Abstract
Prostane derivatives have the following formula in which the substituents are defined in Claim 1. The novel compounds are prepared by appropriately esterifying corresponding prostan-1-ols in which free OH groups, with the exception of the 1-OH group, have optional intermediate protection. A further process is based on the reaction of the prostan-1-ols with isocyanates or with carbamoyl chlorides. The novel prostane derivatives are used in medicaments. They can be used for inducing an abortion, for cycle control, for induction of labour or for the treatment of hypertension.
Description
This invention relates to prostane derivatives, a process for their production and their use as medicaments.
It is known from the very comprehensive prior art concerning prostaglandins and their analogues that, because of their biological and pharmacological properties, this class of substance is suitable for the treatment of mammals, including human beings. However, their use as medicaments is often faced with difficulties. Most natural prostaglandins have a duration of action which is too short for therapeutic purposes since they are decomposed metabolically too rapidly by various enzymatic processes. The production of derivatives of prostanoic acid has therefore gained great importance.
All structural alterations have aimed at increasing the duration of action and also the selectivity of effect!veness.
The present invention provides a prostane derivative of the general formula
wherei η
Rj represents an acyl radical of an organic carboxylic or sulphuric acid preferably having from 1 to 15 carbon atoms or a group obtainable from an oxygen-containing inorganic acid by removal of a hydroxy group or a
-C-N \

D represents an alkylene group having from 1 to 5 carbon atoms or a -C=C- group, and
E represents an oxygen or sulphur atom or a direct bond,
R3 represents an aliphatic hydrocarbon radical, preferably an alkyl group, which may be • unsubstituted or substituted by a cycloalkyl, alkylsubstituted cycloalkyl, unsubstituted or substituted aryl or heterocyclic group, a cycloalkyl or alkyl15 substituted cycloalkyl group, or an unsubstituted or substituted aryl or heterocyclic group, e.g. a benzodioxol-2-yl group, and
Z represents a free or ketalised carbonyl group or a free esterified or etherified hydroxymothylene group in which the free esterified or etherified hydroxy group may be in the a- ore-configuration.
It will be understood that the structural formulae and
- 6 written nomenclature of the compounds described and claimed herein include the optical antipodes and the racemates of the compounds, and where appropriate, geometrical isomeric forms.
The present invention also provides a salt of a compound of the general formula I, especially a physiologically tolerable salt.
Compounds of the general formula I and physiologically tolerable salts thereof have useful pharmacological properties.
An acyl radical represented by Rp or Rg or the group obtainable from an inorganic acid represented by is preferably a physiologically tolerable radical.
Preferred acids from which the acyl radicals are derived 15 are organic carboxylic acids and sulphonic acids having from 1 to 15 carbon atoms which belong to the aliphatic, cycloaliphatic, aromatic, aromatic-aliphatic, cycloaliphatic-aliphatic, heterocyclic or heterocyclicaliphatic series. These acids may be saturated or unsaturated, mono, di- or poly-basic, unsubstituted or substituted. Examples of the substituents are halogen atoms and alkyl, hydroxy, carboxy, alkoxy, phenoxy, oxo and amino groups and amino groups substituted, for example, by one or two alkyl groups or by an alkylene
- 7 group which may be interrupted by a hetero atom. One or more of the same or different substituents may be present in the acid and a substituent itself may be substituted, for example by an alkyl substituent or by a halogen atom or atoms.
The following carboxylic acids may be mentioned by way of example: formic acid, acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, isovaleric acid, caproic acid, oenanthic acid, caprylic acid, pelargonic acid, capric acid, undecyclic acid, lauric acid, tridecyclic acid, myristic acid, pentadecyclic acid, trimethylacetic acid, diethylacetic acid, iar*.butylacetic acid, cyclopentylacetic acid, cyclohexylacetic acid, cyclohexanecarboxylic acid, phenylacetic acid, phenoxyacetic acid, methoxyacetic acid, ethoxyacetic acid mono-, di- and trichloroacetic acid, aminoacetic acid, diethylaminoacetic acid, piperidinoacetic acid, morpholinoacetic acid, lactic acid, succinic acid, adipic acid, benzoic acid, benzoic acids substituted by one or more halogen atoms or by one or more trifluoromethyl, hydroxy, alkoxy or carboxy groups, nicotinic acid, isonicotinic acid, furan-2-carboxylic acid and cyclopentylpropionic acid.
