Notes: JNJ-42226314 is an inhibitor of monoacylglycerol lipase (MAGL; IC50 = 10 nM).{72423} It is selective for MAGL over a panel of 15 serine proteases at 10 µM. JNJ-42226314 (30 mg/kg) increases the latency to paw withdrawal in the hot plate test and the brain levels of 2-arachidonoyl glycerol (2-AG; Item No. 62160) in rats. It increases the latency to fall asleep and the development of non-rapid eye movement (NREM) and REM sleep, as well as increases the cortical levels of norepinephrine, in rats when administered at a dose of 30 mg/kg.{72424} Radiolabeled forms of JNJ-42226314 have been used for autoradiography and PET tracers for MAGL in the brains of rats and rhesus monkeys.{72425}
