1-Propyl-5-MeO-AMT

1-Propyl-5-MeO-AMT, also known as 1-propyl-5-methoxy-α-methyltryptamine, is a serotonin receptor modulator of the tryptamine, α-alkyltryptamine, and 5-methoxytryptamine families.^[1][2][3] It is the 1-propyl derivative of 5-methoxy-α-methyltryptamine (5-MeO-AMT).^[3]

Whereas most tryptamines are highly non-selective in terms of binding to serotonin receptors, 1-propyl-5-MeO-AMT shows selectivity for the serotonin 5-HT_2A receptor.^[1][2][3] Its affinities (K_i) for serotonin receptors were 12 nM for the serotonin 5-HT_2A receptor, 120 nM for the serotonin 5-HT_2C receptor, 5,000 nM for the serotonin 5-HT_1B receptor, 7,100 nM for the serotonin 5-HT_1A receptor, and >10,000 nM for the serotonin 5-HT_1D receptor, whereas other serotonin receptors were not reported.^[3] Its capacity and potency in activating the serotonin receptors was also not reported.^[3]

The drug was developed by Richard Glennon and colleagues and was first described in 1990.^[3] At the time, it was described as the most 5-HT_2A receptor-selective tryptamine known to date.^[3]
