5-Fluoro-N,N-dimethyltryptamine (5-fluoro-DMT, 5F-DMT) is a tryptamine derivative related to compounds such as 5-bromo-DMT and 5-MeO-DMT.[1] Fluorination of psychedelic tryptamines either reduces or has little effect on 5-HT2A/C receptor affinity or intrinsic activity, although 6-fluoro-DET is inactive as a psychedelic despite acting as a 5-HT2A agonist (cf. lisuride), while 4-fluoro-5-methoxy-DMT is a much stronger agonist at 5-HT1A than 5-HT2A.[2][3]
