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-HT2A receptor. The unique combination of dual DA/5-HT releasing activity and 5-HT2A receptor activity suggests that these compounds could represent a new class of neurotransmitter releasers with therapeutic potential
