Novel inhibitors of Ras protein activation have been found, containing a bicyclic core derived from D-arabinose and benzyl and phenylhydroxylamine moieties. NMR studies (trNOE, saturation-transfer difference, STD) of the binding between these molecules and human p21 h-Ras are reported. A pharmacophore mapping indicates that both the benzyl and the phenylhydroxylamine moieties are essential for protein
已经发现了新的 Ras 蛋白激活抑制剂,其包含衍生自 D-阿拉伯糖和苄基和苯基羟胺部分的双环核心。报告了这些分子与人 p21 h-Ras 之间结合的 NMR 研究(trNOE,饱和转移差异,STD)。药效团映射表明苄基和苯羟胺部分对于蛋白质结合都是必不可少的。合成并测试了缺少其中一组的分子以证实这一假设,并且在体外未观察到与 Ras 的相互作用,也未观察到在哺乳动物细胞中的生物活性。我们的研究导致开发出选择性抑制哺乳动物细胞中 Ras 依赖性细胞生长的分子。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
