Selinexor | Inhibitor of the nuclear export receptor CRM1/XPO1

Selinexor (1393477-72-9) is a potent inhibitor of the nuclear export receptor, chromosome region maintenance 1 (CRM1; Exportin-1 (XPO1)). It exhibited potent growth suppression in various T-cell acute lymphoblastic leukemia (T-ALL) cells (IC50’s = 34-203 nM)1 and pancreatic cancer cells (IC50 ~ 150 nM)2. Selinexor is being investigated as a possible chemotherapeutic in treating multiple types of cancer.3-8 Currently in clinical trials.
