摘要

A flexible synthetic strategy toward the 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 innate immune response was also investigated. It was found that addition of the methyl group at the C1 position of N-glycolyl MDP significantly enhanced the NOD2 stimulating activity.
