• Cephalosporanic acid derivatives including 1,3-thiazol(idinon)e or piperazine moiety have been synthesized.
• Most of the synthesized compounds display antimicrobial activity.
• One compound have been found to possess antiurease activity.
The treatment of 7-ACA with 4-substituted benzensulfonyl chlorides afforded the compounds containing 4-nitro/aminophenyl sulfonylamino moiety in the cephalosporanic acid skeleton (2, 4). The synthesis of the cephalosporanic acid derivatives containing 1,3-thiazole or 5-oxo-1,3-thiazolidine nucleus and sulfonamide function (8a, 8b, 10) was performed starting from 7-ACA by several steps. The reaction of 7-ACA with [4-(2-fluoro-4-nitrophenyl)piperazin-1-yl]acetyl chloride afforded the corresponding 7-{[4-(2-fluoro-4-nitrophenyl)piperazin-1-yl]acetyl}amino derivative (13).The synthesized compounds were screened for their antimicrobial and antiurease activities. Some of them were found to possess good–moderate antimicrobial activity against the test microorganisms. Compound 5d was observed to have moderate anti-urease activity.
Synthesis and biological activities of some cephalosporanic acid derivatives including 1,3-thiazol(idinon)e or piperazine ring were described.Figure optionsDownload as PowerPoint slide
