Notes: Huperzine B is an alkaloid originally isolated from H. serrata with neuroprotective activity.{65371} It selectively binds to acetylcholinesterase (AChE) over butyrylcholinesterase (BChE; IC50s = 8.2 and 157 µM, respectively).{65369} It is also an antagonist at the NMDA receptor (IC50 = 316.6 µM).{65370} Huperzine B (0.1-100 µM) increases the viability of PC12 cells in a model of hydrogen peroxide-induced cell injury.{65371} It increases glutathione peroxidase (GPX) and catalase (CAT) activities, and decreases malondialdehyde (MDA) levels, in PC12 cells in a model of hydrogen peroxide-induced cell injury when used at concentrations ranging from 10 to 100 µM.
