  Discovery of small molecules that inhibit melanogenesis via regulation of tyrosinase expression

  摘要：

  5,6,7,8-Tetrahydro-4H-cyclohepta[d]isoxazole derivatives were synthesized and evaluated as a novel class of inhibitors for alpha-melanocyte-stimulating hormone (alpha-MSH) induced melanogenesis in a mouse melanoma B16F10 cell line. Compound 8e (IC50 = 0.67 mu M), 8h (IC50 = 1.01 mu M) and 9b (IC50 = 0.99 mu M) exhibited a potent inhibitory activity approximately 85- to 126-fold greater than kojic acid, a well-known potent inhibitor. A biochemical study indicates that the activity of this series should be displayed via down-regulation of the expression of tyrosinase. (C) 2012 Elsevier Ltd. All rights reserved.
