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 the IC50 values of powder samples of test compounds for anti-target ABHD6 inhibition in a complex proteome lysate. In this assay, a fluorescently-labeled activity-based probe, HT-01, which selectively labels several serine hydrolases including ABHD6, is used to label the proteins in the presence of test compounds. 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 (IOD) of the bands. As designed, test compounds that act as ABHD6 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:
Membrane proteome of Neuro-2A murine neuroblastoma cells (25 uL of 1 mg/mL) in Dulbecco's PBS (DPBS) was treated with test compound (0.5 uL of a 50x stock in DMSO) or DMSO (0.5 uL) for 30 minutes at 37 C. The activity-based probe HT-01 (0.5 uL of a 50x stock in DMSO; 1 uM final concentration) was added, and the reaction was incubated for 30 minutes at 37 C, 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 for anti-target ABHD6 was determined by measuring the integrated optical density of the individual protein bands relative to the DMSO-only (no compound) control. IC50 values were determined from dose-response curves from three replicates at each inhibitor concentration (6-point 1:5 dilution series from 2 uM to 0.00064 uM [2000 nM to 0.64 nM]).
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 proteome treated with test compound.
High_Control is defined as proteome treated with DMSO only (no compound).
Low_Control is defined as background in a blank region of the gel.
Percent inhibition was plotted against the log of the compound concentration. A three parameter equation describing a sigmoidal dose-response curve was then fitted using GraphPad Prism (GraphPad Software Inc). The software-generated IC50 values are reported. In the event that Prism did not adequately fit the data, the IC50 is manually determined and reported as an approximate value.
PubChem Activity Outcome and Score:
Compounds with an IC50 less than or equal to 0.005 uM were considered active. Compounds with an IC50 greater than 0.005 uM were considered inactive.
Activity score was then ranked by the potency, with the most potent compounds assigned the highest activity scores.
The PubChem Activity Score range for active compounds is 100-100. There are no inactive compounds.
