RIP1 kinase inhibitors starting from a high-throughput screen and the lead-optimization of this series from a lead with minimal rat oral exposure to the identification of dihydropyrazole 77 with good pharmacokinetic profiles in multiple species. Additionally, we identified a potent murine RIP1 kinase inhibitor 76 as a valuable in vivo tool molecule suitable for evaluating the role of RIP1 kinase in chronic
RIP1激酶调节坏死病和炎症,并可能在促成多种人类疾病(包括炎症和神经疾病)中发挥重要作用。目前,RIP1激酶抑制剂已进入早期临床试验,以评估炎性疾病(如牛皮癣,类风湿性关节炎和溃疡性结肠炎)以及神经系统疾病(如肌萎缩性侧索硬化症和阿尔茨海默氏病)。在本文中,我们从高通量筛选开始,研究了有效和高度选择性的二氢吡唑(DHP)RIP1激酶抑制剂的设计,并从具有最小大鼠口服暴露量的铅中对该系列的铅进行了优化,以鉴定二氢吡唑77在多个物种中具有良好的药代动力学特征。此外,我们确定了一种强效的鼠RIP1激酶抑制剂76作为一种有价值的体内工具分子,适用于评估RIP1激酶在慢性疾病模型中的作用。DHP 76在多发性硬化症和人类视网膜色素变性的小鼠模型中均显示出功效。
