Descripción

General description

A cell permeable chromenone derivative that acts as a dual activator of protein kinase R (PKR) and protein kinase R like kinase (PERK). Induces the phosphorylation of IkBa and thereby activates NF-κB pathway. However, the activation of NF-κB is independent of PKR activity. Induces elF2a phosphorylation and activates its downstream effectors CHOP/GADD153. Does not affect the phosphorylation of Akt, MAP kinase, or 4E-BP1. Inhibits the expression of cyclin D1 and E and blocks the growth of CRL-2813 and MCF-7 cells (IC₅₀ = ~ 10 µM). Also shown to reduce JFH1 hepatitis C virus infectivity (~40% inhibition at 5 µM).
