J-147 是一種特別有效的，具有口服活性的神經(jīng)保護(hù)劑，可增強(qiáng)認(rèn)知能力。J-147 可透過(guò)血腦屏障 (BBB)。J-147 抑制單胺氧化酶 B (MAO B) 和多巴胺轉(zhuǎn)運(yùn)體 (dopamine transporter)，EC50 分別為 1.88 μM 和 0.649 μM。J-147 有潛力用于阿爾茨海默氏癥 (AD) 的研究。 靶點(diǎn) MAO B; Dopamine transporter 體外研究 J-147 promotes HT22 and primary cell survival in a dose-dependent manner (EC 50 value range of 0.06-0.115 μM) . 體內(nèi)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 (t 1/2 ) 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.
