preparation of diverse N‐substituted muramyl dipeptides (N‐substituted MDPs) from different protected monosaccharides is described. The synthetic MDPs include N‐acetyl MDP and N‐glycolyl MDP, known NOD2 ligands, and this methodology allows for structural variation at six positions, including the muramic acid, peptide, and N‐substituted moieties. The capacity of these molecules to activate human NOD2 in the
描述了一种灵活的合成策略,该策略可从不同的受保护单糖制备各种N-取代的戊二酰二肽(N-取代的MDP)。合成的MDP包括已知的NOD2配体N-乙酰基MDP和N-甘氨酰基MDP,这种方法允许在六个位置上进行结构变异,包括山mic酸,肽和N-取代的部分。还研究了这些分子在先天免疫应答中激活人NOD2的能力。结果发现,在N-甘氨酰MDP的C 1位置添加甲基显着增强了NOD2的刺激活性。
