Description of Docosahexaenoyl Ethanolamide-d4

Docosahexaenoyl ethanolamide-d4 contains four deuterium atoms at the 1, 1', 2, and 2' positions. It is intended for use as an internal standard for the quantification of docosahexaenoyl ethanolamide by GC- or LC-mass spectrometry (MS). Docosahexaenoic Acid (DHA) is an essential fatty acid and the most abundant ω-3 fatty acid in neural tissues, especially in the retina and brain. Docosahexaenoyl ethanolamide (DHEA) is the ethanolamine amide of DHA that has been detected in both brain and retina at concentrations similar to those for arachidonoyl ethanolamide (AEA).1,2 A 9.5 fold increase of DHEA was observed in brain lipid extracts from piglets fed a diet supplemented with DHA compared to a control diet without DHA.3 DHEA binds to the rat brain CB1 receptor with a Ki value of 324 nM, which is approximately 10-fold higher than the Ki value for AEA.4 DHEA inhibits shaker-related voltage-gated potassium channels in brain slightly better than AEA, with an IC50 value of 1.5 µM.5

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
