(s) kt109

(S)-KT109 is the (S) isomer of the diacylglycerol lipase β (DAGLβ) inhibitor KT109 . (S)-KT109 is a less potent inhibitor of DAGLβ (IC50 = 39.81 nM), DAGLα-mediated hydrolysis of 1-stearoyl-2-arachidonoyl-sn-glycerol (IC50 = 794.3 nM), and α/β-hydrolase domain-containing protein 6 (ABHD6; IC50 = 630.9 nM) than (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 .
