Description
BACKGROUND OF THE INVENTION
This invention relates to new 11.beta.-phenyl-gonanes, processes for their manufacture and pharmaceutical preparations containing them. 11.beta.-phenyl steriods are already known. Thus, for example 11.beta.-aryl-17.alpha.-propinyl- and ethinyl-4,9(10)estradienes are described in European Patent Application 82400025.1 (U.S. Pat. Nos. 4,386,085 and 4,447,424) and 4,386,085, 11.beta.-phenyl-17.alpha.-(3-hydroxypropyl)4,9(10)-estradienes in European Patent Application 84101721.3 (U.S. Pat. No. 4,536,401) 11.beta.-phenyl-17.alpha.-(3-hydroxpropyl-1-enyl)-4,9(10)-estradienes in European Patent Application 84730147.0 (U.S. Ser. No. 685,088) and 17.beta.-hydroxy-17.alpha.-(3-hydroxypropyl)-respectively 17.alpha.-hydroxy-17.beta.-(3-hydroxypropyl)-13 .alpha.-methyl-4,9-gonanes in European Patent Application 84730062.1 (U.S. Ser. No. 621,308). These compounds have a strong affinity for gestagen receptors without themselves possessing gestagenic activity. They are competitive antagonists of progesterone (antigestagens) and are suitable for inducing abortion since they displace from the receptor the progesterone required to maintain pregnancy. They are therefore valuable and interesting with regard to their use as a postcoital fertility control means. They can also be used to treat hormonal irregularities, to bring on menstruation and induce birth. The compounds set out in European Patent Application 84101721.3 and 84730147.0 also have antimineral-corticoid effects in addition to their antigestagenic properties.
On the other hand, the 11.beta.-aryl-17.alpha.-propinyl- and ethinyl-4,9(10)estradienes first mentioned display antiglucocorticoid activity and can thus be used as pharmaceuticals for therapy of corticoid-induced disorders (glaucoma) and to combat side effects that occur during long-term treatment with glucocorticoids (Cushing's syndrome). They therefore also make it possible to combat disorders due to a supersecretion of glucocorticoids, above all adipositas, arteriosclerosis, osteoporosis, diabetes and insomnia.
However, so far there has been no success in achieving a desirable extent of dissociation between antigestagenic and antiglucocorticoid effects of these compounds (G. Teutsch in "Adrenal Steroid Antagonism", Walter de Gruyter Berlin-New York, 1984, p. 43).
SUMMARY OF THE INVENTION
It is thus an object of this invention to provide compounds useful as medicaments, particularly having the mentioned desirable dissociation of activities.
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.
It has now been discovered that the new compounds of general Formula I surprisingly display not only very good antigestagenic and antiglucocorticoid effects but also a differentiation of the two effects. Thus, the compounds of this invention are of Formula I: ##STR3## where A and B together represent an oxygen atom, a CH.sub.2 group or a second bond between carbon atoms 9 and 10,
X is an oxygen atom or the hydroxyimino group N.about.OH,
R.sub.1 is a straight-chained or branched, saturated or unsaturated hydrocarbon aliphatic group (i.e., alkyl, alkenyl or alkynyl) with up to 8 carbon atoms, each of which contains the grouping ##STR4## wherein X is as defined above, R.sub.2 is methyl or ethyl in .alpha. or .beta. position,
wherein, in the case of R.sub.2 methyl or ethyl in the .alpha.-position:
R.sub.3 /R.sub.4 is ##STR5## and where, in the case of R.sub.2 methyl or ethyl in the .beta.-position: R.sub.3 /R.sub.4 is ##STR6## R.sub.5 is a hydrogen atom or an acyl radical of 1 to 4 carbon atoms, Y is a hydrogen, chlorine, fluorine, iodine or bromine atom, or an alkyl, hydroxyalkyl, alkoxyalkyl or acyloxyalkyl group each of 1 to 4 carbon atoms in each alkyl or acyl group,
R.sub.6 is a hydrogen atom, a hydroxy group, an alkyl, O-alkyl or O-acyl group each of 1 to 4 carbon atoms,
m is 0, 1, 2 or 3,
R.sub.7 is hydroxy or cyano or O-alkyl or O-acyl each of 1 to 4 carbon atoms,
k is 0, 1 or 2,
R.sub.8 is a hydrogen atom or an alkyl or acyl group of 1 to 10 carbon atoms each,
each of R.sub.9, R.sub.10, R.sub.11 and R.sub.12 independently is a hydrogen atom, an hydroxy group, an alkyl, alkoxy, acyloxy group each of 1 to 4 carbon atoms or a halogen atom,
and the substituent of the 11.beta.-phenyl radical is in position 3 or 4.
