Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to the field of steroids, and in particular, to 17α-(substituted-methyl) steroids represented by partial formula (II), wherein Z is selected from residues represented by partial formulas (III) and (IV), which structures possess a variety of valuable biological properties including glucocorticoid and anti-glucocorticoid, progestational and anti-progestational activities. The invention is also directed to pharmaceutical compositions containing the steroids disclosed in this invention. 
     2. Description of the Background Art 
     M. Hubner, K. Ponsold, M. Oettel and R. Freund, [Arzneim.-Forsch, Drug Res. 30:401-406 (1980)] described the preparation of 17β-hydroxy-17α-(substituted-methyl) derivatives of estra-4,9-dien- 3-one (I; R=H, R 1  =Me) and gona-4,9-dien-3-one (I; R=Me, R 1  =Et) in which the substituents were: 
     R 1  =Me; X=N 3 , CN, Br, Cl 
     R 1  =Et; X=N 3 . 
     These structures were characterized as progestational agents. In particular, when R=H, R 1  =Me and X=CN, the steroid designated STS 557 was obtained which had ten times the oral potency of levonorgestrel as a gestagen (M. Hubner and K. Ponsold, Exper. Clin. Endocrinol. 81:109-114 [1983]). Incubation of STS 557 with female rat liver microsomes led to isolaion, inter alia, of the metabolite 17α-cyanomethyl-11β,17β-dihydroxyestra-4,9-dien-3-one (II; R=H, R 1  =Me, R 2  =α-H,β-OH, Z=III, R 3  =H) but no biological activity was reported for this product (Exper. Clin. Endocrinol. 81: 168-174 [1983]). This product is excluded from the claims of this invention. 
     In Eur. Pat. Appln. E.P.129,499 (1984), G. Neef, G. Sauer, R. Wiechert, S. Beie, D. Henderson and R. Rohde describe steroids of type (V) wherein the substituted-methyl group at C17 is introduced via 17-oxo intermediates. The compounds of that invention are characterized by a 13α-methyl substituent and thus fall outside the present claims which require a 13β substituent. 
     In U.S. Pat. No. 4,447,424 to J. G. Teutsch, D. Philibert and R. Deraedt are disclosed steroids of structure (II) wherein the substituents are as follows:

     and Z=(III); where R 3  =H. These structures are claimed to have anti-glucocorticoid properties. They are excluded from the claims of the present invention. 
     U.S. Pat. No. 3,906,096 to Bucourt et al is directed to steroidal compounds which have anti-androgenic and anti-estrogenic activities. The compounds of Bucourt et al are different from the present compounds in that the former have an alkoxy group at the 11 position. Further, the compounds of Bucourt et al do not include the Δ 4 ,9 series of compounds as in this invention, nor does the reference disclose a 17α substituent containing a hetero atom. 
     U.S. Pat. No. 4,540,686 to Philibert et al discloses compounds having anti-glucocorticoid activity. This reference does not disclose 17α substituents containing a hetero atom such as azidomethyl or methoxymethyl. 
     U.S. Pat. No. 4,547,493 to Teutsch et al is directed to steroidal compounds which have anti-glucocorticoid activity. The Δ 4 ,9 steroids of Teutsch et al require a substituent other than hydrogen at the 2 position of the steroid ring system, and therefore the compounds of the reference fall outside of the scope of the present claims. 
     U.S. Pat. No. 4,233,296 to Teutsch et al is directed to 11β-substituted-Δ 4 ,9 -estradienes having progestomimetic activity. The only 17β substituted methyl substituent is a 2-propynyl group. 
     Although a large group of steroidal compounds with biological activity is known, as evidenced by the above-described disclosures, there remains a need to discover new and more effective steroidal compounds possessing biological activity, particularly glucocorticoid/anti-glucocorticoid or progestational/anti-progestational activity. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is an object of the present invention to provide novel steroidal compounds possessing glucocorticoid activity; 
     It is another object of the present invention to provide novel steroidal compounds having anti-glucocorticoid activity; 
     It is yet another object of the present invention to provide steroidal compounds having progestational activity; 
     It is yet another object of the invention to provide novel steroidal compounds having anti-progestational activity. 
