Synthesis, molecular docking and in vitro anti-bacterial activity of formazan derivatives

Abstract

A new series of Formazan derivatives (F1-10) was synthesized by the reaction of equimolar concentrations of Schiff bases (SB1-10) and Diazonium salts. FT-IR, 1H-NMR and Mass spectral data established the structures of the newly synthesized compounds. In-silico analysis was carried out using Schrodinger suite device and docked to the binding site of Human Poly(ADP-ribose) Polymerase (PDB ID: 3V2B). The highest affinity is demonstrated by compound F2 having a binding energy of -3.158 kcal/mol. All the new compounds were screened for antibacterial potency. Some of the synthesized compounds F4, F9 displayed good antibacterial activity against all the bacterial organisms when compared to the standard.
