Substituted amphetamines

Generic structure of an amphetamine molecule

Substituted amphetamines are a family of modified amphetamine molecules that include compounds with psychoactive effects, which typically have classical stimulant but may also include entactogenic (e.g. MDA and MDMA) and psychedelic effects (e.g. DOx or TMA-6).

Chemistry

Substituted amphetamines are a class of chemicals that have structures based on the molecular backbone of amphetamine with different substitutions at varying positions. Of note, an amphetamine molecule has the structure of a phenethylamine molecule with an additional methyl group located on the alpha carbon. Thus, in addition to being the only unsubstituted member of the substituted amphetamine class, amphetamine can also considered ton be a substituted phenethylamine.

Pharmacology

The substituted amphetamine class of psychedelic, entactogenic and stimulant drugs works via their action upon numerous receptors. Psychedelic effects can be attributed to action on the 5-HT_2A receptor. Entactogenic and stimulant effects are due to their action as releasing agents of serotonin, adrenaline and noradrenaline or as agonists on the receptors of the previous neurotransmitters. The agonism of this set of receptors leads to an increased rate firing of the post-synaptic neuron, triggering both cognitive and physical stimulation within the user.
