The glutamate receptors play a significant role in changing synaptic plasticity and play a significant role in memory and education. Two principal glutamate receptors, named after the agonists that fix to it, are AMPA and NMDA. (N.-Methyl-D-Aspartate).

Recently, NMDA receptors have accepted a lot of offerings, since their lavish excitation is related to several neurodegenerative illnesses, such as epilepsy and AD through Huperzine A. Various data suggest that the destruction of NMDA receptors by opponents dramatically attenuates these diseases.

An abundance of glutamate overstimulates the NMDA receptors and points to an entrance of calcium atoms. This calcium penetration is connected with a cascade of cellular degradation methods that result in the death of neuronal cells. Therefore, this excitotoxicity is supposed to add significantly to the sequence of various neurodegenerative diseases.

Huperzine A has been shown to inhibit glutamate-induced calcium mobilization in cell cultures39. vehicle crop control. Pretreating the cells with 100 nM huperzine A before adding glutamate reduced the mortality rate to 30%. There was also a correlation between the absorption of calcium ions and the concentration of Huperzine A.

Therefore, treatment with 10 m of glutamate developed the calcium ion concentration from 811 to 3 nM (mean values ​​for SEM, n for 99). However, this difference declined from 20% to 668 to 4 (mean values ​​for SEM, n for 102) after treatment with 100 nM Huperzine A.

Execution of cell cultures with 100 µg of glutamate also influenced important morphological differences, in particular the distribution of cell aggregates and the decrease of axonal processes.

Therefore, cells treated with approximately 10 m huperzine A had a survival rate of 85% corresponded to 35% in the restriction group. The Huperzine A receptor competitor -NMDA has been attached to its proximal merging to the binding sites of MK-801 (dizocilpine) and phencyclidine. This suggests that the activity of the Huperzine A – NMDA receptor opponent is free of its AChE inhibitory exercise.