This invention also relates to corresponding pharmaceutical compositions and methods of use.
DETAILED DISCUSSION
The abortive effect was determined to distinguish the antigestagenic effect.
The experiments were performed on rats weighing approximately 200 g. After mating, the beginning of pregnancy was ascertained by demonstrating the presence of sperm in vaginal smears. The day on which the presence of sperm was verified is considered the first day of pregnancy (=dl p.c.). After nidation of the blastocysts from d5 p.c. to d7 p.c., the animals were treated with the respective substance and/or solvent to be tested. On d9 p.c. the animals were killed and the uteri examined for implants and places of resorption. Photographs were made of all the uteri. The absence of implants was evaluated as an abortion.
The test substances were dissolved in a mixture of benzyl benzoate and castor oil (ratio of 1:9). The vehicle volume per individual dose amounted to 0.2 ml. Treatment was subcutaneous (s.c.).
The superiority of the compounds in accordance with the invention will be demonstrated by comparing the biological properties of the compounds in accordance with the invention, the 11.beta.-(4-acetylphenyl)-17.beta.-hydroxy-17.alpha.-(1-propinyl)-4,9-estr adien-3-one (A), 17.beta.-hydroxy-17.alpha.-(3-hydroxy-1(Z)-propenyl)-11.beta.-(4-propionyl -phenyl)-4,9-estradien-3-one (B) and 11.beta.-(4-acetylphenyl)-17.beta.-hydroxy-17.alpha.-(3-hydroxy-1(Z)-prope nyl)-4,9-estradien-3-one (C) with the 11.beta.-(4-dimethylaminophenyl)-17.beta.-hydroxy-17.alpha.-(propin-1-yl)- 4,9)(10)-estradien-3-one RU 38486 described in European Patent 82400025.1 (D), the 11.beta.-(4-dimethylaminophenyl)-17.beta.-hydroxy-17.alpha.- (3-hydroxy-propyl)-4,9(10)-estradien-3-one (E) in EP 84101721.3, the 11.beta.-(4-dimethylaminophenyl)-17.beta.-hydroxy-17.alpha.-(3-hydroxy-pro p-1(Z)-enyl)-4,9(10)-estradien-3-one (F) described in EP 84730147.0 and the 11.beta.-(4-dimethylaminophenyl)-17.beta.-hydroxy-17.alpha.-(3-hydroxyprop yl)-13.alpha. -methyl-4,9-gonadien-3-one (G) as well as the 11.beta.-(4-dimethylaminophenyl-17.alpha.-hydroxy-17.beta.-(3-hydroxypropy l)-13.alpha.-methyl-4,9-gonadien-3-one (H) described in European Patent EP 84730062.1.
From Table 1 it can be seen that only the compounds in accordance with the invention have a fully abortive effect at a dose of 0.3 (A) and 0.1 mg (B,C), i.e., they are more effective than the state-of-the-art compounds by a factor of 3 to 30.
