What is (Z)-3-(3-(3,5-bis(trifluoroMethyl)phenyl)-1H-1,2,4-triazol-1-yl)-1-(3,3-?

Description

KPT-276 is an orally bioavailable inhibitor of Exportin 1 (XPO1/CRM1) with anticancer activity. In vivo, KPT-276 (150 mg/kg) increases survival and reduces spleen weight and white blood cell count in an MV4-11 acute myeloid leukemia (AML) mouse xenograft model. It also reduces tumor volume and increases survival in a BT 145 glioblastoma mouse xenograft model when administered at a dose of 75 mg/kg.
