A sesquiterpene alkaloid isolated from a club moss Huperzia serrata that has been shown to exhibit neuroprotective activity. It is also an effective inhibitor of acetylcholinesterase and has attracted interest as a therapeutic candidate for Alzheimer's disease.
ABCB1A gene mutant form affects the transport of and results in increased abundance of huperzine A Elacridar inhibits the reaction [ABCB1 protein results in increased transport of huperzine A]; Verapamil inhibits the reaction [ABCB1 protein results in increased transport of huperzine A]
huperzine A results in decreased activity of ACHE protein [huperzine A co-treated with tetramethylpyrazine] results in decreased activity of ACHE protein ALB protein affects the reaction [huperzine A results in decreased activity of ACHE protein]; huperzine A inhibits the reaction [ACHE protein results in increased hydrolysis of Butyrylthiocholine] huperzine A binds to and results in decreased activity of ACHE protein
