Shulgin Seminar Session 4: Structure-Activity Relationship

The chemical structure of various psychotomimetic substances is analyzed in the context of their structure activity relationship (SAR). The discussion centers on the development of these substances as observed through Alexander Shulgin's research papers, dating from the late 1960s to the 1990s. The progression of research from initial clinical observations to more deliberate synthetic modifications is examined in detail, with a focus on specific chemical changes like side chain lengthening and the addition of methoxy groups. Structural insights are presented on how such modifications affect substance potency and subjective experience, highlighting the methodological shift toward more systematic mapping of psychoactive effects against chemical structures.
