Background

Huperzine B is an alkaloid originally isolated from H. serrata with neuroprotective activity.1 It selectively binds to acetylcholinesterase (AChE) over butyrylcholinesterase (BChE; IC50s = 8.2 and 157 ?M, respectively).2 It is also an antagonist at the NMDA receptor (IC50 = 316.6 ?M).3 Huperzine B (0.1-100 ?M) increases the viability of PC12 cells in a model of hydrogen peroxide-induced cell injury.1 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 ?M.
