N,N-Diallyltryptamine (DALT) is a tryptamine derivative which has been identified as a new psychoactive substance. [2] [3] It has been used as an intermediate in the preparation of radiolabeled diethyltryptamine. [4]

Use and effects

According to Alexander Shulgin in TiHKAL , the dosage of DALT is >40 mg orally and its duration is unknown. [1] Its effects have not been described. [1] According to Stephen Szara and colleagues however, DALT and other extended N,N-dialkyltryptamines produce similar effects to dimethyltryptamine (DMT) but are longer-lasting, with durations of up to 3 hours. [1] [5] [6]

Notes: The smaller the value, the more avidly the drug binds to the site. All proteins are human unless otherwise specified. Refs: [7] [8] [9] [10]

The receptor interactions of DALT have been studied. [7] [8] [9] [10] The drug produces the head-twitch response, a behavioral proxy of psychedelic effects, in rodents. [11]

History

DALT was first described in the scientific literature by Stephen Szara and colleagues by 1962. [5] [6]

Other N,N-dialkyltryptamines produce similar effects to DMT in man, though their persistence is somewhat greater, with hallucinations lasting for up to 3 hours (Szara and Hearst, 1962). These include the N,N-diethyl (DET, 4.8), N,N-dipropyl (4.9), and N,N-diallyl (4.10) compounds, none of which are found in nature.
