Description

BRIEF SUMMARY OF THE INVENTION

This invention relates to novel 16-aryloxy-17,18,19,20-tetranorprostanoic acids, their derivatives and intermediates for preparing same. More specifically the novel compounds of this invention can be represented by the following two general formulae wherein A has the same absolute configuration as is found in the naturally-occurring mammallian prostaglandins, and all the racemates, racemic mixtures and diasteromeric mixtures thereof. ##STR1## wherein R.sub.1 is hydroxy or an alkoxy group having from one to twelve carbon atoms; R.sub.2 is a phenyl, benzyl, naphthyl, or 5,6,7,8-tetrahydronaphthyl group optionally substituted with one or two of the following groups: halogen, lower alkyl, lower alkoxy, or trifluoromethyl radicals; n is an integer having the value 2 to 4, inclusive; Y is a divalent radical selected from the group consisting of ##STR2## X is a divalent radical selected from the group consisting of ##STR3## C.sub.5 -C.sub.6 is ethylene or cis-vinylene; C.sub.13 -C.sub.14 is ethylene or trans-vinylene; with the proviso that when C.sub.5 -C.sub.6 is cis-vinylene then C.sub.13 -C.sub.14 is trans-vinylene.

When X is ##STR4## it represents the 15.alpha.-hydroxy derivative, and the 15.beta.-hydroxy derivatives when it is ##STR5##

Suitable lower alkyl and lower alkoxy groups contemplated by the present invention are those having up to four carbon atoms such as, for example, methyl, propyl, iso-propyl, n-butyl, sec-butyl, methoxy, ethoxy, t-butoxy, etc.

Also embraced within the scope of the present invention are the non-toxic, pharmaceutically acceptable salts of the novel compounds of the present invention when R.sub.1 is hydroxy. The cations comprised in these salts include, for example, the non-toxic metal cations such as the sodium ion, potassium ion, calcium ion, and magnesium ion as well as the organic amine cations such as the tri(lower alkyl)amine cations (e.g., triethylamine), procaine, and the like.

The novel compounds of the present invention are obtainable as yellow oils or crystalline solids having characteristics absorption spectra. They are relatively insoluble in water but are relatively soluble in common organic solvents such as ethanol, ethyl acetate, dimethylformamide, and the like. The cationic salts of the compounds when R.sub.1 is hydroxy are, in general, white to yellow crystalline solids having characteristic absorption spectra. They are relatively soluble in water, methanol and ethanol but are relatively insoluble in benzene, diethyl ether, and petroleum ether.

DETAILED DESCRIPTION OF THE INVENTION

The prostaglandins are a family of closely related compounds which have been obtained from various animal tissues, and which stimulate smooth muscle, lower arterial blood pressure, antagonize epinephrine-induced mobilization of free fatty acids, and have other pharmacological and autopharmacological effects in mammals. See Bergstrom et al., J. Biol. Chem., 238, 3555 (1963) and Horton, Experienta, 21, 113 (1965) and references cited therein. All of the so-called natural prostaglandins are derivatives of prostanoic acid. ##STR6## The hydrogen atoms attached to C-8 and C-12 are in trans configuration. The natural prostaglandins represent only one of the possible optical isomers. The compounds of this convention include all possible optical isomers.

The novel compounds of this invention are prepared from the corresponding known 11.alpha.-hydroxy-9-oxo-5-cis,13-trans-prostadienoic acids (I) (Netherlands Pat. No. 7,206,361; Nov. 14, 1972) as illustrated in Flowsheet A which follows and in which n, R.sub.2 and C.sub.5 -C.sub.6 are as hereinabove defined and in which THP is the tetrahydropyranyl group. ##STR7##

According to Flowsheet A above, dehydration of (I) in the usual manner provides the 16-aryloxy-15.alpha.-hydroxy-9-oxo-17,20-tetranor-5-cis,10,13-trans-prostatrienoic acids (III) which upon treatment with dihydropyran and acid provide the bistetrahydropyranyl derivative (V). Upon treatment of (V) with sodium borohydride or sodium cyanoborohydride (pH3-4), a mixture (VII) of 9.alpha.,15.alpha.-dihydroxy-16-aryloxy-9-oxo-17,20-tetranor-5-cis,13-trans-prostadienoic acid and the corresponding 9.alpha.-hydroxyl prostadienoic acid is obtained. Oxidation of the 9-hydroxy mixture (VII) provides, after acidic hydrolysis of the tetrahydropyranyl functions, the 16-aryloxy-15.alpha.-hydroxy-9-oxo-17,20-tetranor-5-cis,13-trans-prostadienoic acid (VIII), which upon hydrogenation provides the fully saturated 16-aryloxy-15.alpha.-hydroxy-9-oxo-17,20-tetranorprostanoic acids (IX).

