Description
GW-5074 (220904-83-6) is a potent inhibitor of cRAF1 kinase (IC50 = 9 nM). Displays 100-fold selectivity for cRAF1 over CDK1, CDK2, c-src, ERK2, MEK, p38, Tie2, VEGFR2 and c-fm. GW-5074 displays neuroprotective effects in vivo via a mechanism that is independent of MEK, ERK, and Akt signaling. Cell permeable.
Uses
GW5074 has been used as a specific inhibitor of cRaf1 in C2 murine skeletal myoblasts, HT-29 colorectal adenocarcinoma cell line and neutrophils.
Biological Activity
Potent, selective and cell-permeable c-Raf1 kinase inhibitor (IC 50 = 9 nM). Displays ≥ 100-fold selectivity for raf kinase over CDK1, CDK2, c-src, ERK2, MEK, p38, Tie2, VEGFR2 and c-fm.
Biochem/physiol Actions
GW5074 is a cRaf1 kinase inhibitor, which is placed immediately downstream of Ras in the Motogen activated protein kinase (MAPK) signaling pathway. It elicits protection in GW5074 prevents degeneration in Huntington′s disease and also have therapeutic potential in treating neurodegenerative disorders. GW5074 in combination with anti-inflammatory drug, dexamethasone, attenuates sidestream smoke-induced airway inflammation.
storage
Desiccate at -20°C
