Cyclopentane derivatives of the formula: ##STR1## wherein R.sup.1 represents hydrogen or a carboxylic acyl group, and either (I) R.sup.2 represents a group of the formula: --CR.sup.3 R.sup.4 R.sup.5 II (wherein R.sup.3 and R.sup.4 represent hydrogen or alkyl, and R.sup.5 represents hydrogen, or alkyl, alkoxy, cycloalkyl or adamantyl, or R.sup.5 represents alkyl substituted by alkoxy, or by cycloalkyl or by adamantyl, or the group --CR.sup.3 R.sup.4 R.sup.5 together forms a cycloalkyl or adamantyl group), X represents trans-vinylene or ethylene and Y represents carbonyl or a group of the formula: ##STR2## wherein R.sup.6 represents hydrogen or alkyl, and R.sup.7 represents hydrogen or a carboxylic acyl group, or else (ii) R.sup.2 represents a group of the formula: --A-Z-R.sup.8 IV (wherein A represents alkylene, Z represents a direct bond or oxygen or sulphur, and R.sup.8 represents an aryl or heterocyclyl group which may be substituted by one or more of halogen, alkyl, alkoxy and trihalomethyl), X in formula I represents ethylene or trans-vinylene and Y in formula I represents carbonyl or a group of formula III, or else (iii) R.sup.2 represents a group R.sup.8 and X and Y in formula I represent simultaneously ethylene and carbonyl, trans-vinylene and carbonyl, or ethylene and --CH(OR.sup.7)-- groups respectively. The compounds are new and possess pharmacological properties similar to those of prostaglandins.
