4-HO-MPMI (also known as 4-Hydroxy-N-methyl-(α,N-trimethylene)-tryptamine or lucigenol) is a tryptaminederivative that is a psychedelic drug. It was developed by the team led by David Nichols from Purdue University in the late 1990s. This compound produces hallucinogen-appropriate responding in animal tests with a similar potency to the amphetamine-derived psychedelic DOI, and has two enantiomers, with only the (R)-enantiomer being active.[1]
The binding affinity for 5-HT2A receptor is 13 ± 2 nM (Ki [125I]DOI). It is reported at doses starting at 0.5 mg and 1.0-1.5 mg seem to be psychedelic doses. The duration it is reported between six and eight hours. The effects, still not too documented, are OEV/CEV, sedation and anxiety.[2][unreliable source?]
