  Synthesis and evaluation of stilbene and dihydrostilbene derivatives as potential anticancer agents that inhibit tubulin polymerization

  摘要：

  An array of cis-, trans-, and dihydrostilbenes and some N-arylbenzylamines were synthesized and evaluated for their cytotoxicity in the five cancer cell cultures A-549 lung carcinoma, MCF-7 breast carcinoma, HT-29 colon adenocarcinoma, SKMEL-5 melanoma, and MLM melanoma. Several cis-stilbenes, structurally similar to combretastatins, were highly cytotoxic in all five cell lines and these were also found to be active as inhibitors of tubulin polymerization. The most active compounds also inhibited the binding of colchicine to tubulin. The most potent of the new compounds, both as a tubulin polymerization inhibitor and as a cytotoxic agent, was (Z)-1-(4-methoxyphenyl)-2-(3,4,5-trimethoxyphenyl)ethene (5a). This substance was almost as potent as combretastatin A-4 (1a), the most active of the combretastatins, as a tubulin polymerization inhibitor. Compound 5a was found to be approximately 140 times more cytotoxic against HT-29 colon adenocarcinoma cells and about 10 times more cytotoxic against MCF-7 breast carcinoma cells than combretastatin A-4. However, 5a was found to be about 20 times less cytotoxic against A-549 lung carcinoma cells, 30 times less cytotoxic against SKMEL-5 melanoma cells, and 7 times less cytotoxic against MLM melanoma cells than combretastatin A-4. The relative potencies 5a > 8a > 6a for the cis, dihydro, and trans compounds, respectively, as inhibitors of tubulin polymerization are in agreement with the relative potencies previously observed for combretastatin A-4 (1a), dihydrocombretastatin A-4 (1c), and trans-combretastatin A-4 (1b). The relative potencies 5a > 8a > 6a were also reflected in the results of the cytotoxicity assays. Structure-activity relationships of this group of compounds are also discussed.

  Synthesis and Bioactivity of Resveratrol Analogues

  摘要：

  据报道，白藜芦醇能够增强SIRT1的表达，并通过刺激与哺乳动物SIRT1具有高度同源性的Sir2，显著模拟热量限制的效果。设计并合成了系列新型白藜芦醇衍生物，作为新型SIRT1激动剂的候选物质。通过核磁共振(1H NMR)光谱分析对合成的化合物进行了表征，并利用Bioscreen C MBR机器在100 μM/L浓度下检测了这些化合物对酵母亲本菌株BY4743的Sir2激活作用。与白藜芦醇相比，多个化合物表现出良好的Sir2激活活性。同时，还讨论了这些化合物的结构-活性关系与Sir2激活活性的相关性。

  日期：1994.9

  A series of substituted benzylphosphine oxides has been synthesised by reduction of the corresponding (alpha-chlorobenzyl)phosphine oxide, derived from the benzaldehyde and chlorodiphenylphosphine, with either sodium borohydride (DMSO, 60-70 degrees C, 12 h) or tributyltin hydride and AIBN (C6H6. 80 degrees C, 2 h). Reaction of the (alpha-lithiobenzyl)phosphine oxide with aldehydes gave exclusively E-alkenes.

  日期：2003.9

  Selective removal of the 4-methoxy group of 3,4,5-trimethoxystilbenes was performed under electron transfer conditions from Na metal in THF. Careful control of reaction conditions and quenching procedure allowed the synthesis of either (E)-3,5-dimethoxystilbenes or 3,5-dimethoxybibenzyls. (C) 2003 Elsevier Ltd. All rights reserved.
