Novel, unifying mechanism for mescaline in the central nervous system

[[:]]

An older paper about mescaline activity, this relates to theoretical concepts of structure and function aspects of psychedelics as well, though I must admit my personal theory about structure and function is dissimilar.

A unifying mechanism for abused drugs has been proposed
previously from the standpoint of electron transfer. Mescaline
can be accommodated within the theoretical framework based
on redox cycling by the catechol metabolite with its quinone
counterpart. Electron transfer may play a role in electrical effects
involving the nervous system in the brain. This approach is in
accord with structure activity relationships involving mescaline,
abused drugs, catecholamines and etoposide.
