What is "tfmfly"

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. It acts as a potent agonist at the 5HT serotonin receptor subtype, and is a chiral compound with the more active (R) enantiomer having a Ki of 0.12nM at the human 5HT receptor. While the fully aromatic benzodifurans such as bromodragonfly generally have higher binding affinity than saturated compounds like 2C-B-FLY, the saturated compounds have higher efficacy as agonists.