The influence on the tyrosine aminotransferase of the substances in accordance with the invention was ascertained to distinguish the antiglucocorticoid effect. The test system is based on a measurement of the activity of the liver enzyme tyrosine aminotransferase (TAT) in cultures of RHC (rat hepatoma cells). The enzyme catalyzes the first step in the metabolism of tyrosine and can be induced by glucocorticoids in both the liver and hepatoma cells. The activity is easy to measure in crude extracts (Granner and Tomkins, (1970) Meth. Enzymol. 15, 633). The enzyme converts the amino group of tyrosine to 2-oxo-glutaric acid. This results in glutaminic acid and p-hydroxyphenyl pyruvate. In an alkaline solution the more stable p-hydroxybenzaldehyde is formed from the p-hydroxyphenyl pyruvate, the absorption of the former being measured at 331 nm. The TAT activity in RHC cells displays a dose-dependent induction with cortisol (max. activity at 10.sup.-6 M) or dexamethasone (max. activity at 10.sup.-7 M). It is possible to stimulate activity by a factor of 4 to 6 by acting on the basal rate. Simultaneous treatment with corticoid and antiglucocorticoid leads to a decrease in TAT activity.
In this test compound A in accordance with the invention displays 30%, compounds B and C in accordance with the invention less than 1% of the activity of RU 38.486 (D), a substance that can be viewed as standard (7th International Congress of Endocrinology, July 1-7, 1984, Quebec City, Canada; Excerpta Medica, Amsterdam-Oxford-Princeton).
Since compound (A) is 10 times more antigestagenic than (D), and compounds (B) and (C) 30 times more antigestagenic, there is thus a clear dissociation of the antiglucocorticoid and antigestagenic properties.
Another example in accordance with the invention that should be mentioned is 11.beta.-[4-(anti-hydroxyiminomethyl)-phenyl]-17.beta.-hydroxy-17.alpha .-(1-propinyl)-4,9-estradien-3-one-anti-oxime (J); this compound displays an antiglucocorticoid effect similar to that of (D). But in the antigestagen test the effect is at least 10 times weaker than that of (D).
In the gestagen-receptor binding test the affinity of the compounds in accordance with the invention for the gestagen receptor is investigated. The displacement of the agonist by the antagonist is measured in this connection.
Use is made of the cytosol from rabbit-uterus homogenate, which contains the receptor molecule--a protein. This binds progesterone with high affinity and low capacity. If these receptors are loaded with .sup.3 H-progesterone in the presence of the unmarked substance to be tested, the degree to which the .sup.3 H-progesterone is displaced from the receptor depends on the concentration and the binding affinity of the compound to be tested. After separation of the progesterone bound to the receptor from the non-bound progesterone it is possible to obtain the binding in percent and to plot this value against the logarithm of the molar concentration of the substance being tested. Characteristic dose-dependent displacement curves are obtained and it is now possible to ascertain the concentration of the test substance which is required to completely displace the reference substance from the receptor. The competition factor K, the yardstick for the binding power, is defined as the ratio of the concentration of the test substance to the concentration of the reference substance (progesterone), in the case of which both compounds display equally great displacement of .sup.3 H-progesterone from the progesterone-receptor complex, so that a low K-value indicates high binding power (high affinity).
The table shows that compounds A, B, C in accordance with the invention and given as examples, namely 11.beta.-(4-formylphenyl)-17.beta.-hydroxy-17.alpha.-(1-propinyl)-4,9-estr adien-3-one (I) 17.beta.-hydroxy-17.alpha.-(1-propinyl)-11.beta.-(4-propionyl-phenyl)-4,9- estradien-3-one (K), 11.beta.-4(acetylphenyl)-17.beta.-hydroxy-9.alpha., 10.alpha.-methylene-17.alpha.-(1-propinyl)-4-estren-3-one (L) and 3-[11.beta.-(4-acetylphenyl)-17.beta.-hydroxy-3-oxo-4,9-estradien-17.alpha .-yl]-propionic acid lactone (M) are as much as 4 times more effective in the gestagen-receptor binding test than the compound (D) considered standard.
