4-AcO-DMT, or 4-acetoxy-N,N-dimethyltryptamine, is a synthetic member of organic compounds known as tryptamines. Tryptamines share a core structure that consists of a bicylic indole heterocycle attached at R3 to a terminal amino group via an ethyl side chain. 4-AcO-DMT is substituted at R4 of its indole heterocycle with an acetoxy (-AcO) functional group CH3COO−. It also contains two methyl groups CH3– bound to the terminal amine RN of the ethyl side chain.
4-AcO-DMT is the acetate ester analog of psilocin (4-HO-DMT) and the N-substituted methyl homolog of 4-ACO-MET. It is the O-acetylated form of psilocin, whereas psilocybin is the O-phosphorylated form.

In the body, O-acetylpsilocin, or 4-AcO-DMT, is deacetylated to psilocin by deacetylases/acetyltransferases during first pass metabolism and during subsequent passes through the liver (evident as psilacetin is also active via parenteral routes of ingestion).
Claims of subjective differences in effects between the acetylated and non-acetylated forms of psilocin vary: some users report that O-acetylpsilocin lasts slightly longer, whilst others report that it lasts for a considerably shorter time. Many users report less body load and nausea compared with psilocin. Some users find that the visual effects produced by O-acetylpsilocin more closely resemble those produced by DMT than those produced by psilocin or psilocybin. These differences could be possible if psilacetin is psychoactive in itself and not merely as a prodrug. Despite this, there have been no controlled clinical studies to distinguish among the phenomenological effects of psilacetin, psilocin, and psilocybin.
The psychedelic effects of 4-AcO-DMT are believed to come from its activity as a partial agonist for the 5-HT2A receptor. However, the role of these interactions and how they result in the psychedelic experience is the subject of ongoing scientific investigation.
In the body, 4-AcO-DMT is suspected to be deacetylated into psilocin during first pass metabolism, by the acidic conditions in the stomach, and as it passes through the liver.
