Name: Late stage assay provider results from the probe development effort to identify inhibitors of diacylglycerol lipase, beta (DAGLb): fluorescence-based biochemical gel-based competitive Activity-Based Protein Profiling (ABPP) inhibition of mouse liver ABHD6 in vivo.

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.

Protocol
Assay Overview:

The purpose of this assay is to determine whether or not powder samples of test compounds are active in vivo. In this assay, test compounds are administered to mice. Mice are sacrificed, and their liver tissue harvested, homogenized, and the membrane fraction isolated and reacted with either the serine-hydrolase (SH)-specific activity-based probe fluorophosphonate-rhodamine (FP-Rh) or the activity-based probe HT-01. HT-01 bears a BODIPY fluorophore and urea triazole reactive group that selectively labels several serine hydrolases. This reagent is used in addition to FP-Rh to enhance visualization of select targets, which is otherwise obscured by other serine hydrolases upon SDS-PAGE separation/visualization. The reaction products are separated by SDS-PAGE and visualized in-gel using a flatbed fluorescence scanner. The percentage activity remaining is determined by measuring the integrated optical density of the bands. As designed, test compounds that act as inhibitors will prevent enzyme-probe interactions, thereby decreasing the proportion of bound fluorescent probe, giving lower fluorescence intensity in the band in the gel.

Protocol Summary:

Purpose-bred C57-black laboratory mice were administered test compound (20 or 5 mg/kg in 18:1:1 saline:PEG300:EtOH vehicle solution, i.p.) or vehicle only (n=1 per group). After 4 hours, mice were humanely sacrificed (anesthetized with isoflurane and decapitated) and liver tissue was removed and snap frozen in liquid nitrogen. Liver tissue was homogenized and the membrane fraction isolated by centrifugation (45 minutes, 100K x g) and adjusted to 1 mg/mL in DPBS. Aliquots (50 uL) were reacted with the activity-based probes HT-01 or FP-Rh (1 uL of a 50x stock in DMSO, 1 uM final concentration) for 30 minutes at 37 C. The reactions were quenched with an equal volume of 2x SDS-PAGE loading buffer (reducing), separated by SDS-PAGE and visualized by in-gel fluorescent scanning. The percentage activity remaining was determined by measuring the integrated optical density of test compound bands relative to vehicle bands. Anti-targets (unidentified 72 kDa SH and 65 kDa SH) with at least 50% inhibition for at least one test compound concentration are also quantified.

The percent inhibition for each compound was calculated as follows:

%_Inhibition = ( 1 - ( IOD_Test_Compound - Median_IOD_Low_Control ) / ( Median_IOD_High_Control - Median_IOD_Low_Control ) ) * 100

Where:

Test_Compound is defined as mouse liver membrane fraction treated with test compound.
High_Control is defined as mouse liver membrane fraction treated with DMSO only (no compound).
Low_Control is defined as background in a blank region of the gel.

PubChem Activity Outcome and Score:

The following applies to each panel in this assay:

Compounds with greater than or equal to 50% inhibition at 5 mg/kg were considered active. Compounds with less than 50% inhibition at 5 mg/kg were considered inactive.

Overall Outcome and Score:

Compounds active in both HT-01 and FP-Rh panels and inactive in either FP-Rh Anti-Target panel were considered active. Compounds inactive in one or both HT-01 and FP-Rh panels and/or active in either FP-Rh Anti-Target panel were considered inactive.

The PubChem Activity Score is assigned a value of 100 for active compounds, and 0 for inactive compounds.

The PubChem Activity Score range for active compounds is 100-100. There are no inactive compounds.
