the condition to be treated and with the particular compound of Formula I and its route of administration. It will also vary according to the age, weight and response of the individual patient. In general, the daily dose range lie within the range of from about 0.001 mg to about 100 mg per kg body weight of a mammal, preferably 0.01 mg to about 50 mg per kg, and most preferably 0.1 to 10 mg per kg, in single or divided doses. On the other hand, it may be necessary to use dosages outside these limits in some cases. 
         [0621]    For use where a composition for intravenous administration is employed, a suitable dosage range is from about 0.001 mg to about 25 mg (preferably from 0.01 mg to about 1 mg) of a compound of Formula I per kg of body weight per day and for cytoprotective use from about 0.1 mg to about 100 mg (preferably from about 1 mg to about 100 mg and more preferably from about 1 mg to about 10 mg) of a compound of Formula I per kg of body weight per day. 
         [0622]    In the case where an oral composition is employed, a suitable dosage range is, e.g. from about 0.01 mg to about 100 mg of a compound of Formula I per day, preferably from about 0.1 mg to about 10 mg per day. For oral administration, the compositions are preferably provided in the form of tablets containing from 0.01 to 1,000 mg, preferably 0.01, 0.05, 0.1, 0.5, 1.0, 2.5, 5.0, 10.0, 15.0, 20.0, 25.0, 30.0, 40.0, 50.0 or 1000.0 milligrams of the active ingredient for the symptomatic adjustment of the dosage to the patient to be treated. 
         [0623]    For the treatment of diseases of the eye, ophthalmic preparations for ocular administration comprising 0.001-1% by weight solutions or suspensions of the compounds of Formula I in an acceptable ophthalmic formulation may be used. 
         [0624]    Another aspect of the present invention provides pharmaceutical compositions which comprises a compound of Formula I and a pharmaceutically acceptable carrier. The term “composition”, as in pharmaceutical composition, is intended to encompass a product comprising the active ingredient, preferably present in pharmaceutically effective amounts, and the inert ingredient(s) (pharmaceutically acceptable excipients) that make up the carrier, as well as any product which results, directly or indirectly, from combination, complexation or aggregation of any two or more of the ingredients, or from dissociation of one or more of the ingredients, or from other types of reactions or interactions of one or more of the ingredients. Accordingly, the pharmaceutical compositions of the present invention encompass any composition made by admixing a compound of Formula I and pharmaceutically acceptable excipients. 
         [0625]    Any suitable route of administration may be employed for providing a mammal, especially a human with an effective dosage of a compound of the present invention. For example, oral, rectal, topical, parenteral, ocular, pulmonary, nasal, and the like may be employed. Dosage forms include tablets, troches, dispersions, suspensions, solutions, capsules, creams, ointments, aerosols, suppositories and the like. 
         [0626]    The pharmaceutical compositions of the present invention comprise a compound of Formula I as an active ingredient or a pharmaceutically acceptable salt thereof, and may also contain a pharmaceutically acceptable carrier and optionally other therapeutic ingredients. By “pharmaceutically acceptable” it is meant the carrier, diluent or excipient must be compatible with the other ingredients of the formulation and not deleterious to the recipient thereof. In particular, the term “pharmaceutically acceptable salts” refers to salts prepared from pharmaceutically acceptable non-toxic bases or acids including inorganic bases or acids and organic bases or acids. The compound may be present in crystalline form or may be incorporated into the pharmaceutical composition as an amorphous solid. Alternatively, the compound may be rendered partially or totally amorphous by the manufacturing process. 
         [0627]    The compositions include compositions suitable for oral, rectal, topical, parenteral (including subcutaneous, intramuscular, and intravenous), ocular (ophthalmic), pulmonary (aerosol inhalation), or nasal administration, although the most suitable route in any given case will depend on the nature and severity of the conditions being treated and on the nature of the active ingredient. They may be conveniently presented in unit dosage form and prepared by any of the methods well-known in the art of pharmacy. 
         [0628]    For administration by inhalation, the compounds of the present invention are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or nebulizers. The compounds may also be delivered as powders which may be formulated and the powder composition may be inhaled with the aid of an insufflation powder inhaler device. The preferred delivery systems for inhalation are metered dose inhalation (MDI) aerosol, which may be formulated as a suspension or solution of a compound of Formula I in suitable propellants, such as fluorocarbons or hydrocarbons and dry powder inhalation (DPI) aerosol, which may be formulated as a dry powder of a compound of Formula I with or without additional excipients. 
         [0629]    Suitable topical formulations of a compound of formula I include transdermal devices, aerosols, creams, ointments, lotions, dusting powders, and the like. Topical preparations containing the active drug component can be admixed with a variety of carrier materials well known in the art such as, e.g., alcohols, aloe vera gel, allantoin, glycerine, vitamin A and E oils, mineral oil, PPG2 myristyl propionate, and the like. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen. 
         [0630]    The compounds of the present invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles and multilamellar vesicles. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine or phosphatidylcholines. 
