3,4,5-Trimethoxytranylcypromine (TMT), also known as MCPA as well as trans-2-(3,4,5-trimethoxyphenyl)cyclopropylamine, is a possible psychedelic drug of the phenethylamine, scaline, and phenylcyclopropylamine families related to mescaline (3,4,5-trimethoxyphenethylamine). It is a cyclized phenethylamine and the analogue of mescaline in which the α and β positions of the ethyl side chain have been cyclized to form a cyclopropane ring. The drug may also be thought of as a structural hybrid between mescaline and the antidepressant tranylcypromine.
