BACKGROUND OF THE INVENTION
Immunoregulatory abnormalities have been shown to exist in a wide variety of "autoimmune" and chronic inflammatory diseases, including systemic lupus erythematosis, chronic rheumatoid arthritis, type I and II diabetes mellitus, inflammatory bowel disease, biliary cirrhosis, uveitis, multiple sclerosis and other disorders such as Crohn's disease, ulcerative colitis, bullous pemphigoid, sarcoidosis, psoriasis, ichthyosis, and Graves ophthalmopathy. Although the underlying pathogenesis of each of these conditions may be quite different, they have in common the appearance of a variety of autoantibodies and self-reactive lymphocytes. Such self-reactivity may be due, in part, to a loss of the homeostatic controls under which the normal immune system operates.
Similarly, following a bone-marrow or an organ transplantation, the host lymphocytes recognize the foreign tissue antigens and begin to produce antibodies which lead to graft rejection.
One end result of an autoimmune or a rejection process is tissue destruction caused by inflammatory cells and the mediators they release. Antiinflammatory agents such as NSAID's and corticosteroids act principally by blocking the effect or secretion of these mediators but do nothing to modify the immunologic basis of the disease. On the other hand, cytotoxic agents such as cyclophosphamide, act in such a nonspecific fashion that both the normal and autoimmune responses are shut off. Indeed, patients treated with such nonspecific immunosuppressive agents are as likely to succumb from infection as they are from their autoimmune disease.
Cyclosporin A which was approved by the US FDA in 1983 is currently the leading drug used to prevent rejection of transplanted organs. The drug acts by inhibiting the body's immune system from mobilizing its vast arsenal of natural protecting agents to reject the transplant's foreign protein. Though cyclosporin A is effective in fighting transplant rejection, it is nephrotoxic and is known to cause several undesirable side effects including kidney failure, abnormal liver function and gastrointestinal discomfort.
Newer, safer drugs exhibiting less side effects are constantly being searched for in the field.
The 23-membered tricyclo-macrolide immunosuppressant, tacrolimus, FR-900506, FK-506, ##STR3## (17-allyl-1,14-dihydroxy-12-[2'-(4"-hydroxy-3"-methoxycyclohexyl)-1'-methylvinyl]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo-[22.3.1.0.sup.4,9 ]octacos-18-ene-2,3,10,16-tetraone) and related compounds which were isolated and characterized by Tanaka, Kuroda, and co-workers at Fujisawa Pharmaceutical Co. in Japan, see J. Am. Chem. Soc., 1987, 109, 5031, and U.S. Pat. No. 4,894,366, issued Jan. 16, 1990) have been shown to possess exceptional immunosuppressive activity. Fujisawa United States patents (U.S. Pat. No. 4,929,611, issued May 29, 1990, U.S. Pat. No. 4,956,352, issued Sep. 11, 1990 and U.S. Pat. No. 5,110,811, issued May 5, 1992) disclose the use of FK-506-type compounds in treating resistance to transplantation. In particular, the compound FR-900506 has been reported to be 100 times more effective than cyclosporin in the supression of in vitro immune systems (J. Antibiotics 1987, 40, 1256). In addition, these compounds are reputed to possess topical activity in the treatment of inflammatory and hyperproliferative skin diseases and cutaneous manifestations of immunologically-mediated illnesses (EPO Pub. No. 0,315,978).
