KPT-251 is a selective inhibitor of nuclear export proteins. It covalently binds to Cys528 in the nuclear export signal-binding groove of CRM1 (exportin 1), inhibiting its nuclear export function. KPT-251 displays potent antileukemic activity with negligible toxicity to normal hematopoietic cells when administered orally to immunodeficient mice engrafted with human AML cells.
