Design, synthesis, kinetic mechanism and molecular docking studies of novel 1-pentanoyl-3-arylthioureas as inhibitors of mushroom tyrosinase and free radical scavengers

A series of novel 1-pentanoyl-3-arylthioureas was designed as new mushroom tyrosinase inhibitors and free radical scavengers. The title compounds were obtained in excellent yield and characterized by FTIR, 1H NMR, 13C NMR and X-ray crystallography in case of compound (4a). The inhibitory effects on mushroom tyrosinase and DPPH were evaluated and it was observed that 1-Pentanoyl-3-(4-methoxyphenyl) thiourea (4f) showed tyrosinase inhibitory activity (IC50 1.568 ± 0.01 mM) comparable to Kojic acid (IC50 16.051 ± 1.27 mM). Interestingly compound 4f exhibited higher antioxidant potential compared to other derivatives. The docking studies of synthesized 1-Pentanoyl-3-arylthioureas analogues were also carried out against tyrosinase protein (PDBID 2ZMX) to compare the binding affinities with IC50 values. The predicted binding affinities are in good agreement with the IC50 values as compound (4f) showed highest binding affinity (?7.50 kcal/mol) compared to others derivatives. The kinetic mechanism analyzed by Line-weavere Burk plots exhibited that compound (4f) inhibit the enzyme inhibits the tyrosinase non-competitively to form an enzyme inhibitor complex. The inhibition constants Ki calculated from Dixon plots for compound (4f) is 1.10 μM. It was also found from kinetic analysis that derivative 4f irreversible enzyme inhibitor complex. It is proposed on the basis of our investigation that title compound (4f) may serve as lead structure for the design of more potent tyrosinase inhibitors.
