In Vitro	AMG PERK 44 has an IC50 of 84 nM for cell pPERK[1].
In Vivo	AMG PERK 44 (orally; 3-100 mg/kg) robustly inhibits PERK autophosphorylation in this assay (ED50=3 mg/kg; ED90=60 mg/kg at the 4 hours time point), and >50% target coverage is maintained for 24 h in a time course PD assay when dosed at 100 mg/kg po[1]. AMG PERK 44 (iv; 1 mg/kg) has a CL of 1.6 L/h•kg, a Vss of 3.6 L/kg and MRT of 2.3 hours in Sprague-Dawley rats and male CD-1 mice[1]. Animal Model: Four- to six-week old naive athymic nude mice[1] Dosage: 3, 10, 30, 100 mg/kg Administration: Orally Result: Robustly inhibited PERK autophosphorylation in this assay (ED50=3 mg/kg; ED90=60 mg/kg at the 4 hours time point). Animal Model: Sprague-Dawley rats and male CD-1 mice[1] Dosage: 1 mg/kg (Pharmacokinetic Analysis) Administration: Iv Result: Had a CL of 1.6 L/h•kg, a Vss of 3.6 L/kg and a MRT of 2.3 hours.
