TFMFly is a compound related to psychedelic phenethylamines such as 2C-B-FLY and 2C-TFM. It was first reported in 2005 by a team at Purdue University led by David Nichols.[1] It acts as a potent agonist at the 5HT2A serotonin receptor subtype, and is a chiral compound with the more active (R) enantiomer having a Ki of 0.12 nM at the human 5HT2A receptor.[2] While the fully aromatic benzodifurans such as Bromo-DragonFLY generally have higher binding affinity than saturated compounds like 2C-B-FLY,[3] the saturated compounds have higher efficacy as agonists.[4]

Legal Status[edit]

TFMFly is illegal in Latvia.[5]
