Abstract

A library of mannose- and fucose-based glycomimetics was synthesized and screened in a microarray format against a set of C-type lectin receptors (CLRs) that included DC-SIGN, DC-SIGNR, langerin, and dectin-2. Glycomimetic ligands able to interact with dectin-2 were identified for the first time. Comparative analysis of binding profiles allowed their selectivity against other CLRs to be probed.
