summarize the discovery of highly selective, brain-penetrant, small molecule p38αMAPK inhibitors that are efficacious in diverse animal models of neurologic disorders. A crystallography and pharmacoinformatic approach to fragment expansion enabled the discovery of an efficacious hit. The addition of secondary pharmacology screens to refinement delivered lead compounds with improved selectivity, appropriate
p38αMAPK是丝氨酸/苏氨酸蛋白激酶,是细胞内信号转导网络中的关键节点,可将压力信号转导并放大为生理变化。大量的临床前数据和临床观察证实,p38αMAPK是涉及多种退行性和神经精神性脑疾病的神经炎性反应和突触功能障碍的脑部药物发现靶标。我们总结了在多种神经疾病的动物模型中有效的高选择性,脑渗透性小分子p38αMAPK抑制剂的发现。晶体学和药物信息学方法用于片段扩展使得发现有效的命中成为可能。添加辅助药理学筛选以改进选择性,适当的药效学,和功效。安全性考虑因素和其他辅助药理学筛选推动了优化,该优化提供了目前处于早期临床试验中的候选药物MW01-18-150SRM(MW150)。
