  摘要：

  对47种合成的姜黄素样二芳基戊烷类类似物进行了抗黑色素生成筛选，结果显示其中一些对B16黑色素瘤细胞的黑色素生成具有强抑制作用。这些作用主要被认为是通过抑制酪氨酸酶活性、抑制酪氨酸酶表达和降解黑色素色素实现的。还讨论了那些抑制黑色素生成和酪氨酸酶活性的姜黄素样二芳基戊烷类类似物的结构-活性关系。在测试的化合物中，（2E,6E）-2,6-双（2,5-二甲氧基苄叉）环己酮显示了最强的抗黑色素生成效果，其机制被认为是在B16黑色素瘤细胞中降解黑色素色素，既不影响酪氨酸酶活性也不影响酪氨酸酶表达。

  Sixty-one curcumin-related compounds were synthesized and evaluated for their anticancer activity toward cultured prostate cancer PC-3 cells, pancreas cancer Panc-1 cells and colon cancer HT-29 cells. Inhibitory effects of these compounds on the growth of PC-3. Panc-1 and HT-29 cells were determined by the MTT assay. Compounds E10, F10, FN1 and FN2 exhibited exceptionally potent inhibitory effects on the growth of cultured PC-3, Panc-1 and HT-29 cells. The IC50 for these compounds was lower than 1 mu M in all three cell lines. E10 was 72-, 46- and 117-fold more active than curcumin for inhibiting the growth of PC-3, Panc-1 and HT-29 cells, respectively. F10 was 69-, 34- and 72-fold more active than curcumin for inhibiting the growth of PC-3, Panc-1 and HT-29 cells, respectively. FN1 and FN2 had about the same inhibitory effect as E10 and F10 toward Panc-1 cells but were less active than E10 and F10 toward PC-3 and HT-29 cells. The active compounds were potent stimulators of apoptosis. The present study indicates that E10, F10, FN1 and FN2 may have useful anticancer activity. (C) 2012 Elsevier Masson SAS.
