Effects of XL413 plus pirfenidone on 10T1/2 cells morphology, proliferation and TGF-β1-induced α-SMA expression. Cells were exposed to control, XL413 (10 μM), pirfenidone (1 mg/ml) or XL413 plus pirfenidone. (G) Laser confocal scanning was used for visualization of α-SMA protein expression and cellular morphological changes.

|Description||XL413 (BMS-863233) is a potent and selective cell division cycle 7 homolog (CDC7) kinase inhibitor with IC50 of 3.4 nM, showing 63-, 12- and 35-fold selectivity over CK2, Pim-1 and pMCM2, respectively. Phase 1/2.|
In MDA-MB-231T and Colo-205 cell lines, XL413 results in inhibition of CDC7 specific phosphorylation of MCM2. XL413 also inhibits the cell proliferation, decreases cell viability and elicits the caspase 3/7 activity in Colo-205 cells. Moreover, XL413 results in modified S phase progression that subsequently leads to apoptotic cell death. 
|In vivo||In a Colo-205 xenograft model, XL413, at the 3 mg/kg dose, causes 70% inhibition of phosphorylated MCM2, and causes significant tumor growth regression at the 100 mg/kg dose. |
CDC7 kinase assay :Kinase activity and compound inhibition are determined using the luciferase-luciferin-coupled chemiluminescence assay and measured as the percentage of ATP utilized following the kinase reaction in a 384-well format. The final CDC7 kinase assay condition is 6 nM CDC7/ASK, 1 μM ATP, 50 mM Hepes pH 7.4, 10 mM MgCl2, 0.02% BSA, 0.02% brij 35, 0.02% tween 20 and 1 mM DTT. It is worthy to note that the CDC7/ASK protein exhibits substrate-independent ATP utilization. All kinase reactions are incubated at room temperature for 1-2 h.

* 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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × 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.
