What is GW5074?

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.

The Uses of GW5074

GW5074 has been used as a specific inhibitor of cRaf1 in C2 murine skeletal myoblasts, HT-29 colorectal adenocarcinoma cell line and neutrophils.

What are the applications of Application

GW 5074 is an inhibitor of c-Raf-1 kinase and PMA-mediated activation of ERK1/2

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
