Synthesis, antioxidant, enzyme inhibition and DNA binding studies of novel N-benzylated derivatives of sulfonamide

• Synthesis of Novel N-benzylated sulphonamides
• Structure elucidation by FTIR, NMR and XRD.
• Biological evaluations including antioxidant, enzyme inhibition, and DNA interaction studies.
• Molecular Docking against Butyrylcholinesterase.

A series of novel N-benzylated derivatives of sulfonamide were synthesized and characterized by FT-IR, NMR and XRD analysis. The synthesized compounds were assayed for their biological potential. The biological studies involved antioxidant, enzyme inhibition, and DNA interaction studies. Antioxidant potential was investigated by Ferric Reducing Antioxidant Power assay (FRAP) and DPPH free radical scavenging method, the capacity of synthesized compounds to inhibit the enzyme's activity was assayed by using the well-known Elman method whereas DNA interaction studies were carried out with the help UV–Vis absorption titration method. Moreover, a direct correlation between enzyme inhibition activity and concentration of the compounds was observed both in experimental and molecular docking studies. DNA interaction studies of the synthesized compounds showed weak interaction.
