mMincle or hMincle revealed that the hMincle agonist activity of all diesters was superior to that of the current lead trehalose glycolipid adjuvant TDB, while the activity of several monoesters was similar to that of their diester counterparts for mMincle, but all showed reduced hMincle agonist activity. Taken together, diesters 2d–g are thus potent Mincle agonists and promising vaccine adjuvants.

fungal glycolipid fusaroside. The first total synthesis of the proposed structure involved construction of the complex, branched lipid chain having a variety of alkenes with E stereochemistry and attachment of the masked α,β-unsaturated β-keto acid at the O-4 position of trehalose as key steps. We propose a revision in the structure of fusaroside, particularly the position of olefins in the lipid chain
