Enhancement of the vagally induced bradycardia elicited by low doses of 5-CT was reproduced by the selective 5-HT (1A) receptor agonist 8-hydroxydipropylaminotretalin hydrobromide (8-OH-DPAT; 50 microg/kg).

N-arachidonoylserotonin (AA-5-HT, 1a) is an inhibitor of fatty acid amide hydrolase (FAAH) that acts also as an antagonist of transient receptor potential vanilloid-type 1 (TRPV1) channels and is analgesic in rodents.

In an effort to elucidate aripiprazole's pharmacological activity in relation to clinically relevant fluctuation of dopamine D (2) receptor reserves, we compared the properties of aripiprazole to other antipsychotics, quetiapine, clozapine, olanzapine, ziprasidone, risperidone and haloperidol, a dopamine D (2) receptor partial agonist, bifeprunox, dopamine D (3) receptor modulators, BP897 (N-[4-[4-(2-Methoxyphenyl)-1-piperazinyl] butyl] naphthalene-2-carboxamide) and GR103691 (4'-Acetyl-N-[4-[4-(2-methoxyphenyl) piperazin-1-yl] butyl] biphenyl-4-carbox amide), and a 5-HT (1A) partial agonist, buspirone using forskolin-stimulated cAMP accumulation in clonal Chinese hamster ovary cell lines expressing low and high densities of human dopamine D (2S) receptors (hD (2S)-Low and hD (2S)-High, respectively).

While acute administration of the tachykinin NK1 receptor antagonist CP-96,345 (10 mg/kg, i.p.) attenuated the responsiveness of dorsal raphe 5-HT (1A) autoreceptors, lesioning noradrenaline neurons with the neurotoxin N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP-4) prevented the enhancing action of a 2-day treatment with CP-96,345 on 5-HT neuronal firing, suggesting that tachykinin NK1 receptor antagonists influence 5-HT system via noradrenaline neurons independently of their firing rate.
