C16, also known as GW-506033X or PKR Inhibitor. C16 binds the ATP-binding site of PKR and blocks autophosphorylation with an IC50 value of 186-210 nM. GW-506033X protects human neuroblastoma cells against cell damage triggered by tunicamycin-mediated endoplasmic reticulum stress. PKR inhibitor C16 prevents apoptosis and IL-1β production in an acute excitotoxic rat model with a neuroinflammatory component. PKR inhibitor C16 binds efficiently with human microtubule affinity-regulating kinase 4.
