生物活性:ISRIB 是综合应激反应 (ISR) 的脑渗透抑制剂。ISR 的持续激活与几种神经系统疾病的发展有关,ISR 通过抑制 eIF2B 来抑制翻译。ISRIB 通过促进 eIF2B 的核苷酸交换活性和恢复翻译来抑制 ISR,因此可以用于神经系统疾病的研究。
体外:ISRIB (200 nM, 2 h) 阻断 U2OS 细胞 eIF2α 磷酸化诱导的应激颗粒形成[3]。 MCE has not independently confirmed the accuracy of these methods. They are for reference only.
体内:ISRIB (0.25 mg/kg,腹腔注射,每日) 可恢复朊病毒患病小鼠 eIF2α 磷酸化下游的翻译,对朊病毒患病小鼠具有神经保护作用[2]。 MCE has not independently confirmed the accuracy of these methods. They are for reference only.
