Detailed description of Alpha-Ethyltryptamine

By

Alpha-Ethyltryptamine is a effective drug and which is monoamine oxidase inhibitor and potent monoamine releasing agent, has been sold illicitly as a substitute for the entactogen 3,4-methylenedioxy-N-methylamphetamine (MDMA), and is the first example of an indolealkylamine analog demonstrated to substitute in MDMA-trained animals.

The last studies have demonstrated that MDMA and AET have similar effects on unconditioned motor behavior in rats. Furthermore, the locomotor-activating effects of both MDMA and AET are blocked by pretreatment with fluoxetine, a selective serotonin (5-HT) uptake inhibitor, suggesting that the two compounds may share a presynaptic mechanism of action. This study examined the effects of AET using measures of startle plasticity, specifically prepulse inhibition (PPI), and habituation. PPI, a measure of sensorimotor gating, is reduced in rats treated with hallucinogens, 5-HT releasers, and dopamine agonists.

In contrast, startle habituation is reduced in rats treated with hallucinogens and 5-HT releasers. AET (1.25, 2.5, 5, and 10 mg/kg) decreased PPI of acoustic startle and reduced the habituation of tactile startle. To determine whether AET produces these effects via pre- or postsynaptic actions, fluoxetine (10 mg/kg) was used as a pretreatment. By itself, fluoxetine did not disrupt PPI, but did reduce startle habituation. Fluoxetine pretreatment prevented the AET-induced disruption of PPI and reduced the AET-induced disruption of startle habituation. According the previous findings, these results confirm that Alpha-Ehtyltryptamine creates behavioral effects that mimic those of other indirect 5-HT agonists and that the effects of AET on startle plasticity are due to the release of presynaptic 5-HT.
