KPT-185
KPT-185 is a selective and irreversible inhibitor of chromosome maintenance protein 1 (CRM1) with IC50 values of 100-500nM [1].
CRM1 is an important nuclear protein export receptor. Blocking CRM1-mediated nuclear export can result in the suppression of tumors. As an inhibitor of CRM1, KPT-185 binds CRM1within the Cys528 site and prevents CRM1from interacting with tumor-suppressor proteins. In the in vitro studies on AML cell lines, KPT-185 inhibits proliferation of a variety of leukemia cells with IC50 values ranging from 100nM to 500nM. It induces cell-cycle arrest at G1 and induces apoptosis. KPT-185 also strongly affects cell colony formation. In addition, the inhibition of CRM1 caused by KPT-185 induces differentiation of AML blast. Besides that, KPT-185 is also found to inhibit proliferation and induce apoptosis of pancreatic cancer cells including Colo-357, HPAC and BxPC-3 [1, 2].
