Notes: GSK2656157 is an inhibitor of protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK; IC50 = 0.9 nM).{32772,32773} It is selective for PERK over a panel of additional kinases.{32772} GSK2656157 blocks both stress-induced PERK autophosphorylation and eIF2α substrate phosphorylation and decreases levels of ATF4 and CHOP in multiple cell lines.{32772} It is orally bioavailable, suppressing PERK autophosphorylation in mouse pancreas and inhibiting the growth of multiple human tumor xenografts in mice.{32772,32773} GSK2656157 inhibits caspase 1 activation in macrophage-like J774.1 cells, preventing LPS-induced IL-1β production, through its effects on the PERK/eIF2α pathway.{32771}
