FHATHBIN, also known as 5-hydroxy-11-aminotetrahydrobenzindole or as 4,α-methylene-5-HT, is a serotonin receptor agonist of the partial ergoline group. It is a cyclized tryptamine and tricyclic derivative of serotonin (5-hydroxytryptamine) as well as a simplified analogue of LSD. The drug is known to act on the serotonin 5-HT1A receptor. FHATHBIN was first reported in the scientific literature by 1984.

Partial lysergamide

Partial or simplified ergolines and lysergamides, also known as deconstructed LSD analogues, are analogues of ergolines and lysergamides like the psychedelic drug LSD in which one or more atoms or bonds, for instance within the ergoline ring system, have been removed. Additional substitutions may also be added, for instance on the A ring of the ergoline nucleus.

RU-27849

RU-27849, also known as 4,α-methylenetryptamine, is a serotonin receptor modulator. It can be regarded as a conformationally restricted tricyclic derivative of tryptamine or a structurally simplified derivative of LSD. This molecule was developed during structure-activity relationship (SAR) studies of LSD. It shows affinity for serotonin receptors, including for the serotonin 5-HT1, 5-HT1A, and 5-HT2 receptors (IC50Tooltip half-maximal inhibitory concentration = 267-520 nM, 325-326 nM, and 1,964-2,900 nM, respectively).

Bay R 1531

Bay R 1531, also known as LY-197206 or as 4,α-methylene-5-MeO-DPT, is a tricyclic tryptamine derivative. It acts as a selective serotonin 5-HT1A receptor agonist.
