In the present investigation, a series of newly synthesized Schiff bases of few nitrogen containing the above heterocyclic nucleus to evaluate for their possible antioxidant activity.
The title compounds Nl- (substituted benzilidine) — pyridin-3-yl-carbohydrazide (Za-n) were synthesized according to their standard procedures.
The structures of the newly synthesized compounds have been confirmed on the basis of elemental analysis and spectral studies (IR, HKNMR, CUNMR and Mass).
The synthesized compounds were screened for their antioxidant activity by using Nitric oxide (NO) radical scavenging.
The synthesized compounds demonstrated a significant dose dependent antioxidant activity
