Aleph (also known as DOT or 2,5-dimethoxy-4-methylthioamphetamine) is a psychedelic hallucinogenic drug and a substituted amphetamine of the phenethylamine class of compounds, which can be used as an entheogen. It was first synthesized by Alexander Shulgin, who named it after the first letter of the Hebrew alphabet. In his book PiHKAL, Shulgin lists the dosage range as 5–10 mg, with effects typically lasting for 6 to 8 hours.^[1]

Like many other psychedelics, aleph is a partial agonist at the 5-HT_2A receptor (EC₅₀ = 10 nM).^[2] It has weak MAO-A inhibitory activity with an IC₅₀ of 5.2 μM. For reference, amphetamine has an IC₅₀ of 11 μM and 4-methylthioamphetamine has a value of 0.2 μM.^[3] A lower number indicates stronger inhibition.