         [0631]    The compounds of the present invention may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamide phenol, polyhydroxyethylasparamidepheon, or polyethyleneoxidepolylysine substituted with palmitoyl residues. Furthermore, the compounds of the present invention may be coupled to a class of biodegradable polymers useful in achieving controlled release of a drug, for example, polylactic acid, polyepsilon caprolactone, polyhydroxybutyric acid, polyorthoesters, polyacetals, polydihydropyrans, polycyanoacrylates and cross-linked or amphipathic block copolymers of hydrogels. 
         [0632]    Compounds of the present invention may also be delivered as a suppository employing bases such as cocoa butter, glycerinated gelatin, hydrogenated vegetable oils, mixtures of polyethylene glycols of various molecular weights and fatty acid esters of polyethylene glycol. 
         [0633]    In practical use, the compounds of Formula I can be combined as the active ingredient in intimate admixture with or solubilization in a pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier may take a wide variety of forms depending on the form of preparation desired for administration, e.g., oral or parenteral (including intravenous). In preparing the compositions for oral dosage form, any of the usual pharmaceutical media may be employed, such as, for example, water, glycols, simple oils, fractionated or chemically-modified glycerides, polyoxyethylene-polyoxypropylene co-polymers, alcohols, surface active agents, flavoring agents, preservatives, coloring agents and the like in the case of oral liquid preparations, such as, for example, suspensions, elixirs and solutions; or carriers such as starches, sugars, microcrystalline cellulose, diluents, granulating agents, lubricants, binders, disintegrating agents and the like in the case of oral solid preparations such as, for example, powders, capsules and tablets, with the solid oral preparations being preferred over the liquid preparations. The carrier may possess special properties for controlling or modifying the release and subsequent absorption profile of the drug substance, said properties including but not limited to self-emulsification, or controlled disintegration, dissolution or solubilization in vivo. Because of their ease of administration, tablets and capsules represent the most advantageous oral dosage unit form in which case solid pharmaceutical carriers are obviously employed. If desired, tablets may be coated by standard aqueous or nonaqueous techniques. 
         [0634]    In addition to the common dosage forms set out above, the compounds of Formula I may also be administered by controlled release means and/or delivery devices such as those described in U.S. Pat. Nos. 3,845,770; 3,916,899; 3,536,809; 3,598,123; 3,630,200 and 4,008,719. 
         [0635]    Pharmaceutical compositions of the present invention suitable for oral administration may be presented as discrete units such as capsules, cachets or tablets each containing a predetermined amount of the active ingredient, as a powder or granules or as a solution or a suspension in an aqueous liquid, a non-aqueous liquid, an oil-in-water emulsion or a water-in-oil liquid emulsion. Such compositions may be prepared by any of the methods of pharmacy but all methods include the step of bringing into association the active ingredient with the carrier which constitutes one or more necessary ingredients. In general, the compositions are prepared by uniformly and intimately admixing the active ingredient with liquid carriers or finely divided solid carriers or both, and then, if necessary, shaping the product into the desired presentation. For example, a tablet may be prepared by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine, the active ingredient in a free-flowing form such as powder or granules, optionally mixed with a binder, lubricant, inert diluent, surface active or dispersing agent. Molded tablets may be made by molding in a suitable machine, a mixture of the powdered compound moistened with an inert liquid diluent. Hard or soft gelatin capsules may be prepared by filling either with dry powder or granule formulations or by filling with a liquid formulation compatible with the capsule shell. Desirably, each tablet contains from 0.01 to 500 mg, particularly 0.01, 0.05, 0.1, 0.5, 1.0, 2.5, 3.0, 5.0, 6.0, 10.0, 15.0, 25.0, 50.0, 75, 100, 125, 150, 175, 180, 200, 225, and 500 milligrams of the active ingredient for the symptomatic adjustment of the dosage to the patient to be treated. And each cachet or capsule contains from about 0.01 to 500 mg, particularly 0.01, 0.05, 0.1, 0.5, 1.0, 2.5, 3.0, 5.0, 6.0, 10.0, 15.0, 25.0, 50.0, 75, 100, 125, 150, 175, 180, 200, 225, and 500 milligrams of the active ingredient for the symptomatic adjustment of the dosage to the patient to be treated. 
         [0636]    Exemplifying the invention is a pharmaceutical composition comprising any of the compounds described above and a pharmaceutically acceptable carrier. Also exemplifying the invention is a pharmaceutical composition made by combining any of the compounds described above and a pharmaceutically acceptable carrier. An illustration of the invention is a process for making a pharmaceutical composition comprising combining any of the compounds described above and a pharmaceutically acceptable carrier. 
         [0637]    The dose may be administered in a single daily dose or the total daily dosage may be administered in divided doses of two, three or four times daily. Furthermore, based on the properties of the individual compound selected for administration and/or the characteristics of the dosage form (i.e., modified release), the dose may be administered less frequently, e.g., weekly, twice weekly, monthly, etc. The unit dosage may be correspondingly larger for the less frequent administration. 
         [0638]    When administered via transdermal routes or through a continual intravenous solution, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen. 
         [0639]    The following are examples of representative pharmaceutical dosage forms for the compounds of Formula I:
