set out to develop LRRK2 inhibitors to test this hypothesis. A high throughput screen of our compound collection afforded a number of promising indazole leads which were truncated in order to identify a minimum pharmacophore. Further optimization of these indazoles led to the development of MLi-2 (1): a potent, highly selective, orally available, brain-penetrant inhibitor of LRRK2.
富含亮氨酸的重复激酶2(LRRK2)是一种大型的多结构域蛋白,除其他区域外,还包含一个激酶结构域和GTPase结构域。具有在激酶结构域中获得功能突变(例如最普遍的G2019S突变)的个体与帕金森氏病(PD)发生的风险增加相关。鉴于这种抑制LRRK2激酶活性作为影响疾病进展的潜在手段的基因验证,我们的团队着手开发LRRK2抑制剂来验证这一假设。我们化合物收集物的高通量筛选提供了许多有前途的吲唑线索,这些线索被截短以鉴定最小的药效团。这些吲唑的进一步优化导致MLi-2(1):一种有效的,高度选择性的,口服可得的LRRK2脑渗透抑制剂。
