生物活性

J-147 is an exceptionally potent, orally active, neuroprotective agent for cognitive enhancement. J-147 can readily pass the blood brain barrier (BBB). J-147 can inhibit monoamine oxidase B (MAO B) and the dopamine transporter with EC50 values of 1.88 μM and 0.649 μM, respectively. J-147 has potential for the treatment of Alzheimer’s disease (AD).

体外研究

J-147 promotes HT22 and primary cell survival in a dose-dependent manner (EC50 value range of 0.06-0.115 μM) .

体内研究

J-147 (diet is prepared by the addition of J-147 at 200ppm; 6 months) enhances memory and dendritic spine number in old mice.
The half life (t1/2) of J-147 is calculated at 1.5 hrs in plasma and 2.5 hrs in brain ( per oral (PO) administration at a single dose of 20 mg/kg).

Animal Model: 24 male C57Bl/6 mice aged 24 months; using 8 month-old mice as controls
Dosage: 200 ppm
Administration: The diet was prepared by the addition of 200ppm; 6 months
Result: While both young and old animals recognized when an object was moved a large distance (135 degrees), a reduction in the recognition index (RI) in aged mice was observed when the object was moved a smaller distance of 45 degrees. The reduction in the RI was reversed upon treatment with J147.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
