Generic structure of a phenethylamine molecule

Phenethylamine (also called PEA, β-phenylethylamine, β-phenethylamine, or benzeneethanamine) is a trace amine and influencer of many neurotransmitters, such as dopamine and serotonin. Phenethylamine is an important molecule in the brain, but is not often used as a supplement because it is rapidly broken down into inactive components before it is able to reach and cross the blood-brain barrier.[1]

Phenylethylamine functions as a monoaminergic neuromodulator and, to a lesser extent, a neurotransmitter in the human central nervous system. In addition to its presence in mammals, phenethylamine is found in many other organisms and foods, such as chocolate.[2] It is also plays a role in feelings of affection, and this mechanism is perhaps partially responsible for its ability to enhance empathy, affection, and sociability.[3]

When taken in combination with an MAOI such as hordenine, it can produce profound entactogenic effects similar to that of MDMA. However, the effects are notably shorter-lived and accompanied by more severe side effects. A thorough investigation of 179 phenethylamine compounds was published by Ann and Alexander Shulgin under the title PiHKAL.

Chemistry

Phenethylamine is comprised of a benzene ring attached to a mono-amine group via an ethyl side-chain. Orally ingested without a MAOI, phenethylamine goes through extensive first-pass metabolism by monoamine oxidase B (MAO-B) and then aldehyde dehydrogenase (ALDH), which metabolize it into phenylacetic acid. This prevents significant concentrations from reaching the brain in low doses.[4]

In the body, it is biosynthesized from the amino acid L-phenylalanine by enzymatic decarboxylation via the enzyme aromatic L-amino acid decarboxylase.[5]

Hydrogen atoms around the structure can be substituted for other functional groups to produce drugs of varying potency, affinity, efficacy, and half-life.

Pharmacology

Several neurotransmitters are derived from phenethylamine such as adrenaline, dopamine, norepinephrine.

Subjective effects

This subjective effects section is a stub.

As such, it is still in progress and may contain incomplete or wrong information.

Disclaimer: The effects listed below are taken from the subjective effect index, which is based on anecdotal reports and the personal experiences of PsychonautWiki contributors. As a result, they should be treated with a healthy degree of skepticism. It is worth noting that these effects will rarely (if ever) occur all at once, although higher doses will increase the chances of inducing a full range of effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.

The effects described are most often associated with combining phenethylamine with a MAOI such as hordenine, but may be present by itself in high doses.
