More Info

Mutations in PARK8/LRRK2 are the most common genetic cause of Parkinson's disease. Inhibition of LRRK2 kinase activity has neuroprotective benefits, and provides a means of addressing the underlying biochemical cause of Parkinson's disease for the first time. Initial attempts to develop LRRK2 inhibitors were largely unsuccessful and highlight shortcomings intrinsic to traditional, high throughput screening methods of lead discovery.

Biological target:

GNE-7915 is an inhibitor of LRRK2 with an IC50 of 9 nM.

In vitro activity:

Whether LRRK2 G2019S-induced mtDNA damage is kinase dependent was investigated. A pretreatment paradigm in which primary midbrain neuronal cultures were treated with vehicle or GNE-7915 for 24 h and then transduced with either GFP or LRRK2 G2019S for 24 h was used. Pretreatment with GNE-7915 was able to prevent LRRK2 G2019S-induced mtDNA damage (Fig. 4A). Mitochondrial DNA copy number was unaffected by treatments (Fig. 4B). Importantly, treatment of GNE-7915 by itself did not alter mtDNA damage levels or copy number (Supplementary Material, Fig. S2). It was also confirmed that treatment with GNE-7915 reduced levels of LRRK2 pSer935, as these sites may be modulated indirectly by LRRK2 kinase activity and dephosphorylation occurs with LRRK2 kinase inhibitor exposure (Supplementary Material, Fig. S3).

In vivo activity:

The effects of LRRK2 inhibitor GNE-7915 on R1441G Tg mice were examined to see whether GNE-7915 could alleviate DA (dopamine) transmission deficits. When treated with 1 μM GNE-7915 for 2 h, a significant increase of PPR (pair-pulse ratio) was observed (PPR/5s, control: 0.45 ± 0.01, treated: 0.48 ± 0.01, n = 10, P < 0.05; PPR/10s, control: 0.61 ± 0.005, treated: 0.66 ± 0.008, n = 10, P < 0.01; PPR/20s, control: 0.80 ± 0.015, treated: 0.84 ± 0.002, n = 10, P < 0.001, Figure 6). Single-pulse-evoked DA release was also enhanced (control: 1.93 ± 0.15 μM, n = 10; treated: 2.17 ± 0.19 μM, n = 10, P < 0.05, Figure 6).

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
