  Design, synthesis and antimicrobial activity of chiral 2-(substituted-hydroxyl)-3-(benzo[d]oxazol-5-yl)propanoic acid derivatives

  摘要：

  Chiral 2-(substituted-hydroxyl)-3-(benzo[d]oxazol-5-yl)propanoic acid derivatives were synthesized and their antibacterial activities were evaluated against fungus, Gram-negative and Gram-positive bacteria. In general, these compounds showed in vitro activities against all screened Gram-negative and Gram-positive bacteria, but poor MIC values for fungus Candida albicans. Remarkably, the (S)-configuration-substituted phenoxyl side chain on position 2 of propanoic acid exerted excellent antibacterial activity against all screened bacteria. Preliminary structure activity studies revealed that the hydrophobic substitutes, para-tert-butyl (11r), para-phenyl (11s) and para-benzyloxy (11t) on the phenoxyl side chain displayed best activities against all Gram-negative and Gram-positive bacteria with MIC values between 1.56 and 6.25 mu g/mL.

  The first systematic study of catalytic enantioselective 1,2-additions to acrolein is described. Specifically, using allyl alcohol as a tractable, inexpensive acrolein proelectrophile, iridium-catalyzed acrolein allylation is achieved with high levels of regio-, anti-diastereo-, and enantioselectivity. This process delivers 3-hydroxy-1,5-hexadienes, a useful compound class that is otherwise challenging

  描述了丙烯醛催化对映选择性 1,2-加成的首次系统研究。具体而言，使用烯丙醇作为易于处理的、廉价的丙烯醛亲电子试剂，实现了铱催化的丙烯醛烯丙基化，具有高水平的区域选择性、反非对映选择性和对映选择性。该过程产生 3-羟基-1,5-己二烯，这是一种有用的化合物类别，否则很难通过对映选择性催化获得。该方法的两次使用解锁了两栖内酯 R（9 vs 23 步骤，LLS）和两栖内酯 J（9 vs 23 或 26 步骤，LLS）的简明全合成，其制备步骤少于以前可能的一半，并且首次全合成 amphidinolide S（10 步，LLS）。

  A new series of alpha-aryl or alpha-heteroarylphenyl propanoic acid derivatives was synthesized that incorporate acetylene-, ethylene-, propyl-, or nitrogen-derived linkers as a replacement of the commonly used ether moiety that joins the central phenyl ring with the lipophilic tail. The effect of these modi. cations in the binding and activation of PPAR alpha and PPAR gamma was first evaluated in vitro. Compounds possessing suitable profiles were then evaluated in the ob/ob mouse model of type 2 diabetes. The propylene derivative 40 and the propyl derivative 53 demonstrated robust plasma glucose lowering activity in this model. Compound 53 was also evaluated in male Zucker diabetic fatty rats and was found to achieve normalization of glucose, triglycerides, and insulin levels. An X-ray crystal structure of the complex of 53 with the PPAR gamma-ligand-binding domain was obtained and discussed in this report. (c) 2008 Elsevier Ltd. All rights reserved.
