Abstract

PURPOSE: Cephalosporins I[X is H or methoxy; A is II, III or IV[R1 is O, S or>NR2(R2 is lower alkyl, lower alkoxycarbonyl or acyl)] ; B is acetoxy or -SR3[R3 is (substituted) thiaziazolyl, triazolyl, tetrazolyl, thiazolyl, oxadiazolyl or oxazolyl]] and their salts, e.g. 4β-(4,5-dihydro-5-imino-1,3,4-thiadiazol-2-yl) thioacetamido-5α-methoxy-3-(1-methyltetrazol-5-yl)thiomethyl-▵3-cephem-4carboxylic acid.
