The present invention relates to compounds of the formula: ##STR1## wherein A represents a grouping of the formula: ##STR2## B represents an oxygen or sulphur atom, R.sup.1 and R.sup.2, which may be the same or different, each represent a hydrogen or halogen atom, a trifluoromethyl group, or a straight- or branched-chain alkyl or alkoxy group containing from 1 to 4 carbon atoms, R represents a group of the formula --COOR.sup.3, in which R.sup.3 represents a hydrogen atom or a straight- or branched-chain alkyl group containing from 1 to 12 carbon atoms, or a group of the formula --CH.sub.2 OR.sup.4, in which R.sup.4 represents a hydrogen atom or an alkylcarbonyl group containing from 2 to 5 carbon atoms and the double bonds depicted in positions C.sub.2 -C.sub.3, C.sub.5 -C.sub.6 and C.sub.13 -C.sub.14 are trans, cis and trans respectively, the cyclodextrin clathrates thereof and, when R.sup.3 in the group --COOR.sup.3 represents a hydrogen atom, non-toxic salts thereof. These compounds exhibit characteristics of prostaglandin-like activity.
本发明涉及以下结构的化合物:其中A代表以下结构的一个基团:B代表氧或硫原子,R.sup.1和R.sup.2,可以相同也可以不同,每个代表氢或卤素原子,三氟甲基基团,或含有1到4个碳原子的直链或支链烷基或烷氧基基团,R代表以下结构的一个基团--COOR.sup.3,在其中R.sup.3代表氢原子或含有1到12个碳原子的直链或支链烷基基团,或以下结构的一个基团--CH.sub.2 OR.sup.4,在其中R.sup.4代表氢原子或含有2到5个碳原子的烷基羰基基团,且所示的双键在位置C.sub.2 -C.sub.3,C.sub.5 -C.sub.6和C.sub.13 -C.sub.14分别是反式,顺式和反式的,以及它们的环糊精包合物和当在群--COOR.sup.3中R.sup.3代表氢原子时,它们的无毒盐。这些化合物表现出类似前列腺素的活性特征。
