CZC-25146 Hcl is a potent, selective and metabolically stable LRRK2 inhibitor with IC50 of 4.76 nM/6.87 nM for wild type LRRK2 and G2019S LRRK2 respectively. IC50 value: 4.76 nM/6.87 nM(wild type/G2019S LRRK2) [1] Target: LRRK2 CZC-25146displayed a very clean profile, it inhibited only five kinases(PLK4, GAK, TNK1, CAMKK2 and PIP4K2C) with high potency, none of which have been classified as predictors of genotoxicity or hematopoietic toxicity. CZC-25146 neither caused cytotoxicity in human cortical neurons at concentrations below 5 μM over a seven-day treatment in culture nor did it block neuronal development in vitro. CZC-25146 possesses favorable pharmacokinetic properties, such as a volume of distribution of 5.4 L/kg and a clearance of 2.3 L/hr/kg that render it suitable for in-vivo studies.
