CD1 Activator

GCB-27a is a CD1d-binding immunostimulant and antitumor agent. GCB-27a binds to CD1d to form a stable complex and presents it to NKT cells, enhancing hydrophobic interactions within the A' pocket of CD1d through branched-chain conformation restriction. GCB-27a induces a Th1-biased immune response, drives IFN?γ production and limits IL-4 levels. GCB-27a is applicable to research related to melanoma lung metastasis.

GCS-12 is a Th1/2-balanced sulfonamide glycolipid with improved interaction with CD1d. GCS-12 is an agonist for natural killer T (NKT) cell, that induces the secretion of cytokine IFN-γ and IL-4, and exhibits immunomodulatory and anti-tumor activities in mice.

GCB-27b is an immunostimulant that binds to CD1d. GCB-27b forms a stable and long-lasting complex with CD1d, which is presented to the TCR of NKT cells to drive immune responses. GCB-27b induces a Th1-skewed immune response in *Mus musculus*, resulting in high expression of IFN?γ with restricted IL-4 levels. GCB-27b is applicable to research related to lung metastasis of melanoma.
