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

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. </p
