Synthesis, Molecular Modeling and Biological Evaluation of Metabolically Stable Analogues of the Endogenous Fatty Acid Amide Palmitoylethanolamide
Laboratory studyHumansOther animalsWith RePEA (a PEA analogue, tested alone and against PEA)
This study tested palmitoylethanolamide together with RePEA (a PEA analogue, tested alone and against PEA). Its results cannot be assigned to palmitoylethanolamide alone. More combination studies.
- Design
- Laboratory study
- Subjects
- Computer modelling; membrane samples containing FAAH; murine N9 microglial cells and human PMA-THP-1 cells stimulated with LPS
- Dose used in the study
- Not stated in the abstract
- Duration
- Not stated in the abstract
- What was measured
- Predicted and measured resistance of PEA analogues to FAAH hydrolysis (by 1H-NMR); inhibition of LPS-induced cytokine release in cultured cells
What the authors reported
The study found:
- Modelling picked RePEA as the most accessible and FAAH-resistant analogue.
- NMR showed RePEA was not broken down by FAAH, unlike PEA.
- RePEA kept PEA's ability to inhibit LPS-induced cytokine release in both mouse microglia and human THP-1 cells.
Limits of this study
A chemistry and cell-culture study; it cannot show effect in people or animals treated in practice. The authors declare no conflict of interest.
