Tyrosinase is an enzyme widely distributed in nature, which has multiple functions, especially in the melanin biosynthesis pathway. Despite the few clin. available tyrosinase inhibitors for whitening, a great demand remains for novel compounds with low side effects in terms of potential carcinogenicity and improved clin. efficacy. A natural product, wedelolactone (WEL), with a polyhydroxyl moiety, attracted our attention as a potential tyrosinase inhibitor. Before we studied the biol. activity of the natural product, a synthetic methodol. research was firstly carried to obtain enough raw material. WEL could be obtained efficiently through palladium-catalyzed boronation/coupling reactions and 2,3-dicyano-5,6-dichlorobenzoquinone (DDQ)-involved oxidative deprotection/annulation reactions. Immediately after, the natural product was proven to be an efficient tyrosinase inhibitor. In conclusion, we developed a mild and efficient approach for the preparation of WEL, and the natural product was disclosed to have anti-tyrosinase activity, which could be widely used in multiple fields. This study involved multiple reactions and reactants, such as 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one (cas: 524-12-9Recommanded Product: 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one).
1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one (cas: 524-12-9) belongs to benzofurans derivatives.Benzofuran is one of the most significant oxygen-containing heterocycles consisting of fused benzene and furan ring, which are widely presented in various naturally occurring and synthetically active compounds. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.Recommanded Product: 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one
