(R) -KT109

(R) -KT109 is a highly potent inhibitor of diacylglycerol lipase β (DAGLβ) with an IC50 of 0.79 nM and effectively blocks DAGLα-mediated hydrolysis of 1-stearoyl-2-arachidonoyl-sn-glycerol. Additionally, it demonstrates inhibitory activity against α/β-hydrolase domain-containing protein 6 (ABHD6) with an IC50 of 2.51 nM, exhibiting greater potency for DAGLβ, DAGLα, and ABHD6 compared to its (S) isomer, (S) -KT109.
