Natural killer T cell (NKT) T cell receptor (TCR) agonist. Derivative of α-GalCer (the first defined and most potent agonistic antigen of TCR known so far). Stimulates the production of smaller amounts of IFN-γ than α-GalCer, but  induces equal or greater IL-4 secretion in mouse models.

Scientific Background:Natural killer T (NKT) cells are a unique subset of T cells. Unlike other T cells, NKT recognize glycolipid antigens presented by the major histocompatibility complex (MHC) class I-like molecule CD1d. Upon recognition of the CD1d/glycolipid complex through TCR, NKT cells rapidly produce Th1 and Th2 cytokines such as IFN-γ and IL-4. The most well-studied example is the CD1d-presented TCR antigen α-galactosylceramide (α-GalCer). α-GalCer, originally isolated from the marine sponge Agelas mauritianus, has been shown to be a highly potent, immunomodulatory compound. Meanwhile, various structural analogs of α-GalCer have been produced and their immunomodulating activities are being tested to assess the potential as drugs for the treatment of various autoimmune diseases and cancer.
