EB-42168 is a potent, selective G2019S-LRRK2 kinase inhibitor with IC50 of 1.1 nM (pS935-LRRK2) in FRET-based assay, >100-fold selective over WT-LRRR2.

FX2149 (FX 2149) is a potent, BBB permeable inhibitor of LRRK2 GTP binding activity with IC90 of 10 nM, reduces PD-linked mutant LRRK2 variants (G2019S and R1441C) that bound with GTP.

MK-1468 is a potent, selective, brain-penetrant LRRK2 inhibitor with IC50 of 0.4 nM (G2019S LRRK2), potently inhibits the phosphorylation of LRRK2 serine 935 (pSer935) in hPBMCs with IC50 of 2.8 nM.
