  Synthesis and Chemopreventive Potential of 5-FU/Genistein Hybrids on Colorectal Cancer Cells

  摘要：

  我们合成了一系列 5-FU -染料木素混合物，并通过光谱分析阐明了它们的结构。在人结肠腺癌细胞（SW480 和 SW620）和非恶性细胞系（HaCaT 和 CHO-K1）中评估了这些化合物的化学预防潜力。杂交化合物 4a 对 SW480 和 SW620 细胞具有细胞毒性，IC50 值分别为 62.73 ± 7.26 µM 和 50.58 ± 1.33 µM；化合物 4g 对 SW620 细胞具有细胞毒性，IC50 值为 36.84 ± 0.71 µM。这些化合物的选择性甚至高于单独的染料木素、参考药物（5-FU）以及染料木素和 5-FU 的等摩尔混合物。此外，杂交化合物 4a 和 4g 诱导了时间和浓度依赖性的抗增殖活性，并使细胞周期停滞在 S 期和 G2/M。研究还观察到，杂交种 4a 可诱导 SW620 细胞凋亡，这可能是由 p53 激活后的外显子通路触发的，caspases 3/8 和肿瘤抑制蛋白（Tp53）水平的升高证明了这一点。分子对接研究表明，活性最强的化合物 4a 能与促凋亡的人类 caspases 3/8 和人类 Tp53 有效结合，这反过来又能为该化合物在 SW620 结肠癌细胞系中产生体外细胞毒性反应的生化机制提供有价值的信息。另一方面，分子动力学（MD）研究提供了强有力的证据，证明在 100 ns 全原子 MD 模拟中获得的 caspase-3 与杂交 4a 复合物的构象稳定性。分子力学泊松-玻尔兹曼表面积（MM-PBSA）分析表明，配体与目标蛋白之间的相互作用是稳定的。总之，研究结果表明，在结直肠癌模型中，活性杂交化合物（主要是化合物 4a）可能会通过调节 caspase-3 的活性而发挥作用，使其成为一种可用于未来研究的特殊支架。

  类黄酮氮芥子衍生物的合成及其体外抗肿瘤活性的研究。

  摘要：

  合成了几种新颖的类黄酮氮芥子衍生物，并通过体外MTT分析评估了其对七种人类癌细胞系（HeLa，A549，HepG2，MCF7，SH-SY5Y，PC-3，DU145）的抗增殖活性。所得的IC 50显示大多数化合物对七种细胞系表现出更好的抑制活性。一些化合物的IC50值低于众所周知的美法仑。特别是，化合物8b是抑制HeLa细胞的最有前途的化合物，IC50值为1.43μM。它对这七个细胞系显示出极好的抗肿瘤活性。此外，它可以阻止HeLa在G2 / M期的细胞周期并诱导细胞凋亡。线粒体膜电位的丧失可能是细胞凋亡的介导因子。

  A series of genistein derivatives with carbon spacer-linked alkylbenzylamines were designed, synthesized and tested as multifunctional agents for the treatment of Alzheimer's disease (AD). The results showed that most of these compounds exhibited good acetylcholinesterase (AChE) inhibitory activity, with moderate-to-good anti-oxidative activity. Specifically, compounds 10b, 19d and 254 exhibited significant inhibition of beta-amyloid (A beta) aggregation and exhibited metal chelating properties. In particular, 25d inhibited: self-induced A beta(1-42) aggregation, Cu2+-induced A beta(1-42) aggregation, and human AChE-induced A beta(1-40) aggregation by 35%, 77.8%, and 36.2%, respectively. Moreover, both kinetic analysis of AChE inhibition and the molecular modeling study suggested that 25d binds simultaneously to catalytic active site and peripheral anionic site of AChE. More importantly, compound 25d disassembled the well-structured A beta fibrils generated by Cu2+-induced A beta aggregation by 72.1%. Furthermore, the step-down passive avoidance test showed this compound significantly reversed scopolamine-induced memory deficit in mice. These results suggest that 25d may be a promising multifunctional agent for AD treatment. (C) 2014 Elsevier Masson SAS. All rights reserved.

  AbstractA series of genistein derivatives were synthesized and evaluated as multifunctional anti‐Alzheimer agents. The results showed that these derivatives had significant acetylcholinesterase (AChE) inhibitory activity; compound 5a exhibited the strongest inhibition to AChE with an IC50 value (0.034 μM) much lower than that of rivastigmine (6.53 μM). A Lineweaver–Burk plot and molecular modeling study showed that compound 5a targeted both the catalytic active site and the peripheral anionic site of AChE. These compounds also showed potent peroxy scavenging activity and metal‐chelating ability. The compounds did not show obvious effect on HepG2 and PC12 cell viability at the concentration of 100 μM. Therefore, these genistein derivatives can be utilized as multifunctional agents for the treatment of AD.

  Three series of genistein derivatives with heterocycles were prepared, in which genistein and heterocyclic moieties were separated by 2-carbon, 3-carbon and 4-carbon spacers. Among the 33 compounds we prepared 11 of them (2c and 5a-j) are reported for the first time, while the preparation of 2a,b, 3a-j and 4a-j was reported in our recent paper. All the derivatives were screened for antibacterial (Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas fluorescence) and antifungal (Aspergillus niger, Candida albicans and Trichophyton rubrum) activities by MTT method. Among the compounds tested, 4a, 4e, 4f, 4h, 5e and 5f exhibited good antibacterial activities while 4a also showed notable antifungal activity. Especially, 5f exhibited stronger antibacterial activity against B. subtilis and S. aureus comparable to positive controls. (c) 2007 Elsevier Masson SAS. All rights reserved.
