Product Description

GNE-9605 (GNE 9605; GNE9605) is a novel, brain-penetrant, highly potent and selective leucine-rich repeat kinase 2 (LRRK2) inhibitor with anti-PD (Parkinson's disease) activity. It inhibits LRRK2 with a Ki and an IC50 of 2 nM and 19 nM, respectively. In human hepatocytes and liver microsomes, GNE-9605 exhibited excellent human metabolic stability.

Biological Activity I Assay Protocols (From Reference)
ln Vitro

In vitro activity: GNE-9605 is highly potent against LRRK2 in both biochemical (Ki = 2.0 nM) and cellular (IC50 = 19 nM) assays. In vitro human MDR1 permeability data, GNE-9605 exhibits excellent brain penetration in higher species.


Kinase Assay: In rat pharmacokinetic (PK) studies, GNE-9605 exhibited excellent oral bioavailability of 90% and total plasma clearance of 26 mL/min/kg. In bacterial artificial chromosome (BAC) transgenic mice expressing human G2019S LRRK2 protein with the Parkinson’s disease mutation, GNE-9605 (10 or 50 mg/kg) inhibited LRRK2 Ser1292 autophosphorylation with IC50 value of 20 nM in a concentration dependent way. In cynomolgus monkey PK studies, GNE-9605 exhibited excellent brain penetration.


Cell Assay: GNE-9605 retained excellent predicted human metabolic stability when assayed in human liver microsomes and hepatocytes. In addition, no reversible or time-dependent inhibition of any of the major CYP isoforms was observed. The demonstrated metabolic stability, brain penetration across multiple species, and selectivity of these inhibitors support their use in preclinical efficacy and safety studies.

ln Vivo
LRRK2 Ser1292 autophosphorylation is inhibited by GNE-9605 (10 and 50 mg/kg; ip; once) in BAC transgenic mice that express human LRRK2 protein[1]. In the biochemical assay, GNE-9605 (1 mg/kg, po; 0.5 mg/kg, iv; once) exhibits LRRK2 Ki of 2 nM and a cellular IC50 of 19 nM. GNE-9605 has exceptional oral bioavailability and total plasma clearance [1].

*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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
g/mol

Molecular Weight Calculator allows you to calculate the molar mass and elemental composition of a compound, as detailed below:

Note: Chemical formula is case sensitive: C12H18N3O4  c12h18n3o4
Instructions to calculate molar mass (molecular weight) of a chemical compound:
  • To calculate molar mass of a chemical compound, please enter the chemical/molecular formula and click the “Calculate’ button.
Definitions of molecular mass, molecular weight, molar mass and molar weight:
  • Molecular mass (or molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
  • Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
