Product Description

Atabecestat (formerly known as JNJ-54861911) is a novel potent, oral, and brain-penetrant BACE1 inhibitor that inhibits β-site amyloid precursor protein cleaving enzyme 1 (BACE1), an enzyme up-regulated in Alzheimer's disease. β-Secretase enzyme (BACE) inhibition has been proposed as a priority treatment mechanism for Alzheimer's disease (AD), but treatment initiation may need to be very early. JNJ-54861911 was found to inhibit BACE1 with approximately 2,600 nM affinity to 1 nM affinity. JNJ-54861911 was well-tolerated, adverse events were uncommon and unrelated to JNJ-54861911. JNJ-54861911 showed dose-proportional CSF and plasma pharmacokinetic profiles.

Biological Activity I Assay Protocols (From Reference)
ln Vitro

In vitro activity: Atabecestat (formerly known as JNJ-54861911) is a novel potent, oral, and brain-penetrant inhibitor of β-site amyloid precursor protein cleaving enzyme 1 (BACE1), which is an enzyme that is up-regulated in Alzheimer’s disease. β-Secretase enzyme (BACE) inhibition has been proposed as a priority treatment mechanism for Alzheimers disease (AD), but treatment initiation may need to be very early. JNJ-54861911 was found to inhibit BACE1 with approximately 2,600 nM affinity to 1 nM affinity. JNJ-54861911 was well-tolerated, adverse events were uncommon and unrelated to JNJ-54861911. JNJ-54861911 showed dose-proportional CSF and plasma pharmacokinetic profiles.


Kinase Assay: JNJ-54861911 inhibited BACE1 with IC50 of 2,600 nM to 1 nM.

ln Vivo
Mice treated with atabecestat (100 and 300 mg/kg; po once daily for 3 days) have lower levels of human Aβ[2]. When APPPS1 mice are treated with 3D6, atabecestat (300 mg/kg; po once) prevents the vascular abnormalities from getting worse[2].
Animal Protocol
Animal/Disease Models: 5weeks old APPPS1 mice[2]
Doses: 100 and 300 mg/kg
Route of Administration: po (oral gavage); 100 and 300 mg/kg; one time/day for 3 days
Experimental Results: decreased the level of human Aβ1- 40 and Aβ1-42 levels in the brain of APPPS1 mice at a dose of 300 mg/kg and resulted in less reduction of human Aβ levels at 24 h with a dose of 100 mg/kg.

Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.

 (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.

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
