  Design, synthesis and biological study of pinacolyl boronate-substituted stilbenes as novel lipogenic inhibitors

  摘要：

  A pilot library of novel 4,4,5,5-tetramethyl-2-(4-substitutedstyrylphenyl)-1,3,2 dioxaborolane derivatives has been synthesized. 4-(4,4,5,5-Tetramethyl-1,3,2-dioxaboratophenyl)-methyl triphenylphosphonium bromide 3 was treated with various aldehydes in the presence of 3 equiv of (BuONa)-Bu-t in DMF, and stirred at room temperature for 4-6 h to yield the corresponding boron-containing stilbene derivatives in 71-94% yields. Several of them, including BF102 and BF175, have the lipogenesis inhibitory effect by suppressing lipogenic gene expression in mammalian hepatocytes. Further, BF102 also inhibits cholesterol biosynthesis by suppressing HMG-CoA reductase gene expression in hepatocytes. Interestingly, our preliminary in vivo data suggests that BF102 has no significant toxicity in mice at the highest possible dose we can administered. Thus, BF102 is a potential lead for the next generation of lipid-lowering drugs. (C) 2011 Elsevier Ltd. All rights reserved.

  A series of new carbazole‐based N‐heterocyclic carbene (NHC) ligands have been synthesized in a simple and facile synthetic route and subsequently used in a Pd/carbazole‐based NHC catalytic system, which was found to be effective in catalyzing Heck reactions to provide substituted stilbene derivatives in good yields. Several bioactive stilbenes, including pterostilbene, pinosylvin, trimethoxy resveratrol

  一系列新的咔唑基氮杂环卡宾（NHC）配体已通过简单且容易的合成路线进行合成，随后用于基于Pd /咔唑的NHC催化体系中，发现该化合物可有效催化Heck反应，以高收率提供取代的二苯乙烯衍生物。合成了几种具有生物活性的对苯二酚，包括萜烯，松油基乙烯基，三甲氧基白藜芦醇和白藜芦醇，而且三甲氧基白藜芦醇的放大倍数也达到了10 mmol。通过一锅法进行双串联化学选择性Heck反应，然后进行Miyaura硼化，可以扩展合成的应用范围，从而可以一步一步获得合成上有用的二苯乙烯基硼酸酯。相似地，

  A series of novel 4,4,5,5-tetramethyl-2-(4-substitutedstyrylphenyl)-1,3,2 dioxaborolane derivatives has been synthesized. 4-(4,4,5,5-tetramethyl-1,3,2-dioxaboratophenyl)-methyl triphenylphosphonium bromide (4) was treated with 3 equiv of tBuONa, various aldehydes in the presence of DMF, and stirred at room temperature 4-6 h to yield the corresponding boron containing stilbene derivatives 1 a-n in 71 -94% yields. A one-pot protocol transformation has also been developed and used this methodology to synthesize boron containing resveratrol analogues. Simple and clean reactions, high yield of the products are the salient features of this methodology. We used this reaction to synthesize the boron capped polyenes. These boron containing polyene systems are potential intermediate to synthesize conjugated polyene as new material for LCD (Liquid Crystal Display) technology. The biological testing of these compounds is currently underway to identify potential therapeutic for Neurodegenerative diseases. (C) 2015 Elsevier B.V. All rights reserved.
