Synthesis and in vitro antibacterial activities of 3-thiazol-4-yl-1-carba-1-dethiacephalosporins

The synthesis and microbiological evaluation of a new series of 3-thiazol-4-yl-carba-1-dethiacephalosporins is described. Structure activity relationship was achieved by changing substitution at the 2-position of the thiazole moiety. The result was a mark
