MedKoo Cat#: 462227 | Name: LEI401
Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

LEI401 is an NAPE-PLD inhibitor that modulates emotional behavior in mice. LEI-401 reduced NAE levels in neuroblastoma cells and in the brain of freely moving mice, but not in NAPE-PLD KO cells and mice, respectively. LEI-401 activated the hypothalamus–pituitary–adrenal axis and impaired fear extinction, thereby emulating the effect of a cannabinoid CB1 receptor antagonist, which could be reversed by a fatty acid amide hydrolase inhibitor.

Biological target:
LEI-401 is a first-in-class, selective, and CNS-active NAPE-PLD (N-acylphosphatidylethanolamine phospholipase D) inhibitor, with an IC50 of 27 nM. LEI-401 modulates emotional behavior in mice.
In vitro activity:
Using a high-throughput screen, chemical proteomics and targeted lipidomics, this study reports here the discovery and characterization of LEI-401 as a CNS-active N-acylphosphatidylethanolamine phospholipase D (NAPE-PLD) inhibitor. LEI-401 reduced NAE levels in neuroblastoma cells and in the brain of freely moving mice, but not in NAPE-PLD KO cells and mice, respectively. LEI-401 activated the hypothalamus-pituitary-adrenal axis and impaired fear extinction, thereby emulating the effect of a cannabinoid CB1 receptor antagonist, which could be reversed by a fatty acid amide hydrolase inhibitor.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
