The present invention provides N-acetyl-muramic acid (NAM) derivatives having Formula I, wherein Xa is selected from the group consisting of X1-X59, Ya is selected from the group consisting of H, monophosphate, uridine diphosphate and ethyl azide linker prepared from 2-azido-ethanol, and Za is selected from the group consisting of OH, an ethylene diamine coupled fluorophore, a peptide and a peptide with an ethylene diamine coupled fluorophore, wherein the peptide is selected from the group consisting of a monopeptide, a dipeptide, a tripeptide and a pentapeptide. Also provided are methods for synthesizing NAM derivatives and methods for modulating Nod2 in cells, modifying bacterial cell wall or modulating innate immune response by a subject to bacterial cells upon exposure to NAM derivatives.
本发明提供具有式I的N-乙酰-壳聚糖酸(NAM)衍生物,其中Xa选自X1-X59组,Ya选自H、磷酸单酯、尿苷二磷酸和由2-叠氮乙醇制备的乙基叠氮连接剂组,Za选自OH、乙二胺偶联的荧光素、肽和乙二胺偶联的肽,其中肽选自单肽、二肽、三肽和五肽组。还提供了合成NAM衍生物的方法以及通过暴露于NAM衍生物后调节细胞中Nod2、修改细菌细胞壁或调节受试者对细菌细胞的固有免疫反应的方法。
