摘要:
7-(N-(substituted-imidoyl)aminoacetamido)cephalosporanic acids and their salts and the corresponding betaines and desacetoxy derivatives are valuable as antibacterial agents, nutritional supplements in animal feeds, therapeutic agents in poultry and animals, including man, and are especially useful in the treatment of infectious diseases caused by Gram-positive and Gram-negative bacteria. 7-(N(Phenylacetimidoyl)aminoacetamido)cephalosporanic acid, a preferred embodiment of the invention, is prepared for example, by Raney nickel hydrogenation (50 p.s.i., R.T.) of an aqueous solution of sodium 7-(3-benzyl-1,2,4-oxadiazole-5-one-4acetamido)cephalosporanate which is prepared in turn by reaction of 7-aminocephalosporanic acid with 3-benzyl-1,2,4-oxadiazole-5one-4-acetyl chloride.
