Abstract:
The present disclosure relates to synthetic alpha-galactosyl ceramide (.alpha.- GalCer) analogs, and their use as immunotherapies, adju-vants, and antiviral, antibacterial, and anticancer agents. In one aspect, a method of activating a cy-tokine response in a subject includes administer-ing an effective amount of a compound to a sub-ject, wherein the subject has an adaptive immune system that includes a population of cells, the population including at least one lymphocyte and at least one antigen-presenting cell, and wherein the compound is represented by the structure of formula 1 :; or a pharmaceutically acceptable salt thereof; forming a complex between the com-pound and the antigen-presenting cell, wherein the formation of the complex results in the activa-tion of a receptor on the lymphocyte; and activat-ing the lymphocyte to produce the cytokine re-sponse.

Abstract:
Glycosphingolipids (GSLs) bearing α-glucose (α-Glc) that preferentially stimulate human invariant NKT (iNKT) cells are provided. GSLs with α-glucose (α-Glc) that exhibit stronger induction in humans (but weaker in mice) of cytokines and chemokines and expansion and/or activation of immune cells than those with α-galactose (α-Gal) are disclosed. GSLs bearing α-glucose (α-Glc) and derivatives of α-Glc with F at the 4 and/or 6 positions are provided. Methods for iNKT-independent induction of chemokines by the GSL with α-Glc and derivatives thereof are disclosed. Methods for immune stimulation in humans using GSLs with α-Glc and derivatives thereof are provided.
