  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。

  Curcumin is a multifunctional natural product with regulatory effects on inflammation. However, a major limitation for the application of curcumin is its poor bioavailability. We previously demonstrated that the mono-carbonyl analogues of curcumin possessed improved pharmacokinetic profiles. In this study, 33 novel mono-carbonyl analogues of curcumin were synthesized and their inhibition against TNF-alpha and IL-6 release was evaluated in LPS-stimulated RAW 264.7 macrophages. Based on the screening data, quantitative structure activity relationship was conducted, indicating that electron-withdrawing groups in benzene ring are favourable to anti-inflammatory activities of B-class compounds. Furthermore, compounds AN1 and 1382 demonstrated anti-inflammatory abilities in a dose-dependent manner. These raise the possibility that these compounds might serve as potential agents for the treatment of inflammatory diseases. (C) 2010 Elsevier Masson SAS. All rights reserved.
