4,5-MDO-DMT
4,5-MDO-DMT, or 4,5-methylenedioxy-N,''N-dimethyltryptamine, is a lesser-known psychedelic drug of the tryptamine family. It is the 4,5-methylenedioxy derivative of dimethyltryptamine and is an analogue of psilocin and 5-MeO-DMT. The drug was included as an entry in Alexander Shulgin's 1997 book TiHKAL'', but it was not tested to determine its psychoactive effects and its dose and duration are unknown. Studies in rodents found that its potential hallucinogenic potency is less than that of 4,5-MDO-DiPT but greater than that of 5,6-MDO-DiPT. Its chemical synthesis has been described. 4,5-MDO-DMT was first described in the scientific literature by Toni B. Kline and colleagues in 1982.
