(-)-Huperzine A-d4 hydrochloride
(-)-Huperzine A-d4 hydrochloride is deuterated labeled (-)-Huperzine A (HY-17387). (-)-Huperzine A (Huperzine A) is an alkaloid isolated from Huperzia serrata, with neuroprotective activity. (-)-Huperzine A is a potent, highly specific, reversible and blood-brain barrier penetrant inhibitor of acetylcholinesterase (AChE), with an IC50 of 82 nM. (-)-Huperzine A also is non-competitive antagonist of N-methyl-D-aspartate glutamate (NMDA) receptor. (-)-Huperzine A is developed for the research of neurodegenerative diseases, including Alzheimer’s disease.

Biological Activity
Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].
(-)-Huperzine A (1 μM; 2 hours) attenuates Aβ23-35 (20 μM)-induced neuronal injury[3].
(-)-Huperzine A (100 μM) reversibly inhibits the NMDA-induced current (IC50=126 μM) in whole-cell voltage-clamp recording in CA1 pyramidal neurons acutely dissociated from rat hippocampus[4].
