  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。

  DMU-212, a methoxylated resveratrol analog, has significant anticancer activity, and selectively targets tumor cells. A library of E-diarylstilbenes structurally related to DMU-212 has been synthesized and evaluated for anticancer activity against a large panel of 45 human cancer cell lines. From this study, DMU-212 (3a) exhibited an average growth inhibitory effect (GI50) of 3.5 M against all the human cancer cell lines in the panel, and was particularly effective against the four cancer cell lines: SNB-75 (CNS), MDA-MB-435 (melanoma), A498 (renal), and MCF7 (breast), with GI50 values of 1.88, 1.04, 0.74 and 1.66 µM, respectively. Also, the 4’-chloro analog of DMU-212, 3d, exhibited 98 and 80 percent growth inhibition against MDA-MB-435 (melanoma) and K-562 (leukemia) cancer cell lines at a concentration of 10 M. Further investigation of DMU-212 and its analogs may provide novel therapeutic avenues for treatment of a variety of human cancers.

  DMU-212，一种甲氧基化的白藜芦醇类似物，具有显著的抗癌活性，并选择性地靶向肿瘤细胞。已经合成了一系列结构上与DMU-212相关的E-二芳烯烃，并评估其对45种人类癌细胞系的抗癌活性。在这项研究中，DMU-212 (3a) 对所有人类癌细胞系的平均生长抑制效果（GI50）为3.5 μM，对四种癌细胞系表现出特别有效的效果：SNB-75（中枢神经系统）、MDA-MB-435（黑色素瘤）、A498（肾脏）和MCF7（乳腺），其GI50值分别为1.88、1.04、0.74和1.66 μM。此外，DMU-212的4'-氯类似物3d在10 μM浓度下对MDA-MB-435（黑色素瘤）和K-562（白血病）癌细胞系表现出98%和80%的生长抑制。对DMU-212及其类似物的进一步研究可能为治疗各种人类癌症提供新颖的治疗途径。

  (Z)-stilbenoid combretastatin A4, have been considered as promising lead compounds for the development of anticancer drugs. The antitumour properties of stilbenoids are known to be modulated by cytochrome P450 enzymes CYP1A1 and CYP1B1, which contribute to extrahepatic phase I xenobiotic and drug metabolism. Thirty-four methyl ether analogues of resveratrol were synthesised, and their anticancer properties were

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

  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.
