Scientists Publish the Crystal Structure of 4-AcO-DMT Fumarate

This is the crystal structure of the fumarate salt of psilacetin which was described by David Nichols and Steward Frescas of Purdue University in 1999.

The study reports that 4-AcO-DMT fumarate (aka psilacetin fumarate) is an asymmetric unit consisting of one 4-acetoxy-N,N-dimethyltryptammonium cation, and one 3-carboxyacrylate anion. The discovery of this structure is important because the body metabolizes psilacetin to psilocin, making psilacetin an alternative to using psilocybin in studies and clinical trials. Also, psilacetin is easier and less expensive to synthesize than psilocybin.
