Abstrakt: The synthesis and in vitro activity of 7-vinylenethioacetamido cephalosporins with a tetrazolo-pyridazine at the 3-position are described. These cephalosporins showed good activity against Gram-positive and Gram-negative bacteria. 7-[(Z)-beta-carboxyvinylenethio-acetamido]-3-[(tetrazolo[1,5-b]pyridazin-8- amino-6-yl)-thiomethyl]-3-cephem-4-carboxylic acid (K 13176, 21) was significantly more active in vitro and in vivo than cefazolin against Gram-negative bacteria.
