  Synthesis and Structure–Activity Relationships of EGCG Analogues, a Recently Identified Hsp90 Inhibitor

  摘要：

  Epigallocatechin-3-gallate (EGCG), the principal polyphenol isolated from green tea, was recently shown to inhibit Hsp90; however, structure activity relationships for this natural product have not yet been produced. Herein, we report the synthesis and biological evaluation of EGCG analogues to establish structure activity relationships between EGCG and Hsp90. All four rings as well as the linker connecting the C- and the D-rings were systematically investigated, which led to the discovery of compounds that inhibit Hs90 and display improvement in efficacy over EGCG. Antiproliferative activity of all the analogues was determined against MCF-7 and SKBr3 cell lines and Hsp90 inhibitory activity of the four most potent analogues was further evaluated by Western blot analyses and degradation of Hsp90-dependent client proteins. The prenyl-substituted aryl ester of 3,5-dihydroxychroman-3-ol ring system was identified as a novel scaffold that exhibits Hsp90 inhibitory activity.

  Enantio Selective Synthesis of New Phenylpropanoid: Isolated from Walsura trifoliata

  摘要：

  从传统药用植物Walsura trifoliata的叶中分离出一种含有黄酮-3-醇的新苯丙烷类化合物。该化合物的结构是基于光谱证据[2D NMR，HREIMS]和其替代合成确定的。这种天然产物的合成是从廉价且易得的起始材料邻苯三酚二水合物中实现的。关键反应序列包括Grubbs-II RCM反应，Wittig反应和利用AD-mix α的Sharpless二羟基化反应。

  The scope of the Heck arylation of cyclic and acyclic enol ethers with arenediazonium salts was evaluated. Arylation of 2,3-dihydrofuran yielded 2-aryl-2,5-dihydrofurans as the major adducts (>99:1) except when using n-Bu4NHSO4 as additive or 4-NO2PhN2BF4 as arenediazonium salt. 2,3-Dihydropyran provided mixtures of the three possible isomeric Heck adducts. Arylation of n-butylvinylether with arenediazonium bearing electron-donating groups resulted in substituted acetophenones as almost exclusive products in good overall yields, Substituted 4H-chromenes provided 2-aryl-2H-chromenes in moderate yield when applying the Pd(OAc)(2)/2,6-di-t-butyl-4-methylpyridine catalytic system, which were applied in the synthesis of flavonoids.

  A new phenylpropanoid containing flavon-3-ol has been isolated from the leaves of traditional medicinal plant, Walsura trifoliata. The structure of the compound was established on the basis of spectroscopic evidence [2D NMR, HREIMS] and by its alternative synthesis. The synthesis of this natural product was achieved from inexpensive and readily available starting materials of phloroglucinol dihydrate. Key reaction sequence includes Grubbs-II RCM reaction, Wittig reaction and sharpless dihydroxylation using AD-mix α.
