4-HO-MALT was not included nor mentioned in Alexander Shulgin‘s book TiHKAL (Tryptamines I Have Known and Loved).^[4] However, it has subsequently emerged as a novel designer drug.^[1] It is said to have a dose of 10 to 40 mg orally, with its effects including mild stimulation and visual changes.^[1]

4-HO-MALT acts as an agonist of the serotonin 5-HT_2A, 5-HT_2B, and 5-HT_2C receptors.^[5] It also interacts with other serotonin receptors. The drug produces the head-twitch response, a behavioral proxy of psychedelic effects, in rodents.^[5]

Analogues of 4-HO-MALT include methylallyltryptamine (MALT), 4-AcO-MALT, 5-MeO-MALT, 4-HO-DALT, 4-AcO-DALT, 4-HO-NALT, 4-HO-MiPT, 4-HO-McPT, and 4-HO-MPT, among others.
