Description
OverviewA cell-permeable, irreversible, triazole-containing heterotricyclic CRM1 inhibitor that effectively blocks CRM1-mediated nuclear export (4 h 1µM in U2OS cells) via covalent interaction with CRM1 NES- (nuclear export signal) binding groove cysteine (Cys528 in human). Exhibits antileukemic activity against primary human CD19+ CLL (IC50 <500 nM) via apoptosis induction even in the presence of stroma cells or other known CLL survival stimuli, while exhibiting little cytotoxicity toward CD56+ NK cells from healthy donors (1 µM; up to 72 h). Reported to prolong the survival of SCID mice (75 mg/kg p.o.) engrafted with murine Eμ-TCL1 or human MV4-11 leukemia in vivo.

Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water.

SynonymsKPT251, (Z)-2-(2-(3-(3,5-bis(trifluoromethyl)phenyl)-1H-1,2,4-triazol-1-yl)vinyl)-1,3,4-oxadiazole, Exportin 1 Inhibitor IV, Chromosome Region Maintenance 1 Protein Inhibitor IV, CRM1 Inhibitor IV, XPO1 Inhibitor IV
DescriptionA cell-permeable, irreversible, triazole-containing heterotricyclic CRM1 inhibitor that effectively blocks CRM1-mediated nuclear export (complete HIV-1 Rev nuclear retention after 4 h 1µM incubation in RevGFP-expressing U2OS cells) via covalent interaction with Cys528 (numbering based on human sequence) in the CRM1 NES- (nuclear export signal) binding groove, while being ineffective against CRM1C528S-Rev interaction in RevBFP-expressing HeLa cells. Exhibits antileukemic activity in primary human CD19+ CLL (chronic lymphocytic leukemia) cultures (IC50 <500 nM) via apoptosis induction even in the presence of stroma cells or other known CLL survival stimuli, while exhibiting little cytotoxicity toward CD56+ NK cells from healthy donors (1 µM; up to 72 h). KPT-251 is orally available in mice (tmax = 0.5 h; t1/2 = 3.83 h; Cmax = 439 ng/mL; AUCINF = 1590 h·ng/mL; 10 mg/kg p.o.) and reported to prolong the survival of SCID mice (75 mg/kg p.o.) engrafted with murine Eμ-TCL1 (mean survival time = 130.5 d vs. 72 d, respectively, with or without treatment) and human MV4-11 leukemia (62% survival rate on d 60 vs. 24% on d 34, respectively, with or without treatment) in vivo.
