6-Fluoro-DET (6F-DET, 6-fluoro-N,N-diethyltryptamine) is a substituted tryptamine derivative related to drugs such as DET and 5-fluoro-DET. It acts as a partial agonist at the 5-HT2A receptor, [1] but while it produces similar physiological effects to psychedelic drugs, it does not appear to produce psychedelic effects itself even at high doses. Relatedly, 6-F-DET does not substituted for LSD in drug discrimination tests and does not produce the head-twitch response in rodents. [1] [2] [3] For the preceding reasons, it saw some use as an active placebo in early clinical trials of psychedelic drugs but was regarded as having little use otherwise, [4] though more recent research into compounds such as AL-34662, TBG and zalsupindole has shown that these kind of non-psychedelic 5-HT2A agonists can have various useful applications. [5] [6] [7] [8] [9] [10]

A hypothesis for the lack of head-twitch response in mice and hallucinogenic effects in humans is that 6-F-DET acts as a 5-HT2A receptor partial agonist of the Gq signaling pathway. [1] This hypothesis explains the lack of hallucinogenic effects of other 5-HT2A receptor ligands, which are also weak Gq agonists and below the efficacy threshold found to induce psychedelic effects, like 25N-N1-Nap, 2-Br-LSD, lisuride, tabernanthalog, and 6-MeO-DMT.
