Animal experiment: | Two hundred and fifty-seven male mice are used in this study. Animals are divided into 19 groups (n=8). The first group receives physiological saline, the second receives 40 mg/kg of morphine and the other eight groups receive 0.5, 1, 2, 4, 8, 16, 24 or 32 mg/kg of Pentiapine, respectively. The remaining groups receive an injection of morphine and 30 min afterwards, an injection of physiological saline, 0.5, 1, 2, 4, 8, 16, 24 or 32 mg/kg of Pentiapine, respectively. In the groups receiving only one injection, animals are placed onto the sensory plates for a period of 90 min immediately after treatment. The computer registers the activity each 15 min. In the groups receiving two injections, animals are placed onto the sensory plates immediately after the first injection for a period of 30 min then after the second injection the motor activity is registered at 15, 30, 45 and 60 min[1]. |
产品描述 | Pentiapine is a novel dopamine release inhibitor. Pentiapine is a novel dopamine release inhibitor.The results show that Pentiapine dose-dependently reduces motor activity of mice. Moreover, Pentiapine dose-dependently reduces morphine-induced hyperactivity. Newman-Keuls post-hoc comparisons indicate that the group receiving morphine plus saline presents more activity than the groups receiving morphine plus 2 (P<0.05), 4, 8, 16, 24 and 32 (P<0.01) mg/kg of Pentiapine. Moreover, the groups receiving morphine plus 0.5, 1 and 2 mg/kg of Pentiapine present more activity than the groups receiving morphine plus 4, 8, 16, 24 and 32 mg/kg of Pentiapine (P<0.01)[1]. 30 mg/kg dose of Pentiapine completely blocks the methylenedioxymethamphetamine (MDMA) conditioned place preference (CPP) and also blocks the establishment of a cocaine CPP[2].
