|Overview||The cell-permeable trans diastereomer of a bis-glycolamide compound that acts as a potent and selective blocker of eIF2α/eIF2S1 Ser51 phosphorylation-initiated unfold protein response/UPR (Effec. conc. 25 to 200 nM in HEK293T, HeLa, MEF, U2OS cultures) upon ER stress induction. Although noncytotoxic in the absence of ER stress, ISRIB does cause enhanced apoptotic cell death upon ER stress induction by Thapsigargin/Tg (100 to 500 nM; Cat. Nos. 586005 & 586006) or Tunicamycin/Tm (2 to 5 µg/mL; Cat. No. 654380) treatment. Reported to exhibit good pharmacokinetics with blood-brain permeability in mice and significantly enhance learning and long-term memory in mice (0.25 mg/kg/d i.p.) and rats (25 ng/0.5 µL/275-350 g rat; amygdala administration via cannulation) in vivo. Although the exact molecular target is not yet established, ISRIB most likely exerts its effect by modulating the interaction between the guanine nucleotide exchange factor eIF2B and the phosphorylated eIF2α (pS51).|
