All alkenyl groups described above and below can include ethenyl, propenyl and butenyl groups in either the E or Z configuration, for example.

Suitable heteroaryl groups have 1-2 rings, each ring having 1-3 heteroatoms, e.g., O, N or S; typically the total number of heteroatoms in the heterocycle being 1-2. Typical examples include, inter alia, 2-, 3-, and 4-pyridine, 2-, 4-, and 5-pyrimidine, pyrazine; 2- and 3-furan, 2- and 3-thiophene, and all isomers of thiazole, imidazole and indole.

The cycloalkyl and cycloalkenyl groups contained in R.sup.2 may contain 4-7 carbon atoms, preferably 5 to 6 carbon atoms, e.g., cyclopentyl, cyclohexyl, cyclopentenyl, and cyclohexenyl.

The alkyl, alkoxy as well as acyloxy groups contained in R.sup.5 and R.sup.6 and, respectively, R.sup.7, R.sup.8, R.sup.9, R.sup.10 and U of general Formula I are to contain in each case 1-4 carbon atoms, the methyl, ethyl, propyl, isopropyl, methoxy, ethoxy, propoxy, isopropoxy, formyl, acetyl, and propionyl groups being preferred.

Among the alkenyl residues in R.sup.6, the propenyl and butenyl groups are preferred; these can be present in the E or Z configuration. In other words, if R.sup.6 stands for --CH.dbd.CH--(CH.sub.2).sub.k --CH.sub.2 --R.sup.9 then k is to mean preferably 0 or 1.

The novel compounds of general Formula I are prepared according to this invention by the process described below.

The starting compounds of Formula II ##STR6## wherein

R.sup.1a and R.sup.2a have the same meanings as R.sup.1 and R.sup.2, respectively, in general Formula I and wherein optionally hydroxy, mercapto, amino, oxo and/or terminal acetylene groups present in R.sup.2a are blocked,

n means the number 1 or 2,

K is a keto group blocked in the form of the ketal or thioketal, and

W is a bromine or iodine atom,

are produced, starting with the epoxides of general Formula IV obtained according to the directions in, for example, European Patent Application Publication Number 0 110 434, DE 34 38 484 or European Patent Application Publication Number 0 127 864 ##STR7## wherein R.sup.1c, K.sup.b and n.sup.b have the same meanings as R.sup.1, K and n, by nucleophilic addition of a suitable thiophenolate to the number 10 carbon atom.

Various synthesis routes can be chosen, in this connection, depending on the substituents R.sup.2a desired in the intermediate products.

If the thiophenolate residue to be introduced is to carry, in the m-position with respect to the sulfur atom, an amino grouping (R.sup.3, R.sup.4 =CH.sub.3, C.sub.2 H.sub.5, as well as the corresponding monoalkyl compounds), then it is possible first to add 3-mercaptoaniline in nucleophilic fashion to the carbon atom number 10 of the steroid skeleton with the aid of a strong base, e.g. n-butyllithium, and subsequently to produce the corresponding N-monoalkyl compound by one-time acylation of the amino group and subsequent reduction of the N-monoacyl compound, or to prepare the corresponding N-dialkylamino compound by twice acylating in sucession and by reduction. Preferably, the mixed anhydride of formic acid and acetic acid is utilized as the acylating agent, and after reduction the corresponding monomethyland, respectively, dimethylamino compound is accordingly obtained. Other amino compounds according to the claims can be produced analogously.

During the acylation of the amino group, the 17-hydroxy group is in each case likewise acylated, but is then liberated again during reduction and/or during the working up of the reaction product. A preferred reducing agent utilized is a complex hydride, especially lithium aluminum hydride.

Another possibility for opening the epoxide IV resides in adding a thiophenolate of the formula ##STR8## to the epoxide IV in a nucleophilic fashion.

In both instances, a halogen atom (bromine or iodine) is then introduced in the o'-position of the phenyl ring by halogenation, preferably by bromination with N-bromosuccinimide. The reaction sequence set forth as the first hereinabove is demonstrated in Examples 3A to 3F for preparing 10.beta.-(2-bromo-5-diethylaminophenylthio)-3,3-(2,2-dimethyltrimethylenedioxy)estr-9(11)-ene-5.alpha.,17.beta.-diol.

