4-Acyloxytryptamines

'4-Acetoxy-N,N-dimethyltryptamine (4-AcO-DMT or 4-acetoxy-DMT), also known as O-acetylpsilocin or psilacetin', is a psychedelic drug of the tryptamine family related to psilocybin and psilocin. It is a synthetic derivative of psilocin (4-HO-DMT) in which the hydroxyl group has been acetylated, and is the analogue of psilocybin (4-PO-DMT) in which the phosphate ester has been replaced with an acetate ester. The drug is a prodrug of psilocin and is used orally similarly to psilocybin.

4-AcO-DET, also known as '4-acetoxy-N,N-diethyltryptamine as well as ethacetin or ethylacybin', is a psychedelic tryptamine. It was first synthesized in 1958 by Albert Hofmann in the Sandoz lab.

4-AcO-DiPT, also known as '4-acetoxy-N,N-diisopropyltryptamine or as ipracetin', is a psychedelic drug of the tryptamine and 4-hydroxytryptamine families related to 4-AcO-DMT (psilacetin). It is taken orally.

4-AcO-MiPT, also known as '4-acetoxy-N-methyl-N-isopropyltryptamine or as mipracetin', is a psychedelic tryptamine. It is closely related to 4-AcO-DMT and methylisopropyltryptamine (MiPT).

4-AcO-DALT, also known as '4-acetoxy-N,N-diallyltryptamine or as dalcetin', is a tryptamine derivative. It has been sold as a designer drug, but little other information is available. It was first officially identified in seized drug samples in 2012.
