The solid-state structures of N-ethyl-4-hy-droxy-tryptamine (4-HO-NET) {systematic name: 3-[2-(ethyl-amino)-eth-yl]-1H-indol-4-ol}, C12H16N2O, and 4-hy-droxy-N-propyl-tryptamine (4-HO-NPT) {systematic name: 3-[2-(propyl-amino)-eth-yl]-1H-indol-4-ol}, C13H18N2O, are reported. Both compounds possess a single tryptamine mol-ecule in the asymmetric unit that exhibits an inter-nal O-H⋯N hydrogen...
High Resolution Image Download MS PowerPoint Slide Tryptamine psychedelics induce psychoactive effects via agonist actions at serotonin 2A receptors (5-HT 2A ), but the compounds are generally nonselective. 4-Methoxy- N -methyl- N -isopropyltryptamine (4-MeO-MiPT) is a 5-HT 2A agonist which also blocks the 5-HT transporter (SERT) and has blunted visual and other psychedelic effects in humans....
5-methoxy-N,N-dimethyltrytpamine (5-MeO-DMT) analogs are used as recreational drugs, but they are also being developed as potential medicines, warranting further investigation into their pharmacology. Here, we investigated the neuropharmacology of 5-MeO-DMT and several of its N-alkyl, N-allyl, and 2-methyl analogs, with three major aims: 1) to determine in vitro receptor profiles for the...
Analogues of 4-phosphoryloxy-N,N-dimethyltryptamine (psilocybin) are being sold on recreational drug markets and developed as potential medications for psychedelic-assisted therapies. Many of these tryptamine-based psilocybin analogues produce psychedelic-like effects in rodents and humans primarily by agonist activity at serotonin 2A receptors (5-HT2A). However, the comprehensive...
The title compound, 4-hydroxy- N -isopropyltryptamine ( 4 ) or 4-HO-NiPT (systematic name: 3-{2-[(propan-2-yl)amino]ethyl}-1 H -indol-4-ol), C 13 H 18 N 2 O, was synthesized in three steps from 4-benzyloxyindole ( 1 ) (systematic name: 4-phenoxy-1 H -indole), C 15 H 13 NO. ( 1 ) was treated with oxalyl chloride and isopropylamine to produce N -isopropyl-4-benzyloxy-3-indoleglyoxylamide ( 2 )...
4-Phosphoryloxy-N,N-dimethyltryptamine (psilocybin) is a naturally occurring tertiary amine found in many mushroom species. Psilocybin is a prodrug for 4-hydroxy-N,N-dimethyltryptamine (psilocin), which induces psychedelic effects via agonist activity at the serotonin (5-HT) 2A receptor (5-HT2A). Several other 4-position ring-substituted tryptamines are present in psilocybin-containing...
The title compound, baeocystin or 4-phosphoryloxy- N -methyltryptamine {systematic name: 3-[2-(methylazaniumyl)ethyl]-1 H -indol-4-yl hydrogen phosphate}, C 11 H 15 N 2 O 4 P, has a single zwitterionic molecule in the asymmetric unit. The molecule has an intramolecular N—H...O hydrogen bond between the ammonium cation and the hydrophosphate anion. In the crystal, the molecules are linked by...
