The present invention relates to prostaglandin analogues of the general formula: ##STR1## [wherein A represents a grouping of the formula: ##STR2## X represents trans-vinylene or ethylene and Y represents cis-vinylene or ethylene, R represents a group of the formula --COOR.sup.4, in which R.sup.4 represents hydrogen or straight- or branched-chain alkyl of 1 to 12 carbon atoms, or a group of the formula --CH.sub.2 OR.sup.5, in which R.sup.5 represents hydrogen or alkylcarbonyl of 2 to 5 carbon atoms and R.sup.1, R.sup.2 and R.sup.3, which may be the same or different, each represent hydrogen, straight- or branched-chain alkyl of 1 to 12 carbon atoms, or an aryl group unsubstituted or substituted by one, two or three substituents selected from alkyl, alkoxy, alkylthio, monoalkylamino and dialkylamino groups and halogen atoms, the alkyl groups or moieties of the said groups containing from 1 to 5 carbon atoms in a straight- or branched-chain, with the proviso that at least one of the symbols R.sup.1, R.sup.2 and R.sup.3 is other than hydrogen and the double bond between C.sub.2 -C.sub.3 is trans] and cyclodextrin clathrates of such prostaglandin analogues and, when R.sup.4 in the group - COOR.sup.4 represents hydrogen, non-toxic salts thereof, which exhibit characteristic prostaglandin-like activities.
本发明涉及一般式的前列腺素类似物:##STR1## [其中A代表下列式的一个分组:##STR2## X代表反式乙烯基或乙烯基,Y代表顺式乙烯基或乙烯基,R代表下列式的一个群--COOR.sup.4,在其中R.sup.4代表氢或1到12个碳原子的直链或支链烷基,或下列式的一个群--CH.sub.2 OR.sup.5,在其中R.sup.5代表氢或2到5个碳原子的烷基羰基,而R.sup.1、R.sup.2和R.sup.3,可以相同也可以不同,每个代表氢、1到12个碳原子的直链或支链烷基,或一个芳基,未取代或取代,取代基包括烷基、烷氧基、烷硫基、单烷基胺基和二烷基胺基群以及卤素原子,所述群的烷基基团或部分含有1到5个碳原子的直链或支链,但至少其中一个符号R.sup.1、R.sup.2和R.sup.3不是氢,C.sub.2 -C.sub.3之间的双键是反式的]以及这种前列腺素类似物的环糊精包结合物,当群- COOR.sup.4中的R.sup.4代表氢时,它们的无毒盐,表现出特征性的前列腺素样活性。