Treatment of the 16-aryloxy-11.alpha.,15.alpha.-dihydroxy-17,20-tetranor-5-cis,13-trans-prostadienoic acids (I) with dihydropyran and an acid catalyst provides the tris-tetrahydropyranyl derivatives (II) which can be selectively reduced at the C.sub.5 -C.sub.6 cis double bond. Acid-catalyzed hydrolysis of the tetrahydropyranyl moieties then provides the 11.alpha.,15.alpha.-dihydroxy-9-oxo-16-aryloxy-17,20-tetranor-13-trans-prostenoic acids (IV), which when subjected to the steps as described above for I.fwdarw.III.fwdarw.V.fwdarw.VII.fwdarw.VIII provides the 15.alpha.-hydroxy-9-oxo-16-aryloxy-17,20-tetranor-13-trans-prostenoic acids of this invention.

The 9-hydroxy derivative of this invention can also be obtained by reduction of the corresponding 9-oxo derivative. When the reduction is carried out in the usual manner with sodium borohydride in ethanol as solvent, the product is a mixture of the 9.alpha.- and 9.beta.-hydroxy derivative (X) and (XI), respectively. These isomers are separable by chromatographic procedures. The stereoselective preparation of the 9.alpha.-hydroxy derivative (X) can be accomplished by reduction of the 9-oxo derivative with either lithium perhydro-9b-boraphenalyl hydride [H. C. Brown and W. C. Dickason, Jour. Amer. Chem. Soc., 92, 709 (1970)] or with lithium tri-sec-butylborohydride. ##STR8##

The carboxylic acid esters (R.sub.1 =alkoxy) of this invention can be prepared by treating the corresponding carboxylic acid with the appropriate diazoalkane by the usual procedures well known to the art. An alternative procedure involves blocking the 15-hydroxy function with a tetrahydropyranyl group, conversion of the carboxylic acid to an acid chloride and reacting with the appropriate alcohol in the presence of an acid-acceptor and deblocking.

All of the compounds of this invention can be isolated and purified by conventional methods. Isolation can be accomplished, for example, by dilution of the reaction mixture with water, extraction with a water-immiscible solvent such as methylene chloride, ethyl acetate, benzene, cyclohexane, ether, toluene and the like, chromatography, adsorption on ion-exchange resins, distillation, or a combination of these. Purification of the compounds of this invention can be accomplished by means known in the art for the purification of prostaglandins and lipids, fatty acids, and fatty esters. For example, partition chromatography, reverse phase partition chromatography, countercurrent distribution, adsorption chromatography on acid washed Florisil.RTM. (synthetic magnesium silicate) and acid washed silica gel, dry column chromatography, preparative paper chromatography, preparative thin layer chromatography, chromatography over sili-ca loaded cation exchange resins, and combinations thereof can be used effectively to purify the compounds produced by the presence of this invention.

If a compound of this invention is prepared from a prostaglandin A (III, V, VI) which is in the optically active resolved from, then the product will also be in the resolved form. On the other hand, if the prostaglandin A is racemic, the product will be racemic.

In formulae XII-XXIII, which follow, R.sub.2, n, X, C.sub.5 -C.sub.6 and C.sub.13 -C.sub.14 are as hereinabove defined.

The racemic products and intermediates of this invention may be resolved into their optically active components by a number of methods of resolution well known in the art. For example, the free carboxylic acids can be treated with an optically active base such as cinchonine, quinine, brucine, d- or l-.alpha.-phenylethylamine and the like to produce diastereoisomeric salts which can be separated by crystallization. Alternatively, the acid may be esterified with an optically active alcohol, e.g., di- or l-menthol, estradiol 3-acetate, etc., and the diastereoisomeric esters then resolved.

