Abstract

NEW MATERIAL:A cephalosporin derivative of fomula I (R1 is H, tert. lower alkyloxycarbonyl; R2 is H, OR; R3is acetoxy, carbamoyl-substituted or unsubstituted pyridinium, thiazolylthio, tetrazolylthio), and its salt.
EXAMPLE: 7-[N-(4-tertiary butyloxycarbonyl-1-piperazinocarbonyl)-D-phenylglycyl]- amino-3-acetoxymethyl-Δ3-cephem-4-carboxylic acid.
USE: Antibacterial agent having strong activity against Pseudomonas aeruginosa.
PROCESS: The compound I is prepared by the condensation reaction of a compound II (R4 is tert. lower alkyloxycarbonyl) with 7-aminocephalosporanic acid derivatives III, followed by the eliminating of R4 group if necessary