Suitable sulphonic acids are, for example, methanesulphonic acid, ethanesulphonic acid, isopropanesulphonic acid, β-chloroethanesulphonic acid,
- 8 butanesulphonic acid, cyclopentanesulphonic acid, cyclohexanesulphonic acid, benzenesulphonic acid, p-toluenesulphonic acid, p-chlorobenzenesulphonic acid, p-methoxybenzenesulphonic acid, N,N-dimethylaminosulphonic acid, Ν,Ν-diethylaminosulphonic acid, N,N-bis-(8-chloroethyl) - aminosulphonic acid, N,N - diisobutylaminosulphonic acid, N,N - dibutylaminosulphonic acid, and pyrrolidino-, piperidino, piperazino-, N-methylpiperazino-, thiophenoand morpholinosulphonic acid.
For Ry acyl radicals having up to 10 carbon atoms are especially preferred and for R^ or Rg acyl radicals having up to 6 carbon atoms are especially preferred.
Further, for derivation of radicals represented by Rj, the usual inorganic acids, for example sulphuric and phosphoric acid, are suitable.
The group represented by
is an unsubstituted or substitued carbamoyl or thiocarbamoyl radical. The carbamoyl or the thiocarbamoyl group may be substituted at the nitrogen atom by an unsubstituted or substituted alkyl, cycloalkyl, aryl, aromatic heterocyclic or acyl radical of an organic carboxylic or sulphonic acid or by two such groups, R^ and Rg. Preferred
C-N groups are unsubstituted and substituted carbamoyl groups.
Suitable alkyl groups represented by R^ and Rg are, for example, straight- and branched-chain alkyl groups having from 1 to 10 carbon atoms, e.g. methyl, ethyl, propyl,

wherein R^ and Rg have the meanings given above, and then, if desired, one or more of the following steps is carried
out where appropriate in any desired order: (T) a protected hydroxy group is converted to a 5 free hydroxy group; (ii) a free hydroxy group is oxidised, esterified or etherified; (iii) a free carbonyl group is ketalised or reduced; (iv) a ketalised carbonyl group is converted to a 10 free oxo group; (v) a multiple bond is hydrogenated;
- 17 (vi) a compound of the general formula I is converted into a salt thereof or a salt is converted into a free compound of the general formula I;
(vii) a mixture of epimers is separated.
The alcohol of the general formula II may be esterified in a manner known per se. For example, esterification may be effected by reacting the alcohol with an acid derivative, preferably an acid halide or acid anhydride, in the presence of a base, for example sodium nydride, pyridine, triethylamine, tributylamine or 4-dimethylaminopyridine.
The reaction may be carried out without a solvent or in an inert solvent, preferably acetone, acetonitrile, dimethylacetamide or DMSO, at a temperature above or below room temperature, for example from -80 to 100°C, preferably at room temperature.
The alcohol of the general formula II may be reacted with a compound of the general formula III or IV in a manner known per se. For example, the reaction may be carried out in the presence of a tertiary amine, for example triethylamine or pyridine, and without a solvent or in an inert solvent, preferably acetone, acetonitrile, dietmylacetamide, methylene chloride, tetrahydrofuran, ether, benezene, toluene or DMSO, at a temperature above or below room temperature, for example from -80 to 100°C, preferably at 0 to 30°C.
If the starting material contains additional OH groups in
-lain the prostane radical apart from the 1-positioned OH group, these OH groups are also esterified by the process. If the end product of formula I desired should have a free hydroxy group or groups, the corresponding group or groups in the starting material are preferably protected, preferably by formation of an easily-cleavable ether group or groups.
A functionally converted hydroxy group (esterified or etherified) in the product of formula I may be deprotected released according to known methods. For example, the hydroxy-protecting groups, such as, for example, the tetrahydropyranyl radical, may be cleaved in an aqueous solution of an organic acid, e.g. acetic acid or propionic acid, or in an aqueous solution of an inorganic acid, e.g. hydrochloric acid or tetrabutylammonium fluoride. A water-miscible inert organic solvent is advantageously added to improve the solubility. Suitable organic solvents are, for example, alcohols, e.g. methanol and ethanol, and ethers, e.g. 1,2-dimethoxyethane, dioxan and tetrahydrofuran. Tetrahydrofuran is preferably used.
Cleaving is preferably effected at a temperature of from 20 to 80°C.
A hydroxy group present may then be esterified or etherified or oxidised according to methods known per se with the usual esterification, etherification or oxidising agents.