The invention also relates to pharmaceutical preparations containing compounds of general formula I useful, e.g., to treat mammals including humans. The pharmacologically effective compounds of general formula I in accordance with the invention can be processed by the generally known galenical methods into pharmaceutical preparations for enteral, percutaneous or parenteral application.
Conventional excipients are pharmaceutically acceptable organic or inorganic carrier substances suitable for parenteral, enteral or topical application which do not deleteriously react with the active compounds. Suitable pharmaceutically acceptable carriers include but are not limited to water, salt solutions, alcohols, gum arabic, vegetable oils, polyethylene glycols, gelatine, lactose, amylose, magnesium stearate, talc, silicic acid, viscous paraffin, perfume oil, fatty acid monoglycerides and diglycerides, pentaerythritol fatty acid esters, hydroxymethylcellulose, polyvinyl pyrrolidone, etc. The pharmaceutical preparations can be sterilized and if desired mixed with auxiliary agents, e.g., lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, flavoring and/or aromatic substances and the like which do not deleteriously react with the active compounds.
For parenteral application, particularly suitable are injectable sterile solutions, preferably oily or aqueous solutions, as well as suspensions, emulsions, or implants, including suppositories. Ampoules are convenient unit dosages.
For enteral application, particularly suitable are tablets, dragees, suppositories or capsules having talc and/or a carbohydrate carrier or binder or the like, the carrier preferably being lactose and/or corn starch and/or potato starch. A syrup, elixir or the like can be used wherein a sweetened vehicle is employed. Sustained release compositions can be formulated including those wherein the active compound is protected with differentially degradable coatings, e.g., by microencapsulation, multiple coatings, etc.
Generally, the compounds of this invention are dispensed in unit dosage form comprising 10-100 mg in a pharmaceutically acceptable carrier per unit dosage. The dosage of the antigestagenic compounds according to this invention generally is about 1-1,000 mg/day when administered to patients, e.g., humans preferably 5-200 mg/day to the known agent RU 486. The dosage of the compounds of this invention generally is 1-500 mg/day when adminstered to such patients, preferably 1-100 mg/day, to treat, e.g., Cushing Syndrome. Suitable dosage and regimens for a given host can be determined using conventional considerations, e.g., by customary comparison of the differential activities of the subject compound and of a known agent, e.g., by means of an appropriate, conventional pharmacological protocol.
All compounds of this invention will have at least one of the antiglucocordicoidal or antigestagenic activities of this invention. The activity spectrum for a given compound can be routinely determined with no undue experimentation, e.g., using conventional pharmacological protocols, e.g., those described herein. Without intending to limit the scope of this invention in any way, it can be stated that a 17-hydroxypropenyl side chain generally decreases antiglucocordicoidal activity in comparison, e.g., to that of the prior art 17-propinyl side-chain-containing compounds. Further, a 9.alpha., 10.alpha.-CH.sub.2 group generally decreases the antiglucocordicoidal activity. The oxime structure generally lowers the antigestagenic activity.
The alkyl groups contained in R.sub.1 of general formula I may have as many as 8, preferably up to 4, carbon atoms. Suitable alkyl portions in all groups (e.g., alkyl, alkoxy, acyl, acyloxyalkyl, etc.) can be selected from methyl, ethyl, i- or n-propyl, n-, i-, s- or t-butyl, or for R.sub.1 also possibly a pentyl, hexyl, heptyl or octyl group, or for R.sub.8 also possibly a nonyl or decyl group. In the case of the saturated R.sub.1 alkyl radical substitutions, it is preferred that the ##STR7## group is directly connected to the phenyl ring, e.g., preferred are, e.g., the formyl, acetyl, propionyl and butyryl groups or their hydroxyimino derivatives. In the case of the R.sub.1 unsaturated aliphatic radicals, i.e., alkenyl or alkynyl groups of 3-8 C-atoms, .alpha., .beta. unsaturated ##STR8## groupings, in which C-atoms 1 and 2 of the chain carry the double bond, are preferred.