The compound FK-506 and related compounds further have been suggested to be useful in the treatment of obstructive airways disease, particularly asthma (PCT Publication WO 90/14826), male pattern alopecia or alopecia senilis (EPO Publication No. 0,423,71.4), rheumatoid arthitis (C. Arita, et al., Clinical exp. Immunol., 1990, 82, 456-461; N. Inamura, et al., Clin. Immunol. Immunopathol. 1988, 46, 82-90), recent-onset diabetes (N. Murase, et al., Diabetes, 1990, 39, 1584-86; N. Murase, et al., Lancet, 1990, 336, 373-74), posterior uveitis (H. Kawashima, Invest. Ophthalmol. Vis. Sci., 1988, 29, 1265-71), hepatic injury associated with ischemia (M. Sakr, et al., Life Sci., 1990, 427, 687-91) allergic encephalomyelitis (K, Deguchi, et al., Brain Nerve, 1990, 42, 391-97), glomerulonephritis (J. McCauley, et al., Lancet, 1990, 335, 674), systemic lupus erythematosus (K. Takabayashi, et al., Clin. Immunol. Immunopathol., 1989, 51, 110-117) multidrug resistance (M. Naito, et al., Cancer Chemother. Pharmacol., 1992, 29, 195-200), inflammation of mucosa and blood vessels (PCT Publication WO 92/17754), cytomegalovirus infection (UK Publication GB 2,247,620A), and idiopathic thrombocytophenic purpura and Basedow's disease (PCT Publication WO 91/19495).

The compounds of the present invention have asymmetric centers and this invention includes all of the optical isomers and mixtures thereof.
In addition compounds with carbon--carbon double bonds may occur in Z- and E- forms with all isomeric forms of the compounds being included in the present invention.
When any variable (e.g., alkyl, aryl, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.10 etc.) occurs more than one time in any variable or in Formula I, its definition on each ocurrence is independent of its definition at every other occurrence.
As used herein, the term "alkyl" includes those alkyl groups of a designated number of carbon atoms of either a straight, branched, or cyclic configuration. Examples of "alkyl" include methyl, ethyl, propyl, isopropyl, butyl, sec-and tert-butyl, pentyl, hexyl, heptyl, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, norbornyl, and the like. "Alkoxy" represents an alkyl group of indicated number of carbon atoms attached through an oxygen bridge, such as methoxy, ethoxy, propoxy, butoxy and pentoxy.
"Alkenyl" is intended to include hydrocarbon chains of a specified number of carbon atoms of either a straight- or branched-configuration and at least one unsaturation, which may occur at any point along the chain, such as ethenyl, propenyl, butenyl, pentenyl, dimethylpentyl, and the like, and includes E and Z forms, where applicable; and "heteroarylalkyl" represents heteroaryl groups as herein defined which are attached through a straight or branched chain alkyl group of from one to ten carbon atoms. "Halogen" or "halo", as used herein, means fluoro, chloro, bromo and iodo.
The Ar group may include:
(1) phenyl or naphthyl, which are optionally substituted by from one- to three-members independently selected as defined above, and
(2) heteroaryl, which may include acridine, carbazole, cinnoline, dibenzofuran, dibenzothiophene, quinoxaline, pyrrazole, benzoxazole, indole, imidazole, thiazole, benzothiazole, benzotriazole, furan, benzofuran, benzimidazole, quinoline, isoquinoline, oxazole, pyrazine pyridazine, pyridine, pyrimidine and pyrrole which are optionally substituted.
As will be understood by those skilled in the art, pharmaceutically acceptable salts include, but are not limited to salts with inorganic acids such as hydrochloride, sulfate, phosphate, diphosphate, hydrobromide, and nitrate or salts with an organic acid such as malate, maleate, fumarate, tanrate, succinate, citrate, acetate, lactate, methanesulfonate, p-toluenesulfonate or palmoate, salicylate and stearate. Similarly pharmaceutically acceptable cations include, but are not limited to sodium, potassium, calcium, aluminum, lithium and ammonium (especially ammonium salts with amines of the formula HNR.sup.6 R.sup.7).
In the compounds of Formula I the heteroaryl group may be optionally substituted with X, Y and Z at any available carbon atom or nitrogen atom (if present), but compounds bearing certain of X, Y and Z directly substituted to a nitrogen atom of the heteroaryl ring may be relatively unstable and are not preferred.
The term "heteroaryl" as utilized herein is specifically intended to include the following heteraromatic groups which may include X, Y and Z substitution as indicated and wherein Q is --N(X)--, --O--, --S--, --SO--, or --SO.sub.2 --: ##STR9##

B. Preparation of Compounds Within the Scope of the Present Invention
The starting materials for the prepartion of the compounds of this invention are represented by Formula II: ##STR15## wherein: E is hydrogen or methyl;
W is O or (H, OH);
R.sup.3 is hydrogen, hydroxy, or C.sub.1-6 alkoxy;
R.sup.4 is hydrogen, or R.sub.3 and R.sub.4 taken together form a double bond;
R.sup.5 is methyl, ethyl, propyl or allyl; and
n is 1 or 2.
