5-Metoksitriptamin (5-MT, meksamin) je derivat triptamina. On je blisko srodan neurotransmiterima serotoninu i melatoninu. Za 5-MT je pokazano da se prirodno javlja u telu u niskim nivoima.[1] On je proizvod dekarboksilacije melatonina u epifizi.[1]

5-MT deluje kao pun agonist 5-HT1, 5-HT2, 5-HT4, 5-HT6, i 5-HT7 receptora.[2][3][4][5][6][7][8] On nema afinitet za 5-HT3 receptor. Njegov afinitet za 5-HT1E receptor je veoma slab u poređenju sa drugim 5-HT1 receptorima.[5][9]
