5-MeO-MPMI (also known as 5-Methoxy-N-methyl-(α,N-trimethylene)tryptamine) is a tryptamine derivative that is a psychedelic drug. It was first developed by the team led by JE Macor in 1992,[1] and subsequently investigated by the team led by David Nichols from Purdue University in the late 1990s. This compound produces psychedelic-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.[2]
