Abstract

Leucine-rich repeat kinase 2 (LRRK2) is linked to Parkinson's disease and may represent an attractive therapeutic target. Here we report a 2,4-dianilino-5-chloro-pyrimidine, TAE684, a previously reported inhibitor of anaplastic lymphoma kinase (ALK), is also a potent inhibitor of LRRK2 kinase activity (IC(50) of 7.8nM against wild-type LRRK2, 6.1nM against the G2019S mutant). TAE684 substantially inhibits Ser910 and Ser935 phosphorylation of both wild-type LRRK2 and G2019S mutant at a concentration of 0.1-0.3μM in cells and in mouse spleen and kidney, but not in brain, following oral doses of 10mg/kg.

摘要

富含亮氨酸重复激酶 2(LRRK2)与帕金森病有关,可能是一个有吸引力的治疗靶点。在此,我们报告一种 2,4-二苯胺基-5-氯嘧啶,TAE684,它是一种先前报道的间变性淋巴瘤激酶(ALK)抑制剂,也是 LRRK2 激酶活性的有效抑制剂(对野生型 LRRK2 的 IC50 为 7.8nM,对 G2019S 突变体的 IC50 为 6.1nM)。TAE684 在细胞内和小鼠脾和肾中,以 0.1-0.3μM 的浓度显著抑制野生型 LRRK2 和 G2019S 突变体 Ser910 和 Ser935 的磷酸化,但在脑内没有作用,在口服剂量为 10mg/kg 时也是如此。
