GSK2578215A induces a dose-dependent inhibition of Ser910 and Ser935 phosphorylation in both wild-type LRRK2 and LRRK2[G2019S] stably transfected into HEK293 cells, and induces similar dose-dependent Ser910 and Ser935 dephosphorylation of endogenous LRRK2 in mouse Swiss 3T3 cells. In SH-SY5Y cells, GSK2578215A impairs the autophagy flux by altering autophagosome–lysosome fusion, and induces mitophagy though induction of Drp-1-mediated mitochondrial fission and mitochondrial-derived ROS signaling.
In vivo
In vivo, GSK2578215A (100 mg/kg i.p.) inhibits Ser910 and Ser935 phosphorylation in mouse spleen and kidney, but not in brain.
