Biochem/physiol Actions

AMG PERK 44 (AMG44) is an orally active (F = 46% (mouse) & 55% (rat) post 2.5 mg/kg po.), active site-targeing, potent and highly selective PERK (EIF2AK3) inhibitor (IC50 = 6 nM; GCN2 IC50 = 7.3 μM, b-Raf IC50 >1 μM, <65% inhibition at 1 μM against 387 kinases). AMG44 inhibits cellular PERK autophosphorylation (pT980 IC50 = 84 nM; HT1080 T-REx-PERK-FLAG transfectants) and ER stress-induced bulk protein synthesis (IC50 = 400 nM; U2OS), as well as PERK pT980 in HT1080 Matrigel plug implant in mice in vivo (ED50 = 3 mg/kg & ED90 = 60 mg/kg 4 hr post po.).
Orally active, potent and highly selective tool compound for probing PERK (EIF2AK3) pathway both in vitro and in vivo.
