Clinical Studies

The Lineweaver-Burk summary shows that Huperzine A is a rival AChE inhibitor. After the sequential incubation with the temporary aspects of Huperzine A and the extraction of metabolites, AChE persists active, showing the reversible essence of the AChE-huperzine cooperation.

The faultless stereochemistry of Huperzine A is significant for AChE reserve (but not for all pharmacological influences); The malformed enantiomer Huperzine A (ent-1) is at least 50 times less efficient than the natural isomer.

This is solely expected in the circumstances of the X-ray crystallographic arrangement of the TcAChE network with Huperzine A, in which there is a strong interaction between the confidently charged amino group of Huperzine A and the aromatic rings of Trp84 and O Phe330 in the huperzine section.

Kozikowski and Tuckmantel transferred out extensive studies on the structural activity of Huperzine A and knew a unique analog with a higher affinity for AChE than its rival natural product.

The high affinity of Huperzine A for acetylcholinesterase helped the arrangement of a series of proposals for its use in the way of Alzheimer’s disease (AD) and as a pre-treatment upon organophosphate neurotoxic operators.


Although the exact etiology of AD remains distant, AD symptoms are affiliated with cholinergic deficits. Therefore, Huperzine A has been studied for the treatment of Alzheimer’s disease (AD). Huperzine A has been accepted in China for the operation of mild to moderate AD. It is widely used in the U.S. nutraceutical market.

The United Nations lists them as evidence of mass extinction. They exert their toxicity by immutable phosphorylation of AChE. The effects of this change pasture from minor signs, such as brevity of breath and hypersalivation, to severe symptoms, such as seizures and disqualification.

The current method of protection against the pretreatment of people with reversible AChE inhibitors. Pyridostigmine responds with AChE to form a carbamylated protein with a temporary balance.
