JNJ-54717793, as a brain penetrant, is an orally active, selective and high affinity orexin-1 receptor (OX1R) antagonist (plasma EC50=85 ng/mL). The Ki values of JNJ-54717793 for hOX1R (human OX1R) and hOX2R are 16 nM and 700 nM, respectively. JNJ-54717793 is a potent compound of anxiety disorders[1][2].
JNJ-5471779 (30 mg/kg; p.o.; 6 hours) significantly reduces the latency for rapid eye movement (REM) sleep and prolongs the time spent in REM sleep[2].JNJ-5471779 (3~30 mg/kg; p.o.) attenuates bradycardia responses[2].JNJ-5471779 (5mg/kg; p.o.) shows low clearance[1].
