Biological Activity

SSR128129E is an orally-active and allosteric FGFR1 inhibitor with IC50 of 1.9 μM, while not affecting other related RTKs.

Customer Product Validations & Biological Datas
Source PLoS One (2013). Figure 3. SSR128129E
Method qPCR
Cell Lines C57BL/6
Concentrations 50 mg/kg/d
Incubation Time -
Results Treatment of apoE-deficient mice with SSR128129E did not affect the mRNA levels of all the receptors but FGFR2, the levels of which were slightly, but significantly, reduced
Cell Experiment
Cell lines Endothelial cells (ECs) and Panc02 tumor cells
Preparation method Cell proliferation of porcine aortic endothelial (PAE) and tumor cell lines is analyzed on exponentially growing cells that are starved for 16 hours in 0.2 % FBS containing medium and seeded at 4,000 cells/well in 96-well microplates. After exposure to mitogens and/or SSR for 72 hours, according to manufacturer’s instructions, assessing the cell proliferation with the use of the CellTiter 96 AQueous One Solution Cell Proliferation Assay . 10 % FBS containing medium is used a positive control
Concentrations ~100 nM
Incubation time 72 hours
Animal Experiment
Animal models Mouse model of Arthritic and mouse tumor model bearing pancreatic tumor cell line Panc02, murine mammary carcinoma cell line 4T1, murine colon cancer cell line CT26, or human breast MCF7/ADR cell line.
Formulation 0.6 % methylcellulose
Dosages ~30 mg/kg
Administration Oral administration
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
