Brain-permeable. HG-10-102-01 is a potent and selective inhibitor of wild-type LRRK2 and the G2019S mutant (IC₅₀ values are ~20.3 nM and ~ 3.2 nM, respectively). It significantly inhibits Ser910 and Ser935 phosphorylation of both wild-type LRRK2 and G2019S mutant at a concentration of 0.1-0.3 µM in cells. May be a useful tool for Parkinson’s Disease research.
