JNJ-26489112 (i.p.) effectively blocks chemically-induced, forelimb clonic seizures in mice ( male CF-1 albino mice) that are caused by subcutaneous bicuculine (Bic), picrotoxin (Pic), or pentylenetetrazol (PTZ), with 1-h ED50 values of 197, 189, or 109 mg/kg, respectively[1].
In adult male rats, JNJ-26489112 (p.o; 10 mg/kg) treatment shows the Cmax, tmax, F, t1/2, and AUC (total exposure) values in plasma were 9090 ng/mL (33 μM), 53 min, 95%, 8.2 h, and 53,200 ng-h/mL. Linear, dose-related increases in exposure were observed at 10, 30, and 300 mg/kg. JNJ-26489112 (i.v.; 2 mg/kg) treatment shows the Vdss is 390 mL/kg and the CL is 96 mL/h-kg. In female beagle dogs, JNJ-26489112 (p.o; 10 mg/kg) treatment shows the Cmax, tmax, F, t1/2, and AUC values in plasma are 11,500 ng/mL (41 μM), 55 min, 83%, 20 h, and 212,000 ng-h/mL. . JNJ-26489112 (i.v.; 2 mg/kg) treatment shows the the Vdss and CL values are 630 mL/kg and 30 mL/h-kg, respectively[1].
