Name: Summary of the probe development efforts to identify inhibitors of human diacylglycerol lipase, beta (DAGLB).
Description:
Endocannabinoids (ECs) represent a unique group of lipids that function as chemical messengers in the nervous system. To date, the two principle ECs identified in mammals are N-arachidonoyl-ethanolamine (anandamide) and 2-arachidonoyl-glycerol (2-AG). They have been implicated in various physiological and pathological functions including appetite, pain, sensation, memory, and addiction (1). Unlike traditional neurotransmitters, which are stored in vesicles, ECs are synthesized and released on demand, and then rapidly degraded to terminate signaling. Thus, the metabolic pathways that govern EC turnover are critical in determining the magnitude and duration of neuronal signaling events (2). Endocannabinoid biosynthesis, in contrast to degradation, is poorly understood. Recently, two serine hydrolases, DAGL-a and -B, were cloned and found to selectively cleave sn-1 acyl chains from diacylglycerols (DAG) to generate 2-AG in vitro (3). Their function in the nervous system was validated in vivo by the generation of DAGL-a and -B knock-out mice (4, 5). However, it is still unclear to what extent DAGL-a/B catalytic activity contributes to 2-AG-mediated signaling. The development of potent and selective inhibitors would offer a means to perturb DAGL-a/B activity in a selective, reversible, and temporally-controlled manner. Given the non-selective nature of current DAGL-a/B inhibitors (6), specific chemical probes would serve as invaluable tools to delineate DAGL-a/B function in 2-AG signaling networks of the brain.
