The synthesis and biological activity of (1R,5S,6S)-2-[(3S,5S)-5-substituted pyrrolidin-3-ylthio]-6-[(1R)-1-hydroxyethyl]-1- methylcarbapen-2-em-3-carboxylic acids are described. These compounds exhibit potent antibacterial activity against a wide range of both Gram-positive and Gram-negative bacteria including Pseudomonas aeruginosa. Of these new carbapenems, (1R,5S,6S)-2-[(3S,5S)-5-sulfamoylaminomethyl
(1R,5S,6S)-2-[(3S,5S)-5-取代的吡咯烷-3-基硫基] -6-[((1R)-1-羟乙基] -1-甲基卡宾-2)的合成和生物活性描述了-em-3-羧酸。这些化合物对包括铜绿假单胞菌在内的多种革兰氏阳性和革兰氏阴性细菌均显示出有效的抗菌活性。在这些新的碳青霉烯类化合物中,(1R,5S,6S)-2-[(3S,5S)-5-氨磺酰氨基甲基吡咯烷-3-基硫基] -6-[((1R)-1-羟乙基] -1-甲基碳水化合物apen-2 -em-3-羧基酸(S-4661)显示出最有效和最均衡的活性,因此被选作进一步评估的对象。
