Abstract

B. C. Revanasiddappa* and E. V. S. Subrahmanyam

A new series of formazans (3a-3I) were synthesized containing the INH moiety, INH upon reaction with substituted aromatic aldehydes yields the Schiff bases (2a-2c). Schiff bases on condensation with different diazonium salts will give formazans. The structure of the final newly compounds were assigned on the basis of IR, 1H NMR and MASS spectral data. All the compounds of this series were evaluated for their In-vitro antibacterial and antifungal activity. Some of the compounds showed promising biological activity.

Formazans; azo compounds; Schiff bases; anti bacterial and anti fungal activity
