• Structure-activity and structure-property relationships of novel Nrf2 activators with a 1,2,4-oxadiazole core and their therapeutic effects on acetaminophen (APAP)-induced acute liver injury

  The antioxidant function induced by Nrf2 protects the liver from damage. We found a novel Nrf2 activator named compound 25 via structural modification of compound 1 we previously reported. In vitro, compound 25 induced Nrf2 transport into the nucleus and protected hepatocyte L02 cells from APAP-induced cytotoxicity via activating the Nrf2-ARE signaling pathway. In vivo, 25 exhibited therapeutic effects

  Nrf2诱导的抗氧化功能可保护肝脏免受损害。我们通过先前报道的化合物1的结构修饰发现了一种名为化合物25的新型Nrf2活化剂。在体外，化合物25通过激活Nrf2-ARE信号通路，诱导Nrf2转运到细胞核中，并保护肝细胞L02细胞免受APAP诱导的细胞毒性作用。在体内，通过上调Nrf2依赖性抗氧化酶和下调血清中的肝损伤标记物，在对乙酰氨基酚（APAP）诱发的急性肝损伤的小鼠模型中，有25种药物具有治疗作用。在一起，这些结果表明25是有效的Nrf2 / ARE激活剂体外和体内。化合物25的类药物特性进一步揭示了其作为治疗急性肝损伤的治疗药物的潜力。
