Most of the 5-MeO group are part of the tryptamine group of drugs. Tryptamines drugs are generally hallucinogenic and increase the release of the neurotransmitter serotonin (involved in regulating mood, appetite, sleep, memory and learning) while inhibiting its reuptake (recycling).
Very little pharmacological information is available for 5-MeO DALT. It has been suggested by it binds with a specific serotonin receptor (the 5-HT1 receptor) while blocking the serotonin transporter (SERT) which absorbs serotonin molecules after they have transmitted signals so they can be used again.
5-MeO-AMT is a synthetic, long-acting tryptamine that operates in much the same way as the other tryptamines. It is active at very low doses, many times smaller than most of the other 5-MeOs.
N,N-diisopropyl-5-methoxy-tryptamine (5-MeO-DiPT) and N-isopropyl-5-methoxy-N-methyl-tryptamine (5-MeO-MiPT) are synthetic chemical tryptamines and thus are structurally related to other tryptamines (natural and synthetic), such as 5-MeO-DMT, N,N-DMT, psilocybin and serotonin.
