5-Allyloxy-AMT, also known as 5-allyloxy-ñ-methyltryptamine, is a serotonin 5-HT<sub>2</sub> receptor agonist of the tryptamine, 5-alkyloxytryptamine, and ñ-alkyltryptamine families.
It is known to act as high-efficacy partial agonist or near-full agonist of the serotonin 5-HT<sub>2A</sub> receptor ( = 162nM; = 89%) and of the serotonin 5-HT<sub>2B</sub> receptor ( = 60nM; = 82%), whereas activity at the serotonin 5-HT<sub>2C</sub> receptor and other serotonin receptors was not reported.
5-Allyloxy-AMT was the most potent serotonin 5-HT<sub>2A</sub> receptor agonist reported in a large series of tryptamines that was evaluated in search of potent and selective serotonin 5-HT<sub>2B</sub> receptor agonists. The only exceptions were the reference serotonin 5-HT<sub>2A</sub> receptor agonists serotonin (5-HO-T) ( = 79nM; = 100%) and (S)-ñ-methylserotonin ((S)-ñMS) ( = 54nM; = 103%).
