The synthesis and biological activity of (1R,5S,6S)-2-[(3S,5S)-5-substituted pyrrolidin-3-ylthio]-6-[(R)-1-hydroxyethyl]-1-methyl-1-ca rbapen-2-em-3- carboxylic acid, in which lactams and cyclic amines are introduced as substituents, are described. They showed potent antibacterial activity against Gram-positive and Gram-negative bacteria including P. aeruginosa. Among them, BO-2502A (4h-1) was selected
(1R,5S,6S)-2-[(3S,5S)-5-取代的吡咯烷-3-基硫基] -6-[[(R)-1-羟乙基] -1-甲基-1)的合成和生物活性描述了其中引入内酰胺和环状胺作为取代基的-ca rbapen-2-em-3-羧酸。他们显示出对革兰氏阳性和革兰氏阴性细菌(包括铜绿假单胞菌)的有效抗菌活性。其中,选择了BO-2502A(4h-1)进行进一步评估。
