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. |

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.84 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 2.5 mg/mL (5.84 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*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.
