KPT-185 Chemical Properties,Usage,Production

Uses

KPT185 acts as a novel CRM1 inhibitor used in the treatment of acute myeloid leukemia.

Biological Activity

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].
