Biochem/physiol Actions

KT109 is a potent and selective inhibitor of Diacylglycerol lipase DAGLβ. Diacylglycerol lipases DAGLα and DAGLβ are serine hydrolases that biosynthesize the endocannabinoid 2-arachidonoylglycerol (2-AG). A lack of selective inhibitors has hampered study of these lipases. KT109 is a potent and selective DAGLβ inhibitor with an IC50 of 42 nM, ~60-fold selectivity for DAGLβ over DAGLα, and negligible activity against FAAH, MGLL and ABHD11, other key enzymes involved in endocannabinoid signaling. KT109 shows some inhibitory activity against PLA2G7 (IC50 = 1 μM) but no inhibitory activity against cytosolic phospholipase A2 (cPLA2 or PLA2G4A). The main off target inhibition against ABHD6 (IC50 = 16 nM) can be controlled for by use of the related compound, KT195, a potent (IC50 = 10 nM) and selective ABHD6 inhibitor with negligible activity against DAGLβ. KT109 disrupts the lipid network involved in macrophage inflammatory responses, lowering 2-AG, as well as arachidonic acid and eicosanoids, in mouse peritoneal macrophages.

The endocannabinoid 2-arachidonoylglycerol (2-AG) is biosynthesized by diacylglycerol lipases DAGLα and DAGLβ. Chemical probes to perturb DAGLs are needed to characterize endocannabinoid function in biological processes. Here we report a series of 1,2,3-triazole urea inhibitors, along with paired negative-control and

We have previously shown that 1,2,3-triazole ureas (1,2,3-TUs) act as versatile class of irreversible serine hydrolase inhibitors that can be tuned to create selective probes for diverse members of this large enzyme class, including diacylglycerol lipase-β (DAGLβ), a principal biosynthetic

Perturbation of calcium signaling that occurs during cell injury and disease, promotes cell death. In mouse lung fibroblasts A23187 triggered mitochondrial permeability transition pore (MPTP) formation, lactate dehydrogenase (LDH) release, and necrotic cell death that were blocked by cyclosporin A

The aim of the Cravatt research group is to understand the roles that mammalian enzymes play in physiological and pathological processes and to use this knowledge to identify novel therapeutic targets for the treatment of human disease. To achieve these goals, they develop and apply new technologies that bridge the fields of chemistry and biology, ascribing to the philosophy that the most significant biomedical problems require creative multidisciplinary approaches for their solution. The group's technological innovations address fundamental challenges in systems biology that are beyond the scope of contemporary methods. For instance, enzymes are tightly regulated by post-translational events in vivo, meaning that their activity may not correlate with expression as measured by standard genomic and proteomic approaches. Considering that it is an enzyme's activity, rather than abundance that ultimately dictates its role in cell physiology and pathology, the Cravatt group has introduced a set of proteomic technologies that directly measures this parameter. These activity-based protein profiling (ABPP) methods exploit the power of chemistry to engender new tools and assays for the global analysis of enzyme activities. The enzyme activity profiles generated by ABPP constitute unique molecular portraits of cells and tissues that illuminate how metabolic and signaling networks are regulated in vivo. Additionally, by evaluating enzymes based on functional properties rather than mere abundance, ABPP acquires high-content proteomic information that is enriched in novel markers and targets for the diagnosis and treatment of human disease.
