in vitro study | JNJ-63533054 specifically activates human GPR139 in the calcium mobilization (EC 50 of 16 nM) and GTP γ S binding (EC 50 of 17 nM) assays. JNJ-63533054 also activates the rat and mouse GPR139 receptor with similar potency (rat EC 50 of 63 nM, mouse EC 50 of 28 nM). In a saturation study for human GPR139, A single population of high-affinity binding sites for [3H] JNJ-63533054 is observed (K d of 10 nM). The B max value is 26 pmol/mg of protein. Saturation studies for the rat GPR139 and mouse GPR139 yielded K d values in the same range (32 nM and 23 nM, respectively; B max = 8.5 pmol/mg of protein and 6.2 pmol/mg of protein, respectively). |
in vivo studies | JNJ-63533054 (3-30 mg/kg; oral administration; once; SD rats) treatment induces a dose-dependent reduction in locomotor activity in the first hour. The pharmacokinetics of JNJ-63533054 (Compound 7c; 1 mg/kg iv; 5 mg/kg po) in rat is examined. The IV clearance is 53 mL/min/kg, the C max is 317 ng/ml (~ 1 μ m), the t 1/2 is 2.5 hours, and JNJ-63533054 is able to cross the blood-brain barrier (BBB) with a brain to plasma ratio (B/p) of 1.2. Animal model: male Sprague-Dawley rat (350-450g) Dosage: 3 mg/kg, 10 mg/kg, and 30 mg/kg Administration: Oral administration; Once Result: Induced a dose-dependent reduction in locomotor activity in the first hour. |