Resolution of the racemic prostaglandin-like compounds of this invention may also be accomplished by reverse phase and absorption chromatography on an optically active support and adsorbent and by selective transformation of one isomer with a biologically-active prostaglandin, transforming system. Such transformations can be carried out by incubation or perfusion, using methods well established in the art, followed by isolation and recovery of the isomer resistant to the metabolic transformation applied.

Additional procedures for effecting the resolution of the racemic products of this invention involve conversion of a 9.alpha.-hydroxy racemate (illustrated by XII and XIII below) to the corresponding hemiphthalate (e.g., XIV) and conversion of this diacid to a bis salt (e.g., XV) with an optically active amine (e.g., 1-(-)-.alpha.-methylbenzylamine, d-(+)-.alpha.-methylbenzylamine, brucine, dehydroabietylamine, strychnine, quinine, cinchonine, cinchonidine, quinidine, ephedrine, deoxyephedrine, amphetamine, (+)-2-amino-1-butanol (-)-2-amino-1-butanol and the like). The resulting diastereoisomers are then separated by fractional crystallization and the individual components are then converted by acidification and saponification to the individual optically active parent 9.alpha.-hydroxy enantiomers (XII) and (XIII), oxidation of which provides the corresponding individual 9-oxo enantiomers (XVI) and (XVII). ##STR9##

Another procedure involves conversion of the 9.alpha.-hydroxy racemate (as the 15-hydroxy blocked and then deblocked prostenoic acid ester) to the diastereomeric carbamates with an optically active isocyanate, e.g., (+)-1-phenylethylisocyanate and (-)-1-phenylethylisocyanate. Separation of the diastereomers, for example, (XVIII) and (XIX), can be accomplished by fractional crystallization or by the usual chromatographic procedures, or if necessary by high speed liquid chromatography involving, if required, recycling techniques [See G. Fallick, American Laboratory, 19-27 (August, 1973) as well as references cited therein. Additional information concerning high speed liquid chromatography and the instruments necessary for its application is available from Waters Associates Inc., Maple St., Milford, Mass.] Base-treatment of the individual diastereomeric carbamates then affords the individual enantiomeric alcohols. ##STR10##

It is also possible to effect resolution of the 9.alpha.-hydroxy racemate, preferably as the prostenoate ester, by esterification of the 9.alpha.-hydroxy function (15-hydroxy function blocked as a tetrahydropyranyl ether or trimethylsilyl ester and then deblocked after 9.alpha.-hydroxyfunctionally action) with an optically active acid, via its acid chloride. Suitable optically active acids include .omega.-camphoric acid, menthoxyacetic acid, 3.beta.-acetoxy-.DELTA..sup.5 -etianic acid, (-)-.alpha.-methoxy-.alpha.-trifluoromethylphenyl acetic acid and (+)-.alpha.-methoxy-.alpha.-trifluoromethylphenylacetic acid, and the like. The resulting diastereoisomeric esters, for example (XX) and (XXI) are then separated by fractional crystallization or by chromatographic techniques including if necessary, the use of high speed liquid chromatography. Saponification of the individual diastereoisomers then provides the individual 9.alpha.-hydroxyprostenoic acid enantiomers (XII) and (XIII). ##STR11##

Another resolution procedure involves derivatization of the keto function of the racemic 9-oxoprostenoic acid or ester with the usual type of ketone derivatizing agents bearing an optically active center. The resulting mixture of diastereomeric derivatives can then be separated by fractional crystallization or by chromatography or, if necessary, by high speed liquid chromatography. The individual diastereomeric keto derivatives, for example, (XXII) and (XXIII), are then convertable to the individual 9-oxo enantiomers (XVI) and (XVII) by any of the usual cleavage techniques. Ketone reduction of the 9-oxo-enantiomer as described hereinabove then provides the corresponding 9.alpha.-hydroxy or 9.beta.-hydroxy enantiomer. Among the optically active reagents useful for ketone derivatization are 1-.alpha.-aminoxy-.gamma.-methylpentanoic acid hydrochloride [E. Testa et al., Helv. Chimica Acta, 47 (3), 766 (1973)], menthylhydrazine, and 4-.alpha.-methylbenzylsemicarbazide. ##STR12##

Other useful keto derivating agents are optically active 1,2-glycols, e.g., D(-)-2,3-butanediol, [for pertinent literature see, A. C. Neish, Can. Jour. Res. 23 sec. B, 10 (1945); G. E. Ward et al., Jour. Amer. Chem. Soc., 66, 541 (1944); J. Casanova, Jr. and E. J. Corey, Chem. and Ind. (London), 1961, 1964)] or optically active dithiols, e.g., L(+)-2,3-butanedithiol [see also E. J. Corey and R. B. Miha, Jour. Amer. Chem. Soc., 84, 2938 (1962)].

