ABSTRACT
Objective To study the inhibitory mechanism of soliquiritigenin on tyrosinase.Methods The inhibition effect and inhibitory kinetics of tyrosinase induced by oliquiritigenin were investigated.The effect of isoliquiritigenin on A375 melanoma cell were preliminarily indicated.Results The inhibitory effect of isoliquiritigenin on monophenolase and diphenolase of tyrosinase was good, IC50 was (11.22 ±0.92) μM and (48.53 ±4.75) μM, isoliquiritigenin was a competitive inhibitor, the value of inhibition constant ( Ki ) was ( 12.14 ±0.54 ) μM.Isoliquiritigenin could inhibit the prolifevation of A375 cell significantly, and the tyrosinase activity and melanin synthesis decreased.Conclusion Isoliquiritigenin as a tyrosinase inhibitor, plays an important role in the regulation of melanin, which provides the theoretical basis for the clinical anti skin cancer.
