IC50: 6 nM (PERK)
体外研究(In Vitro)
AMG PERK 44 has an IC50 of 84 nM for cell pPERK. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
AMG PERK 44 (orally; 3-100 mg/kg) robustly inhibits PERK autophosphorylation in this assay (ED 50 =3 mg/kg; ED 90 =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.
AMG PERK 44 (iv; 1 mg/kg) has a CL of 1.6 L/h?kg, a V ss of 3.6 L/kg and MRT of 2.3 hours in Sprague-Dawley rats and male CD-1 mice. has not independently confirmed the accuracy of these methods. They are for reference only.
