Synthesis, Antitumor Evaluation, and Apoptosis-Inducing Activity of Hydroxylated (E)-Stilbenes
摘要:
The parallel solution-phase synthesis of a series of 30 monohydroxylated (E)-stilbene analogues is described. In vitro screening revealed low micromolar activity (GI(50)) against the MDA MB 468 breast cancer cell line. Activity in MDA MB 468 cells correlated with the ability to induce apoptosis following drug treatment by the most potent agents in the series, e.g., 5dy and 5jy, an observation further reinforced by AnnexinV-FITC analysis and fluorescence microscopy.
在本文中,作者报告了 1-吡啶基-2-芳基乙烯、1-呋喃基-2-芳基乙烯、1,2-二苯基丙烯和取代的肉桂基苯胺作为类二苯乙烯的模型化合物,以研究主导取代基推挽效应的因素通过使用桥键碳原子的核磁共振化学位移。证明了最大推挽效应并不总是在 D-π-A 化合物中的强给电子 D 和强电子接受 A 基团之间。D-π-A化合物中取代基推挽作用的作用方式主要由其分子母体结构决定。组的场/感应效应和共轭效应对推挽效应的贡献是不相等的。当 D-π-A 母体分子在一个平面上时,组的场/感应效应对推挽效应的影响大于或接近其共轭效应的影响。虽然母体分子是空间扭曲的,但推挽效应主要取决于基团的共轭效应。本文的结果可以为我们提供关于取代基推拉效应的新见解。

bindings and Aβ plaque imaging. Among these molecules, compound 42 meets two critical requirements for imaging agent; high fluorescence responsiveness and strong binding affinity. This compound showed more than 25-fold increase with the dissociation constant of 1.13 ± 0.37 μM. In AD mouse brain tissue, 42 selectively stained Aβ plaque, more specifically peripheral regions of Aβ plaque. This finding demonstrated
Idiopathic pulmonaryfibrosis (IPF) is a chronic progressive lung disease with a typical survival time between three to five years. Two drugs, pirfenidone and nintedanib have been approved for the treatment of IPF, but they have limited efficacy. Thus, the development of new drugs to treat IPF is an urgent medical need. In this paper we report the discovery of a series of orally active pyrimidin-4(3H)-one