- 19 For example, the 9-hydroxy group may be oxidised to form the ketone with Jones reagent (J. Chem. Soc. 1953, 2555), the operation being effected with an excess of the oxidising agent in a suitable diluent, for example acetone, at a temperature of from 0 to - 50°C, preferably at substantially - 20°C. The reaction is generally complete after 5 to 30 minutes. Oxidation is preferably effected after the intermediate protection of the 15-hydroxy group by silylation. (Chem.Comm. 1972, 1120). Silylation may be effected, for example, with Ν,Ν-diethyltrimethylsilylamine in acetone at - 70 to +20°C, preferably at -40 to 0°C.
Other suitable oxidising agents are silver carbonate on Celite” (Trade Mark) or Collins reagent (Tetrahedron Letters 1968, 3363).
Ketalisation may be effected in a manner known per oe.
For example, the ketone may be heated with ethylene glycol in the presence of an acid catalyst with the separation of water. P-Toluenesulphonic acid and perchloric acid are particularly suitable as acid catalyst.
A 9-oxo group may be reduced using a conventional reducing agent, for example with sodium borohydride, lithium tritert.-butoxy aluminium hydride, zinc borohydride or aluminium isopropoxide in the presence of an alcohol, or potassium tri-sea.-butyl borohydride, preferably with sodium borohydride at a temperature of from -50 to +50°C, preferably 0 to 20°C. Suitable solvents for this .46864 reaction, depending on the reducing agent used, are methanol, ethanol, isopropanol, diethyl ether, dioxan and tetrahydrofuran. When reducing with sodium borohydride, methanol, ethanol· or isopropanol are preferably used. The resulting a- and β-ΟΗ-epimer mixture may be separated in the normal manner by column or layer chromatography.
Hydrogenation of a C=C double bond contained in the primary product, which may also be desired, may be effected according to a method known per se.
The alcohol of the general formula II used as the starting material for the above process may be produced, for example by reacting an aldehyde of the general formula /

Prostane derivatives of the general formula I and their physiologically tolerable salts are useful drugs since, with a comparable range of action, they have a considerably improved action (higher degree of specificity) and, above all, considerably longer-lasting action than the corresponding natural prostaglandins. In comparison to PGE and PGA derivatives the 11-deoxyprostaglandins of the invention are also distinguished by greater stability.
Furthermore, the compounds have an improved antiferti1ity activity. Considerably smaller quantities of the prostane derivatives are therefore necessary in comparison to the natural prostaglandins for inducing abortions in non-human animals
When recording the isotonic contraction of the uterus of narcotised rats and of the isolated uterus of rats or guinea pigs the compounds of the invention proved to be
- 28 considerably more effective and their effects were longerlasting than in the case of the natural prostaglandins.
In the case of some of the prostane derivatives of the invention a single intrauterinal or vaginal application indices menstruation or interrupts a pregnancy. In addition, some of the compounds have luteolytic action and are non-human suitable for synchronising the sexual cycle of/female mammals, e.g. apes, horses, cattle and pigs.
The good tissue specificity of the substances according to the invention having antifertile and hypotensive action is demonstrated in the investigation of other unstriated organs, such as, for example, the ileum of guinea pigs or the isolated rabbit trachea, where considerably less stimulation is to be observed than that caused by the natural prostaglandins.
Many of the active substances of the invention, when used on the isolated rabbit trachea in vitro, even have a bronchodilatory action and greatly inhibit the secretion of gastric acid. The compounds having diuretic and hypotensive action also have a regulating effect in cases of disturbances of the cardiac rhythm. In contrast, their effect on other organ systems is very slight.
Accordingly, the present invention provides a pharmaceutical preparation which comprises a compound of the general formula I or a physiologically tolerable salt thereof, in
- 29 admixture or conjunction with a pharmaceutically suitable carrier.
The preparation may be in a form suitable for inhalation, oral, parenteral or local (for example vaginal) administration, and may, for example, be in dosage unit form containing, for example 0.01 to 25 mg of active ingredient per dosage unit.
For inhalation, aerosol solutions are preferably produced.
Tablets, dragees or capsules, for example, are suitable for oral administration.
Sterile, injectable, aqueous or oily solutions are used for parenteral administration.
Suppositories, for example, are suitable and customary for vaginal administration.
The active substance of the invention may be used together with the auxiliary substances which are known and conventional in galenical pharmacy, for example for the production of preparations for the inducement of abortions, for the control of the sexual cycle, for inducing birth or for the treatment of hypertension.
