Inhibitory kinetics of novel 2,3-dihydro-1 H -inden-1-one chalcone-like derivatives on mushroom tyrosinase
摘要:
In this study, novel 2,3-dihydro-1H-inden-1-one chalcone-like compounds and their hydroxyl derivatives were synthesized, and their inhibitory effects on mushroom tyrosinase activity were evaluated. Two of the compounds synthesized inhibited the diphenolase activity of tyrosinase in a dose dependent manner and exhibited much higher tyrosinase inhibitory activities (IC50 values of 12.3 mu M and 8.2 mu M, respectively) than the positive control, kojic acid (IC50: 27.5 mu M). Kinetic analysis showed that their inhibition was reversible. Both the novel compounds displayed competitive inhibition with their K-i values of 10.3 mu M and 8.7 mu M, respectively. This study suggests hydroxy substituted 2,3-dihydro-1H-inden-1-one chalcone-like compounds to serve as promising candidates for use as depigmentation agents. (C) 2015 Elsevier Ltd.