The novel compounds of this invention are useful as hypotensive agents (9-oxo derivatives), bronchodilators for the treatment of asthma and as agents for the control of reproduction in females, in humans as well as in warm-blooded animals such as cattle, sheep, swine, horses, dogs and cats. Among the potential uses in domestic animals is the synchronization of oestrus in cattle and other domestic animals, and the induction of twinning.

In humans these compounds may have use as agents for the induction of labor at term, as abortifacients and as menses inducers.

There are several possibilities of contraceptive attack during the normal processes of mammalian female reproduction. These include any others ovulation blockage, interference with the fertilization of the ovum by sperm, interference with the normal transport of ova and or zygotes in the reproductive tract, prevention of embryo implantation, disruption of the maternal response to embryonic implantation, and maternal failure to support embryonic survival. While the exact mechanism or mechanisms which take place with the active ingredients in effecting contraception is not clear, the compounds of this invention may prevent conception by one or more of the above-mentioned occurrences. It is not intended, however, that the present invention be limited to any particular theory as to mechanism of contraception.

A major problem in the clinical use of prostaglandin E.sub.2 and prostaglandin F.sub.2 .alpha., and indeed of prostaglandins of the 11.alpha.-hydroxy series in general, is the often high incidence of gastrointestinal side-effects as manifested by nausea, vomiting and diarrhea. Presumably, these effects result from the stimulation of gastrointestinal smooth muscle by the administered prostaglandin. One important advantage of the compounds of this invention is that although they retain to a significant extent the antifertility potency of the parent 11-hydroxy compounds they show a highly diminished ability to stimulate smooth myscle. This very significant and unanticipated separation of biological effects suggests that the compounds of this invention have the potential to be useful anti-fertility agents with a minimum of adverse side-effects. It is also conceivable that this separation will allow the use of higher relative doses of these compounds than hitherto possible with the established prostaglandins. This also denotes the possibilities of more effective application in the field of post-conception control, e.g. inducing menses during approximately the first two weeks following the first missed menstruation. For a discussion of these problems see Toppozada et al. "Prostaglandins in Fertility Control" 3, 108 (1973), Report from Meetings of the Prostaglandin Task Force Steering Committee sponsored by the World Health Organization; and Wiqvist et al., ibid. 3, 83 (1973).

The invention will be described in greater detail in conjunction with the following specific examples.

EXAMPLE 1

Preparation of d,l-11.alpha.,15.alpha.-dihydroxy-9-oxo-16-phenoxy-17,20-tetranor-5-cis-13-trans-prostadienoic acid

A mixture of the 15 epimers of dl-16-phenoxy-9.alpha.,11.alpha.,15-trihydroxy-17,20-tetranor-5-cis-13-trans-prostadienoic acid is prepared in accordance with Netherlands Pat. No. 7,206,361, page 9, Example 1. The two epimers are separated by the procedure of Netherlands Pat. No. 7,206,361, page 9, Example 1. The high Rf material is assigned the 15.beta. configuration and the low Rf material is assigned the 15.alpha.-configuration. dl-16-Phenoxy-9.alpha.,11.alpha.,15-trihydroxy-17,20-tetranor-5-cis-13-trans-prostadienoic acid (100 mg.) is dissolved in 2.0 ml. of dry acetone and stirred at -40.degree. C. under argon, N-trimethylsilyldimethylamine (3 ml.) is then added and after 1 hour the reaction is diluted with cold ether and extracted with 50% saturated aqueous sodium bicarbonate. Evaporation to dryness in vacuo yields as the major product: dl-11.alpha.,15.alpha.-bistrimethylsiloxy-9.alpha.-hydroxy-16-phenoxy-17,20-tetranor-5-cis-13-trans-prostadienoic acid trimethylsilyl ester.

