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.
