α-Galactosylceramide (KRN7000) is a synthetic glycolipid with antitumorial and immunostimulatory and is a very potent NKT cell agonist and binds effectively to CD1d. The complex of α-Galactosylceramide and CD1d can bind to the T cell antigen receptor of NKT cells.

KRN7000 analog 3 (Compound 14), an α-GalCer analog featuring a 4-phenoxy substituent, acts as an iNKT agonist. This compound induces higher levels of IL-2 cytokine secretion in mNK1.2 cells (ranging from 49.2 to 62.6 ng/mL) compared to α-GalCer (44.1 ng/mL). KRN7000 analog 3 shows potential for research in anti-tumor agents and vaccine adjuvants.

KRN7000 analog 8 (compound 8) is a variant of KRN7000 that demonstrates a strong stimulatory effect on IL-2 production. Compared to KRN7000, it induces lower levels of IFN-γ but results in higher IL-4 production.

KRN7000 analog 1 stimulates a strong Th1-biased immune response by inducing interferon-γ (IFN-γ) and reducing interleukin-4 (IL-4). This compound shows potential as an antitumor agent and vaccine adjuvant.

KRN7000 analog 2 is an iNKT agonist that shows promise for use in research pertaining to antitumor drugs and vaccine adjuvants.

α-Galactosylceramide analog 8 (α-GalCer analog 8) is a triazole derivative of α-galactosylceramide. [1] It increases IL-2 secretion by DN32.D3 NKT hybridoma cells when co-cultured with CD1d-transfected RBL cells pre-loaded with α-GalCer analog 8 at a concentration of 32 ng/ml. α-GalCer analog 8 (32 ng/ml) induces IL-4 secretion to a greater extent than the synthetic α-GalCer KRN 7000 in mouse splenocytes in vitro and in mouse serum following administration of a 1 µg per animal dose, indicating a Th2 response.
