ABHD11, a new diacylglycerol lipase involved in weight gain regulation

Firefly luciferin methyl ester illuminates the activity of multiple serine hydrolases

Firefly luciferin methyl ester is hydrolyzed by monoacylglycerol lipase MAGL, amidase FAAH, poorly-characterized hydrolase ABHD11, and hydrolases known for S-depalmitoylation (LYPLA1/2), not just esterase CES1. This enables activity-based bioluminescent assays for serine hydrolases and suggests that the 'esterase activity' responsible for hydrolyzing ester prodrugs is more diverse than previously supposed.

α/β-Hydrolase Domain (ABHD) Inhibitors as New Potential Therapeutic Options against Lipid-Related Diseases

Much of the experimental evidence in the literature has linked altered lipid metabolism to severe diseases such as cancer, obesity, cardiovascular pathologies, diabetes, and neurodegenerative diseases. Therefore, targeting key effectors of the dysregulated lipid metabolism may represent an effective strategy to counteract these pathological conditions. In this context, α/β-hydrolase domain (ABHD) enzymes represent an important and diversified family of proteins, which are involved in the complex environment of lipid signaling, metabolism, and regulation. Moreover, some members of the ABHD family play an important role in the endocannabinoid system, being designated to terminate the signaling of the key endocannabinoid regulator 2-arachidonoylglycerol. This Perspective summarizes the research progress in the development of ABHD inhibitors and modulators: design strategies, structure-activity relationships, action mechanisms, and biological studies of the main ABHD ligands will be highlighted.
