5-MAPDB, also known as 5-(2-(methylamino)propyl)-2,3-dihydrobenzofuran, is an entactogen of the dihydrobenzofuran family. It is structurally related to drugs like 5-APDB and 5-MAPB, which have similar effects to MDMA and have been used as recreational drugs. 5-MAPDB has been studied to determine its pharmacological activity, and was found to be a relatively selective serotonin releaser, though with weaker actions as a releaser of other monoamines and 5-HT2 receptor family agonist, similar to older compounds such as 5-APDB.
