KRN7000, or ?-GalCer, is a potent agonist for natural killer T (NKT) cells. The
3-hydroxyl group of its phytosphingosine moiety is important for activating NKT
cells, whereas its 4-hydroxyl group is perceived to be less crucial. To
experimentally determine the role of the 4-hydroxyl group, we synthesized the
3-deoxy analogue of ?-GalCer. It was found that 3-deoxy-?-GalCer induced potent
cytokine responses from NKT cells, comparable to those of both ?-GalCer and
4-deoxy-?-GalCer. This result and our docking studies suggest that the effects of
an absence of the 3-hydroxyl group are compensated by the presence of a hydroxyl
group at the C-4 position. Thus, we conclude that the 4-hydroxyl group of
?-GalCer is as important to the mechanism of action as the 3-hydroxyl group and
that the two hydroxyl groups could play individual and cooperative roles in
orienting the glycolipid into the proper position in CD1d to be recognized by the
T cell receptor of NKT cells.