The production and characterization of compounds of Formula II is well known in the literature (see U.S. Pat. No. 4,894,366, issued Jan. 16, 1990; U.S. Pat. No. 4,929,611, issued May 29, 1990; U.S. Pat. No. 3,244,592, issued Apr. 15, 1966; EPO Publication No. 0,323,042; EPO Publication No. 0,356,399; PBJ Disclosure 63-17884; J. Am. Chem. Soc., 1987, 109, 5031; J. Antibiotics, 1987, 40, 1249, J. Antibiotics, 1988, 41(11), 1592; and J. Antibiotics, 1992, 45(1), 118). Both biological fermentation and synthetic processes may be found. A synthetic route to compounds of Formula II can involve modifications of a route described in J. Am. Chem. Soc., 1989, 111, 1157.
Biological fermentation followed by synthetic modification is presently favored in the an as the method to produce compounds of Formula II. Organisms belonging to the genus Streptomyces such as Streptomyces tsukubaensis, No. 9993 and Streptomyces hygroscopicus, var. ascomycetis, No. 14891 placed in an aqueous nutrient medium will produce desired compounds in isolable amounts. The nutrient medium contains sources of assimilable carbon and nitrogen, preferably under aerobic conditions. Produced in fermentation are four compounds of Formula II, (A) where E is methyl, W is O, R.sup.3 is hydroxyl, R.sup.4 is hydrogen, R.sup.5 is allyl and n is 2; (B) where E is methyl, W is O, R.sup.3 is hydroxyl, R.sup.4 is hydrogen, R.sup.5 is ethyl and n is 2; (C) where E is methyl, W is O, R.sup.3 is hydroxyl, R.sup.4 is hydrogen, R.sup.5 is methyl and n is 2; and (D) where E is methyl W is O, R.sup.3 is hydroxyl, R.sup.4 is hydrogen, R.sup.5 is allyl and n is 1.
A lyophilized sample of the isolated Streptomyces tsukubaensis, No. 9993 was deposited with the Fermentation Research Institute, Agency of Industrial Science and Technology (No. 1-3, Higashi 1-chome, Yatabemachi Tsukuba-gun, Ibaraki Prefecture, Japan) under the deposit number of FERM P-7886 (deposit date: Oct. 5, 1984), and then convened to Budapest Treaty route of the same depository on Oct. 19, 1985 under the new deposit number of FERM BP-927.
Using the four compounds produced in fermentation above, the remaining compounds of Formula II may be easily produced. The allyl of R.sup.5 may be conveniently reduced to propyl by well known methods, for example as described in U.S. Pat. No. 4,894,366. The hydroxy of R.sup.3 may be protected by well known methods, for example as disclosed in EPO Publication No. 0,323,042. Likewise, the hydroxyl at C-4" may also be protected. In addition, the hydroxy of R.sup.3 may be reduced to a hydrogen or eliminated to form a double bond with R.sup.4 (by methods disclosed in U.S. Pat. No. 4,894,366, EPO publication No. 0,323,042 or EPO Publication No. 0,413,532). The carbonyl of W may be reduced to the alcohol by methods disclosed in EPO Publication No. 0,323,042 or by methods disclosed in EPO Publication No. 0,445,975.
