Isoprenoid-substituted flavonoids were isolated from the wood of Artocarpus heterophyllus by means of activity-guided fractionation. Artocarpin (1), cudraflavone C (2), 6-prenylapigenin (3), kuwanon C (4), norartocarpin (5) and albanin A (6) inhibited melanin biosynthesis in B16 melanoma cells without inhibiting tyrosinase. A structure-activity investigation indicated that the presence of the isoprenoid-substituted moiety enhanced the inhibitory activity on melanin production in B16 melanoma cells.
通过活性导向分级分离法从菠萝蜜木材中分离出类异戊二烯取代的黄酮类化合物。菠萝蛋白酶（1）、柘树黄酮C（2）、6-异戊烯基芹菜素（3）、库瓦诺酮C（4）、去甲菠萝蛋白酶（5）和阿尔巴宁A（6）在不抑制酪氨酸酶的情况下抑制B16黑色素瘤细胞中的黑色素生物合成。结构-活性研究表明，类异戊二烯取代部分的存在增强了对B16黑色素瘤细胞中黑色素生成的抑制活性。