In all alkyl-containing groups, preferred groups are methyl, ethyl, propyl, formyl, acetyl, propionyl, butyryl, methoxy and ethoxy, where appropriate. Preferred acyl groups are alkanoyl groups.
Of the alkenyl radicals, the propenyl group, which can be in the E or Z configuration, is preferred. Thus, when R.sub.4 is --CH.dbd.CH--(CH.sub.2).sub.k --CH.sub.2 --R.sub.6, k preferably is zero. When R.sub.9, R.sub.10, R.sub.11 or R.sub.12 are halogen, chlorine is preferred.
In the case of substituents R.sub.9, R.sub.10, R.sub.11 and R.sub.12, monosubstitution is preferred, i.e., three of these substituents preferably are hydrogen atoms.
The new 13-alkyl-11.beta.-phenyl-gonanes of general formula I are prepared in accordance with this invention by a method comprising in a manner known in the art, exposing a compound of general formula II to a dehydrating agent: ##STR9##
wherein K is a blocked ketone group in the form of a ketal, thioketal, oxime or methyloxime, A, B and R.sub.2 are as defined above, R'.sub.1 is as defined above for R.sub.1 but contains a ##STR10## instead of ##STR11## group, R'.sub.3 has the same meaning as R.sub.3 but any hydroxy groups being conventionally protected, and R'.sub.4 has the same meaning as R.sub.4, but any hydroxy or acyl groups being conventionally protected, and K.sub.l also stands for a hydrogen atom and a protected hydroxy group in addition to the aforementioned meanings of K,
the dehydrating agent also being capable of releasing the protected function(s),
thereby separating water while simultaneously forming the 4(5) double bond,
oxidizing a hydroxy group contained in K.sub.l,
optionally, for the compounds of general formula I thus obtained, with R.sub.9, R.sub.10, R.sub.11 and R.sub.12 in each case being hydrogen atoms, reacting them by microbiological hydroxylation with micro-organisms of the species Streptomyces toyocaensis (DSM 40030) and/or Streptomyces platensis (NRRL 2364) and/or Nigrospora sphaerica (CBS 98469) and/or Neurospora crassa (ATCC 9278),
optionally, for the hydroxylated compounds of the general formula I thus obtained, where at least one of the substituents R.sub.9, R.sub.10, R.sub.11 and R.sub.12 is an hydroxy group, the remaining substituents being hydrogen, epimerizing them at the positions carrying the hydroxy groups, and/or further optionally for these hydroxy groups, etherifying, esterifying or replacing them by a halogen or alkyl radical,
optionally for the hydroxy groups present in R.sub.3 and R.sub.4, esterifying or etherifying them to form a product of general formula I where X is an oxygen atom and, further optionally, subsequently reacting them with hydroxylamine hydrochloride in the presence of tertiary amines at temperatures of between -20.degree. C. and +40.degree. C.
Starting with the compounds of general formula II, these compounds are treated with acid or an acid ion exchanger to split off water while forming the 4(5) double bond and simultaneously remove any protected groups. The acid treatment is performed in the way known in the art inasmuch as the compound of formula II, which contains at least two protected groups, is dissolved in a solvent mixable with water, like aqueous methanol, ethanol or acetone, and the solution is allowed to react with catalytic amounts of mineral or sulfonic acid, like hydrochloric acid, sulfuric acid, phosphoric acid, perchloric acid or p-toluene sulfonic acid, or an organic acid, like acetic acid, until the water has split off and the protected groups removed. The reaction, which takes place at temperatures of 0.degree. to 100.degree. C., can also be undertaken with an acid ion exchanger. The course of the reaction can be followed by analytical methods, for example by thin-layer chromatography of samples.
