Abstract

Mincle, a C-type lectin receptor (CLR), senses certain lipid conjugates, leading to the activation of the innate immune system. The lipid conjugate ligands include glyco-, glycero-, and mannitol lipids. Recently, a fungal β-mannosyloxymannitol glycolipid demonstrating a novel architecture, “44-2,” was isolated from the fungus Malassezia and displayed potent Mincle-mediated signaling activity. For this study, we synthesized the diastereomeric pair of mannosyloxymannitol glycolipids and their analogues and analyzed the structure-activity relationships of Mincle-mediated signaling. The results suggest that the dimannosyl-fatty acid moiety in the mannosyloxymannitol glycolipid-type structure plays a major role in the molecular recognition of Mincle.
