Western blot analysis of the expression and activation status (a) of pFGFR, pERK and Bim after treatment of API5-overexpressing cells (a) with either DMSO or SSR128129E.
Exp Mol Med, 2017, 49(9):e374. SSR128129E purchased from Selleck.
(a, d) Cells were treated with indicated concentrations of SSR128129E for 48 h. Cell viability was measured by an MTT assay, and then the concentrations resulting in 50% inhibition of cell viability (IC50 values) were determined. (b, e) Cells were treated with 10 μM of SSR128129E for 12 h. Expression levels of NANOG, pFGFR, FGFR, pERK and ERK in these cells were analyzed by western blot analysis. Numbers below blots indicate the expression as measured by fold change. (c, f) Cells were treated with 10 μM of SSR128129E for 12 h. Flow cytometry analysis of CD44 in these cells. Error bars represent mean±s.d. Data presented are representative of three independent experiments

|Description||SSR128129E is an orally-active and allosteric FGFR1 inhibitor with IC50 of 1.9 μM, while not affecting other related RTKs.|
SSR128129E exhibits more effective activity in cell assay due to its allosteric mechanism. SSR128129E dose-dependently inhibits FGF2-induced EC proliferation and migration with IC50 of 31 nM and 15.2 nM, respectively. As a multi-FGFR inhibitor, SSR128129E inhibits responses mediated by FGFR1-4 and thus results in the blockage of proliferation and/or migration in various cell lines including mPanc02, HEK-hFGFR2WT, PAE-hFGFR1, hB9-myeloma and HUVEC. 
|In vivo||In Arthritis mice, SSR128129E (30 mg/kg, p.o.) inhibits angiogenesis, inflammation, and bone resorption, and reduces the severity of clinical symptoms. In mice bearing various tumor models, SSR128129E (30 mg/kg, p.o.) inhibits both the growth of primary tumors and metastasis. In addition, SSR128129E inhibits growth of anti-VEGFR2-refractory and -sensitive tumor models, and enhances the antitumor activity of anti-VEGFR2.  SSR128129E also inhibits arteriosclerosis in a mouse vein graft model and atherosclerosis in apolipoprotein E-deficient mice. |
Scintillation Proximity Assay, 125I-FGF-2 Binding:SPA protein A beads are supplied as a suspension in PBS at 20 mg/mL, then diluted with binding buffer (KCl, 400 mg/L; MgSO4 200 mg/L; NaCl 6.4 g/L; NaHCO3 3.7 g/L; NaH2PO4 0.141 mg/mL; bis Tris Propane 11.292 g/L; Glucose 4.5 g/L; Gelatin 0.1 %; pH 7.0) at 10 mg/mL. 125I-FGF-2 radioligand and FGFR-1IIIcß - Fc Chimera are diluted into binding buffer. Binding was performed on 96-well plates coated with 0.1 % gelatin. Total assay volume is 0.1 mL. Binding of 125I-FGF-2 is determined by incubation of SPA beads coated with protein A (0.5 mg/assay) with FGFR-1IIIcß - Fc chimera soluble receptor (5 ng/assay), FGF-2 (20 ng/assay) is used for non-specific binding determinations.

* 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.
