In Vivo	SB 221284 (0.1~1 mg/kg, i.p.) pre-treatment doses shows to block mCPP induced hypolocomotion, significantly enhances the hyperactivity induced by phencyclidine or MK-801[1]. SB 221284 (1 mg/kg, i.p.) significantly enhances the magnitude and duration of the increase induced by phencyclidine[1] Animal Model: Male Sprague Dawley rats (250–360 g)[1] Dosage: 0.1~1 mg/kg Administration: I.p. Result: Pre-treatment doses showed to block mCPP induced hypolocomotion, significantly enhanced the hyperactivity induced by phencyclidine or MK-801. Animal Model: Male Sprague Dawley rats (250–360 g)[1] Dosage: 1 mg/kg Administration: I.p. Result: Significantly enhanced the magnitude and duration of the increase induced by phencyclidine.
