7beta-(5-Aryl-2H-tetrazol-2-yl)acetamidocephalosporanic acid (23~26) and 7beta-(5-Aryl-4-phenyl-4H-1,2,4-triazol-3-yl)thioacetamidocephalosporanic acid were synthesized by condensation of 5-Aryl-2H-tetrazol-2-acetyl choloride(17~20) and 5-Aryl-4-phenyl-4H-1,2,4-triazol-3-thioacetyl chloride(22~24) with 7-Aminocephalosporanic acid (7-ACA), respectively. These seven compounds were tested in vitro antimicrobial activity. These exhibited good antimicrobial activity against Gram-positive bacteria whereas most compounds showed decreased antimicrobial activity against Gram-negative bacteria.