     These and other objects of the invention as will hereinafter become more apparent have been accomplished by providing novel 11β-substituted derivatives of 17α-(substituted-methyl) steroids (II) wherein Z is selected from partial structures (III) and (IV), which compounds possess binding affinities to glucocorticoid and to progestational receptors. By virtue of such binding, these compounds possess biological activities in warm-blooded animals. The biological activities are glucocorticoid, anti-glucocorticoid, progestational or anti-progestational activities. This surprising range of biological activities of the products of the present invention stems from overlap in the structural requirements for binding to glucocorticoid and progesterone receptors, and represents an important feature of the present invention. 
     This invention provides for the first time novel 
     17α-Cyanomethyl- (II; X=CN), 
     17α-Azidomethyl- (II; X=N 3 ), 
     17α-Thiocyanomethyl (II; X=SCN), 
     17α-Methoxymethyl (II; X=OMe), and 
     17α-Phenylmethyl(benzyl) (II; X=Ph) 
     derivatives of (II) wherein Z is selcted from partial structures (III) and (IV). In addition it provides for the first time novel 
     17α-Ethynylmethyl (II; X=CH 2  C.tbd.CH) 
     derivatives of (III) providing the substituent R 2  does not contain N or S in the molecule. Of these, the 17α-cyanomethyl, 17α-azidomethyl and 17α-methoxymethyl derivatives are preferred. Functional equivalents of these 17α substituents, such as phenyl substituted by C 1  -C 3  alkyl, and substituted methoxy (e.g., CF 3  O--) or ethoxy are also within the scope of this invention, provided they retain the desired activity. 
     In its broadest embodiment, the present invention covers the above generalized structures, wherein: 
     R is H, acyl (C 1  -C 10 ), lower alkyl (C 1  -C 3 ); 
     R 1  is methyl or ethyl; 
     R 3  is H or methyl; and 
     R 2  is selected from the group consisting of oxo, 11α-hydrogen, 11β- 
     --OH, except when X=CN and R is H 
     -lower alkyl (C 1  -C 10 ); 
     -lower alkenyl (C 1  -C 10 ), with the understanding that when C=1, the alkenyl group is methylene and is attached directly to position C 11  ; 
     -lower alkynyl (C 1  -C 10 ); 
     --C 6  H 5  and --C 6  H 4 .R 4  ; 
     --(CH 2 )n.R 5  wherein n is 1 to 4;

     -piperidinyl; 
     wherein R 4  is selected from the group consisting of ##STR2## --OCH 2  CH 2  NMe 2  (Et 2 ); -lower alkyl (C 1  -C 3 ); 
     --O-lower alkyl (C 1  -C 3 ); 
     -halogen; 
     --CF 3  ; 
     --C 6  H 5  ; 
     --S-lower alkyl or -phenyl; and 
     R 5  is selected from the group consisting of--NMe 2 ,--NEt 2 , ##STR3## OMe.

     Preparation of Compounds of the Present Invention 
     The compounds of the present invention are readily prepared from appropriate 17-oxo precursors of partial structure (VI) by reaction with methylide reagents such as, for example, trimethyl sulfonium iodide and sodium hydride in a solvent such as dimethylsulfoxide, to yield the oxiranes (VII) (C. E. Cook, R. C. Corley, M. E. Wall, J. Org. Chem. 33:2789 [1968]). The latter are then converted into the substituted methyl derivatives (II) by the method of K. Ponsold, M. Hubner, W. Schade, M. Oettel and R. Freund [Pharmazie 33:792 (1965)]. 
     In preparing compounds of type (II) wherein Z=(IV), enol ethers such as (VIII) may be conveniently employed as starting materials. These compounds react readily with methylide reagents to give the oxiranes (IX) which may be converted into substituted methyl derivatives (X) by conventional methods. Dilute acid hydrolysis of (X) yields the 3-oxo-Δ 4  -ketones of partial structure (IV), which may be converted into Δ 1  -derivatives by standard procedures if so desired. 
     Compounds of type (II), wherein R=H, R 1  =Me, R 2  =α-H,β-OH and Z is represented by partial formula (IV) with a Δ 1  -unsaturated linkage are readily prepared from steroid (XI) which is well known in the art [G. Teutsch, G. Costerousse, R. Deraedt. J. Benzoni, M. Fortin and D. Philibert, Steroids 38:651-665, (1981)]. This intermediate reacts with methylide reagents to give the oxirane of partial structure (VII; R 1  =Me). The latter can then be converted into structures [II; X is as hereinabove defined, R=H, R 1  =Me, R 2  =α-H,β-OH, Z is IV; Δ 1 )] by conventional methods as herein above defined. 
