Protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK) is activated in response to a variety of endoplasmic reticulum stresses implicated in numerous disease states. PERK is implicated in tumorigenesis and cancer cell survival. GSK2606414 is an orally available, potent, and selective PERK inhibitor. GSK2606414 inhibits PERK activation in cells and inhibits the growth of a human tumor xenograft in mice. PERK activation is independent of the large increase in unfolded nascent proteins within the ER following transient global brain ischemia.
