Leucine-rich repeat kinase 2 (LRRK2) has drawn significant interest in the neuroscience research community because it is one of the most compelling targets for a potential disease-modifying Parkinson’s disease therapy. GNE-0877 is a highly potent and selective LRRK2 inhibitors.

In vitro: GNE-0877 showed significantly enhanced LRRK2 cellular potency (3 nM) and low turnover in human liver microsomes and hepatocytes with no evidence of glucuronidation. Invitrogen kinase-selectivity profiling (188 kinases) of GNE-0877 at 0.1 μM resulted in only four kinases showing greater than 50% inhibition and suggested that GNE-0877 is a highly selective LRRK2 inhibitor. Furthermore, GNE-0877 possessed a 212-fold biochemical-selectivity index over TTK (Ki = 150 nM) [1].

In vivo: GNE-0877 was evaluated for its ability to inhibit in vivo LRRK2 Ser1292 autophosphorylation using BAC transgenic mice expressing human LRRK2 protein with the G2019S Parkinson’s disease mutation. Using free-drug concentrations, robust concentration-dependent inhibition of Ser1292 autophosphorylation was observed for GNE-0877 [1].

Clinical trials: Currenlty no clinical data are available.
