Abstract

NEW MATERIAL:The compound of formula I [R<1> is H or (protected) amino; R<2> is H or (substituted) lower alkyl; R<3> is H or group substituted at 3-position of cephalosporins; R<4> is CO2H, CO or CO2R<5> (R<5> is salt-forming cation or carboxyl-protecting group)] and its salt. EXAMPLE:7-[2-(2-Aminothiazol-4-yl)-4-methoxyimino-2-butenamido]-3-(1- methyltetrazol-5-yl)thiomethyl-3-cephem-4-carboxylic acid sodium salt (Z)-isomer. USE:An antibacterial agent against Gram-positive bacteria and Gram-negative bacteria. PREPARATION:The compound of formula I is produced by reacting a compound of formula II with a compound of formula III. The compound of formula III is a novel substance which can be produced by using the compound of formula IV as a starting substance.
