Arylalkylamine
Substituted arylalkylamines are a group of chemical compounds. Two major classes of arylalkylamines include indolylalkylamines (e.g., tryptamines (a.k.a. indolylethylamines)) and phenylalkylamines (e.g., phenethylamines and amphetamines (a.k.a. phenylisopropylamines)), which consist of the monoamine neurotransmitters as well as clinically-used and recreationally-abused monoaminergic drugs, including psychostimulants, anorectics, wakefulness-promoting agents, bronchodilators, decongestants, antidepressants, entactogens, and psychedelics, among others.
