Choi, Inkyu published the artcileIn silico and in vitro insights into tyrosinase inhibitors with a 2-thioxooxazoline-4-one template, SDS of cas: 623-50-7, the main research area is thioxooxazolineone template tyrosinase inhibitor insilico invitro insight; 2-thioxooxazoline-4-one; Anti-melanogenesis; Docking simulation; Kojic acid; Tyrosinase; β-phenyl-α,β-unsaturated carbonyl scaffold.
The β-phenyl-α,β-unsaturated carbonyl (PUSC) scaffold confers tyrosinase inhibitory activity, and in the present study, 16 (Z)-5-(substituted benzylidene)-3-phenyl-2-thioxooxazolidin-4-one analogs containing this scaffold were synthesized. Mushroom tyrosinase inhibitory activities were examined Compound 1c (IC50 = 4.70 ± 0.40 μM) and compound 1j (IC50 = 11.18 ± 0.54 μM) inhibited tyrosinase by 4.9 and 2.1-fold, resp., and did so more potently than kojic acid (IC50 = 23.18 ± 0.11 μM). Kinetic anal. of tyrosinase inhibition revealed that 1c and 1j inhibited tyrosinase competitively. Results of docking simulation with mushroom tyrosinase using four docking programs suggested that 1c and 1j bind more strongly than kojic acid to the active site of tyrosinase and supported kinetic findings that both compounds are competitive inhibitors. The docking results of human tyrosinase homol. model indicated that 1c and 1j can also strongly inhibit human tyrosinase. EZ-cytox assays revealed 1c and 1j were not cytotoxic to B16F10 melanoma cells. The effects of 1c and 1j on cellular tyrosinase activity and melanin production were also investigated in α-MSH- and IBMX-co-stimulated these cells. Both compounds significantly and dose-dependently reduced tyrosinase activity, and at 10 μM were more potent than kojic acid at 20μM. Compounds 1c and 1j also inhibited melanogenesis, which suggested that the inhibitory effects of these compounds on melanin production were mainly attributable to their inhibitions of tyrosinase. These results indicate that compounds 1c and 1j with the PUSC scaffold have potential use as whitening agents for the treatment of hyperpigmentation-associated diseases.
