  Discovery of Potent, Nonsystemic Apical Sodium-Codependent Bile Acid Transporter Inhibitors (Part 1)

  摘要：

  Elevated plasma levels of low-density lipoprotein (LDL) cholesterol are a major risk factor for atherosclerosis leading to coronary artery disease (CAD), which remains the main cause of mortality in Western society. We believe that by preventing the reabsorption of bile acids, a minimally absorbed apical sodium-codependent bile acid transporter (ASBT) inhibitor would lower the serum cholesterol without the potential systemic side effects of an absorbed drug. A series of novel benzothiepines (3R,3R'-2,3,4,5-tetrahydro-5-aryl-l-benzothiepin-4-ol 1,1-dioxides) were synthesized and tested for their ability to inhibit the apical sodium dependent bile acid transport (ASBT)-mediated uptake of [C-14]taurocholate (TC) in H14 cells. A 3R,4.R,5R13S,4S,5S racemate was found to have greater potency than the other three possible racemates. Addition of electron-donating groups such as a dimethylamino substituent at the 7 position greatly enhanced potency, and incorporation of a long-chain quaternary ammonium substituent on the 5-phenyl ring was useful in minimizing systemic exposure of this locally active ASBT inhibitor while also increasing water solubility and maintaining potency. The reported results describe the synthesis and SAR development of this benzothiepine class of ASBT inhibitors resulting in an 6000-fold improvement in ASBT inhibition with desired minimal systemic exposure of this locally acting drug candidate.

  reactions for amide bond formation have transformed the ability to access synthetic proteins and other bioconjugates through ligation of fragments. In these ligations, amide bond formation is accelerated by transient enforcement of an intramolecular reaction between the carboxyl and the amine termini of two fragments. Building on this principle, we introduce an aldehyde capture ligation that parlays

  酰胺键形成的化学选择性反应改变了通过片段连接获得合成蛋白质和其他生物偶联物的能力。在这些连接中，两个片段的羧基和胺末端之间的分子内反应的瞬时增强加速了酰胺键的形成。基于这一原则，我们引入了一种醛捕获连接，它利用醛和胺的高化学选择性反应性来加强现有技术难以连接的氨基酸残基和肽之间的酰胺键形成。

  A catalytic protocol for synthesis of thioesters from aryl, vinyl, and benzyl bromides as well as benzyl chlorides was developed using only stoichiometric amounts of carbon monoxide, produced from a solid CO precursor inside a two-chamber system. As a catalytic system, the combination of bis(benzonitrile) palladium(II) chloride and Xantphos furnished the highest yields of the desired compounds, along

  使用芳烃，乙烯基和苄基溴化物以及苄基氯来合成硫酯的催化方案仅使用化学计量量的一氧化碳开发，该一氧化碳是由两室系统中的固态CO前驱体产生的。作为催化体系，双（苄腈）氯化钯（II）和Xantphos的组合在120°C的苯甲醚溶液中提供了所需化合物以及弱碱NaOAc的最高收率。为了确保反应中的高化学选择性，催化体系和溶剂的选择被证明是重要的。富电子和缺电子的芳基溴在此反应中均能很好地发挥作用。向反应中加入1当量的碘化钠可改善缺电子的芳基溴化物的化学选择性。硫醇范围包括芳基和烷基硫醇，包括2-巯基二苯甲酮，其中通过硫羰基化和随后的McMurry偶联生成不同取代的苯并噻吩。事实证明，该方法可以适用于13 C引入噻吩环。

  The Michael-aldol product (8) from PhSH-PhCHO-2(5H)-furanone is converted by acids to the tricyclic compound (9), without the intermediacy of the olefin (10). The podophyllotoxin analog (22) was similarly obtained. The all-trans compounds were isomerised by DBU to the cis lactones. Hydroxylated analogs (26) and (33) were produced by reacting 2-(5H)-furanone with appropriate 2-mercaptobenzophenones

  We employ a single catalyst/oxidant system to enable the asymmetric syntheses of indolines, benzodihydrothiophenes, and indanes by C−H insertion of donor/donor carbenes. This methodology enables the rapid construction of densely substituted five‐membered rings that form the core of many drug targets and natural products. Furthermore, oxidation of hydrazones to the corresponding diazo compounds proceeds
