Synthesis, characterization and antibacterial and antifungal evaluation of some para-quinone derivatives.

Some novel Pyrrolo [2,3-f] Indole-3,7-Dicarbonitrile derivatives (1-5) were synthesized using chloranil, malononitrile and anilines. The structures of the newly synthesized compounds were characterized by elemental analysis, FT-IR, (1)H- and (13)C-NMR and mass spectroscopy. These compounds were screened for in vitro antibacterial and antifungal activities against some human pathogenic micro-organisms by employing the disc diffusion technique. Some of the compounds showed moderate to good biological activities when compared with standard drugs. © Georg Thieme Verlag KG Stuttgart · New York.
