Loss of proliferation in ATL-derived cell lines by the Pim-kinase inhibitors, Smi-4a (C). Cell counts were repeated at least twice. Results represent the percentage of cells alive after 5 days of Pim inhibitor treatment, compared with 5 days treated with DMSO. For Smi-4a treatment, cells were treated with 0, 10, or 20 μM Smi-4a. Normal PBMCs (n = 2) were used as a control. Western blots indicate loss of Pim1 targets, p-4EBP1 (Thr37/46), p-p70S6K (Thr389), and loss of pBad (Ser20) (negligible for Smi-4a) after 24 hours with 0, 10, 20, or 40 μM Smi-4a or DMSO control.

|Description||SMI-4a (TCS PIM-1 4a) is a potent inhibitor of Pim1 with IC50 of 17 nM, modestly potent to Pim-2, does not significantly inhibit any other serine/threonine- or tyrosine-kinases.|
|Features||SMI-4a (5μM) synergizes with rapamycin (5 nM) to cause significant growth inhibition of leukemic cells.|
SMI-4a is an ATP competitive inhibitor of Pim1 with IC50 of 17 nM. SMI-4a shows high selectivity for Pim1 against a panel of kinases. SMI-4a inhibits the in vitro phosphorylation by Pim-1 of the known substrate, the translational repressor 4E-BP1. SMI-4a (5μM) inhibits pancreatic and leukemic cells growth. SMI-4a reduces phosphorylation of the Pim target Bad in prostate and hematopoietic cells. SMI-4a causes cell cycle arrest and reverses the antiapoptotic activity of Pim-1. SMI-4a increases the amount of p27Kip1 in the nucleus. SMI-4a treatment of pre-T-LBL inhibits the mTOR pathway. SMI-4a reduces MYC protein expression in pre-T-LBL. SMI-4a treatment induces up-regulation of MAPK pathway. 
|In vivo||SMI-4a (60 mg/Kg) treatment twice daily significantly reduce tumor size and is well tolerated. Tumors harvested 1 hour after the final oral gavage of SMI-4a demonstrates decreased phosphorylation of p70 S6K compared with tumors from mice treated with vehicle, whereas in comparison total p70 S6K expression isunchanged. |
|In vitro||DMSO||55 mg/mL (201.29 mM)|
|Ethanol||32 mg/mL (117.11 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
30% PEG400+0.5% Tween80+5% propylene glycol
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

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.
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 MSDS / COA (available on product pages).
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 MSDS / 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.