The methyl of E as produced may be replaced with hydrogen or demethylated and subsequently protected as desired, if necessary. This demethylation of compounds wherein E is methyl may be carried out in a fermentation reaction using the compounds of Formula II as a feedstock. For instance, compound A named under Formula II above may be demethylated at E above by using the microorganism Actinomycetales ATCC No. 53771 (described in U.S. Pat. No. 4,981,792) or by using the microorganism Streptomyces tsukubaensis, No. 9993 (described in EPO Publication No. 0,353,678). Similarly, compound B named under Formula II above may be demethylated at E above using the microorganism Actinoplanacete sp. ATCC No. 53771 (described in EPO Publication No. 0,349,061). In addition the compound of Formula II wherein E is H, W is O, R.sup.3 is hydroxy, R.sup.4 is hydrogen, R.sup.5 is ethyl and n is 2 may be produced directly by fermentation using the mutant microorganism Streptomyces hygroscopicus sup. ascomyceticus, No. 53855 (being a blocked mutant of Streptomyces hygroscopicus sup. ascomyceticus, No. 14891) (as described in EPO Publication No. 0,388,152). Similarly, the compound of Formula II wherein E is hydrogen, W is O, R.sup.3 is hydroxy, R.sup.4 is hydrogen, R.sup.5 is methyl and n is 2 may be produced directly by fermentation using the mutant microorganism Streptomyces hygroscopicus sup. ascomyceticus, No. 53855 (being a blocked mutant of Streptomyces hygroscopicus sup. ascomyceticus, No. 14891) (EPO Publication No. 0,388,153). The hydroxy of C-3" may be protected by methods similar to those known for the protection of the hydroxyl groups of R.sup.3 and/or C-4", for example as disclosed in U.S. Pat. No. 4,894,366.
Suitable protecting groups for hydroxyl include those groups well known in the art such as: methylthiomethyl, ethylthiomethyl; trisubstituted silyl such as trimethylsilyl, triethylsilyl, tributylsilyl, tri-i-propylsilyl, t-butyldimethylsilyl, tri-t-butylsilyl, methyl-diphenylsilyl, ethyldiphenylsilyl, t-butyldiphenylsilyl, and the like; acyl such as acetyl, pivaloyl benzoyl, 4-methoxybenzoyl, 4-nitrobenzoyl and aliphatic acyl substituted with aromatic group, which are derived from carboxylic acids; and the like.
Compounds A, B, C and D of Formula II, organisms to produce the same, conditions of fermentation, separation techniques, and chemical modification of the products are fully described in U.S. Pat. No. 4,894,366, dated Jan. 16, 1990, U.S. Pat. No. 4,929,611, issued May 29, 1990 and U.S. Pat. No. 5,110,811, issued May 5, 1992.
The novel processes for preparing the novel compounds of the present invention are illustrated as follows, wherein R.sup.1, R.sup.2, R.sup.3, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.10, R.sup.11, E, W and n are as defined above unless otherwise indicated. It will be readily apparent to one of ordinary skill in the art reviewing the synthetic route depicted below that other compounds within Formula I can be synthesized by substitution of appropriate reactants and agents in the synthesis shown below. ##STR16##
Compounds of this invention may be prepared by a method in which pre-formed components (Ar--A--B--) are combined with the appropriate ketone by various olefination procedures.
The ketone precursors are prepared according to procedures described in Schemes A, B and C.
As shown in Reaction Scheme A, a solution of a 4"-hydroxy-3"-methoxy macrolide 1 may be regioselectively osmylated with catalytic, stochiometric or excess quantities of OsO.sub.4 in methylene chloride. The resulting osmylate maybe cleaved to ketone 2 with periodic acid in reasonable yield. Preferably, the osmylation may be conducted catalytically with 4-methylmorpholine-N-oxide, iodosobenzoic acid, and osmium tetroxide
