To support ongoing clinical trials, the major human metabolites of psilocybin were synthesized on a preparative scale, specifically psilocin-O-glucuronide and 4-hydroxyindole-3-acetic acid (4-HIAA), along with putative minor metabolites and several deuterium-labeled derivatives. Psilocybin, psilocin, psilocin-O-glucuronide, and 4-HIAA were assayed for engagement at seven serotonin receptor...
Antibodies against small psychoactive molecules have been developed for applications ranging from substance detection and overdose protection to mechanistic understanding of the actions of complex substance mixtures. In this study, we describe the design, synthesis, formulation, and animal testing of an initial immunogenic bioconjugate, as well as subsequent isolation of enantiospecific...
