  Synthesis and Structure−Activity Relationship of Mannose-Based Peptidomimetics Selectively Blocking Integrin α4β7 Binding to Mucosal Addressin Cell Adhesion Molecule-1

  摘要：

  As part of our ongoing research in the development of alpha4beta7 integrin antagonists, we are interested in peptidomimetics based on a rigid scaffold to allow the display of essential side chains in a suitable binding conformation while eliminating backbone amide bonds and therefore improving pharmacokinetic parameters of the drug. Except for a few examples, peptidomimetics scaffolds have only been moderately successful and often yield molecules that lack the potency of their peptide counterparts. However, we present herein a successful application of using a rigid scaffold. Starting from a mannopyranoside analogue previously discovered in our laboratory as an inhibitor of the alpha4beta1/vascular cell adhesion molecule interaction, a biased library of functionalized carbohydrates was developed. One compound emerged from this library as an active and selective antagonist toward the alpha4beta7/mucosal addressin cell adhesion molecule interaction. Conformational. implications and the relevance of different pharmacophoric patterns will be discussed in order to explain the reverse selectivity and enhanced affinity.

  长期寻求从氧化膦合成季phospho盐的方法：逆反应法†

  摘要：

  季phospho盐（QPS）是一类重要的有机磷化合物，以前只能通过涉及亲核性磷的途径获得。我们报告了利用膦氧化物作为亲电子伴侣和格氏试剂作为亲核试剂实现QPS的相反方法的实现。通过衍生的卤化salts盐的关键中间体来实现该过程。该路线不受动力学慢和许多母体膦的有限供应的困扰，并且以优异的产率制备了多种QPS。

  phosphonium salts R3PR1 X (X = Cl, Br) from phosphine oxides R3PO. The new organic group R1 is introduced via nucleophilic attack on an intermediate halophosphonium salt using a Grignard reagent R1MgX and replaces the traditional phosphine quaternization approach. Consequently, the new method does not suffer from the limited availability of many parent phosphines and is much faster than standard quaternization

  摘要 我们提出了一种新的、潜在广泛适用的 Umpolung 方法，用于从氧化膦 R3PO 合成季鏻盐 R3PR1 X (X = Cl, Br)。新的有机基团 R1 是通过使用格氏试剂 R1MgX 对中间卤代鏻盐进行亲核攻击引入的，并取代了传统的膦季铵化方法。因此，新方法不会受到许多母膦的有限可用性的影响，并且比标准季铵化要快得多。图形概要
