  摘要：

  通过结合芳基肉桂酰胺和康维他汀药效基团，在杂交方法的基础上设计了一系列新分子。合成并评估它们的细胞毒性活性，对微管蛋白聚合的抑制作用和凋亡诱导能力。大多数缀合物对某些代表性的人类癌细胞系均表现出显着的细胞毒性活性，其中两个缀合物6i和6p表现出强的细胞毒性，其对人乳腺癌细胞系（MCF-7）的GI50值分别为56nM和31nM。SAR研究表明，肉桂酰胺部分苯环上的3,4-取代有利于增强细胞毒性。此外，除了微管蛋白聚合抑制（IC50为1.97μM和1.之外），这些结合物（6i和6p）还诱导了G2 / M细胞周期阻滞。分别为05μM）。此外，线粒体膜电位，膜联蛋白V-FITC和caspase-9活化试验表明，这些结合物可通过凋亡诱导细胞死亡。对接研究表明，这些结合物在微管蛋白的秋水仙碱结合位点相互作用并结合。

  5-trimethoxystyryl)phenyl]-4-methoxybenzenesulfonamide (9 a) were found to be potent. Similar results were obtained against three human cancer cell lines with IC50 values ranging between 0.04 and 3.0 μm. Studies aimed at elucidating the mechanism of action of these new analogues revealed that they inhibited the in vitro polymerization of tubulin and disorganized the assembly of microtubules in HeLa and MCF-7cancer

  可以通过采用从已知生物活性化合物对特有支架进行支架跳跃的策略，在药物开发中开发出新的疗法。该策略已在药物发现过程中广泛采用。基于结构的对接研究阐明了基本的基本概念，并揭示了磺酰胺基团的相互作用和疏水性相互作用至关重要。在此策略的基础上，合成了60多种合成类似物，并评估了其对60种人类癌细胞系NCI检测的细胞毒性。这些化合物大多数显示出有希望的细胞毒性，GI50值在18至50 nm之间。在这些化合物中，（Z）-N- [2,3-二甲氧基-5-（3,4,5-三甲氧基苯乙烯基）苯基] -4-甲氧基苯磺酰胺（7a）和（Z）-N- [2-羟基- 3-甲氧基-6-（3,4，发现5-三甲氧基苯乙烯基）苯基] -4-甲氧基苯磺酰胺（9a）是有效的。针对三种人类癌细胞系，IC50值介于0.04至3.0μm之间，也获得了相似的结果。旨在阐明这些新类似物作用机理的研究表明，它们抑制了微管蛋白的体外聚合，并破坏了H

  A series of analogs with nitro or serinamide substituents at the C-2'-, C-5'-, or C-C-position of the combretastatin A-4 (CA4) B-ring was synthesized and evaluated for cytotoxic effects against heart endothelioma cells, blood flow reduction to tumors in SCID mice, and as inhibitors of tubulin polymerization. The synthesis of these analogs typically featured a Wittig reaction between a suitably functionalized arylaldehyde and an arylphosphonium salt followed by separation of the resultant F and Z-isomers. several of these nitrogen-modified CA4 derivatives (both amino and nitro) demonstrate significant inhibition of tubulin assembly as well as cytotoxicity and in vivo blood flow reduction. 2'-Aminostilbenoid 7 and 2'-amino-3'-hydroxystilbenoid 29 proved to be the most active in this series. Both compounds, 7 and 29, have the potential for further pro-drug modification and development as vascular disrupting agents for treatment of solid tumor cancers and certain ophthalmological diseases.

  A series of 1,2,3-triazole linked aminocombretastatin conjugates were synthesized and evaluated for cytotoxicity, inhibition of tubulin polymerization and apoptosis inducing ability. Most of the conjugates exhibited significant anticancer activity against some representative human cancer cell lines and two of the conjugates 6d and 7c displayed potent cytotoxicity with IC50 values of 53 nM and 44 nM against A549 human lung cancer respectively, and were comparable to combretastatin A-4 (CA-4). SAR studies revealed that 1-benzyl substituted triazole moiety with an amide linkage at 3-position of B-ring of the combretastatin subunit are more active compared to 2-position. G2/M cell cycle arrest was induced by these conjugates 6d and 7c and the tubulin polymerization assay (IC50 of 1.16 μM and 0.95 μM for 6d and 7c, respectively) as well as immunofluorescence analysis showed that these conjugates effectively inhibit microtubule assembly at both molecular and cellular levels in A549 cells. Colchicine competitive binding assay suggested that these conjugates bind at the colchicine binding site of tubulin as also observed from the docking studies. Further, mitochondrial membrane potential, ROS generation, caspase-3 activation assay, Hoechst staining and DNA fragmentation analysis revealed that these conjugates induce cell death by apoptosis.
