The ongoing psychedelic renaissance has prompted a renewed search for novel drugs based on modifying existing psychedelic motifs. In this study, a synthesis of 4-bromo-N,N-dimethyltryptamine (4-Br-DMT) was achieved and used as a late-stage intermediate for analog development. Specifically, we were able to synthesize and access novel molecules by forming carbon–carbon bonds at the C4 position...
-dimethyltryptamine (DMT). Overall, the data indicate that 4-Br-DMT has a serotonergic profile without psychedelic-like effects in mice but has a reduced safety profile compared to psilocin and DMT.

Abstract Various ring-substituted α-methylphenethylamines (i.e., amphetamines) produce psychedelic-like effects that are primarily mediated by activity at 5-hydroxytryptamine 2A (5-HT 2A ) receptors. Small lipophilic substituents at the 4-position of the 2,5-dimethoxyamphetamine core structure can greatly enhance the clinical potency of such derivatives. Here, we studied the effects of various...
Serotonergic psychedelics induce the head twitch response (HTR) in mice, an index of serotonin (5-HT) 2A receptor (5-HT2A) agonism and a behavioral proxy for psychedelic effects in humans. Existing methods for detecting HTRs include time-consuming visual scoring, magnetometer-based approaches, and analysis of videos using semi-automated commercial software. Here, we present a new automated...
