Cefacetrile (INN, also spelled cephacetrile) is a broad-spectrum first generation cephalosporin antibiotic effective in gram-positive and gram-negative bacterial infections. It is a bacteriostatic antibiotic.[1][2] Cefacetrile is marketed under the trade names Celospor, Celtol, and Cristacef,[3] and as Vetimast for the treatment of mammary infections in lactating cows.[2]

Synthesis

Cefacetrile synthesis: NL 6600586 (1966 to Ciba-Geigy).

It was made by reacting 7-ACA (7-aminocephalosporanic acid) with cyanoacetyl chloride in the presence of tributylamine.
