Abstract:
The present study envisioned some antioxidant candidates having 1,2,3,4-tetrahydro-9H-pyrido[3,4-b]indole (TRY), 3-(2-bromoethyl)indole (BEI) and 7-azindole (AI) nucleus. Derivatives of these indole molecules were synthesized and their scavenging activity for reactive oxygen species (ROS) investigated by 2,2-diphenyl-1picrylhydrazyl (DPPH) radical scavenging assay. T3, T42 exhibited significant radical scavenging potential which is comparable to ascorbic acid (standard), while T36 appeared as most potent antioxidant by displaying better scavenging activity than standard molecule. Molecular docking study revealed good binding score and interactions of T36 with target human antioxidant enzyme (PDB code: 3MNG) validating the results of biological activity.
