The present invention relates to 2-penem compounds of the formula
wherein R is lower alkyl, aminoloweralkyl, mono- or diloweralkylaminoloweralkyl, acylaminoloweralkyl, aralkyl, heteroaralkyl, hydroxyloweralkyl, hydroxyaralkyl, carbox- yloweralkyl or alkoxycarbonylloweralkyl; R1 is hydrogen, lower alkyl, aralkyl or a group of the formula: R6 CHOH- with R6 being hydrogen, lower alkyl, aralkyl, heteroaryl, heteroaralkyl, hydroxyaralkyl or aryl; R2 is hydrogen or methyl; and X is cyano, tetrazol-5-yl, -COOR3 or -CONR4R5 wherein R3 is hydrogen, an alkali metal cation, phthalidyl or a pivaloyloxymethyl group; and R. and R5 are independently hydrogen or lower alkyl; with the proviso that when X is -COOR3 both R1 and R2 cannot be hydrogen; to pharmaceutical compositions comprising such compounds and methods for preparing them.
本发明涉及式 2-亚麻烯化合物
其中 R 是低级烷基、氨基低级烷基、单或稀低级烷基氨基低级烷基、酰基氨基低级烷基、芳基、杂芳基、羟基低级烷基、羟基芳基、羧基低级烷基或烷氧基羰基低级烷基; R1 是氢、低级烷基、芳基或式中的基团:R6 CHOH-,其中 R6 为氢、低级烷基、芳基、杂芳基、杂烷基、羟基芳基或芳基;R2 为氢或甲基;X 为氰基、四唑-5-基、-COOR3 或-CONR4R5,其中 R3 为氢、碱金属阳离子、酞酰基或新戊酰氧基甲基;R.和 R5 独立地为氢或低级烷基;但当 X 为-COOR3 时,R1 和 R2 均不能为氢;包含此类化合物的药物组合物及其制备方法。
