Abstract
Certain 7-acylamido-3-(2-carboxyalkyl-2,3-dihydro-s-triazolo[4,3-b]pyridazin-3-on- 6-ylthiomethyl)-3-cephem-4-carboxylic acids and their salts and easily hydrolyzed esters of the 4-carboxyl group were synthesized and found to be potent antibacterial agents which exhibited good aqueous solubility. A preferred embodiment was 7-[o-(methylaminomethyl)phenylacetamido]-3-(2-carboxyalkyl-2,3-dihydro-s-t riazolo[4,3-b]pyridazin-3-on-6-ylthiomethyl)-3-cephem-4-carboxylic acid.
