GNE-0877 (GNE 0877; GNE0877) is a novel, highly potent and selective leucine-rich repeat kinase 2 (LRRK2) inhibitor with important biological activity. It inhibits LRRK2 with a Ki of 0.7 nM. 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).
| ln Vitro |
GNE0877 (1 μM; 10–30 min) exhibits good hepatocyte and human liver microsome cellular potency[1].

| ln Vivo |
The LRRK2 Ser1292 autophosphorylation is inhibited by GNE0877 (10 and 50 mg/kg; ip once)[1].

| Cell Assay |
Cell Viability Assay[1]
Cell Types: Human liver microsomes and hepatocytes Tested Concentrations: 1 μM Incubation Duration: 10, 20 and 30 min Experimental Results: Exibited low turnover and good in vitro stability in human liver microsomes and hepatocytes with no glucuronidation. |
| Animal Protocol |
Animal/Disease Models: BAC transgenic mice expressing human LRRK2 protein with the G2019S Parkinson's disease mutation[1]
Doses: 10 and 50 mg/kg Route of Administration: intraperitoneal (ip)injection; 10 and 50 mg/kg once Experimental Results: Tration-dependently inhibited Ser1292 autophosphorylation with an IC50 of 3 nM. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (6.13 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (6.13 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
