  4. ISRIB

ISRIB is a brain-penetrant inhibitor of integrated stress response (ISR). Persistent activation of the ISR has been linked to the development of several neurological disorders as ISR represses translation through inhibiting eIF2B. ISRIB inhibits the ISR by promoting the nucleotide exchange activity of eIF2B and recovering the translation, and thus can be used for neurological disorders research.

    Description

    ISRIB is a brain-penetrant inhibitor of integrated stress response (ISR). Persistent activation of the ISR has been linked to the development of several neurological disorders as ISR represses translation through inhibiting eIF2B. ISRIB inhibits the ISR by promoting the nucleotide exchange activity of eIF2B and recovering the translation, and thus can be used for neurological disorders research[1][2][3].

    In Vitro

    ISRIB (200 nM, 2 h) blocks stress granule formation induced by eIF2α phosphorylation in U2OS cells[3].

    In Vivo

    ISRIB (0.25 mg/kg, i.p., daily) restores translation in prion-diseased mice at downstream of eIF2α phosphorylation, confering neuroprotection in prion-diseased mice [2].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
