| Description | Eltanexor (KPT-8602, ONO-7706，ATG-016) is a second-generation, orally bioavailable XPO1 (also known as CRM1) inhibitor with IC50 values of 20−211 nM in 10 AML lines after 3 days exposure. | |||||||||

| In vitro |
KPT-8602 is a potent inhibitor of AML cells in cell-based viability assays[1]. KPT-8602 inhibits XPO1/cargo interactions and nuclear export, induces apoptosis of primary CLL cells and significantly inhibits proliferation of diffuse large B-cell lymphoma cell lines[2] |

| In vivo | KPT-8602 is orally bioavailable and has similar pharmacokinetic properties to selinexor, but has markedly reduced (approximately 30-fold less) penetration across the blood−brain barrier. Toxicology studies in rats and monkeys indicate that KPT-8602 has a substantially better tolerability profile, probably due to its inability to penetrate into the CNS, with reduced anorexia, malaise and weight loss compared to selinexor. KPT-8602 exhibits superior anti-leukemic activity and better tolerability in the AML PDX models tested, with nearly complete elimination of human AML cells in the AML-CN model. KPT-8602 is minimally toxic to normal hematopoietic stem and progenitor cells[1]. KPT-8602 does not accumulate in plasma after repetitive dosing and prolongs survival in a human leukemia xenograft model of AML[2]. |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
