Synthesis, Characterization and Biological Activity of Some Novel Formazan Derivatives

摘要

1 -Substituted phenyl-3-substituted phenyl-4-(o-carboxyphenyl) formazans [3a-s] were synthesized by treating azomethines (A_(1-5)) with diazonium salts. Compounds (A_(1-5)) were synthesized by condensing anthranilic acid with various substituted aromatic aldehydes. All the synthesized compounds were characterized by IR,~1H NMR, Mass and elemental analysis and then evaluated for analgesic, antiinflammatory, antibacterial and antifungal activities.
