In Vivo (Rac)-WAY-161503 (3-30 mg/kg; intraperitoneal injection; male C57BL/6J mice) treatment dose-dependently decreases locomotor activity, an effect that is blocked by the 5-HT2C/2B antagonist SER-082. Additionally, the decreased locomotor activity produced by 10 mg/kg DOI is potentiated in the 5-HT2A KO mice[1]. Animal Model: Male C57BL/6J mice with hallucinogen 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI)[1] Dosage: 3 mg/kg, 10 mg/kg, 30 mg/kg Administration: Intraperitoneal injection Result: Dose-dependently decreased locomotor activity, an effect that was blocked by the 5-HT2C/2B antagonist SER-082.
