What is Huperzine A High?

Huperzine A High is an all-natural plant alkaloid extracted from the traditional Chinese medication Huperzine genus Melaleuca. It is a powerful, relatively easy to fix in addition to highly critical second-generation acetylcholinesterase avoidance. Its look is light yellow to white crystalline powder, easily soluble in chloroform, soluble in methanol in addition to ethanol, slightly soluble in water, has high fat solubility, tiny particle, can go through the blood-brain challenge well, and also after getting in the central nerves, it is much more dispersed in the frontal wattle, Temporal lobe, hippocampus and also various other mind areas that are very carefully related to finding out along with memory have a strong inhibitory effect on acetylcholinesterase (DISCOMFORT) at minimized dosages,which substantially raises the material of acetylcholine (Ach) in the synaptic void in the distribution location, so regarding improve the excitatory transmission of nerve cells, enhance the excitatory result of discovering and also memory brain regions, as well as play a role in boosting cognitive function, improving memory retention and also advertising memory recreation. It is presently one of the most effective drug for the therapy of Alzheimer’s condition (senile dementia) developed in China.

Huperzine A High Indications

Huperzine A High is a relatively easy to fix and also potent cholinesterase prevention, stronger than physostigmine, neostigmine and Tacrine. For myasthenia gravis, the efficient price is 99%.
Professional trials have actually shown that this item appropriates for benign memory problems, and can improve the capability of clients to point to memory, associative understanding, picture recall, acknowledgment of worthless graphics as well as portrait recall, as well as it can also improve the learning and memory of normal people; this product is effective for mental deterioration patients. It can additionally boost the memory impairment brought on by brain natural condition.
Clinically, huperzine A can be applied to the treatment of the following signs:
1. Huperzine A High is utilized to deal with as well as improve amnesia in middle-aged as well as senior individuals, as well as boost associative recall function; it is utilized for memory loss brought on by extreme use the brain, and also improves knowing and also job effectiveness;
2. Used for amnesia related to neurasthenia;
3. Huperzine A High is used for memory loss triggered by cerebrovascular conditions;
4. It is utilized to boost the memory of Alzheimer’s condition, as well as it has noticeable alleviative effect on enhancing and also bring back the cognition, memory function and also unusual emotional behavior of individuals;
5. Huperzine A High is utilized to treat myasthenia gravis;
6. Huperzine A can improve organization problems, cognitive disability as well as memory loss associated with schizophrenia;
7. It can improve the memory loss related to different mind conditions and physical diseases.

Neuroprotective Effects of Huperzine A High

1 Anti-inflammatory effect and protection of rat neural stem cells
The ratio of pro-apoptotic and anti-apoptotic proteins in the Bcl-2 protein family determines whether cells undergo apoptosis after being stimulated by apoptotic signals. When the Bcl-2/Bax value decreases, Bax forms a homodimer to induce cell apoptosis; when the Bcl-2/Bax value increases, Bax and Bcl-2 form a heterodimer to achieve Bcl-2 inhibition of cell death. Apoptotic function. Zhu Ning et al. found in rat experiments that under the stimulation of Aβ1-42-mediated inflammatory response in neural stem cells, the expression levels of Bcl-2 and Bax were the highest in each group, while the Bcl-2/Bax value was the highest in each group. lowest. After Hup A pretreated microglia, liquid chip detection showed that the secretion of inflammatory factors was reduced, and at the same time, the Bcl-2/Bax value was significantly higher than that of the Aβ group, which inhibited the apoptosis of neural stem cells. The results of Western blotting and flow cytometry both suggested that Hup A could inhibit the apoptosis of neural stem cells.

2 Against the neurotoxicity of organophosphates
The main mechanism of Huperzine A High against organophosphate poisoning is: the reversible combination of Hup A with acetylcholinesterase in advance of administration, thus preventing the irreversible combination of organophosphorus compounds and acetylcholinesterase. Compared with other reversible cholinesterase inhibitors such as pyridostigmine bromide, Hup A has two advantages: On the one hand, Huperzine A High can pass through the blood-brain barrier, thereby protecting the acetylcholinesterase in the brain . On the other hand, butyrylcholinesterase and carboxylesterase may be endogenous organophosphate scavengers, Hup A can selectively inhibit plasma erythrocyte acetylcholinesterase, but has no inhibitory effect on butyrylcholinesterase, So the selectivity of Hup A is helpful for the prevention of organophosphate poisoning.

3 Fight against glutamate toxicity
Glutamate is an agonist of N-methyl-D-aspartate (NMDA) receptors. NMDA receptors are stimulated to increase the influx of calcium ions into neurons, and excessive calcium ions can lead to cell death . Huperzine A High can reduce the toxicity of glutamate to nerve cells and increase the cell survival rate, especially for mature neuron cells, because there are more NMDA receptors in mature neuron cells. The mechanism of anti-glutamate may be that after the NMDA receptor is stimulated, Hup A blocks somewhere downstream of its signal transduction channel, thereby preventing cell death caused by glutamate. In addition, the protective effect of Hup A on nerve cells may also be Involvement mediated by glutamate receptors.

4 Fights Oxidative Stress
Huperzine A High protects neuronal cells against the toxicity of β-amyloid production and increases the production of superoxide dismutase (SOD). Rat primary cortical cells cultured in vitro were incubated under the condition of Aβ25-35 (the 25th to 35th amino acid residues of β-amyloid protein fragments), and the apoptosis of the cells could be observed, the viability of the cells decreased significantly, and the morphology of neurons Alteration and its DNA fragmentation. Pre-administration of Hup A can significantly improve cell survival and prevent nuclear fragmentation. The mechanism is that Hup A inhibits the formation of reactive oxygen species (ROS reactive oxygen species) and the activity of caspase-3 enzyme.

5 Inhibition of neurotoxicity of NO
Studies have shown that NO can inhibit the growth of human neuroblastoma SK-N-SH line cells and induce cell apoptosis. Huperzine A High, ginkgolides A and B can block the apoptosis and growth inhibition of sodium nitroprusside (NO donor) on SK-N-SH cells. In addition, Hup A and ginkgolides A and B can also inhibit the production of NO in mouse glial cells and the production of NO in human and mouse astrocytes.

Production Method of Huperzine A High

CN1781907A discloses a kind of production method of high-purity huperzine A, comprises the steps:

(1) The pretreatment adopts conventional methods to fully soak the dry powder of Melaleuca tower with 1.2% tartaric acid solution, adjust the pH value of the solution to weak alkalinity with ammonia water, repeatedly extract with chloroform, concentrate and evaporate the extract to dryness, and obtain huperzine A crude product; the crude product can be used for sample injection after being dissolved with an appropriate amount of stationary phase solution;

(2) Preparative high-speed countercurrent chromatography separates and selects a solvent system, and adopts a preparative high-speed countercurrent chromatographic system for separation;

(3) Aftertreatment Concentrate the collected solution of huperzine A under reduced pressure and evaporate to dryness to obtain an off-white solid, then dissolve it with an appropriate amount of acetone, crystallize at 0-10°C, and dry the crystal to obtain a white powdery solid That is the finished product.
