synthesis of novel 1beta-methylcarbapenems 1a,b having sodium 5-(3- and 5-carboxylic acid)isoxazoloethenyl moieties at C-5 position of pyrrolidine ring and their biological evaluation are described. Both compounds showed potent and well-balanced antibacterial activity as well as high stability to DHP-I. The selected sodium 3-carboxylic acid derivative 1a possessed excellent DHP-I stability and advanced pharmacokinetic
描述了在吡咯烷环的C-5位上具有5-(3-和5-羧酸)异恶唑基乙烯基部分的新型1beta-甲基碳烯化合物1a,b的合成及其生物学评估。两种化合物均显示出有效且均衡的抗菌活性以及对DHP-1的高稳定性。所选择的3-羧酸钠衍生物1a与2和美罗培南相比具有出色的DHP-1稳定性和先进的药代动力学参数。