In a further version of the process of this invention, the epoxide of Formula IV is reacted directly with a 2-bromo- or 2-iodothiophenolate already carrying in the 5-position the substituent R.sup.2a desired in the intermediate product of Formula II, or a precursor thereof, for example with 2-bromo-5-methoxysodium thiophenolate.

Optionally after blockage of the functional group present on the phenyl ring, the novel intermediates of Formula II are subjected to cyclizing with the formation of the 10.beta.,11.beta.-bridged structure.

The hydroxy, mercapto and keto blocking groups encompassed by R.sup.2a and K in Formula II are groups readily cleavable in an acidic medium, such as, for example, the methoxymethyl, ethoxymethyl, tetrahydropyranyl, ethylenedioxyketal, ethylenedithioketal or 2,2-dimethyltrimethylenedioxyketal group.

Blocking groups for amino and terminal acetylene groups, e.g. the trimethylsilyl and tert-butyldimethylsilyl groups, are likewise known to one skilled in the art and are split in accordance with the desired reaction sequence also by following methods known in the literature [Synthesis 1980, 627; J. Org. Chem. 46 (1986): 2280].

Cyclization of the intermediate products II to the novel 10.beta.,11.beta.-bridged steroids of general Formula IIIa ##STR9## wherein R.sup.1b, R.sup.2b, K.sup.a and n.sup.a have the same meanings as R.sup.1, R.sup.2, K and n, respectively, but wherein optionally a hydroxy, mercapto, amino, oxo or terminal acetylene group present in is blocked, which are likewise the subject matter of this invention, takes place by reductive radical cyclization in an inert solvent. An advantageous reducing agent in this process is, according to this invention, a trialkyltin hybride, especially tributyltin hydride, with the addition of a radical-forming agent, e.g. azobisisobutyronitrile. Toluene is an example of a suitable solvent. Cyclization is performed under reflux and, for enhancing the radical reaction, under irradiation with a light source (For example, a 300-watt bulb with tungsten filament).

Conversion of the thus-obtained cyclization products into the finally desired end products of Formula I takes place in accordance with methods know per se, in that

(a) the C-17 hydroxy group is optionally oxidized and subsequently

(b) if desired, a hydroxy group on the phenylene ring carrying a blocking group is freed of this blocking group, a corresponding perfluoroalkyl sulfonate is produced, if desired, from the hydroxy compound, optionally the perfluoroalkyl sulfonate is converted, with a correspondingly substituted trialkyltin compound, into a compound which, optionally after further reactions, carries on the phenylene ring the desired substitution pattern,

or first (b) is performed, and then (a) is carried out, and thereafter, if desired,

(c) the D ring is functionalized in the desired way according to conventional methods, the thus-obtained product is subjected, with formation of the 4(5)-double bond, to the effect of a dehydrating agent which is also capable of liberating the 3-oxo group and optionally further blocked groups, or

(d) the thus-obtained product is subjected, with the formation of the 4(5)-double bond, to the effect of a dehydrating agent also capable of liberating the 3-oxo group and optionally further blocked groups, and subsequently, after blockage of the 3-oxo group, the D ring is functionalized in the desired way,

or the steps (a) and (b) or (b) and (a) are executed after step (c) or (d), the thus-obtained product is optionally freed of blocking groups, the hydroxy, mercapto and/or amino group that may be present on the phenylene ring is, if desired, alkylated or acylated, if desired a cyanide residue is introduced into the phenylene ring, optionally is reacted with hydroxylamine hydrochloride to the product of Formula I wherein X means the hydroxyimino grouping N.about.OH, or a pharmaceutically compatible acid addition salt thereof is produced.

During the course of these reaction routes it may be necessary to intermediarily reintroduce blocking groups into intermediates, for example for functional groups contained in Z, or for the 3-keto group during the subsequent construction of the D ring.

The oxidation of the 17.beta.-hydroxy group, required for the preparation of almost all final products, is conventionally performed, for example by Oppenauer oxidation or with chromic acid reagents (Jones reagent or chromic acid--pyridine).

In case the process of this invention is interrupted after the oxidizing step, the 17-oxidation products are obtained, derived from Formula IIIa, which are likewise the subject of the present invention.

