Synthesis and antimicrobial activity of some anthranilic acid derivatives

The synthesis of eight derivatives of anthranilic acid is described. Investigation of their antimicrobial activity showed that four of the compounds, viz; anthranilohydrazide, 3,4-dihydro-4-oxo-1,2,3-benzotriazine, triazine-beta-naphthol adduct and N-phenyl anthranilic acid showed significant antibacterial activity. None of the compounds showed any noticeable antifungal effect.
