the first potent, selective, and CNS-penetrant IRAK4 inhibitors for the treatment of neuroinflammation. Lead compounds from the series were evaluated in CNS PK/PD models of inflammation, as well as a mouse model of ischemic stroke. The SAR optimization detailed within culminates in the discovery of BIO-7488, a highly selective and potent IRAK4 inhibitor that is CNS penetrant and has excellent ADME properties
白细胞介素受体相关激酶 4 (IRAK4) 是先天免疫系统内信号传导的关键节点,可调节炎症细胞因子和趋化因子的产生。中风或创伤性脑损伤 (TBI) 等组织损伤后,损伤相关分子模式(DAMP) 的存在会通过 IRAK4 途径启动信号传导,从而导致前馈炎症循环,最终阻碍患者康复。在此,我们描述了第一个用于治疗神经炎症的有效、选择性和中枢神经系统渗透性 IRAK4 抑制剂。该系列的先导化合物在 CNS PK/PD 炎症模型以及缺血性中风小鼠模型中进行了评估。其中详细介绍的 SAR 优化最终导致 BIO-7488 的发现,这是一种高度选择性和有效的 IRAK4 抑制剂,具有 CNS 渗透性并具有优异的 ADME 特性。