     In preparing compounds of type (II) wherein Z=(III), it is preferred to use the 5α-hydroxy intermediate (XII) as starting material. Compound (XII) reacts readily with methylide reagents to give the oxiranes (XIII) which may be converted into 17α-(substituted-methyl) steroids (XIV) by known methods. Mild acid hydrolysis of intermediate (XIV) results in loss of the ketal protecting group with concomitant dehydration to give structures (II) wherein Z=(III). 
     EXAMPLE 1 
     17α-Cyanomethyl-11β-(4-dimethylaminophenyl)-17β-hydroxy-4,9-estradien-3-one 
     Step A: 3,3-Ethylenedioxy-ξ-trimethylsilyloxy-17ξ-cyano-11β-(4-dimethylaminophenyl)-9-estren-5α-ol 
     To a stirred suspension of magnesium (13.124 gm, 0.54 g atom) in dry tetrahydrofuran (179 ml) was added a small crystal of iodine. A solution of 4-bromo-N,N-dimethylaniline (44.72 g, 0.22 mol) and 1,2-dibromoethane (18.75 ml, 0.12 mol) in dry tetrahydrofuran (179 ml) was added at a rate to maintain reflux. Upon completion of the addition, the reaction mixture was heated at 50°-55° C. for 2.5 h, cooled to room temperature and cuprous bromide-dimethyl sulfide complex (11.54 g, 0.056 mol) was added. After the reaction mixture was stirred for an additional 30 min., more tetrahydrofuran (179 ml) was added. This was followed by addition of 3,3-ethylenedioxy-17ξ-trimethylsilyloxy-17ξ-cyano-9,11-estrene-5ξ,10ξ-epoxide (18.98 g) [J. C. Gasc and L. Nedelec, Tetrahedron Lett., 2005 (1971)] in dry tetrahydrofuran (179 ml). After 2 h, the reaction mixture was poured into a vigorously stirred solution of saturated ammonium chloride (1.8 L). The phases were separated and the aqueous phase was re-extracted with ether. The crude residue (22.17 g) from the dry ether layer was partially purified by elution from silica gel 60 (200-430 mesh) using a gradient of methylene chloride/triethylamine (99.9:0.1) and methylene chloride/acetone/triethylamine (97.4:2.5:-0.1). Rechromatography using the same system gave 3.7 g of the 17β-cyano isomer and 1.78 g of the 17α-cyano isomer. β-cyano isomer:  1  HNMR (CDCl 3 , 60 MHz) δ 0.25 [s, Si(CH 3 ) 3  ], 0.55 (s, 18-CH 3 ), 2.88 [s, N(CH 3 ) 2  ], 3.93 [2,--O--(CH 2 ) 2  --O--], 4.23 (m,11-H), 4.33 (s, 5-OH), 6.51 (d, J=9 Hz, Ar-H ortho to dimethylamino), 6.94 (d, J=9 Hz, Ar-H meta to dimethylamino); IR (CH.sub. 2 Cl 2 ) 1615 (C═C), 2947 (saturated hydrocarbon), 3505 cm -1  (5-OH); mass spectrum (70 eV) m/z (rel intensity) 550.3225 (12), 532 (100), C 32  H 46  O 4  N 2  Si requires an M +   at m/z 550.3226. α-cyano isomer:  1  H NMR (CDCl 3 , 60 MHz) δ 0.23 [s, Si(CH 3 ) 3  ], 0.47 (s, 18-CH 3 ), 2.85 [s, N(CH 3 ) 2  ], 3.90 [s,--O--(CH 2 ) 2  --O--], 4.15 (s, 5-OH), 4.22 (m, 11-H), 6.52 (d, J=9 Hz, Ar-H ortho to dimethylamino), 6.93 (d, J=9 Hz, Ar-H meta to dimethylamino). IR (CH 2  Cl 2 ) 1612 (C═C), 2950 (saturated hydrocarbon), 3510 cm -1  (5-OH); mass spectrum (70 eV) m/z (rel intensity) 550.3225 (8.0), 532 (100.0). 
     Step B: 3,3-Ethylenedioxy-11β-(4-dimethylaminophenyl)-5α-hydroxy-9-estren-17-one 
     The mixture of isomers at C-17 obtained in Step A (12.4 g, 22.55 mmol) was dissolved as completely as possible in methanol (900 ml). Sodium hydroxide (10N, 100 ml) was added and the reaction mixture was stirred for 1 h at room temperature.

