In the present study, we synthesized a new hybrid compound by coupling caffeic acid and 1-piperonylpiperazine. The synthetic compound, acetyl-caffeic acid-1-piperonylpiperazine (HBU-47), showed potent anti-inflammatory effects inhibiting lipopolysaccharide (LPS)-induced production of nitric oxide (NO) in RAW264.7 macrophage cells. HBU-47 inhibited

The effects of 1-piperonylpiperazine and N,alpha-dimethylpiperonylamine, which are weak inhibitors for [3H]5-hydroxytryptamine (5-HT) uptake, on 3,4-methylenedioxymethamphetamine (MDMA)-induced neurotoxicity were examined. The reductions of serotonergic parameters in the rat cerebral cortex produced by multiple administration of MDMA (10 mg/kg) were attenuated

Metabolism studies play an important role in clinical and forensic toxicology. Because of potential species differences in metabolism, human samples are best suitable for elucidating metabolism. However, in the case of new psychoactive substances (NPS), human samples of controlled studies
The neurotoxicity of 3,4-methylenedioxymethamphetamine (MDMA) in rat brain was attenuated significantly by coadministration of several benzylpiperazines (p-nitrobenzylpiperazine, p-chlorobenzylpiperazine and 1-piperonylpiperazine), which were weak inhibitors for [3H]6-nitroquipazine binding to the 5-hydroxytryptamine (5-HT) transporter in rat brain. These results suggest that these

The piperazine derivatives most frequently consumed for recreational purposes are 1-benzylpiperazine, 1-(3,4-methylenedioxybenzyl) piperazine, 1-(3-trifluoromethylphenyl) piperazine and 1-(4-methoxyphenyl) piperazine. Generally, they are consumed as capsules, tablets or pills but also in powder or liquid forms. Currently, the precise mechanism by which
