Biological Activity

α-Galactosyl Ceramide (KRN 7000, alpha-GalCer) is a potent NKT cell stimulator and selective CD1d ligand. α-Galactosyl Ceramide stimulates lymphocyte proliferation and enhances antibody production. It shows antiangiogenic, antitumor and potent immunoregulatory effects in vivo. alpha-galactosylceramide (KRN 7000, alpha-GalCer) has shown potent in vivo anti-tumour activity in mice, including against melanoma and the highly specific effect of inducing proliferation and activation of human Valpha24+NKT-cells. α-Galactosylceramide treatment can protect against spontaneous, carcinogen-, or oncogene-induced primary tumor formation in mice. Consistent with a prime role for IFN-γ in NKT cell-mediated tumor responses, a C-glycoside analog of α-Galactosylceramide that preferentially stimulated IFN-γ production is even more effective than α-Galactosylceramide at preventing metastases of the B16 melanoma.

Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