     Activity 
     EXAMPLE 8 
     The in vitro activity of the subject compounds was determined by measuring the binding affinities (RBA) of these compounds relative to progesterone for the progesterone receptor in the cytosol obtained from estrogen-primed immature rabbit uterus, by measuring the RBA relative to dexamethasone for the glucocorticoid receptor from thymus of adrenalectomized rats and by measuring the RBA relative to estradiol for the estrogen receptor from immature rat uterus. These assays were carried out by the procedures of J. R. Reel et al., Fertility and Sterility, 31, 552 (1979) (progesterone), G. P. Chrousos et al., Endocrinology, 107, 472 (1980) (glucocorticoid), and S. G. Korenman et al, J. Clin. Endocrinol., 28, 127 (1968) (estrogen). The results are presented in Table 1. RBA values greater than 100 indicate a higher affinity for the receptor than the steroid used as standard. Thus, compounds XVa-XVe have affinity for the progestin receptor with RBA&#39;s about half that of the natural hormone progesterone. In some cases, especially XVc and XVd, this is accompanied by very strong binding to the glucocorticoid receptor (ca. 3 times the RBA of the potent corticosteroid dexamethasone). The compounds do not bind to the estrogen receptor and thus appear devoid of inherent estrogenic activity. 
     The strong binding to the glucocorticoid receptor is in surprising contrast to the findings of H. Hoffmann et al. [Exper. Clin. Endocrinol. 81, 146 (1983)] that the simpler compound Ia did not show any glucocorticoid or antiexudative properties and thus illustrates the surprising range of biological activities encompassed by the present series of compounds compared to the prior art. 
     EXAMPLE 9 
     In vivo Antiprogestational Activity 
     The antiprogestational activity of compound XVa was studied after both intrauterine and oral administration. In each case the compound was tested for its ability to inhibit the endometrial response due to subcutaneous administration of progesterone to estrogen-primed immature female rabbits. The methodology used for the intrauterine test has been described by D. A. McGinty et al [Endocrinology, 24, 829 (1939)]. For oral administration of test compounds the method used was analogous to that of Clauberg [Clauberg, Zentr. Gynakol, 54, 2757 (1930)] as modified by McPhail [J. Physiol. (London) 83, 145 (1935)]. 
     The results of these tests are given in Table 2. They show a clear, dose-related antiprogestational effect. This is again in contrast to the results found by S. Stolzner et al. [Exper. Clin. Endocrinol., 81, 115 (1983)] on the simpler analog I (STS 557) which had strong progestational activity. It shows the striking influence of the 11-substituent on biological activity of the subject compounds.

     The compounds of the present invention may be administered by a variety of methods. Thus, those products of the invention that are active by the oral route may be administered in solutions, suspensions, emulsions, tablets, including sublingual and intrabuccal tablets, soft gelatin capsules, including solutions used in soft gelatin capsules, aqueous or oil suspensions, emulsions, pills, lozenges, troches, tablets, syrups or elixirs and the like. Products of the invention active on parenteral administration may be administered by depot injection, implants including silastic and biodegradable implants, intramuscular and intravenous injections. 
     Compositions may be prepared according to any method known to the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents and preserving agents. Tablets containing the active ingredient in admixture with nontoxic pharmaceutically acceptable excipients which are suitable for manufacture of tablets are acceptable. These excipients may be, for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, such as maize starch, or alginic acid; binding agents, such as starch, gelatin or acacia; and lubricating agents, such as magnesium stearate, stearic acid or talc. Tablets may be uncoated or may be coated by known techniques to delay disintegration and adsorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate alone or with a wax may be employed. 
     Formulations for oral use may also be presented as hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, for example calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, such as peanut oil, liquid paraffin or olive oil. 
     Aqueous suspensions of the invention contain the active materials in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients include a suspending agent, such as sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia, and dispersing or wetting agents such as a naturally occurring phosphatide (e.g., lecithin), a condensation product of an alkylene oxide with a fatty acid (e.g., polyoxyethylene stearate), a condensation product of ethylene oxide with a long chain aliphatic alcohol (e.g., heptadecaethyleneoxycetanol), a condensation product of ethylene oxide with a partial ester derived from a fatty acid and a hexitol (e.g., polyoxyethylene sorbitol mono-oleate), or a condensation product of ethylene oxide with a partial ester derived from fatty acid and a hexitol anhydride (e.g., polyoxyethylene sorbitan mono-oleate). The aqueous suspension may also contain one or more preservatives such as ethyl or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents and one or more sweetening agents, such as sucrose or saccharin. 
