Aleph, or Aleph-1, also known as DOT or as 4-methylthio-2,5-dimethoxyamphetamine, is a psychedelic drug of the amphetamine and DOx families.^[1]

Effects

Aleph 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 to 10 mg, with effects typically lasting for 6 to 8 hours.^[1]

Pharmacology

Like many other psychedelics, Aleph is a partial agonist at the 5-HT_2A receptor (EC₅₀ = 10 nM).^[2]^[3] 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.^[4]
