N-Arachidonoyl-L-serine
Based on 1 Customer Validation
N-Arachidonoyl-L-serine (ARA-S) is an endocannabinoid. N-Arachidonoyl-L-serine induces phosphorylation of Akt and MAPK in endothelial cells. N-Arachidonoyl-L-serine also induces endothelium-dependent vasodilation in isolated rat mesenteric and abdominal aortas. N-Arachidonoyl-L-serine exhibits neuroprotective effects after traumatic brain injury by reducing apoptosis. N-Arachidonoyl-L-serine promotes the opening of KV7.1/KCNE1 channels in mammalian cells and shortens the action potential duration in cardiomyocytes. N-Arachidonoyl-L-serine may be used in research on cardiovascular and cerebrovascular diseases and neurological disorders.
