Synthesis of all stereoisomers of KRN7000, the CD1d-binding NKT cell ligand

KRN7000 is an important ligand identified for CD1d protein of APC, and KRN7000/CD1d complex can stimulate NKT cells to release Th1 and Th2 cytokines. In an effort to understand the structure–activity relationships, we have carried out the synthesis of a complete set of the eight KRN7000 stereoisomers, and their biological activities have been examined.
