1,2,3-Triazolyl Phenylhydrazones as Antioxidant Agents: An Ultrasound Promoted Catalyst-Free Synthesis and Molecular Docking Study

Abstract

An efficient, ultrasound assisted catalyst-free, green protocol has been developed for the synthesis of 1,2,3-triazolyl phenylhydrazone derivatives under environmentally benign condition. The antioxidant activity for all the synthesized derivatives were evaluated in vitro by using 1,1-diphenylpicrylhydrazyl (DPPH) radical scavenging method. The compounds 6a, 6e, 6f, and 6i were shows an excellent antioxidant activity than the standard drug butylated hydroxy toluene with IC₅₀ values in the range 12.03 ± 0.11–14.07 ± 0.31 µg/mL. Molecular docking study was also performed to elaborate their possible interactions with Myeloperoxidase enzyme. Furthermore, in silico ADME properties for all the compounds were also studied.
