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.).

Journal of medicinal chemistry, 58(3), 1426-1441 (2015-01-15)
The structure-based design and optimization of a novel series of selective PERK inhibitors are described resulting in the identification of 44 as a potent, highly selective, and orally active tool compound suitable for PERK pathway biology exploration both in vitro
Natalia M Peñaranda-Fajardo et al.
Cell death & disease, 10(10), 690-690 (2019-09-20)
Patients with aggressive brain tumors, named glioblastoma multiforme (GBM), have a poor prognoses. Here we explored if the ER stress/unfolded protein response (UPR) is involved in the pathophysiology of GBM and may provide novel therapeutic targets. Immunohistochemical analyses of a

Saxagliptin (Saxa), a dipeptidyl dipeptidase-4 (DPP-4) inhibitor, is widely used for the treatment of type 2 diabetes mellitus. It has been documented to have immunomodulatory and anti-inflammatory actions. Our objective was to delineate the protective effect and the underlying mechanism
Diego Rojas-Rivera et al.
Cell death and differentiation, 24(6), 1100-1110 (2017-04-30)
Accumulation of unfolded proteins in the endoplasmic reticulum (ER) causes a state of cellular stress known as ER stress. The cells respond to ER stress by activating the unfolded protein response (UPR), a signaling network emerging from the ER-anchored receptors
Mohamed Mahameed et al.
Cell death & disease, 10(4), 300-300 (2019-04-02)
IRE1, PERK, and ATF6 are the three transducers of the mammalian canonical unfolded protein response (UPR). GSK2606414 is a potent inhibitor of PERK, while KIRA6 inhibits the kinase activity of IRE1. Both molecules are frequently used to probe the biological
