Ecopipam (SCH 39166) is a potent, selective and orally active antagonist of dopamine D1/D5 receptor, with Kis of 1.2 nM and 2.0 nM, respectively. Ecopipam shows more than 40-flod selectivity over D2, D4, 5-HT, and α2a receptor (Ki=0.98, 5.52, 0.08, and 0.73 μM, respectively). Ecopipam can be used for the research of schizophrenia, cocaine addition, and obesity[1][3].

| In Vitro | Ecopipam (2 μM) completely abolishes the proconvulsive effect of Dopamine (10 μM) in isolated corticohippocampal formation[2]. |
| In Vivo | Ecopipam (0.003-0.3 mg/kg; a single s.c.) abolishes Nicotine-induced enhancement of a sensory reinforcer in adult rats[3]. Ecopipam (10, mg/kg, oral administration) antagonizes Apomorphine-induced stereotypy in rats[4]. Ecopipam (5 and 10 μM, perfusion, 1 μL/min) reversibly and dose-dependently decreases acetylcholine release in the rat striatum[5]. Animal Model: Male young adult Long-Evans rats injected with Nicotine[3] Dosage: 0.003, 0.01, 0.03, 0.1, 0.3 mg/kg Administration: A single s.c. 20 min before Nicotine (0.1 mg/kg) Result: Dose-dependently reduced pressing on both active and inactive levers. |
