Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) from vertebrates, other than their predominant acylcholine hydrolase (esterase) activity, display a genuine aryl acylamidase activity (AAA) capable of hydrolyzing the synthetic substrate o-nitroacetanilide to o-nitroaniline. This AAA activ
The present study represents the first comprehensive investigation of the effect of huperzine A (HUP-A), a new cholinesterase inhibitor (ChEI) isolated from a Lycopodium species, upon acetylcholinesterase (AChE) activity, acetylcholine (ACh) levels and release, and cholinergic receptors in rat brain
## Abstract LβHuperzineβA (HupβA), a natural cholinesterase inhibitor (ChEI) derived from the Chinese herb Huperzia serrata, was administered systemically (i.p.) or locally through the microdialysis probe into the rat cortex. Systemic HupβA significantly increased acetylcholine (ACh) levels above b
