Difluoromethylenedioxyamphetamine (DiFMDA) is a substituted derivative of methylenedioxyamphetamine (MDA), which was developed by Daniel Trachsel and coworkers, along with the corresponding fluorinated derivatives of MDMA, MDEA, BDB and MBDB, with the aim of finding a non-neurotoxic drug able to be used as a less harmful substitute for entactogenic drugs such as MDMA. Since a major route of the normal metabolism of these compounds is scission of the methylenedioxy ring, producing neurotoxic metabolites such as alpha-methyldopamine, it was hoped that the difluoromethylenedioxy bioisostere would show increased metabolic stability and less toxicity. These compounds have not yet been tested in animals to verify whether they show similar pharmacological activity to the non-fluorinated parent compounds, although ''in vitro'' binding studies show DFMDA to have a SERT affinity in between that of MDA and MDMA. However there is known to be a lack of bulk tolerance at this position of the molecule, shown by the generally reduced activity of the ethylidenedioxy and isopropylidenedioxy analogues. It is also now generally accepted that MDMA neurotoxicity results from a variety of different causes and is not solely due to accumulation of alpha-methyldopamine, making it unclear how much less neurotoxic DFMDA and related drugs would be in practice. ==See also== * 6-APB * EIDA * IAP * MDAI 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DiFMDA」の詳細全文を読む スポンサード リンク
