An atypical antipsychotic
Aripiprazole is a novel and atypical antipsychotic [1].
Aripiprazole has been found to be a dopamine-serotonin system stabilizer with potent partial agonist activity at dopamine D2 and 5-HT1A receptors and antagonist activity at 5-HT2A receptors. In addition, aripiprazole has been reported to label with the agonist [125I]7-OH-PIPAT and with the antagonist [3H]spiperone with 0.34±0.02nM and 0.70±0.22nM, respectively. Besides, aripiprazole has been revealed to dose-dependently and potently inhibit the increase in cAMP accumulation stimulated by forskolin in CHO cells and HEK-293 cells. Other results have also been reported that aripiprazole completely inhibited the increase GTPase activity stimulated by the D2 receptor agonist quinpirole in rat striatal membranes [1].
