Description: GW5074 is a c-Raf inhibitor. GW5074 has no direct effect on the activities of several apoptosis-associated kinases when assayed in vitro. In contrast to its effect in vitro, treatment of neurons with GW5074 causes c-Raf activation (when measured in vitro in the absence of the drug) and stimulates the Raf-MEK-ERK pathway. GW5074 prevents neurodegeneration and improves behavioral outcome in an animal model of Huntington's disease. GW5074 could have therapeutic value against neurodegenerative pathologies in humans.
