(6aS-Trans)-11-chloro-6,6a,7,8,9,13b-hexahydro-7-methyl-5H-benzo[d]naphth[2,1-b]azepin-12-ol hydrobromide

Description

SCH 39166 is a dopamine D₁ receptor antagonist (K_i = 5 nM). It is selective for D₁ over D_2-4 receptors (K_is = 3,751, >1,000, and 5,934 nM, respectively), however, it also binds to D₅ receptors (K_i = 4.4 nM). SCH 39166 inhibits food intake in a dose-dependent manner in rats (ED₅₀ = 0.84 mg/kg). It reduces ethanol intake in Sardinian alcohol-preferring rats and sucrose intake in water-deprived and water-sated rats without affecting food or total fluid intake. SCH 39166 also suppresses cocaine-induced arrhythmias in anesthetized dogs.

Uses

SCH 39166 is a dopamine D1/D5 receptor antagonist used in the treatment of schizophrenia, cocaine addiction and obesity.