Liberation of the 3-keto function with the simultaneous cleavage of water and formation of the 4 5)-double bond takes place by treatment with acid or an acidic ion exchanger. The acid treatment is carried out conventionally by dissolving the corresponding 5.alpha.-hydroxy-3-ketal in a water-miscible solvent, such as aqueous methanol, ethanol or acetone, and treating the solution with catalytic amounts of a mineral or sulfonic acid, such as hydrochloric acid, sulfuric acid, phosphoric acid, perchloric acid, or p-toluenesulfonic acid, or an organic acid, such as acetic acid, until the blocking group of the 3-keto function has been removed and water is split off, if desired. In this procedure, other blocking groups present can likewise be split off concomitantly in part or entirely since the acidic agent utilized for the splitting off step does not (necessarily) have a selective effect; optionally, labile groups must again be blocked after formation of the .DELTA..sup.4 -double bond and before further reaction steps are performed. In this connection, attention is invited, as a representative example, to the reaction step 4D.fwdarw.4E prior to oxidation of the 17.beta.-OH-group in Example 4F. The reaction, proceeding at temperatures of 0.degree. to 100.degree. C., can also be carried out with an acidic ion exchanger. The progression of the reaction can be observed by means of analytical methods, for example by subjecting withdrawn samples to thin-layer chromatography.

In general, the removal of blocking groups and the step of splitting off water is accomplished in one reaction step by allowing the corresponding 5.alpha.-hydroxy-3-ketal (or 5-ene-3-ketal) to react for a certain period of time in a strongly acidic medium. However, it is equally possible according to this invention to perform the removal of blocking groups and the step of splitting off water in two mutually separate reaction stages by first obtaining, by a shorter treatment of the corresponding 5.alpha.-hydroxy-3-ketal in a moderately acidic medium, initially the corresponding 5.alpha.-hydroxy-3-keto compound and optionally isolating same. The 5.alpha.-hydroxy-3-keto compound is then converted into the 3-keto-4-ene compound by further treatment with an acid while water is being split off.

Upon further study of the specification and appended claims, further objects and advantages of this invention will become apparent to those skilled in the art.

A quite special advantage of the present invention resides in the large bandwidth of the substituents that can be introduced at the o-phenylene ring. On the one hand, the substituent R.sup.2, present in the subsequent final product, can be present already in the intermediate of Formula II by having been introduced directly with the thiophenolate via the nucleophilic addition to the epoxide of Formula IV, or by having been subsequently added at the 5-position of the added thiophenolate residue. The number of compounds producible in this way, substituted on the o-phenylene ring in the final product, is relatively limited since not all of the substituents desirable in the end product will withstand, without damage, the conditions of nucleophilic addition of the thiophenolate to the respective 5.alpha.,10.alpha.-epoxide IV and, in particular, the reductive conditions during cyclization of the intermediate product II into a 10.beta.,11.beta.-bridged steroid of Formula III ##STR10##

Thus, a further aspect of this invention is to provide intermediate components of Formula III, wherein R.sup.1b, R.sup.2b, K.sup.a, and n.sup.a have the same meanings as R.sup.1, R.sup.2, K and n of Formula I, respectively, but wherein optionally a hydroxy, mercapto, amino, oxo, and/or terminal acetylene group present in R.sup.2b is blocked, and Q is R.sup.5 and T is R.sup.6 and have the same meanings as R.sup.5 and R.sup.6 of Formula I, or Q and T jointly are a keto oxygen atom.

On the other hand, another embodiment of the process of this invention makes it possible to vary the substituent in the o-phenylene ring over a wide range by introducing the substituent only after cyclization, namely before or after completion of the structure of the A and D rings. For this purpose, the hydroxy group present and blocked in the o-phenylene ring is freed of its blocking group, and the corresponding perfluoroalkyl sulfonate compound is produced from the free OH compound by reaction with perfluoroalkyl sulfonic acid anhydride (alkyl=C.sub.1 -C.sub.4) by using conventional methods [P. J. Stang, M. Hanack and L. R. Subramanian, Synthesis 85 (1982)].

