SSR128129E is an orally-active and allosteric FGFR1 inhibitor with IC50 of 1.9 μM, while not affecting other related RTKs.
|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|
|Incubation time||72 hours|
|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|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|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.
|Solubility||DMSO 50 mg/mL|
|Source||PLoS One (2013). Figure 3. SSR128129E|
|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|
