Use | A selective and reversible inhibitor of fatty acid amide hydrolase (FAAH). |
In vitro study | Preincubation of FAAH with JNJ-1661010 showed that JNJ-1661010 and active site interactions were slowly reversible and accelerated at high temperatures. LC-ESI-MS assays indicate that JNJ-1661010 is a covalent, mechanism-based substrate inhibitor. JNJ-1661010 docked with phenythiadiazole in the hydrophobic channel and with phenylurea in the hydrophilic pocket of FAAH. |
In vivo study | JNJ-1661010(20 mg/kg I. p.) inhibited FAAH by at least 85% and the effect was maintained for more than 4 h after administration, resulting in accumulation of lipid ethanolamide in the rat brain. In mild heat-injured (MTI) mouse and rat models, JNJ-1661010 dose-dependently reverses tactile allodynia, with maximal efficacy of approximately 90% at 30 minutes after administration. In a rat spinal nerve ligation injury model, JNJ-1661010 (20 mg/kg) reversed 60.8% tactile allodynia at 30 min. In the rat carrageenan inflammatory pain model, JNJ-1661010 (50 mg/kg I. p.) significantly attenuated hyperalgesia 30 minutes after administration. Rats were treated with JNJ-1661010 (20 mg/kg I. p.) administration, a plasma Cmax of 26.9 μm at Tmax of 0.75 h and a Cmax of 6.04 μm in the brain at Tmax of 2 h. JNJ-1661010 (20 mg/kg I. p.) inhibited FAAH in rat brain and increased AEA levels in brain tissue. |
