Penem derivatives represented by the following Formula (I):
wherein Z represents a hydroxyl group or a fluorine atom, R1 represents a substituted or unsubstituted alkyl, alkenyl, aralkyl group, aryl group, heterocyclic, or acyl group, or a hydrogen atom, and R2 represents a hydrogen atom or a carboxyl-protecting group; and pharmacologically acceptable salts thereof are antibacterial agents effective against, inter alia, methicillin-resistant Staphylococcus aureus. The derivatives and salts are novel except when R1 is ethyl and Z is hydroxyl. The analogous compounds in which R2 is a carboxyl-protecting group and any hydroxyl group represented by Z is protected are novel process intermediates.
Penem衍生物由以下公式(I)表示:其中Z代表一个羟基团或氟原子,R1代表一个取代或未取代的烷基,烯基,芳基甲基,芳基,杂环基或酰基,或氢原子,R2代表一个氢原子或羧基保护基;及其药理学上可接受的盐是有效的抗菌剂,可用于治疗耐甲氧西林金黄色葡萄球菌等感染。这些衍生物和盐是新颖的,除非R1是乙基且Z是羟基。其中R2是羧基保护基且Z代表的任何羟基被保护的类似化合物是新颖的工艺中间体。
