Synthesis and Antiinflammatory Activity of N-Aryl Anthranilic Acid and its Derivatives

摘要

N-aryl anthranilic acid and its derivatives (3a-f) have been synthesized via Ullmann condensation of o-chloro benzoic acid with various substituted anilines (2a-f) in the presence of cupric oxide and anhydrous potassium carbonate. All the synthesized compounds (3a-f) were characterized by mp, TLC, UV, IR, H NMR and mass spectral analysis. All the synthesized compounds (3a-f) were screened for their antiinflammatory activity by carrageenan induced rat paw edema method. All the synthesized compounds (3a-f) showed significant antiinflammatory activity. Compounds 3a and 3c were found to be the most potent compounds.