This perfluoroalkyl sulfonate compound is then converted, by reaction with a correspondingly substituted trialkyltin compound, into a compound which, in this case, either a ready exhibits the desired substitution pattern on the phenylene ring or has this pattern imparted to it by additional reaction(s) performed on the substituent introduced via the trialkyltin compounds. The thus-occurring displacement of the perfluoroalkyl sulfonate residue and the introduction of the new substituent from the substituted trialkyltin compound is preferably conducted with catalysis by a transition metal. In this connection, palladium (0) compounds have proven to be especially effective, e.g. tetrakis(triphenylphosphine) palladium (0) (J. E. McMurry and S. Mohanraj, Tetrahedron Letters, 24:2723-2726, No. 27, 1983; X. Lu and J. Zhu, Communications, pp. 726-727, 1987; Q. -Y. Chen and Z. -Y. Yang, Tetrahedron Letters 27:1171-1174, No. 10, 1986; S. Cacchi, P. G. Ciattini, E. Morera and G. Ortar, Tetrahedron Letters 27:3931-3934, No. 33, 1986; A. M. Echavarren and J. K. Stille, J. Am. Chem. Soc. 109:5478-5486, 1987).

Example 4 represents a reaction sequence wherein first of all the corresponding (1-ethoxyvinyl) compound is prepared from the trifluoromethanesulfonate compound by reaction with (1-ethoxyvinyl)tributyltin with the addition of tetrakis(triphenylphosphine) palladium (0), and this product is subsequently converted into the corresponding acetyl compound by acidic cleavage and rearrangement. After renewed blockage of the thus-liberated 3-keto function and of the newly formed keto function in the acetyl substituent in the 5-position of the o-phenylenethio residue, the 17.beta.-OH group can be oxidized and added to the thus-formed keto group in nucleophilic fashion.

However, the process of this invention also makes it possible to introduce the substituent desired at the phenylene ring directly, for example the vinyl substituent by reacting the trifluoromethanesulfonate compound with (vinyl)tributyltin.

Additional examples for reactions possible at the trifluoromethanesulfonate group can be found in the European Patent Application EP-A Publication Number 0283428 (corresponding to PCT/DE 88/00150) and, above all, in the aforementioned publications.

Educts having a D-homo steroid skeleton can be obtained, for example, by Tiffeneau rearrangement analogously to the directions published in Australian J. Chem. 8:519 (1955) and in "Organic Reactions in Steroid Chemistry" vol. 2:388 (1972). The required 17.alpha.-amino-methyl-17.beta.-hydroxy compounds are produced, for example, via opening of the 17,20-spiroepoxides with ammonia or also by lithium aluminum reduction of the acetylated 17.beta.-hydroxy-17.alpha.-cyano compounds. The spiroepoxides are obtainable by reacting the corresponding 17-ketones with dimethylsulfonium methylide in dimethylformamide [Journal f. prakt. Chemie 314:667-668 (1972)]. The acetylated cyanohydrins can be produced by chemical addition of hydrogen cyanide to the corresponding 17-ketones and subsequent acetylation according to known protocols [e.g. Australian J. Chem. 8:519 (1955)].

Educts having an unsaturated D ring can be obtained, for example, by modified Saegusa oxidation [Tetrahedron 42:2971 (1986)] of the corresponding enol compounds of the 17-ketone. For example, the trimethylsilyl enol ether can be prepared by converting the 17-ketone with lithium diisopropylamide in tetrahydrofuran into the corresponding enolate and scavenging by trimethylchlorosilane (Synthesis 1983:1).

Introduction of the substituents R.sup.5 and R.sup.6 takes place according to the customary methods of C-17 side chain construction by nucleophilic addition to the 17-ketone obtained, for example, by Oppenauer oxidation of the C-17 hydroxy group and secondary reactions ("Terpenoids and Steroids", Specialist Periodical Report, The Chemical Society, London, vol. 1-12.

Introduction of the substituent --C.tbd.C--U as R.sup.6 wherein U has the above-indicated meanings takes place with the aid of a compound of the general formula MC.tbd.C--U' wherein U' is the residue U blocked with a blocking group, e.g. trimethylsilyl or tert-butyldimethylsilyl or wherein, if U is an alkyl group of 1-4 carbon atoms, U' proper represents the residue U.

The organometallic compound can also be formed in situ and made to react with the 17-ketone. Thus, it is possible, for example, to treat the 17-ketone in a suitable solvent with acetylene and an alkali metal, especially potassium, sodium or lithium, in the presence of an alcohol or in the presence of ammonia. The alkali metal can also be used in the treatment in the form of, for example, methyllithium or butyllithium. Especially suitable solvents are dialkyl ethers, tetrahydrofuran, dioxane, benzene and toluene.

