    摘要:
    合成了多种非天然胆汁酸衍生物 (9a-9f) 并用于检查海七鳃鳗 (Petromyzon marinus) 嗅觉系统检测这些化合物的特异性。这些化合物是硫酸岩藻醇 (PS, 1) 的类似物,是海七鳃鳗迁移信息素的一种成分。C5 的立体化学构型(即 5alpha 与 5beta)以及胆汁酸衍生的类固醇骨架的氧化程度和位点(羟基化或酮化)通过使用嗅觉图记录筛选嗅觉活性的化合物来评估。5beta-Petromyzonol 硫酸盐 (9a) 在亚纳摩尔浓度下引起相当大的嗅觉反应。此外,含氧量较低的系统(即 9b-9e)会引起嗅觉反应,尽管效力较低。还检查了海七鳃鳗性信息素模拟物 9f(5beta-3-ketopetromyzonol 硫酸盐),发现其产生的嗅觉反应要低得多。用 9a 和 PS (1) 进行的混合研究表明刺激是通过类似的激活模式发生的,这表明在海七鳃鳗嗅觉中识别同种异体构型(即 5a

    Investigation on bile acid receptor regulators. Discovery of cholanoic acid derivatives with dual G-protein coupled bile acid receptor 1 (GPBAR1) antagonistic and farnesoid X receptor (FXR) modulatory activity
    摘要:
    Bile acids, the end products of cholesterol metabolism, activate multiple mechanisms through the interaction with membrane G-protein coupled receptors including the bile acid receptor GPBAR1 and nuclear receptors such as the bile acid sensor, farnesoid X receptor (FXR). Even if dual FXR/GPBAR1 agonists are largely considered a novel opportunity in the treatment of several liver and metabolic diseases, selective targeting of one of these receptors represents an attractive therapeutic approach for a wide range of disorders in which dual modulation is associated to severe side effects. In the present study we have investigated around the structure of LCA generating a small library of cholane derivatives, endowed with dual FXR agonism/GPBAR1 antagonism. To the best of our knowledge, this is the first report of bile acid derivatives able to antagonize GPBAR1. (C) 2015 Elsevier Inc. All rights reserved.

  • Tris(3,6-dioxaheptyl)amine: A superior complexing agent for dissolving metal reactions
    作者:Ajay K. Bose、Pietro Mangiaracina
    DOI:10.1016/s0040-4039(00)95452-2
    日期:1987.1
    Commercially available tris(3,6-dioxaheptyl)amine (TDA-1) is an effective phase transfer catalyst for reactions with sodium-potassium alloy in tetrahydrofuran. Deoxygenation of acetates, dehalogenation, and hydrolysis of tosylates and mesylates proceed in high yield. The use of a deuterated alcohol during deoxygenation reactions leads to site-specific deuteration.

    defunctionalization of sp3 C–heteroatom and sp3 C–C bonds with triplet ketone catalysts and bipyridine additives is disclosed. This protocol is characterized by its broad scope without recourse to transition metal catalysts or stoichiometric exogeneous reductants, thus offering a complementary technique for activating σ sp3 C–C(heteroatom) bonds.
