This product has been discontinued. Selinexor (also known as KPT-330) is an orally bioavailable, potent and selective CRM1 inhibitor. Selinexor is effective in acquired resistance to ibrutinib and synergizes with ibrutinib in chronic lymphocytic leukemia. Selinexor potentiates the antitumor activity of gemcitabine in human pancreatic cancer through inhibition of tumor growth, depletion of the antiapoptotic proteins, and induction of apoptosis.
| ln Vitro |
KPT-330, a clinical candidate counterpart of KPT-185, causes a fast apoptotic response and has comparable effects on T-ALL cell survival. With IC50 values ranging from 34 to 203 nM, KPT-330 also inhibits the proliferation of MOLT-4, Jurkat, HBP-ALL, KOPTK-1, SKW-3, and DND-41 cell lines [1].

| ln Vivo |
Selinexor (KPT-330) has no negative effects on healthy hematopoietic cells while dramatically suppressing the proliferation of AML (MV4-11) and T-ALL (MOLT-4) cells in vivo [1]. In SCID mice exhibiting diffuse human MM bone lesions, KPT-330 prolongs survival by inhibiting MM-induced osteolysis. Furthermore, by inhibiting RANKL-induced NF-κB and NFATc1, KPT-330 directly reduces osteoclastogenesis and bone resorption while having no effect on osteoblasts and BMSCs [2].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.64 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 900 μL of corn oil and mix evenly. Solubility in Formulation 2: ≥ 2.08 mg/mL (4.69 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 20.8 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. View More
Solubility in Formulation 3: 2.08 mg/mL (4.69 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. Solubility in Formulation 4: 2% DMSO +49% PEG 300 +dd H2O: 5mg/mL |

*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