The introduction of 3-hydroxypropyne, -propene and, respectively, -propane in the 17-position takes place by reacting the 17-ketone with the dianion of the propargyl alcohol (3-hydroxypropyne), for example with the dipotassium salt of propargyl alcohol formed in situ, to the 17.alpha.-(3-hydroxyprop-1-ynyl)-17.beta.-hydroxy derivative or with metalated derivatives of 3-hydroxy-propyne, e.g. with 1-lithium-3-(tetrahydropyran--2'-yloxy)prop-1-yn-1-ide, to the 17.alpha.-[3-(tetrahydropyran-2'-yloxy)prop-1-ynyl -17.beta.-hydroxy derivative which can then be hydrogenated to the 17-(3-hydroxypropyl- or -hydroxypropenyl)-17.beta.-hydroxy compounds. This is accomplished, for example, by hydrogenation at room temperature and under normal pressure in solvents such as methanol, ethanol, propanol, tetrahydrofuran (THF) or ethyl acetate with the addition of noble metal catalysts such as platinum or palladium.

The introduction of homologous hydroxyalkyne, hydroxyalkene and hydroxyalkane groups takes place correspondingly with homologs of propargyl alcohol.

The compound with the Z-configured double bond in the hydroxypropenyl group is formed by hydrogenation of the acetylenic triple bond with a deactivated noble metal catalyst (J. Fried, J. A. Edwards: Organic Reactions in Steroid Chemistry, Van Nostrand Reinhold Company 1972, p. 134; and H. O. House: Modern Synthetic Reactions 1972, p. 19). Examples of suitable deactivated noble metal catalysts are 10% palladium on barium sulfate in the presence of an amine or 5% palladium on calcium carbonate with the addition of lead(II) acetate. The hydrogenation is interrupted after absorption of one equivalent of hydrogen.

The compound having the E-configured double bond in the hydroxypropenyl group is produced by reduction of the acetylenic triple bond in a manner known per se. Quite a number of methods for converting alkynes into trans-olefins have been described in the literature, for example the reduction with sodium in liquid ammonia [J. Am. Chem. Soc. 63:216 (1941)], with sodium amide in liquid ammonia [J. Chem. Soc. (1955), 3558], with lithium in low-molecular amines [J. A. Chem. Soc. 77:3378 (1955)], with boranes [J. Am. Chem. Soc. 93:3395 (1971) and 94:6560 (1972)], with diisobutyl aluminum hydride and methyllithium [J. Am. Chem. Soc. 89:4245 (1967)}. Another possibility resides in reducing the triple bond with chromium(II) sulfate in the presence of water or dimethylformamide in a weakly acidic medium J. Am. Chem. Soc. 86:4358 (1964)] as well as, in general, reduction under the effect of transition metal compounds with a change in the oxidation stage.

Introduction of the hydroxyalkenes can also be brought about directly by addition of a corresponding metalated hydroxyalkenyl compound, such as, for example, 1-lithium-3-(tetrahydropyran-2'-yloxy)prop-1(E)-ene (J. Org. Chem. 40:2265, (1975)) or 1-lithium-3-(tetrahydropyran-2'-yloxy)prop-1(Z)-ene (Synthesis 1981:999). Homologs can likewise be introduced in this way.

The introduction of 3-hydroxypropane in the 17-position can also take place directly by reacting the 17-ketone with metalated derivatives of 3-halopropanols --wherein the hydroxy group is present in the metalating step as an alcoholate (Tetrahedron Letters 1978:3013) or as a blocked function (J. Org. Chem. 37:1947,(1972))--to obtain the 17-(3-hydroxypropyl)-17.beta.-hydroxy compound or, respectively, the compound blocked at the terminal hydroxy group. Examples of suitable blocking groups are the ethoxyethyl, tetrahydropyranyl and methoxymethyl groups.

If final products of Formula I are desired wherein R.sup.5 /R.sup.6 mean ##STR11## then the 17-(3-hydroxypropyl) compound is oxidized in a manner known per se, for example with Jones reagent, pyrolusite, pyridinium dichromate, pyridinium chlorochromate, chromic acid--pyridine or the Fetizon reagent silver carbonate/"Celite" [Compt. rend. 267:900 (1968)].

Final products of Formula I wherein R.sup.5 /R.sup.6 mean ##STR12## are produced by ring closure reaction of the corresponding 17-(3-hydroxyprop-1 Z)-enyl)-17.beta.-hydroxy educt.

The 17-cyanomethyl side chain is built up conventionally from the 17-ketone, for example via the 17-spiroepoxide and cleavage of the spiroepoxide with HCN according to Z. Chem. 18:259-260 (1978).

