Mechanism of Action

Targets/IC₅₀/Ki	CRM1
In vitro	KPT-185 significantly inhibits leukemia cell proliferation with IC50 ranging from 100 nM to 500 nM, and induces cell-cycle arrest and apoptosis of AML cell lines and primary AML blasts. This compound reduces CRM1 protein protein level and shows a significant nuclear accumulation of CRM1 cargo proteins. It also inhibits proliferation and promotes apoptosis of pancreatic cancer cells without affecting human pancreatic ductal epithelial cells.