Protection of the C.sub.14 -hydroxyl group (R.sup.3 .dbd.OH) may be accomplished by methods known in the prior an such as by treatment with: 2,6-lutidine and triisopropylsilyl trifluoromethansulfonate in a solution of methylene chloride; 2,6-lutidine; t-butyldimethylsilyl trifluoromethanesulfonate in a solution of methylene chloride; pyridine and acetic anhydride in a solution of methylene chloride; pyridine and benzoyl chloride in a solution of dichloromethane; pyridine and p-nitrobenzoyl chloride in a solution of dichloromethane, imidazole and t-butyldiphenylsilyl chloride in a solution of methylene chloride; and the like. For example, as shown in Reaction Scheme A, ketone 2 may be protected at C.sub.14 as the tri-ethylsilyl ether (TES) by treatment with tri-ethylsilyl trifluoromethanesulfonate in methylene chloride to give macrolide 3. ##STR17##
Several olefination methods have been utilized to prepare compounds of the formula XXI from ketones of general structure XXIII. Peterson olefination [addition of an .alpha.-silyl lithium carbanion to the carbonyl group at -78.degree. C., followed by spontaneous or HF-mediated elimination of the vicinal hydroxyl group and silyl substituent (5% HF in acetonitrile, rt] is an effective method [Peterson, J. Org. Chem. 33, 780 (1968), Magnus, Aldrichchimica Acta, 13, 43-51 (1980)]. A general method for preparing the Peterson-type reagents from aldehydes involves the preparation of .alpha.-stannyl silane reagents, and their reaction with n-Butyl lithium in an aprotic solvent such as THF, diethyl ether or dimethoxyethane (A. G. M. Barrett, J. M. Hill, Tetrahedron Lett. 1991, 32, 3285-3288) [Scheme B, sequence 1]. Another method involves the reaction of aryl carbanions (produced from reaction with t-butyl lithium in a aprotic solvent such as THF at -78.degree. C.) with substituted vinyl silanes [Scheme B, sequence 2].
Stabilized Wittig-type ylid reagents in solvents such as toluene at moderately elevated temperatures (40.degree.-70.degree. C.) are also effective in achieving olefinations [Scheme B, sequence 3].
From these olefination reactions, geometric mixtures (E and Z) are produced with the E isomer predominating. These may be separated by standard chromatography methods. The silyl protecting group for the C.sub.14 hydroxy group (should present) may be removed by stirring the compound in a solution of HF in pyridine.
The reaction sequences described in Reaction Schemes A and B may also be carried out on various structural types of the general structure II. ##STR18##
The 4"- and 14- hydroxyl groups of compound 1 may be both protected by methods known in the art such as by treatment with: 2,6-lutidine and triisopropylsilyl trifluoromethanesulfonate in a solution of methylene chloride; 2,6-lutidine; t-butyldimethylsilyl trifluoromethanesulfonate in a solution of methylene chloride; pyridine and acetic anhydride in a solution of methylene chloride; pyridine and benzoyl chloride in a solution of dichloromethane; pyridine and p-nitrobenzoyl chloride in a solution of dichloromethane; imidazole and t-butyldiphenylsilyl chloride in a solution of methylene chloride; and the like. For example, as shown in Reaction Scheme C, the C-4",14-dihydroxy-C-3"-methoxy macrolide 1 may be protected as the bistriethylsilyl ether (TES) 1a by treatment with triethylsilyl trifluoromethanesulfonate in methylene chloride. The C-1 hydroxyl group of 1a may be dehydrated (eliminated) to give C.sub.1-2 dehydro derivative 4 by Mitsunobu conditions which require diethyldiazo dicarboxylate (DEAD) and triphenyl phosphine in an aprotic solvent such as tetrahydrofuran at reduced temperatures, preferably 0.degree. C. or below [Mitsunobu, et. al. Tetrahedron, 26, 5731 (1970)].
The C-1, C-2 olefin of compound 4 may be reduced by a variety of methods. In particular, reaction with a reducing reagent such as potassium triphenylborohydride at reduced temperatures, preferably at -78.degree. C. for an extended time period ranging from 24 to 72 hours to give compound 6. The C-14 and C-4" protecting groups of compounds 4 or 6 can be removed with HF-pyridine complex in tetrahydrofuran to give free alcohols 5 and 2. ##STR19##
The C-1 hydroxyl group of keto derivative 2 can be dehydrated to compound 8 utilizing Mitsunobu conditions (DEAD, Ph.sub.3 P, THF) previously described in Reaction Scheme C.
Ketone 9 may be prepared from 7 by procedures described in Reaction Scheme A for the conversion of compound 1 to ketone 2.