Also the introduction of the 17-hydroxyacetyl side chain takes place according to known methods, for example according to the methods disclosed in J. Org. Chem. 47:2993-2995 (1982), Chem. Ber. 113:1184 (1984), and, respectively, U.S. Pat. No. 4,600,538.

In order to introduce the groupings ##STR13## the 17-ketone is converted, with tosylmethylisocyanide (Chem. Ind. 1972:213), into the 17-nitrile compound Tetrahedron 31:2151 (1975)] which latter can be converted directly into the 17-acetyl compound with methyllithium or methylmagnesium bromide; the 17-acetyl compound yields, after enolizing with potassium tert-butylate in tetrahydrofuran and reaction with methyl iodide, the desired 17.alpha.-methyl-17.beta.-acyl grouping. This sequence of methyl addition to the nitrile and subsequent alkylation can also be executed in reverse order.

Free hydroxy or mercapto and/or amino groups present in Z and, respectively, on the phenylene ring can be conventionally alkylated or acylated.

Besides the already described method, it is possible to convert compounds having a dialkylamine substituent on the phenylene ring in good yields into the corresponding (N-cyano-N-alkylaminoaryl) derivatives by reaction with cyanogen bromide in aprotic solvents, such as, for example, dioxane, benzene or toluene at an elevated temperature (amine degradation according to Braun) in analogy to the directions set forth, for example, in Org. Reactions 7:198 (1953), K. W. Bentley, Techniques of Organic Chemistry 11:773 (1963), and Houben-Weyl, 5/4:151 (1960).

The resultant compounds of Formula I wherein X means an oxygen atom can be converted, if desired, into the oximes (Formula I where X means the hydroxyimino grouping N O wherein the hydroxy group can be syn- or anti-positioned) by reaction with hydroxylamine hydrochloride in the presence of tertiary amines at temperatures of between -20.degree. and +40.degree. C. Suitable tertiary bases are, for example, trimethylamine, triethylamine, pyridine, N,N-dimethylaminopyridine, 1,5-diazabicyclo[4.3.0]nonene-5 (DBN) and 1,5-diazabicyclo[5.4.0]undecene-5 (DBU), pyridine being preferred.

Various methods for introducing and removing a variety of blocking groups where required can be found in Protective Groups in Organic Synthesis, Theodore W. Green, ed., John Wiley, N.Y. (1981), as well as methods which can be found in "Terpenoids and Steroids," supra.

The novel compounds of Formula I, as well as their pharmaceutically compatible addition salts with acids, have valuable pharmaceutical properties. Thus, they exhibit strong affinity to the gestagen receptor and display a surprisingly large range of antigestagen and antiglucocorticoid properties. These important bioactivities can be exploited, e.g., in the field of human and veterinary medicine.

In view of the antigestagenic activity of the active agents, they are suitable for inducing abortion, since they displace progesterone required to sustain pregnancy, from the receptor. For this reason, they are valuable and of interest with a view toward their use for postcoital fertility control. Antigestagenic activity can be routinely determined in each case by use of a conventional pharmacological protocol which measures the ability of a compound to interact with gestagen receptors. Such protocols are described in Fertility and Sterility 40, 253 (1982), Steroids 37, 361 (1981), and U.S. Pat. No. 4,519,946.

They can also be used to treat hormonal irregularities, for inducing menstruation, and for inducing labor.

Furthermore, they can be utilized for the treatment of hormone-dependent carcinomas.

The compounds of Formula I according to this invention, as well as their pharmaceutically compatible acid addition salts, also show antiglucocorticoid activity and, thus, can likewise be used as medicinal agents for the therapy of corticoid-induced disturbances (e.g., glaucoma), as well as for combatting side effects occurring upon long-term treatment with glucocorticoids (e.g., Cushing's syndrome). Therefore, they also are useful in the treatment of disorders which are due to supersecretion of the glucocorticoids; for example, adipositas, arteriosclerosis, hypertension, osteoporosis, and diabetes, as well as insomnia. Antiglucocorticoid activity can be routinely determined in each case by use of a conventional pharmacological protocol. Such protocols are described in U.S. Pat. No. 4,519,946 and G.B. 2,118,186.

