S7307 GSK2606414 GSK2606414 is an orally available, potent, and selective PERK inhibitor with IC50 of 0.4 nM, displaying at least 100-fold selectivity over the other EIF2AKs assayed. GSK2606414 impairs GANT-61 induced autophagy in NB cells with MYCN amplification. GSK2606414 exacerbates ER stress-induced apoptosis in HCT116 cells while reduces the apoptosis in SIL1 KD HeLa cells.
Cell, 2024, 187(14):3652-3670.e40
Autophagy, 2024, 1-22.
Exp Mol Med, 2024, 56(2):408-421.
S7033 GSK2656157 GSK2656157 is an ATP-competitive and highly selective inhibitor of PERK with IC50 of 0.9 nM in a cell-free assay, 500-fold greater against a panel of 300 kinases. GSK2656157 decreases apoptosis and inhibits excessive autophagy.

E1761New AMG PERK 44 AMG PERK 44 is a highly selective and orally active inhibitor of PERK with an IC50 of 6 nM. AMG PERK 44 exhibits 1000-fold and 160-fold selectivity over GCN2 and B-Raf, respectively.
S6952 MK-28 MK-28 is a potent and selective activator of PERK. MK-28 exhibits an IC50 ~3-fold higher than CCT020312 in rescuing mutant huntingtin protein (mHtt)-expressing striatal neurons from apoptosis. MK-28 exhibits remarkable pharmacokinetic properties and high BBB penetration in mice.
