Synthesis of 7α methoxy 7 [2 (substituted thio)acetamido]cephalosporin derivatives and their antibacterial activities

10.1248/cpb.24.2629

The research focused on the synthesis and antibacterial activities of 7a-methoxy-7-[2-(substituted thio)acetamido]cephalosporin derivatives. The purpose was to develop more active cephalosporin derivatives by nucleophilic displacement of the halogen atom of 7β-(2-halogenoacetamido)-7-methoxy cephalosporanic acid derivatives with various mercapto compounds. The study concluded that the synthesized compounds, particularly those with a five-membered heterocyclic ring in the acylamido group, exhibited potent antibacterial activities, with compound (6) showing activities comparable to the semi-synthetic antibiotic cefoxitin and superior to cephalothin against gram-negative bacteria. Key chemicals used in the process included cephamycin C, tert-butoxycarbonyl azide, diphenyldiazomethane, chloroacetyl chloride, bis(trimethylsilyl)trifluoroacetamide, and various mercapto compounds for the nucleophilic displacement reaction.
