Naphthylpiperazine
Chemical compound
1-(1-Naphthyl)piperazine (1-NP ) is a drug which is a phenylpiperazine derivative . It acts as a non-selective , mixed serotonergic agent, exerting partial agonism at the 5-HT1A , 5-HT1B , 5-HT1D , 5-HT1E , and 5-HT1F receptors ,[1] [2] [3] while antagonizing the 5-HT2A , 5-HT2B , and 5-HT2C receptors .[4] [5] [6] It has also been shown to possess high affinity for the 5-HT3 , 5-HT5A , 5-HT6 , and 5-HT7 receptors ,[7] [8] [9] [10] and may bind to 5-HT4 and the SERT as well.[11] [12] In animals it produces effects including hyperphagia ,[13] [14] [15] hyperactivity ,[16] [17] and anxiolysis ,[17] [18] [19] [20] of which are all likely mediated predominantly or fully by blockade of the 5-HT2C receptor.
