ACT-462206 is an orally active and potent dualOrexin 1/Orexin 2receptor antagonist withIC₅₀s of 60 nM (Orexin 1) and 11 nM (Orexin 2), respectively. ACT-462206 exhibits brain penetration properties, and can be used for insomnia, stress/anxiety-related disorders and addiction research^[1].

Orexins are released in a Ca²⁺-sensitive manner at axonal terminals and can then bind to two closely related G-protein-coupled receptors (GPCRs): orexin receptor type 1 (OX1) and orexin receptor type 2 (OX2)^[1].
ACT-462206 shows binding affinity with K_bs of 17 nM (hOX1), 2.4 nM (hOX2), 28 nM (rOX1), 9.9 nM (rOX2), 27 nM (dOX1), 4.2 nM (dOX2), respectively^[1].
ACT-462206 inhibits Orexin activity with IC₅₀s of 60 nM (hOX1), 11 nM (hOX2), 48 nM (rOX1), 9.6 nM (rOX2), 68 nM (dOX1), 26 nM (dOX2), respectively^[1].
ACT-462206 inhibits CYP450 3A4T and 3A4M with IC₅₀s of 15 μM and 29 μM, respectively^[1].

ACT-462206 (compound 24) (100 mg/kg; p.o.; sampling at 3 h) can go cross blood brain barrier, with concentrations are 2267 ng/mL and 1219 ng/g in plasma and brain, respectively in male Wistar rats^[1].
ACT-462206 (10-300 mg/kg; p.o.; single dose) shows sleep-promoting effects in male Wistar rats and in male Beagle dogs, with decreasing wakefulness and increasing non-rapid eye movement (non-REM) and REM sleep^[1].
ACT-462206 (100, 300 mg/kg; p.o.; single dose) exerts anxiolytic-like effects, decreases the fear-potentiated startle reflexes in response to a sudden loud noise in rats, reduces the socialstress-induced increases of locomotion, body temperature, and heart rate^[1].
