Furthermore, compound 26 had a good pharmacokinetic profile (the oral bioavailability in rats was 41.38%) and an in vivo safety profile (the LD50 in mice was greater than 708 mg·kg–1). In the in vivo efficacy assays, the combination of 26 and the prolyl hydroxylase inhibitor, AKB-6548, was confirmed for the first time to synergistically increase the plasma erythropoietin level in mice (from 260 to
激活缺氧诱导因子 2 (HIF-2) 已成为一种有效的肾性贫血治疗策略。在这里,苯并异噻唑衍生物26被发现是一种新型 HIF-2α 激动剂,它在荧光素酶报告基因检测中首次表现出纳摩尔活性(EC 50 = 490 nM,E max = 349.2%)。分子动力学模拟表明,26可以变构增强 HIF-2 二聚化。此外,化合物26具有良好的药代动力学特征(大鼠的口服生物利用度为 41.38%)和体内安全性特征(小鼠的 LD 50大于 708 mg·kg –1)。在体内功效测定中,26和脯氨酰羟化酶抑制剂AKB-6548的组合首次被证实可协同增加小鼠血浆促红细胞生成素水平(从 260 至 2296 pg·mL –1)并缓解多柔比星诱导的斑马鱼贫血. 这些结果为 HIF-2α 激动剂和肾性贫血的治疗提供了新的见解。
