(R) -KT109

(R) -KT109 is the (R) isomer of the diacylglycerol lipase β (DAGLβ) inhibitor KT109 . (R) -KT109 is an inhibitor of DAGLβ (IC50 = 0.79 nM) and of DAGLα-mediated hydrolysis of 1-stearoyl-2-arachidonoyl-sn-glycerol . It also inhibits α/β-hydrolase domain-containing protein 6 (ABHD6) with an IC50 value of 2.51 nM. (R) -KT109 is more potent at DAGLβ, DAGLα, and ABHD6 than (S) -KT109 .
