Neuroprotective Effects of Cannabispirenone A against NMDA‐Induced Excitotoxicity in Differentiated N2a Cells

open access: yesOxidative Medicine and Cellular Longevity, Volume 2024, Issue 1, 2024.
The endocannabinoid system is found throughout the central nervous system, and its cannabinoids receptor 1 is critical in preventing neurotoxicity caused by N‐methyl‐D‐aspartate receptor activation (NMDARs). The activity of NMDARs places demands on endogenous cannabinoids to regulate their calcium currents.