In an acid medium the protected groups comprised of K, K.sub.1, R'.sub.3 and R'.sub.4 in general formula II are easily splittable groups like, for example, the ethylenedioxyketal, ethylenedithioketal, 2,2-dimethyl-trimethylenedioxyketal, hydroxyimino, methoxyimino, tetrahydropyranyl, methoxymethyl or ethoxymethyl group.
If a compound of general formula II is used, the K.sub.l of which contains a protected hydroxy group, it is subsequently converted into the oxo function by an oxidizing agent customary for the oxidation of allylic hydroxy groups such as, for example, chromic acid, pyridine, pyridinium dichromate, pyridinium chlorochromate, manganese dioxide, silver carbonate on Celite. Conversion with manganese dioxide at temperatures between -20.degree. C. and +40.degree. C. is preferred.
The hydroxy groups are introduced into positions 6, 7, 15 and 16 of the steroid structure of general formula II, with R.sub.9, R.sub.10, R.sub.11 and R.sub.12 in the respective meaning of one hydrogen atom, with the help of microorganisms.
Thus there is a 6.alpha.-hydroxylation if microorganisms of the species Nigrospora sphaerica(CBS 98469) are used for the fermentation. 7.alpha.-hydroxylation is possible with Neurospora crassa (ATCC 9278), 15.beta.with Streptomyces platensis (NRRL 2364) and 16.alpha.-hydroxylation with Streptomyces toyocaensis (DSM 40030).
The fermentations are carried out under the conditions customarily used in the microbiological hydroxylation of steroids with microorganisms. Thus, in customary preliminary experiments the enzyme of the microorganism is analytically examined, especially by thin-layer chromatography, to first ascertain the best fermentation conditions such as, for example, selection of the best nutrient medium, the appropriate substrate solvent or suspension agent, the substrate concentration, technical conditions such as temperature, aeration, pH-value and optimum times for germination, addition of substrate and substrate contact.
It is advisable to apply the substrate in a concentration of approximately 100 to 5000 mg per liter of nutrient medium. The pH-value is preferably set at a range of 5 to 7.5. The growing temperature is from 20.degree. to 40.degree. C., preferably from 25.degree. to 35.degree. C. 0.5 to 5 liters of air per minute per liter of culture are preferably fed in for aeration. It is advisable to follow conversion of the substrate by analysis with thin-layer chromatography. The fermentation takes approximately 30 to 130 hours.
The configuration of these secondary alcohols is reversed by the generally known methods, preferably by way of the Mitsunobu reaction with azodicarbonic acid ester/triphenylphosphine. (Synthesis 1981, 1. Chem. Commun. 1981, 840).
The halogen substituents are introduced into the C-6, C-7, C-15 or C-16 position of the steroid structure in accordance with the methods known in the literature by nucleophilic substitution of the corresponding hydroxy groups together with inversion, preferably with triphenyl phosphine and a halogen source such as, for example CCl.sub.4 or CBr.sub.4 (Chem. Ind. 1966, 900, Can. J. Chem. 1982, 210, J. C. S. Perkin I 1982, 681 Synthesis 1983, 139) or in the case of the fluoride substituent with (diethylamino) sulfur trifluoride (U.S. Pat. No. 3,914,265, J. Org. Chem. 1983, 393).
If introduction of a C-6, C-7, C-15 or C-16 alkyl is desired, use is likewise made of the corresponding hydroxylated educts. After conversion to an appropriate volatile group such as, for example, mesylate, tosylate, iodide, bromide, but preferably tosylate, the hydroxy group is replaced by conversion with lithium dialkylcuprates or organocuprates of the formula alkyl.sub.2 Cu (CN)Li.sub.2 (J. Am. Chem. Soc. 103, 7672 (1981)).
If desired the compounds of general formula I, with X in the meaning of an oxygen atom, can be converted by reaction with hydroxylamine hydrochloride in the presence of tertiary amines at temperatures between -20.degree. and +40.degree. C. into oximes (formula I, with X in the meaning of the hydroxyimino grouping N.about.OH, it being possible for the hydroxy group to be in the syn or anti position). Suitable teriary 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.
