Efficient strategies to functionalize natural, unprotected PGN molecules are highly desirable for advancing the biological studies of PGNs. In this work, we developed a facile chemoselective strategy to derivatize the anomeric C1 position of reducing 2-acetamido sugars, a characteristic shared by most PGNs that contain reducing <i>N</i>-acetylmuramic acid. Upon treatment with imidazole-dithiocarbamate-azide (<b>IDA</b>), we showed that natural reducing 2-acetamido PGNs are readily converted to oxazoline intermediates under aqueous conditions. Serendipitously, we discovered that simply freeze-drying the reaction mixture promotes glycosidation of the oxazoline glycosyl donor, leading to PGN-DTC-azide products with high stereoselectivity and yields. Importantly, our chemoselective azidation strategy shows a broad substrate scope, including diverse gut microbiota-derived PGNs, such as muropeptides and natural oligosaccharides. The azido moiety in PGN-DTC-azides serves as a versatile handle for further functionalization, leading to fluorescent or photo-cross-linking PGN probes that maintain the immunological activities of natural PGNs. Importantly, we demonstrate the successful generation of the IgG1 monoclonal antibody 7F8 in mice, which specifically recognizes GlcNAc-MurNAc-DTC-azide as its antigen.

Specifically, clusters of interaction-prone amino acids, including Trp and Arg, along the sequence form correlated segments, and these correlated segments, rather than individual residues, drive the phase separation of many IDPs.
