The present invention provides compounds of the general formula: ##STR1## wherein E is an alkylene or alkenylene radical containing 2 carbon atoms, R.sup.1 is a cycloaliphatic hydrocarbon radical containing 5 to 12 carbon atoms, which is optionally substituted by up to 4 lower alkyl radicals, as well as halogen atoms, and can optionally be mono- or polyunsaturated, R.sup.2 and R.sup.3, which can be the same or different, are further cycloaliphatic hydrocarbon radicals containing 3 to 7 carbon atoms, hydrogen or halogen atoms, trifluoromethyl radicals or alkyl or alkoxy radicals containing up to 7 carbon atoms which can optionally also be substituted with methyl radicals, X is hydroxyl, Y is a residue of an alcohol or a residue of an amine or the group OZ, Z is hydrogen, an alkali metal or ammonium ion or X and Y taken together are --O--. Thus, these compounds are lactones or hydroxy acids of the formulae: ##STR2## wherein E, R.sup.1, R.sup.2 and R.sup.3 are as stated above, and Z is a hydrogen atom, and alkali metal ion or an ammonium ion; the esters and amides of the free carboxylic acids and the stereoisomeric forms thereof. The present invention also provides processes for the preparation of these compounds and pharmaceutical compositions containing them.
本发明提供了一般式为:##STR1##其中E是含有2个碳原子的烷基或烯基基团,R.sup.1是含有5到12个碳原子的环烷烃基团,可选地被多达4个低烷基基团和卤素原子取代,也可以是单烯或多烯的,R.sup.2和R.sup.3可以相同或不同,是进一步含有3到7个碳原子、氢或卤素原子、三氟甲基基团或含有多达7个碳原子的烷基或烷氧基基团,也可以用甲基基团取代,X是羟基,Y是醇的残基或胺的残基或OZ基团,Z是氢、碱金属或铵离子,或X和Y一起是--O--。因此,这些化合物是式为:##STR2##其中E、R.sup.1、R.sup.2和R.sup.3如上所述,Z是氢原子、碱金属离子或铵离子;自由羧酸的酯和酰胺及其立体异构体。本发明还提供了制备这些化合物的方法和含有它们的药物组合物。
