Synthesis of new indazole derivatives as potential antioxidant agents

New indazole derivatives were synthesized by reacting hydrazine hydrate and its derivatives with cyclohexenone derivatives, which in turn prepared from respective chalcones. The chemical structure of newly synthesized compounds was well characterized by using 1H NMR, 13C NMR, IR and mass spectral data. All the synthesized products were screened for their antioxidant properties. All indazole derivatives exhibited noticeable DPPH radical scavenging activity, reducing power capacity and total antioxidant capacity in comparison with the respective standards.