The crude material is oxidized with Collins reagent (prepared in situ from 170 mg. of chromic anhydride and 275 ml. of pyridine in 4 ml. of methylene chloride) for 5 minutes at 25.degree. C. The reaction mixture is diluted with ether and extracted with 0.5 M hydrochloric acid washed with brine. The organic solution is dried with magnesium sulfate and concentrated in vacuo to give the crude dl-11.alpha.,15-bistrimethylsiloxy-9-oxo-16-phenoxy-17,20-tetranor-5-cis-13-trans-prostadienoic acid trimethylsilyl ester.

The crude trimethylsilyl ester is dissolved in 5 ml. of methanol containing 0.5 ml. of water and 0.25 ml. of acetic acid and stirred at ambient temperature for 1 hour. The solution is diluted with 5 ml. of 30% aqueous potassium hydrogen phosphate and extracted twice with 10 ml. of ether. The ether is dried with magnesium sulfate and concentrated in vacuo to afford dl-11.alpha.,15.alpha.-dihydroxy-9-oxo-16-phenoxy-17,20-tetranor-5-cis-13-trans-prostatrienoic acid as an oil.

The crude oil is purified by dry column chromatography on silica gel to give dl-11.alpha.,15.alpha.-dihydroxy-9-oxo-16-phenoxy-17,20-tetranor-5-cis-13-trans-prostatrienoic acid.

EXAMPLE 130

Preparation of dl-11-deoxy-15.alpha.-hydroxy-9-oxo-16-phenoxy-17,20-tetranor-5-cis,13-trans-prostadienoic acid

150 mg. of dl-15.alpha.-hydroxy-9-oxo-16-phenoxy-17,20-tetranor-5-cis,10,13-trans-prostatrienoic acid (Example 66) in 10 ml. of ether is esterified with excess diazomethane in ether. Evaporation of the ether gives dl-15.alpha.-hydroxy-9-oxo-16-phenoxy-17,20-tetranor-5-cis,10,13-trans-prostatrienoic acid methyl ester.

The crude methyl ester is dissolved in 10 ml. of benzene and 7 ml. of a 1 N solution of acetic anhydride-pyridine in benzene is added. After 24 hours 5 ml. more of 1 N acetic anhydride-piperidine is added and stirred. After an additional 24 hours, 5 ml. more of 1 N acetic anhydride-pyridine is added and stirred 72 hours or until TLC indicates no starting material present. The volume of the reaction is reduced to 10 ml. in vacuo on a rotary evaporator. The reaction product is chromatographed on acid washed silica-gel with ethyl acetate-benzene to provide dl-15.alpha.-acetoxy-9-oxo-16-phenoxy-17,20-tetranor-5-cis,10,13-trans-prostatrienoic acid methyl ester as an oil.

The crude methyl ester is dissolved in 3 ml. of ethanol at 0.degree. C. and is treated dropwise with a cold solution of 230 mg. of sodium borohydride in 3 ml. of ethanol containing 0.3 ml. of water. After 15 minutes, 0.25 ml. of acetic acid and 10 ml. of water is added, and the mixture is extracted with 50 ml. of methylene chloride. The organic extract is washed with sodium bicarbonate, dried with magnesium sulfate, and concentrated in vacuo to given an oil.

The crude oil is dissolved in 8 ml. of acetone and cooled to -5.degree. C. Then 0.3 ml. of Jones chromic oxide mixture is added slowly and after 15 minutes 0.1 ml. of isopropanol is added.

After 5 minutes the solution is diluted with 25 ml. of methylene chloride and washed with 20 ml. of water. The methylene chloride is dried with magnesium sulfate and concentrated in vacuo to give the crude mixture as an oil.

The oil is purified on acid washed silica-gel using benzene-ethyl acetate to give dl-15.alpha.-acetoxy-11-deoxy-9-oxo-16-phenoxy-17,20-tetranor-5-cis,13-trans-prostadienoic acid methyl ester as an oil.

To 50 mg. of the methyl ester in 2 ml. of methanol is added 1 ml. of 2.5 N aqueous sodium hydroxide. After stirring for 8 hours, the solution is acidified with 30% aqueous sodium dihydrogen phosphate, saturated with sodium chloride, and extracted with ether. The ether extracts are dried with magnesium sulfate and concentrated in vacuo to give dl-11-deoxy-15.alpha.-hydroxy-9-oxo-16-phenoxy-17,20-tetranor-5-cis,13-trans-prostadienoic acid; 3400, 1735, 1710, 975 cm.sup.-1.
