4-ACO-DMT, O-Acetylpsilocin is a synthetically potentially useful alternative to psilocybin for pharmacological studies, as they are both believed to be prodrugs of psilocin.
4-ACO-DMT (also known as O-Acetylpsilocin, 4-Acetoxy-DMT, or Psilacetin) is a synthetically produced psychedelic tryptamine. It is the acetylated form of the psilocybin mushroom alkaloid psilocin and is a lower homolog of 4-AcO-DET, 4-AcO-MiPT and 4-AcO-DiPT. The compound has been suggested by David Nichols to be a potentially useful alternative to psilocybin for pharmacological studies as they are both believed to be prodrugs of psilocin. Its structural similarities to psilocin and psilocybin results in an identical subjective effect profile and the three compounds can be said to feel indistinguishable from each other. This allows 4-AcO-DMT to function as a perfect substitute for psilocybin mushrooms.
44-ACO-DMT and several other esters of psilocin were originally patented on January 16, 1963 by Sandoz Ltd. via Albert Hofmann & Franz Troxler. Despite this fact, 4-AcO-DMT remains a psychedelic with a limited history of use prior to its release as a grey area compound on the online research chemical market.
