A series of 7beta-[2-(2-aminothiazol-4-yl)-2-(Z)-(carboxymethoxyimino)acetamido]cephalosporins bearing a 1-(substituted)-1H-pyrrolo[3,2-b]pyridinium group at C-3' position was synthesized and their in vitro antibacterial activities against Pseudomonas aeruginosa and other Gram-negative pathogens were evaluated. Among the cephalosporins prepared, 7beta-[2-(2-amino-5-chlorothiazol-4yl)-2(Z)-((S)-1-carboxyethoxyimino)acetamido]cephalosporins (42d) showed potent 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). These results imply that both the Cl atom on the C-7 aminothiazole moiety and the alpha-substituent at the iminoether moiety are essential for the stability against beta-lactamase and the potent activity against Gram-negative bacteria including P. aeruginosa.
