A direct comparison was made of the effects of serotonin 5-HT1A and 5-HT1B selective compounds on the spontaneous firing rate of dorsal raphe serotoninergic neurons in chloral-hydrate-anesthetized rats. Following intravenous administration, the 5-HT1A selective compounds ipsapirone (TVX Q 7821) and

This investigation evaluated the effects of the 1-arylpiperazines (1-(1-naphthyl)piperazine (1-NP), 1-(2-[4-aminophenylethyl]-4-[3-trifluoromethylphenyl]piperazine (PAPP), 1-(3-trifluoromethylphenyl)piperazine (TFMPP) and 1-(3-chlorophenyl)piperazine (mCPP) on head-twitching elicited by central 5-hydroxytryptamine2, (5-HT2) agonists and on the 5-HT motor syndrome associated with stimulating 5-HT1A receptors in rodents. 1-NP (0.25-16.0

1-[(4-Aminophenyl)ethyl]-4-[3-(trifluoromethyl)phenyl]piperazine (PAPP) is a 5-HT(1A) agonist and was reported to display high affinity for serotonin (5-HT) receptor from the parasitic nematode Haemonchus contortus . The present investigation explored the possibility of using PAPP as a lead compound of new insecticides

1-[2-(4-Aminophenyl)ethyl]-4-(3-trifluoromethylphenyl)piperazine (PAPP) inhibits [3H]5-hydroxytryptamine (5-HT, serotonin) binding to 5-HT1A and 5-HT1B sites in rat brain with apparent equilibrium dissociation constants (KD) of 2.9 and 328 nM, respectively. [3H]PAPP was synthesized, its binding to central serotonin receptors was examined, and its

1-[2-(4-aminophenyl)ethyl]-4-(3-trifluoromethylphenyl)piperazine (LY 165163, PAPP) (1 mg/kg s.c.) significantly decreased 5-hydroxytryptophan (5-HTP) accumulation in cortex, hippocampus, striatum, septum, pons + medulla and midbrain and increased DOPA accumulation in the cortex and striatum following inhibition of aromatic amino acid decarboxylase with NSD
