DAGLβ Inhibitor

DO34 is a selective DAGL inhibitor, with an IC₅₀ of 6 nM for DAGLα conversion of SAG to 2-AG. DO34 blocks de novo 2-AG synthesis, and suppresses tonic CB₁ receptor activation. DO34 blocks depolarization-induced suppression of excitation and inhibition in the cerebellum and hippocampus. DO34 regulates feeding behavior and locomotor activity in mice. DO34 abolishes AM251-mediated enhancement of parallel fiber-evoked excitatory postsynaptic currents in cerebellar slices from MAGL global knockout mice. DO34 can be used for the research of energy balance disorder and neuroinflammation.

A1480LS is a peripherally restricted, orally active covalent and irreversible inhibitor of DAGLα and DAGLβ, with IC₅₀ values of 6 nM and 4 nM against human targets, respectively, and IC₅₀ values ≤15 nM across mouse, rat, dog, monkey and human systems. A1480LS reduces the levels of 2-arachidonoylglycerol, arachidonic acid, and cyclooxygenase- and lipoxygenase-derived eicosanoids. A1480LS inhibits injury-induced production of 2-arachidonoylglycerol and arachidonic acid in the peripheral sciatic nerve, and suppresses the responses of high-threshold and wide-dynamic-range-like dorsal horn neurons to mechanical stimulation. A1480LS alleviates pain behaviors in rat models of inflammatory pain, neuropathic pain and chemotherapy-induced peripheral neuropathy.

(R)-KT109 is a peripherally restricted serine hydrolase inhibitor that cannot cross the blood-brain barrier. (R)-KT109 irreversibly inhibits ABHD6, DAGLα and DAGLβ via carbamoylation of the active-site serine. (R)-KT109 exerts selective inhibitory effects on serine hydrolases in mouse brains, with pIC₅₀ values of 8.6, 9.1 and 8.2 against human ABHD6, DAGLα and DAGLβ, respectively. (R)-KT109 effectively reduces the levels of 2-arachidonoylglycerol, arachidonic acid, eicosanoids and TNF-α. (R)-KT109 is widely used in studies of metabolic syndrome-related diseases and neuroinflammation.
