In-vitro and in-vivo characterization of JNJ-7925476, a novel triple monoamine uptake inhibitor.
Triple reuptake inhibitors, which block the serotonin transporter (SERT), norepinephrine transporter (NET) and dopamine transporter (DAT) in the central nervous system have been described as therapeutic alternatives for classical selective serotonin reuptake inhibitors, with advantages due to their multiple mechanisms of action. JNJ-7925476 (trans-6-(4-ethynylphenyl)-1,2,3,5,6,10b-hexahydropyrrolo[2,1-a]isoquinoline) is a selective and potent inhibitor of the SERT, NET, and DAT (K(i)=0.9, 17 and 5.2 nM, respectively). Following subcutaneous dosing in rat, JNJ-7925476 was rapidly absorbed into the plasma, and drug concentrations in the brain tracked with those in the plasma but were 7-fold higher. The ED(50) values for JNJ-7925476 occupancy of the SERT, NET, and DAT in rat brain were 0.18, 0.09 and 2.4 mg/kg, respectively. JNJ-7925476 (0.1-10 mg/kg, s.c.) rapidly induced a robust, dose-dependent increase in extracellular serotonin, dopamine, and norepinephrine levels in rat cerebral cortex. The compound also showed potent antidepressant-like activity in the mouse tail suspension test (ED(50)=0.3 mg/kg, i.p.). These results demonstrate that JNJ-7925476 is a triple reuptake inhibitor with in-vivo efficacy in biochemical and behavioral models of depression.
