  A novel series of parenteral cephalosporins exhibiting potent activities against both Pseudomonas aeruginosa and other Gram-negative pathogens. Part 2: Synthesis and structure–activity relationships

  摘要：

  A novel series of 7 beta-[2-(2-amino-5-chloro-thiazol-4-yl)-2(Z)-((S)-1-carboxyethoxyimino)acetamido]cephalosporins bearing various pyridinium groups at the C-3' position were synthesized and their in vitro antibacterial activities against Gram-negative pathogens including Pseudomonas aeruginosa and several Gram-positive pathogens were evaluated. Among the cephalosporins prepared, we found that a cephalosporin bearing the 2- amino-1-(3-methylamino-propyl)-1H-imidazo[4,5-b] pyridinium group at the C-3' position (8a) showed potent and well-balanced antibacterial activities against P. aeruginosa and other Gram-negative pathogens including the strains which produce class C beta-lactamase and extended spectrum beta-lactamase (ESBL). Compound 8a also showed efficacious in vivo activity and high stability against AmpC beta-lactamase. These findings indicate that 2-aminoimidazopyridinium having an aminoalkyl group at the 1-position as a C-3' side chain is suitable for cephalosporins bearing an aminochlorothiazolyl moiety and a carboxyethoxyimino moiety on the C-7 side chain.
