FAAH inhibitor

URB754 is a potent and noncompetitive inhibitor of monoacylglycerol lipase (MAGL), exhibiting an IC50 value of 200 nM for the recombinant rat brain enzyme. However, it does not inhibit human recombinant, rat brain, or mouse brain MAGL at concentrations up to 100 μM. There is evidence that the MAGL inhibitory activity of URB754 may be attributed to the impurity bis(methylthio)mercurane (IC50 = 11.9 nM for rat recombinant MAGL) that is found in commercial preparations. URB754 inhibits rat brain fatty acyl amide hydrolase (FAAH) with an IC50 value of 32 μM and binds weakly to the rat central cannabinoid (CB1) receptor with an IC50 value of 3.8 μM. It does not inhibit COX-1 or COX-2 at concentrations up to 100 μM. Inhibition of MAGL hydrolysis of 2-arachidonoyl glycerol (2-AG) is associated with enhanced stress-induced analgesia and may represent a novel drug target in pain and stress management.

The endocannabinoids, 2-arachidonoyl glycerol (2-AG) and arachidonoyl ethanolamide (AEA), are biologically active lipids that regulate diverse neurological and metabolic functions by activating the cannabinoid receptors, central cannabinoid (CB1) and peripheral cannabinoid (CB2). Monoacylglycerol lipase (MAGL) and fatty acid amide hydrolase (FAAH) hydrolyze 2-AG and AEA, respectively, thus terminating their biological function. IDFP is an organophosphorus compound that dually inhibits MAGL and FAAH with IC50 values of 0.8 and 3 nM, respectively. At 10 mg/kg, IDFP elevates brain levels of 2-AG and AEA more than 10-fold, and decreases levels of arachidonic acid by a similar magnitude.

Anandamide (arachidonoyl ethanolamide; AEA) is an endogenous lipid with cannabinergic activity; along with 2-arachidonoyl glycerol, it forms part of the endocannabinoid system. AEA undergoes reuptake into neurons by a facilitated process. Controversy exists as to whether there is a specific AEA transporter, or instead the uptake process is simply driven by hydrolysis of AEA by intracellular fatty acyl amide hydrolase (FAAH). CAY10412 is an analog of AEA that has no intrinsic binding affinity for either CB1 or CB2 receptors. It is a potent inhibitor of AEA reuptake in U937 lymphoma cells, with an IC50 of 3 μM. CAY10412 could be a useful tool for distinguishing the competing transporter theories. The pharmacology of CAY10412 is largely unexplored; it may enhance endocannabinoid signalling by augmenting endocannabinoid concentrations.

Arachidonoyl 2-chloroethylamide (ACEA) is a potent and selective cannabinoid (CB) receptor 1 agonist with Ki values of 1.4 and >2,000 nM for CB1 and CB2 receptors, respectively. In whole animal experiments, ACEA induces hypothermia in mice with the same efficacy as arachidonoyl ethanolamide , in spite of its higher affinity for the CB1 receptor. These data have been interpreted to indicate that ACEA may be a substrate for fatty acid amide hydrolase (FAAH), and thus only transiently available in whole animal experiments.

N-(1-(3,4-Dihydroxyphenyl)propan-2-yl)oleamide binds to the cannabinoid 1 (CB1) receptor with a Ki value of 365 nM in a radioligand binding assay using rat brain homogenate. It has an EC50 value of 698 nM for the peroxisome proliferator-activated receptor α (PPARα) in a luciferase reporter assay and, in rats, it decreases food intake. It does not inhibit fatty acid amide hydrolase (FAAH).

Orlistat-d3 is intended for use as an internal standard for the quantification of orlistat by GC- or LC-MS. Orlistat is a digestive lipase inhibitor. It inhibits diacylglycerol lipase α (DAGLα), DAGLβ, α β-hydrolase domain-containing protein 12 (ABHD12), ABHD16A, and platelet-activating factor acetylhydrolase (PAF-AH; IC50s = 0.06, 0.1, 0.08, 0.03, and 0.05 µM, respectively), as well as pancreatic lipase and hormone-sensitive lipase (IC50s = 0.65 and 2.1 µg ml, respectively) but does not inhibit fatty acid amide hydrolase (FAAH) or KIAA1363 (IC50s = >100 µM for both). Orlistat decreases ionomycin-induced production of the endocannabinoid 2-arachidonoyl glycerol (2-AG) in N18TG2 murine neuroblastoma cells when used at a concentration of 1 µM. It also inhibits fatty acid synthase (FASN; Kiapp = ~0.1 µM for the human enzyme) and the proliferation of PC3 prostate cancer cells in a concentration-dependent manner.
