Alpha-ethyltryptamines as dual dopamine-serotonin releasers
The dopamine (DA), serotonin (5-HT), and norepinephrine (NE) transporter releasing activity and serotonin-2A (5-HT2A) receptor agonist activity of a series of substituted tryptamines are reported. Three compounds, 7b, (+)-7d and 7f, were found to be potent dual DA/5-HT releasers and were >10-fold less potent as NE releasers. Additionally, these compounds had different activity profiles at the 5-HT2Areceptor. The unique combination of dual DA/5-HT releasing activity and 5-HT2Areceptor activity suggests that these compounds could represent a new class of neurotransmitter releasers with therapeutic potential.

A versatile linkage strategy for solid-phase synthesis of N,N-dimethyltryptamines and β-carbolines
(matrix presented) Various tryptamines are captured by a vinylsulfonylmethyl polystyrene resin, generating a safety-catch linkage. β-Carbolines can be formed from 4 by a Pictet-Spengler reaction with the introduction of R1. Tryptamine 4 can also be derivatized by acylation or copper-mediated coupling to introduce R2. If X = Br, Suzuki coupling can be used to introduce R3. After derivatization, the indole derivatives are activated with methyl iodide and released under mild basic condition.

Electron Impact and Chemical Ionization Fragmentation of 5-Methoxytryptamine and Some 6-Methoxy-β-carbolines
Electron impact (EI) and chemical ionization (CI) mass spectra of 5-methoxytryptamine (5-MT) and seven 6-methoxy-β-carbolines have been recorded and interpreted.Proposed fragmentation pathways are depicted on the basis of spectra of deuterium labelled analogs of 5-MT, 6-methoxy-1,2,3,4-tetrahydro-β-carboline (6-MeO-THBC) and 6-Methoxy-1-methyl-1,2,3,4-tetrahydro-β-carboline (6-MeO-1-Me-THBC).In the EI mass spectrum of 5-MT, the base peak m/z 160 is formed by the expulsion of CH4N.The positive ion so formed is suggested to have a quinolinium structure.In chemical ionization with CH4 as the reaction gas, the most abundant ion is produced by cleavage of NH3.The ion m/z 173 yields the base peak in the EI mass spectrum of 6-MeO-THBC.This ion is formed by a retro Diels-Alder reaction, an important fragmentation pathway of 6-MeO-1-Me-THBC, too. 6-MeO-harmalan easily loses one hydrogen atom in EI fragmentation followed by methyl loss from the methoxy group, this latter process yielding the base peak, m/z 197 in the EI mass spectrum of 6-MeO-harman.M+1 is the base peak in the CI mass spectra of all 6-MeO-β-carbolines.

Mass spectra of some specifically deuterated tryptamines.
The mass spectra of the four tryptamine derivatives, N-acetyl-5-methoxytryptamine (melatonin), N-acetyl-5-hydroxytryptamine (N-acetyl-serotonin), N,N-dimethyl-5-hydroxtryptamine (bufotenine) and N,N-dimethyl-5-methoxytryptamine (O-methylbufotenine), with specifically labeled [D4] aminoethyl sidechains have been measured. Comparison of these spectra with those of the unlabeled compounds enable the major fragmentations of the compounds to be defined.