Reaction Scheme E
When a derivative of compound I contains a C-14 hydroxyl group (R.sup.3 .dbd.OH, wherein R.sup.1, R.sup.2, R.sup.5, R.sup.10, W and n are as defined above), the hydroxyl group may be eliminated by treatment with p-toluenesulfonic acid, benzenesulfonic acid or methanesulfonic acid in an inert organic solvent such as benzene, or toluene at from 40.degree. C. to 60.degree. C., for about 0.5 to 6 hours, or a sufficient period of time to eliminate the 14-hydroxy group. Neutralization with an aqueous solution of a weak base such as aqueous saturated sodium bicarbonate gives the 14,15-dehydro macrolides. The 14-hydroxy group may also be eliminated by activation followed by basic elimination, as described in U.S. Pat. No. 4,894,366.
By changing the sequence of synthetic steps, all possible variations of substitution may be achieved.
The object compounds of Formula I obtained according to the reactions as explained above can be isolated and purified in a conventional manner, for example, extraction, precipitation, fractional cyrstallization, recrystallization, chromatography, and the like.
It is to be noted that in the aformentioned reactions and the post-treatment of the reaction mixture therein, the stereoisomer(s) of starting and object compounds due to asymmetric carbon atom(s) or double bond(s) of the object compounds of Formula I may occasionally be transformed into the other stereo isomer(s), and such cases are also included within the scope of the present invention.
In the present invention, compounds with asymmetric centers may occur as racemates, as diastereomeric mixtures and as individual diastereomers, with all isomeric forms of the compounds being included in the present invention. These may be prepared by methods such as those disclosed in publications which describe synthetic routes to fragments of the macrolide FR-900506 and the total synthesis of the macrolide FR-900506 itself (J. Am. Chem. Soc. 1989, 111, 1157; J. Am. Chem. Soc. 1990, 112, 2998; J. Org..Chem. 1990, 55, 2786; J. Am. Chem. Soc. 1990, 112, 5583.

The compounds of the present invention are capable of forming salts with various inorganic and organic acids and bases and such salts are also within the scope of this invention. Examples of such acid addition salts (which are negative counterions defined herein as M-) include acetate, adipate, benzoate, benzenesulfonate, bisulfate, butyrate, citrate, camphorate, camphorsulfonate, ethanesulfonate, fumarate, hemisulfate, heptanoate, hexanoate, hydrochloride, hydrobromide, hydroiodide, methanesulfonate, lactate, maleate, methanesulfonate, 2-naphthalenesulfonate, oxalate, pamoate, persulfate, picrate, pivalate, propionate, succinate, tartrate, tosylate, and undecanoate.

The compounds of the invention also have liver regenerating activity and/or activity in stimulating hypertrophy and hyperplasia of hepatocytes. Therefore, they are useful for the treatment and prevention of hepatic diseases such as immunogenic diseases (e.g. chronic autoimmune liver diseases including autoimmune hepatitis, primary biliary cirrhosis and sclerosing cholangitis), partial liver resection, acute liver necrosis (e.g. necrosis caused by toxins, viral hepatitis, shock or anoxia), B-virus hepatitis, non-A/non-B hepatitis and cirrhosis.
The compounds of the invention are also indicated for use as antimicrobial agents, and thus may be used in the treatment of diseases caused by pathogenic microorganisms and the like.
The compounds of Formula I may also be useful in the prevention or treatment of immunodepression (such as AIDS, HIV infection, cancer, senile dementia, trauma (including wound healing, surgery and shock), chronic bacterial infection and certain central nervous system disorders), overdosages or toxicity of such immunosuppressive compounds, and as an adjunct to the administration of an antigen in vaccination.
