A simple method for the synthesis of a sugar furanoid trans vicinal diacid and its incorporation into the N-terminal tetrapeptide sequence (H-Phe-Trp-Lys-Thr-OH) to get glycopeptide 8 has been described. 2D NMR and MD simulation studies of 8 clearly show that the sugar diacid adopts a γ-turn conformation towards the N-terminus.
一种简单的合成糖呋喃类反式二邻苯二甲酸二酸并将其掺入N端四肽序列的简单方法(H-苯丙氨酸-色氨酸-赖氨酸-Thr-OH)已经获得了糖肽8。2D NMR和MD的模拟研究8清楚地表明,糖二酸采用朝向所述N-末端的γ-转构象。
