  CP6679, a new injectable cephalosporin. Part1: Synthesis and structure–activity relationships

  摘要：

  A series of cephalosporins bearing a 5,5-fused ring system, an (imidazo/[5,1 -b]thiazolium-6-yl)methyl group, at the C-3 position were synthesized and evaluated for in vitro antibacterial activities. CP6679 (Is) and its analogues showed potent antibacterial activities against Gram-positive and Gram-negative bacteria, including Pseudomonas aeruginosa. They were also highly active against methicillin-resistant Staphylococcus aureus (MRSA). CP6679 (Is) showed more potent antibacterial activity than ceftazidime (CAZ) or cefpirome (CPR) against Pseudomonas aeruginosa and MRSA. (C) 2000 Elsevier Science Ltd. All rights reserved.
