1-Piperonylpiperazine
1-Piperonylpiperazine (MDBP) is metabolized by demethylenation and subsequent methylation to N-(4-hydroxy-3-methoxybenzyl)piperazine followedby partial glucuronidation or sulfation. 1-Piperonylpiperazine can alter the disposition and metabolism of 3,4-methylenedioxymethamphetamine (MDMA) in the brain and in peripheral organs. 1-Piperonylpiperazine can inhibit the MDMA-induced neurotoxicity.