The pharmaceutical compositions of this invention can be used in the form of a pharmaceutical preparation, for example, in solid, semisolid or liquid form, which contains one or more of the compounds of the present invention, as an active ingredient, in admixture with an organic or inorganic carrier or excipient suitable for external, enteral or parenteral applications. The active ingredient may be compounded, for example, with the usual non- toxic, pharmaceutically acceptable carriers for tablets, pellets, capsules, suppositories, solutions, emulsions, suspensions, and any other form suitable for use. The carriers which can be used are water, glucose, lactose, gum acacia, gelatin, mannitol, starch paste, magnesium trisilicate, talc, corn starch, keratin, colloidal silica, potato starch, urea and other carriers suitable for use in manufacturing preparations, in solid, semisolid, or liquid form, and in addition auxiliary, stabilizing, thickening and coloring agents and perfumes may be used. For example, the compounds of Formula I may be utilized with hydroxypropyl methylcellulose essentially as described in U.S. Pat. No. 4,916,138, issued Apr. 10, 1990, or with a surfactant essentially as described in EPO Publication 0,428,169. Oral dosage forms may be prepared essentially as described by T. Hondo, et al., Transplantation Proceedings, 1987, XIX, Supp. 6, 17-22. Dosage forms for external application may be prepared essentially as described in EPO Publication 0,423,714. The active object compound is included in the pharmaceutical composition in an amount sufficient to produce the desired effect upon the process or condition of diseases.
For the treatment of these conditions and diseases caused by immmunoirregularity a compound of Formula I may be administered orally, topically, parenterally, by inhalation spray or rectally in dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles. The term parenteral as used herein includes subcutaneous injections, intravenous, intramuscular, intrasternal injection or infusion techniques.
For the treatment of reversible obstructive airways disease, it is preferable that the compound of Formula I be administered by inhalation to the lung, especially in the form of a powder.
For modifying the activity and/or toxicity of FK-506-type immunosuppressants, a compound of Formula I may be administered prior to, in conjuction with or subsequent to the administration of an FK-506-type of a compound.
The compounds of Formula I may optionally be employed in co-therapy with anti-proliferative agents. Particularly preferred is co-therapy with an antiproliferative agent selected from the group consisting of azathioprine (AZA), brequinar sodium, deoxyspergualin (DSG), mizaribine, mycophenolic acid morpholino ester (RS-61443), cyclosporin and rapamycin.
The compounds of Formula I may also be employed in conjunction with (or in a pharmaceutical composition additionally comprising):
(1) a 5.alpha.-reductase inhibitor,
(2) a cyclosporin,
(3) a potassium channel opener (such as minoxidil), or
(4) a phospholipid.
Such co-therapy is particularly useful in hair revitalizing, such as in the treatment of male pattern alopecia, female pattern alopecia, alopecia senilis or alopecia areata, by providing epilation prevention, hair germination, and/or a promotion of hair generation and hair growth.
Such co-therapy is further useful in treating the hyperandrogenic conditions of androgenic alopecia, acne vulgaris, seborrhea, and female hirsutism.
For co-therapy of these conditions and diseases a compound of Formula I may be administered in combination with prior to, concurrent to, or subsequent to the administration of other agent(s).
For hair revitalizing the compound of Formula I may be administered topically or orally. Cyclosporin may be administered topically or orally. Although the 5.alpha.-reductase inhibitor or the potassium channel opener may be administered topically or orally, it is preferable that it be administered topically to the scalp. For unitary formulation, however, the preferred mode of administration is topically. It is especially preferred that the hair revitalizing composition of the present invention is administered by a percutaneous administration or by spraying onto the skin.
Dosage levels of the compounds of the present invention are of the order from about 0.005 mg to about 50 mg per kilogram of body weight per day, preferably from about 0.1 mg to about 10 mg per kilogram of body weight per day, are useful in the treatment of the above-indicated conditions (from about 0.7 mg to about 3.5 mg per patient per day, assuming a 70 kg patient). In addition, the compounds of the present invention may be administered on an intermittent basis; i.e. at daily, semiweekly, weekly, semi-monthly or monthly intervals.
The amount of active ingredient that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. For example, a formulation intended for the oral administration of humans may contain from 0.5 mg to 5 gm of active agent compounded with an appropriate and convenient amount of carrier material which may vary from about 5 to about 95 percent of the total composition. Dosage unit forms will generally comprise from about 0.01 mg to about 500 mg, and preferably about 0.5 mg to about 100 mg of active ingredient. For external administration the compound of Formula I may be formulated within the range of, for example, 0.0001% to 60% by weight, preferably from 0.001 to 10% by weight, and most preferably from about 0.005 to 0.8% by weight.
