Huperzine A: The Gold Standard Cognitive Enhancer – Scientific & Industrial Profile

1. What is Huperzine A?
Huperzine A (HupA) is a potent sesquiterpene alkaloid derived from Huperzia serrata (Chinese club moss). Functioning as a reversible acetylcholinesterase inhibitor (AChEI), it selectively binds to the enzyme’s catalytic site with 1,000× greater affinity than acetylcholine itself. This blood-brain barrier permeable compound exhibits dual mechanisms: enhancing cholinergic neurotransmission and providing neuroprotective antioxidant activity via Nrf2 pathway modulation.
