Description:

WARNING: This product is for research use only, not for human or veterinary use.

SSR128129E (SSR) is an potent FGFR inhibitor, which inhibits fibroblast growth factor receptor (FGFR) signaling by binding to the extracellular FGFR domain without affecting orthosteric FGF binding. SSR128129E exhibits allosteric properties, including probe dependence, signaling bias, and ceiling effects. Inhibition by SSR128129E is highly conserved throughout the animal kingdom. Oral delivery of SSR128129E inhibits arthritis and tumors that are relatively refractory to anti-vascular endothelial growth factor receptor-2 antibodies. Thus, orally-active extracellularly acting small-molecule modulators of RTKs with allosteric properties can be developed and may offer opportunities to improve anticancer treatment.

More Info
        
Biological target:
SSR128129E is a FGFR inhibitor with an IC50 of 1.9 μM for FGFR1.
In vitro activity:
SSR12819E radiosensitised radioresistant U87 and SF763 glioblastoma cells. SSR128129E administration to U87 cells increased the radiation-induced mitotic cell death. It also decreased cell membrane availability of the FGFR-1 mainly expressed in these cells, increased this receptor's ubiquitylation, inhibited radiation-induced RhoB activation and modulated the level of hypoxia inducible factor, HIF-1α, a master regulator of hypoxia, thus suggesting a role of FGFR in the regulation of hypoxia pathways. Reference: Eur J Cancer. 2014 Sep;50(13):2351-9. https://pubmed.ncbi.nlm.nih.gov/24953334/
In vivo activity:
SSR128129E may be a promising drug candidate for the prevention of obesity via suppressing adipogenesis. SSR128129E administration significantly reduced the body weight gain and the fat content of mice. SSR128129E did not increase, but decreased the thermogenic capability of both brown and white fat. However, SSR128129E markedly suppressed adipogenesis of adipose tissues. Reference: Mol Biol Rep. 2022 Sep;49(9):8641-8649. https://pubmed.ncbi.nlm.nih.gov/35731366/
