The present invention relates to prostaglandin analogues of the general formula: ##STR1## \x9bwherein X represents cis or trans-vinylene or ethylene, Z represents \n' ##STR2## R.sup.1 represents a hydrogen atom or a straight- or branched-chain alkyl group containing from 1 to 12 carbon atoms, R.sup.2 represents a hydrogen atom or a methyl group, R.sup.3 represents a straight- or branched-chain alkylene group containing from 1 to 7 carbon atoms and R.sup.4 represents a cycloalkyl group containing from 5 to 7 carbon atoms, a grouping of the formula: ##STR3## (wherein R.sup.5 and R.sup.6, which may be the same or different, each represent a hydrogen atom or halogen atom, a trifluoromethyl group or a straight- or branched-chain alkyl group containing from 1 to 4 carbon atoms), or a grouping of the formula: ##STR4## (wherein R.sup.5 and R.sup.6 are as hereinbefore defined), or R.sup.3 and R.sup.4 together represent a straight- or branched-chain alkyl group containing from 1 to 10 carbon atoms, and (1) the double bond between C.sub.3 -C.sub.4 is trans or cis, or trans and cis, when X is cis-vinylene or ethylene, and (2) the double bond between C.sub.3 -C.sub.4 is trans, when X is trans-vinylene, and the double bond between C.sub.13 -C.sub.14 is trans! and cyclodextrin clathrates of such acids and esters, and when R.sup.1 represents a hydrogen atom, non-toxic salts thereof, which exhibit characteristic prostaglandin-like activities.
