JH-II-127 is a highly potent, selective, and brain penetrant LRRK2 inhibitor, with IC50 of 6.6 nM, 2.2 nM ,47.7 nM for LRRK2-wild-type, LRRK2-G2019S, LRRK2-A2016T.IC50 value: 2.2 n(LRRK2-G2019S), 6.6 nM(LRRK2-wild-type), 47.7 nM (LRRK2-A2016T)Target: LRRK2JH-II-127 is a potent and selective inhibitor of both wild-type and G2019S mutant LRRK2. JH-II-127 substantially inhibits Ser910 and Ser935 phosphorylation of both wild-type LRRK2 and G2019S mutant at a concentration of 0.1-0.3 uM in a variety of cell types and is capable of inhibiting Ser935 phosphorylation in mouse brain following oral delivery of doses as low as 30 mg/kg.
