Biological Activity

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.

5-Phenyluracil

5-Phenyluracil is a pyrimidine derivative, a class of heterocyclic aromatic organic compounds crucial in biochemistry. It serves as a synthetic nucleoside analogue, meaning it mimics the structure of naturally occurring nucleosides like uridine. This structural similarity allows it to participate in biochemical reactions, often interfering with normal cellular processes, making it a valuable tool in studying nucleic acid metabolism and developing antiviral and anticancer agents.

7-Deoxyloganin

7-Deoxyloganin is a biosynthetic precursor of Loganin. 7-Deoxyloganin undergoes hydroxylation catalyzed by 7-deoxyloganin 7-hydroxylase, a cytochrome P450-dependent monooxygenase, to produce Loganin.