It will be understood, however, that the specific dose level for any particular patient will depend on a variety of factors including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, route of administration, rate of excretion, drug combination and the severity of the particular disease undergoing therapy.
The following examples are given for the purpose of illustrating the present invention and shall not be construed as being limitations on the scope or spirit of the instant invention.

T-Cell Proliferation Assay
1. Sample Preparation
The compounds to be assayed were dissolved in absolute ethanol at 1 mg/ml.
2. Assay
Spleens from C57B1/6 mice were taken under sterile conditions and gently dissociated in ice-cold RPMI 1640 culture medium (GIBC), Grand Island, N.Y.) supplemented with 10% heat-inactivated fetal calf serum (GIBO)). Cells were pelleted by centrifugation at 1500 rpm for 8 minutes. Contaminating red cells were removed by treating the pellet with ammonium chloride lysing buffer (GIBO)) for 2 minutes at 4.degree. C. Cold medium was added and cells were again centrifuged at 1500 rpm for 8 minutes. T lymphocytes were then isolated by separation of the cell suspension on nylon wool columns as follows: Nylon wool columns were prepared by packing approximately 4 grams of washed and dried nylon wool into 20 ml plastic syringes. The columns were sterilized by autoclaving at 25.degree. F. for 30 minutes. Nylon wool columns were wetted with warm (37.degree. C.) culture medium and rinsed with the same medium. Washed spleen cells resuspended in warm medium were slowly applied to the nylon wool. The columns were then incubated in an upright position at 37.degree. C. for 1 hour. Non-adherent T lymphocytes were eluted from the columns with warm culture medium and the cell suspensions were spun as above.
Purified T lymphocytes were resuspended at 2.5.times.10.sup.5 cells/ml in complete culture medium composed of RPMI 1640 medium with 10% heat- inactivated fetal calf serum, 100 mM glutamine, 1 mM sodium pyruvate, 2.times.10.sup.-5 M 2-mercaptoethanol and 50 .mu.g/ml gentamycin. Ionomycin was added at 250 ng/ml and PMA at 10 ng/ml. The cell suspension was immediately distributed into 96 well flat-bottom microculture plates (Costar) at 200 .mu.l/well. The various dilutions of the compound to be tested were then added in triplicate wells at 20 .mu.l/well. The compound 17-allyl-1,14-dihydroxy-12-[2'-(4"-hydroxy-3"-methoxycyclohexyl)-1'-methylvinyl]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-aza-tricyclo[22.3.1.0.sup.4,9 ]octacos-18-ene-2,3,10,16-tetraone was used as a standard. The culture plates were then incubated at 37.degree. C. in a humidified atmosphere of 5% CO.sub.2 -95% air for 44 hours. The proliferation of T lymphocytes was assessed by measurement of tritiated thymidine incorporation. After 44 hours of culturing, the cells were pulse-labelled with 2 .mu.Ci/well of tritiated thymidine (NEN, Cambridge, Mass.). After another 4 hours of incubation, cultures were harvested on glass fiber filters using a multiple sample harvester. Radioactivity of filter discs corresponding to individual wells was measured by standard liquid scintillation counting methods (Betacounter). Mean counts per minute of replicate wells were calculated and the results expressed as concentration of compound required to inhibit tritiated thymidine uptake of T-cells by 50%. A selection of compounds were tested according to the previous procedure and had activity in inhibiting the proliferation of T-cells in the aforementioned assay. The results of this assay are representative of the intrinsic immunosuppressive activity of the compounds of the present invention.
For determining antagonist activity, the foregoing procedure is modified in that dilutions of compounds are cultured with 17-ally-1,14-dihydroxy-12-[2'-(4"-hydroxy-3"-methoxycyclohexyl)-1'-methylvinyl]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo[22.3.1.0.sup.4,9 ]octacos-18-ene-2,3,10,16-tetraone (as a standard) at a concentration of 1.2 nM, a concentration which inhibits T cell proliferation by 100%, the concentration of compound required to reverse the inhibition obtained by the standard alone by 50% is measured, and the ED.sub.50 value is determined.
