Description: Selinexor, also known as KPT-330, is an orally bioavailable, potent and selective XPO1/CRM1 Inhibitor. Selinexor is effective in acquired resistance to ibrutinib and synergizes with ibrutinib in chronic lymphocytic leukemia. Selinexor potentiates the antitumor activity of gemcitabine in human pancreatic cancer through inhibition of tumor growth, depletion of the antiapoptotic proteins, and induction of apoptosis. Selinexor has strong activity against primary AML cells while sparing normal stem and progenitor cells.
