KRN2 bromide is a potent, selective inhibitor of nuclear factor of activated T cells (NFAT5, IC50= 0.1 μM).

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.

KRN-633 is an effective VEGFR inhibitor. The IC50s of KRN-633(KRN633) for VEGFR1, VEGFR2, and VEGFR3 is 170, 160 and 125 nM, respectively.

KRN2 has potential to treat NFAT5-mediated Chronic Arthritis. KRN2 is a selective inhibitor of nuclear factor of activated T cells (NFAT5), with an IC50 of 100 nM.
