Abstract:

Three alcohol intermediates were synthesized through protection of one side phenolic hydroxyl group, coupling with methyl bromoacetate, and reduction using p-dihydroxybenzene, m-dihydroxybenzene and o-dihydroxybenzene as lead compounds. These three intermediates coupled with three different glycogens to get nine targeting compounds. Similarly, we protected phenolic hydroxyl of 3-(4-hydroxyphenyl)-1-propanol, and then coupled it with three different glycogens to yield three target compounds. The twelve target compounds were characterized by IR, 1H NMR, 13C NMR and HRMS. The study of whitening activity of these conjugates shows that compounds p-HQ-6a, m-HQ-7a, p-HQ-6b, m-HQ-6b, o-HQ-6b, p-HQ-6c, m-HQ-7c, L-3a and L-4b have significant inhibition to tyrosinase, among of them compounds o-HQ-6b and p-HQ-6c against tyrosinase are obviously better than the positive control of α-Abutin.

Key words: arbutin, glycoside, whitening activity
