Biological Activity

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.

Targets

XPO1 ^[1]

In vitro
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]
Cell Research	Cell lines	Human CLL cells
	Concentrations	0-10 μM
	Incubation Time	24 h and 48 h
	Method	MTS assay and annexin-V/PI flow cytometry.
Experimental Result Images	Methods	Biomarkers	Images	PMID
	Western blot	XPO1		26654943
	Immunofluorescence	p53 / NPM1 p62 / p53		27323910

In Vivo
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].
Animal Research	Animal Models	NOD-SCID-IL2Rcγ^null (NSG) mice
	Dosages	15 mg/kg
	Administration	by oral gavage

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
