摘要

The synthesis and in vitro antibacterial activity of 7β-[(Z)-2-(2-aminothiazol-4-yl)-2- methoxyiminoacetamido] cephalosporins bearing N-mono or dialkyl and carbamoyl aminopyrazolium, and five-or six-membered rings fused to the 3-aminopyrazolium methyl groups at the 3-position, are described. Aminopyrazolium methyl cephalosporins (23e, f, i), with fused saturated and unsaturated rings were especially effective against ...
