General description

Stearoyl ethanolamide, also called N-stearoylethanolamine (NSE) is present ubiquitously in all mammals. It exists in three isoforms when synthesized. It has therapeutic potential to modulate immune and inflammatory responses. It also possess antioxidative and membranoprotective functionality. NSE molecules pack in tail-to-tail fashion in lipid bilayer.

Application

Stearoyl ethanolamide (NSE) has been used as standard for quantifying in house synthesized NSE using thin layer chromatography.

Biochem/physiol Actions

Most abundant fatty acid ethanolamide produced by PLD hydrolysis of cell membrane phospholipids.

The effects of saturated long-chain (C: 16-22) N-acylethanolamines and a series of saturated fatty acids with the same length of carbon chains were investigated on depolarization-induced (45)Ca(2+) fluxes mediated by voltage-dependent Ca(2+) channels in transverse tubule membrane vesicles from rabbit

Given the recent demonstration that oleoylethanolamide (OEA), a cannabinoid receptor-inactive N-acylethanolamine, decreases food intake by activating the nuclear receptor PPARalpha (peroxisome proliferator-activated receptor alpha) in the periphery, we here evaluated the effects of both saturated and unsaturated C18 N-acylethanolamides (C18:0;

N-acylethanolamines, which include the endocannabinoid anandamide and the cannabinoid receptor-inactive saturated compounds N-palmitoyl ethanolamine and N-stearoyl ethanolamine, are ethanolamines of long-chain fatty acids degraded by fatty acid amide hydrolase (FAAH) known to accumulate in degenerating tissues and cells.

Stearoylethanolamide (SEA) is present in human, rat and mouse brain in amounts comparable with those of the endocannabinoid anandamide (arachidonoylethanolamide; AEA). Yet, the biological activity of SEA has never been investigated. We synthesized unlabelled and radiolabelled SEA to investigate its