If esterificaticn of the compounds of general formula I is desired, in which R.sub.3, R.sub.4, R.sub.9, R.sub.10, R.sub.11 and R.sub.12 contain a hydroxy group, the acylation is done in the manner known in the art, for example, by converting with acid anhydride in pyridine at room temperature.
The manufacture of the initial compounds of general formula II starts, as described for example in European Patent Applications 84101721.3 and 82400025.1, with the epoxide of general formula III ##STR12## where R.sub.2 is in the .beta. position.
The 11.beta.-phenyl radical is introduced, with formation of the .DELTA..sup.9,10 -5.alpha.-hydroxy structural element, either by means of a Grignard reaction catalyzed with Cu(I), with the corresponding aryl magnesium halogenides (Tetrahedron Letters 1979, 2051), or by reaction with the mixed organocuprates of type R.sub.2 Cu(CN)Li.sub.2 (J. Amer. Chem. Soc. 103 (1981) 7672).
Access to the 13.alpha.-methyl or 13.alpha.-ethyl series (R.sub.2 is in the .alpha.-position) is gained--as described for example in European Patent Application 84730062.1 by irradiating the intermediate products of general formula IV ##STR13## with ultraviolet light.
A 9,10 epoxy or methylene group (A and B together then stand for an oxygen atom or a CH.sub.2 group) is introduced at the stage of the .DELTA..sup.9,10 -5.alpha.,17-dihydroxy-11-.beta.-phenyl phenyl intermediate product according to the methods known, in the art by conversion with, for example, hydrogen, peroxide, organic per-acids like, for example, m-chloroperbenzoic acid or perphthalic acid, tertiary butylhydroperoxide respectively with, for example, methylene iodide or methylene bromide/zink (Simmons-Smith).
The substituents R.sub.3 and R.sub.4 are introduced in accordance with the customary methods of building a C.sub.17 side chain by nucleophilic addition to the 17-ketone and subsequent reactions ("Terpenoids and Steroids", Specialist Periodical Report, The Chemical Society, London, Vol. 1-12). While the nucleophile addition to the 17-ketone of the 13.beta.-alkyl series only supplies adducts of the five-ring compound with the hydroxy group in the .beta.-position and the entering group in the .alpha.-position, the addition to the corresponding 13-epi-17-ketone generally takes place with the formation of both possible, isomeric forms at C-17, which can, however, be easily separated by chromatography or fractional crystallization. In many cases both isomers are pharmacologically effective, even if the effectiveness can differ.
The nucleophilic addition of HC.tbd.CX, in which x is hydrogen, alkyl with 1 to 4 C-atoms or halogen, is performed with the help of a compound of general formula MC.tbd.CX, in which X has the meaning indicated above and M represents an alkali metal.
The organometallic compound can be formed in situ and made to react with the 17-ketone. Thus, for example, acetylene and an alkali metal, especially potassium, sodium or lithium can be allowed to react with the 17-ketone in a suitable solvent in the presence of an alcohol or in the presence of ammonia. The alkali metal can also be in the form of, for example, methyl- or butyllithium. Dialkyl ether, tetrahydrofuran,, dioxane, benzene and toluene are especially suitable as solvents.
To manufacture the 17-chloroethinyl compound, the organometallic chloroethinyl compound is formed in situ from 1,2-dichloroethylene and an etheric alkali metal solution, examples being methyl- or butyllithium solution, and allowed to react with the 17-ketone in solvents like tetrahydrofuran or diethyl ether.
17-bromoethinyl compounds can also be manufactured by brominating the corresponding ethinyl educt (Angw. Chem. 96, 720 (1984)).
