Abstract

Tyrosinase is known to be a key enzyme in melanogenesis and hyperpigmentation. In this study, a series of thioxo-dihydroquinazolinone compounds were designed and synthesized as tyrosinase inhibitors. Among the investigated compounds, 4m demonstrated the best inhibitory activity with an IC50 value of 15.48 µM compared to kojic acid as a positive control with IC50 value of 9.30 µM. In kinetic evaluation against tyrosinase, 4m depicted a mixed inhibition pattern. Additionally, antioxidant evaluations exhibited moderate to weak potency in 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The detailed interactions and binding mode toward tyrosinase of the most potent derivative were explicated by molecular docking study. Moreover, the computer-aided drug-likeness and pharmacokinetic studies were also carried out. © 2021
