  A focused sulfated glycoconjugate Ugi library for probing heparan sulfate-binding angiogenic growth factors

  摘要：

  A library of small molecule heparan sulfate (HS) mimetics was synthesized by employing the Ugi four-component condensation of D-mannopyranoside-derived isocyanides with formaldehyde as the carbonyl component and a selection of carboxylic acids and amines, followed by sulfonation. The library was used to probe the subtle differences surrounding the ionic binding sites of three HS-binding angiogenic growth factors (FGF-1, FGF-2 and VEGF). Each compound features 3 or 4 sulfo groups which serve to anchor the ligand to the HS-binding site of the protein, with a diverse array of functionality in place extending from C-1 or C-6 to probe for adjacent favorable binding interactions. Selectivity of binding to these proteins was clearly observed and supported by molecular docking calculations. (C) 2012 Elsevier Ltd. All rights reserved.

  Evaluation of potential Myt1 kinase inhibitors by TR-FRET based binding assay

  摘要：

  In the human cell cycle, the Myt1 kinase is a crucial regulator of the G2/M transition. Because this membrane-associated kinase is hard to obtain and assay, there is a distinct lack of data so far. Here we report the derivatization of a glycoglycerolipid which was shown previously to be active in a Myt1 activity assay. These compounds were tested in a binding assay together with a set of common kinase inhibitors against a full-length Myt1 expressed in a human cell line. Dasatinib exhibited nanomolar affinity whereas broad coverage inhibitors such as sunitinib and staurosporine derivatives did not show any effect. We also carried out docking studies for the most potent compounds allowing further insights into the inhibitor interaction of this kinase. The glycoglycerolipids showed no significant effects in the binding assay, endorsing the idea of a mechanism of action distant from the active site. (C) 2012 Elsevier Masson SAS.

• New Oligosaccharide Analogues: Non-Glycosidically Linked Thioether-­Bridged Pseudodisaccharides
  作者：Ian Cumpstey

  DOI：10.1055/s-2006-947338

  日期：2006.7

  The synthesis of six disaccharide analogues is reported. The pseudodisaccharides each consist of two monosaccharide residues linked non-glycosidically via a thioether functionality; both C 2 -symmetric and unsymmetrically substituted examples are described. The synthesis was achieved by first introducing an acetate-protected sulfur into partially protected carbohydrates by S N 2 displacement of sulfonate

  报道了六种二糖类似物的合成。每个假双糖由两个单糖残基组成，通过硫醚官能团非糖苷连接；描述了C 2 对称和不对称取代的实例。该合成是通过首先通过硫代乙酸酯取代磺酸酯的 SN 2 将乙酸酯保护的硫引入部分保护的碳水化合物中来实现的。硫的脱乙酰之后用另一种碳水化合物磺酸盐衍生物处理，第二次 SN 2 置换得到假双糖产物。

  Hydrolytically stable non-glycosidically linked tail-to-tail pseudodisaccharides are linked by a single bridging atom remote from the anomeric centre of the constituent monosaccharides. Some such pseudodisaccharides with sulfur or oxygen bridges were found to act as disaccharide mimetics in their binding to the Banana Lectin and to Concanavalin A. A versatile synthetic route to a small library of such

  Non-glycosidically linked disaccharide mimetics with a selenoether functionality linking the two monosaccharide residues have been synthesised.
