Product Description

Eltanexor (is discontinued) formerly known as KPT-8602, is a second-generation exportin-1 inhibitor. KPT-8602 displays potent activity against acute lymphoblastic leukemia. KPT-8602 is well tolerated and highly active against AML blasts and leukemia-initiating cells. Eltanexor shows improved efficacy and in vivo tolerability in hematological malignancies.

Additional Infomation
Eltanexor is a member of the class of triazoles that is 1H-1,2,4-triazole substituted by (1E)-3-amino-3-oxo-2-(pyrimidin-5-yl)prop-1-en-1-yl and 3,5-bis(trifluoromethyl)phenyl groups at positions 1 and 3, respectively. It is a second-generation exportin 1 inhibitor that is currently in phase II clinical trial for the treatment of patients with higher relapsed/refractory myelodysplastic neoplasms. It has a role as an exportin 1 inhibitor, an antineoplastic agent and an apoptosis inducer. It is a member of (trifluoromethyl)benzenes, a member of triazoles, a member of pyrimidines, an enamide and a primary carboxamide.
Eltanexor is under investigation in clinical trial NCT02649790 (Study of the Safety, Tolerability and Efficacy of KPT-8602 in Patients With Relapsed/refractory Cancer Indications).
Eltanexor is an orally bioavailable inhibitor of exportin-1 (XPO1; chromosome region maintenance 1 protein homolog; CRM1), with potential antineoplastic activity. Upon administration, eltanexor binds to the XPO1 cargo binding site, which prevents the XPO1-mediated nuclear export of cargo proteins such as tumor suppressor proteins (TSPs), including p53, p73, BRCA1/2, pRB, FOXO, and other growth regulatory proteins and leads to their selective accumulation in the nuclei of tumor cells. As a selective inhibitor of nuclear export (SINE), KPT-8602 restores the nuclear localization and function of tumor suppressing proteins which leads to the induction of apoptosis in tumor cells. XPO1, the major export factor that transports proteins from the nucleus to the cytoplasm, is overexpressed in a variety of cancer cell types while minimally expressed in normal, healthy cells. The export of tumor suppressor proteins into the cytoplasm prevents them from initiating apoptosis and leads to uncontrolled tumor cell proliferation.
These protocols are for reference only. InvivoChem does not independently validate these methods.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
