生物活性:
Amantadine (1-Adamantanamine) sulfate is an orally avtive and potent antiviral agent with activity against influenza A viruses. Amantadine sulfate inhibits several ion channels such as NMDA and M2, and also inhibits Coronavirus ion channels. Amantadine sulfate also has anti-orthopoxvirus and anticancer activity. Amantadine sulfate can be used for Parkinson's disease, postoperative cognitive dysfunction (POCD) and COVID-19 research.

体内研究:
Amantadine sulfate (25 mg/kg, IP, once daily for 3 days) inhibits surgery induced neuroinflammation and learning and memory impairment.Animal Model:Fischer 344 rats (Four-month old, male, 290-330 g, 15 rats each group)
Dosage:25 mg/kg
Administration:IP, once daily for 3 days (the first dose at 15 min before surgery)
Result:Inhibited surgery induced neuroinflammation and learning and memory impairment, increased GDNF (glial cell line-derived neurotrophic factor) that was co-localized with glial fibrillary acidic protein (an astrocytic marker) in the hippocampus.

体外研究:
Amantadine sulfate (0-500 μM, 26 h) inhibits SARS-CoV-2 replication, with IC50 concentrations between 83 and 119 μM.Amantadine sulfate (0-100 μg/mL, 24-72 h) markedly inhibits the proliferation of HepG2 and SMMC?7721 cells. Amantadine sulfate (0-75 μg/mL, 48 h) arrests the cell cycle at the G0/G1 phase and induces apoptosis.Amantadine sulfate (0-75 μg/mL, 48 h) reduces the levels of the cell cycle?related genes and proteins (cyclin D1, cyclin E and CDK2), reduces Bcl-2 and increases the Bax protein and mRNA levels.