The 17-ethinyl-17-hydroxy compounds can be hydrated into the 17-acetyl-17-hydroxy compounds in an alcoholic solution with mercury catalysis (Chem. Ber. 111 (1978) 3086-3093). 3-hydroxypropine,-propene and/or propane are introduced into position 17 by converting the 17-ketone with the metallized derivatives of the propargyl alcohol, e.g. with 1-lithium-3-tetrahydropyran-2'-yloxy-propine-1, into the 17-(3-hydroxy-1-propinyl)-17-hydroxy compounds, which can subsequently be hydrated into the 17-(3-hydroxypropyl and/or 3-hydroxy-propenyl)-17-hydroxy compounds. The hydration must take place in conditions that ensure exclusively an attack on the threefold C--C bond without saturating any existing tetra-substituted 9(10) double bond. This is achieved, for example, by hydrating at room temperature and normal pressure in solvents like methanol, ethanol, propanol, tetrahydrofuran (THF) or acetic ether with the addition of noble-metal catalysts like platinum or palladium.
The homologous hydroxyalkine, hydroxyalkene and hydroxyalkane groups are introduced in corresponding fashion with homologues of the propargyl alcohol.
The compound with the Z-configurated double bond in the hydroxypropenyl group results from hydration 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). Possible deactivated noble-metal catalysts are, for example 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 hydration is stopped after one equivalent of hydrogen is taken up.
The compound with the E-configurated double bond in the hydroxypropenyl group results from reduction of the acetylenic triple bond in the generally known way. The literature describes a whole number of methods for converting alkines into transolefins, for example reduction with sodium in liquid ammonia (J. Am. Chem. Soc. 63 (1941) 216), with sodium amide in liquid ammonia (J. Am. Chem. Soc. 1955, 3558), with lithium in low-molecular weight amines (J. Am. Chem. Soc. 77 (1955) with boranes (J. Am. Chem. Soc. 93 (1971) 3395 and 94 (1972) 6560), with diisobutyl aluminum hydride and methyllithium (J. Am. Chem. Soc. 89 (1967)5085)and especially with lithium aluminum hydride/alcoholate (J. Am. Chem. Soc. 89 (1967) 4245). Another possibility is reduction of the triple bond with chromium (II) sulfate in the presence of water or dimethylformamide in a weakly acid medium (J. Am. Chem. Soc. 86 (1965) 4358) as well as, in general, reduction by reaction of transition-metal compounds with change of oxidation stage.
If final products of formula I are desired with R.sub.3 /R.sub.4 in the meaning of ##STR14## the 17-(3-hydroxypropyl) compound is oxidized in the manner known in the art, for example with Jones' reagent, manganese dioxide, pyridinium dichromate, pyridinium chlorochromate, chromic acid pyridine or the Fetizon reagent silver carbonate/Celite (Compt. rend. 267 (1968) 900).
To introduce the group ##STR15## the 17-ketone is converted with tosylmethylisocyanide into the 17-nitrile compound, and methyllithium or methylmagnesium bromide is used to obtain from the 17-nitrile compound the 17-acetyl compound which supplies the desired grouping in position 17 after enolization with K-tert-butylate in tetrahydrofuran and conversion with methyl iodide.
The 17-cyanomethyl side chain is built in the manner known in the art from 17-ketone, for example by way of the 17-spiroepoxide and cracking of the spiroepoxide with HCN in accordance with Z. Chem. 18 (1978) 259-260.
The 17-hydroxyacetyl side chain is also introduced by the generally known methods, e.g. by the method described in J. Org. Chem. 47 (1982), 2993-2995.
Free hydroxy groups in position 6, 7, 15, 16 or 17 can be esterified or etherified in the generally known way.
The strains of Neurospora crassa (ATCC 9278), Nigrospora sphaerica(CBS 98469), Streptomyces platensis (NRRL 2364) and Streptomyces toyocaensis are known and, for example, have been deposited in the German collection of microorganisms under numbers DSM 894, DSM 3392, DSM 40041 and DSM 40030.