Consequently, the invention also concerns medicinal agents based on the pharmaceutically acceptable compounds of Formula I, i.e., compounds that are not toxic in the dosages utilized, as well as the pharmaceutically compatible acid addition salts thereof, optionally together with the usual auxiliary agents and excipients, for administration to patients, e.g., mammals, including humans.

The compounds of this invention and their salts can be processed according to conventional methods of galenic pharmacy into pharmaceutical preparations for enteral, percutaneous, parenteral, or local administration. They can be administered in the form of tablets, dragees, gelcaps, granules, suppositories, implants, syrups, injectable sterile aqueous or oily solutions, suspensions or emulsions, ointments, creams, and gels. Ampoules are convenient unit dosages.

The active ingredient or ingredients can be mixed with the auxiliary compounds customary in galenic pharmacy, e.g., gum arabic, talc, amylose, mannitol, methylcellulose, lactose, tensides such as "Tweens" or "Myrj", magnesium stearate, aqueous or nonaqueous vehicles, paraffin derivatives, and aromatous compounds for flavor amelioration (for example, ethereal oils).

Sustained or directed release compositions can be formulated, e.g., liposomes or those wherein the active compound is protected with differentially degradable coatings. e.g., by microencapsulation, multiple coatings, etc. It is also possible to freeze-dry the new compounds and use the lyophilizates obtained, for example, for the preparation of products for injection.

For topical application, they are employed as non-sprayable forms, viscous to semi-solid, or solid forms comprising a carrier compatible with topical application and having a dynamic viscosity preferably greater than water. Suitable formulations include but are not limited to solutions, suspensions, emulsions, creams, ointments, powders, liniments, salves, aerosols, etc., which are, if desired, sterilized or mixed with auxiliary agents, e.g., preservatives, stabilizers, wetting agents, buffers, or salts for influencing osmotic pressure, etc. For topical application, also suitable are sprayable aerosol preparations wherein the active ingredient, preferably in combination with a solid or liquid inert carrier material, is packaged in a squeeze bottle or in admixture with a pressurized volatile, normally gaseous propellant, e.g., a freon.

Therefore, the invention also relates to pharmaceutical compositions containing as the active ingredient at least one compound of this invention or one of its pharmaceutically compatible acid addition salts.

The hydrochlorides and the methanesulfonates can be cited, in particular, as additional salts of the products of this invention with acids.

Generally, the compounds of this invention are dispensed in unit dosage form comprising 1 to 100 mg in a pharmaceutically acceptable carrier per unit dosage. They are incorporated in topical formulations in concentrations of about 2 to 40 weight percent; for example, from 1 .mu.g of active ingredient in a 50 .mu.g formulation to up to 100 .mu.g of active ingredient in a total of 250 .mu.g.

The preferred dosage ranges for the compounds of this invention when used for the above-described activities are as follows:

a) Antigestagenic activity: 1-1000 mg/day, preferably 20-200, analogously to the known agent RU 38,486 b) Antiglucocorticoid activity: 10-1000 mg/day, preferably 50-1000, analogously to the known agent RU 38,486.

It will be appreciated that the actual preferred amounts of active compound in a specific case will vary according to the specific compound being utilized, the particular compositions formulated, the mode of application, and the particular situs and organism being treated. Dosages for a given host can be determined using conventional considerations, e.g., by customary comparison of the differential activities of the subject compounds and of a known agent, e.g., by means of an appropriate, conventional pharmacological protocol.

As a representative for all compounds of this invention, the abortive effect of the compound of Example 6C was determined for characterizing the antigestagen activity:

The experiments were conducted on female rats weighing about 200 g. After mating had taken place, the beginning of pregnancy was confirmed by detecting sperm in vaginal smears. The day of sperm detection is considered day 1 of gravidity (=d1 p.c.; p.c.=post-coitus).

The animals were treated with the compound to be tested or, respectively, the solvent, after nidation of the blastocysts, from d5 p.c. to d7 p.c. On d9 p.c., the animals were sacrificed and the uteri examined for implants and absorption sites. Photos were made of all uteri. The lack of implants, pathological, hemorrhagic, or otherwise abnormal nidation sites was evaluated as abortion.

The test compound was dissolved in a benzyl benzoate-castor oil mixture (proportion 1+4). The vehicle volume per single dose was 0.2 ml. Treatment was effected subcutaneously.

With a dosage of 3.0 mg/animal/day, this compound was fully effective abortively (n abortion/n test animals treated 4/4; solvent control 0/4).
