MedKoo CAT#: 206469

CAS#: 855527-92-3 (R-isomer)

Description: NBI-74330 is an antagonist of CXC chemokine receptor 3 (CXCR3) with IC50 values of 7nM to18nM. NBI-74330 attenuates atherosclerotic plaque formation in LDL receptor-deficient mice. Chemokine receptor CXCR3 promotes growth of glioma. CXCR3 antagonism exerts a direct anti-glioma effect and this receptor may be a potential therapeutic target for treating human GBM.