     Oil suspensions may be formulated by suspending the active ingredient in a vegetable oil, such as arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin. The oil suspensions may contain a thickening agent, such as beeswax, hard paraffin or cetyl alcohol. Sweetening agents, such as those set forth above, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an antioxidant such as ascorbic acid. 
     Dispersible powders and granules of the invention suitable for preparation of an aqueous suspension by the addition of water provide the active ingredients in admixture with a dispersing or wetting agent, a suspending agent, and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those disclosed above. Additional excipients, for example sweetening, flavoring and coloring agents, may also be present. 
     The pharmaceutical compositions of the invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil, such as olive oil or arachis oil, a mineral oil, such as liquid paraffin, or a mixture of these. Suitable emulsifying agents include naturally-occurring gums, such as gum acacia and gum tragacanth, naturally occurring phosphatides, such as soybean lecithin, esters or partial esters derived from fatty acids and hexitol anhydrides, such as sorbitan mono-oleate, and condensation products of these partial esters with ethylene oxide, such as polyoxyethylene sorbitan mono-oleate. The emulsion may also contain sweetening and flavoring agents. 
     Syrups and elixirs may be formulated with sweetening agents, such as glycerol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative, a flavoring or a coloring agent. 
     The pharmaceutical compositions of the invention may be in the form of a sterile injectable preparation, such as a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents which have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, such as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer&#39;s solution and isotonic sodium chloride solution. In addition, sterile fixed oils may conventionally be employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid may likewise be used in the preparation of injectables. 
     The compounds of this invention may also be administered in the form of suppositories for rectal administraton of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials are cocoa butter and polyethylene glycols. 
     They may also be administered by intranasal, intraocular, intravaginal, and intrarectal routes including suppositories, insufflation, powders and aerosol formulation. 
     Products of the invention which are preferably administered by the topical route, and in particular those of Group I, may be administered as applicator sticks, solutions, suspensions, emulsions, gels, creams, ointments, pastes, jellies, paints, powders, and aerosols. 
     Products falling within Group I are of particular utility as topical glucocorticoids of value in the treatment of inflammatory, allergic and other skin conditions, both alone and in combination with an antibiotic such as neomycin. Products falling within Group II are of particular value in pathological conditions characterized by excess endogenous glucocorticoids such as Cushing&#39;s syndrome, hirsutism and in particular when associated with the adrenogenital syndrome, ocular conditions associated with glucocorticoid excess such as glaucoma, stress symptoms associated with excess glucocorticoid secretion and the like. 
     Products falling within Group III are of particular value as progestational agents, ovulation inhibitors, menses regulators, contraceptive agents, agents for synchronization of fertile periods in cattle, endometriosis, and the like. When used for contraceptive purposes, they may conveniently be admixed with estrogenic agents, such for example as ethynylestradiol or estradiol esters. 
     Products falling within Group IV are characterized by antagonizing the effects of progesterone. As such, they are of particular value in control of hormonal irregularities in the menstrual cycle and for synchronization of fertile periods in cattle. They may also be administered in conjunction with prostaglandins, oxytocics, zoapatanol and the like. 
     The compounds of the invention may be used for control of fertility during the whole of the reproductive cycle. They are of particular value as postcoital contraceptives, for rendering the uterus inimical to implantation, and as &#34;once a month&#34; contraceptive agents. They may also be used in conjuction with prostaglandins, oxytocics and the like. 
     A further important utility for the products of the invention lies in their ability to slow down growth of hormone-dependent cancers. Such cancers include kidney, breast, endometrial, ovarian cancers, and prostate cancer which are characterized by possessing progesterone receptors and may be expected to respond to progestational and/or anti-progestational agents. Other utilities of anti-progestational agents include treatment of fibrocystic disease of the breast. Certain cancers and in particular melanomas may respond favorably to corticoid/anticorticoid therapy. 
     The compounds according to the present invention may be administered to any warm-blooded mammal such as humans, domestic pets, and farm animals. Domestic pets include dogs, cats, etc. Farm animals include cows, horses, pigs, sheep, goats, etc. 
     The amount of active ingredient that may be combined with a carrier material to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. For example, a unit dose of the steroid may preferably contain betweeen 0.0001 grams and 1 gram of the active ingredient. A more preferred unit dose is betwen 0.001 and 0.1 grams. 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 and diet of the individual being treated; the time and route of administration; the rate of excretion; other drugs which have previously been administered; and the severity of the particular disease undergoing therapy, as is well understood by those of skill in the art.
