  The design, synthesis, and anti-tumor mechanism study of N-phosphoryl amino acid modified resveratrol analogues

  摘要：

  A novel series of trans-N-phosphoryl amino acid modified resveratrol analogues were synthesized and evaluated in vitro for their cytotoxic effects against CNE-1 and CNE-2 cell lines. These analogues showed good anti-proliferative activity, among which 8d, 8e, 8j, and 9d displayed much stronger inhibition effect than resveratrol and 8d showed the most potent activity with IC(50) value at 3.45 +/- 0.82 mu M. The antitumor effects of 8d, 8e, 8j, and 9d were due to the induction of apoptosis, confirmed by the DNA fragmentation and flow cytometry analysis using PI (propidium iodide) staining and Annexin-V-FITC/PI staining assay. The PI staining assay also showed that 8d, 8e, 8j, and 9d caused cell cycles arrest at G(0)-G(1) phase which finally led to cell apoptosis. Further mechanism study on compound 8d against CNE-2 cells has shown the PARP cleavage, which is a hallmark of caspase-3 activation, as well as the activation of caspase-9, and the intracellular ROS generation. These results all suggest that 8d induced a mitochondrial-dependent apoptosis pathway. (c) 2008 Elsevier Ltd. All rights reserved.

  发现用于治疗实体癌的 STAT3 和组蛋白脱乙酰酶 (HDAC) 双通路抑制剂

  摘要：

  如今，由于肿瘤发生背后的复杂机制，通过药物组合同时抑制多个靶点是一种重要的抗癌策略。最近的研究表明，组蛋白去乙酰化酶 (HDAC) 的抑制将导致乳腺癌中臭名昭著的癌症相关药物靶标、信号转导和转录激活因子 3 (STAT3) 的补偿激活，这可能会限制抗-HDAC抑制剂在实体瘤中的增殖作用。通过将HDAC抑制剂SAHA（伏立诺他）的药效团并入STAT3抑制剂紫檀芪中，合成了一系列具有双靶点抑制活性的有效紫檀芪异羟肟酸衍生物。一种极好的异羟肟酸酯衍生物，化合物14，抑制 STAT3（K D = 33 nM) 和 HDAC (IC 50 = 23.15 nM)在体外具有强大的效力。化合物14在体内和体外也显示出有效的抗增殖能力。我们的研究为进一步探索提供了第一个 STAT3 和 HDAC 双靶点抑制剂。

  Studies have shown that the abnormal activation of the NLRP3 inflammasome is involved in a variety of inflammatory-based diseases. In this study, a high content screening model targeting the activation of inflammasome was first established and pterostilbene was discovered as the active scaffold. Based on this finding, total of 50 pterostilbene derivatives were then designed and synthesized. Among them

  A new type of three-component reaction of air-stable isochromenylium tetrafluoroborates with electron-rich stilbenes in acetonitrile has been developed under catalyst-free conditions in this work. This cascade multibond-formation reaction is initiated by an intermolecular oxa [4 + 2]-cycloaddition, relayed with a nucleophilic addition of acetonitrile, and terminated by an intramolecular Friedel–Crafts

• Novel resveratrol derivatives have diverse effects on the survival, proliferation and senescence of primary human fibroblasts

  Resveratrol alters the cytokinetics of mammalian cell populations in a dose dependent manner. Concentrations above 25-50 mu M typically trigger growth arrest, senescence and/or apoptosis in multiple different cell types. In contrast, concentrations below 10 mu M enhance the growth of log phase cell cultures and can rescue senescence in multiple strains of human fibroblasts. To better understand the structural features that regulate these effects, a panel of 24 structurally-related resveralogues were synthesised and evaluated for their capacity to activate SIRT1, as determined by an ex-vivo SIRT1 assay, their toxicity, as measured by lactate dehydrogenase release, and their effects on replicative senescence in MRC5 human fibroblasts as measured by their effects on Ki67 immunoreactivity and senescence-associated beta galactosidase activity. Minor modifications to the parent stilbene, resveratrol, significantly alter the biological activities of the molecules. Replacement of the 3,5-dihydroxy substituents with 3,5-dimethoxy groups significantly enhances SIRT1 activity, and reduces toxicity. Minimising other strong conjugative effects also reduces toxicity, but negatively impacts SIRT1 activation. At 100 mu M many of the compounds, including resveratrol, induce senescence in primary MRC5 cells in culture. Modifications that reduce or remove this effect match those that reduce toxicity leading to a correlation between reduction in labelling index and increase in LDH release. At 10 mu M, the majority of our compounds significantly enhance the growth fraction of log phase cultures of MRC5 cells, consistent with the rescue of a subpopulation of cells within the culture from senescence. SIRT1 activation is not required for rescue to occur but enhances the size of the effect.
