O-Glutarylpsilocin (developmental code name RE109), also known as 4-glutaryloxy-N,N-dimethyltryptamine (4-HO-DMT O-glutarate) is a serotonergic psychedelic of the tryptamine family.^[1]^[2] It acts as a prodrug of psilocin (4-HO-DMT) similarly to other psilocin prodrugs like 4-AcO-DMT, 4-PrO-DMT, and psilocybin (4-PO-DMT).^[1]^[2] The drug is cleaved into psilocin by non-specific esterases.^[1]^[2] O-Glutarylpsilocin was first described in the scientific literature in 2024.^[1]^[2] It has been patented by Reunion Neuroscience.^[2] A related drug, luvesilocin (RE-104, FT-104; 4-GO-DiPT), a prodrug of 4-HO-DiPT, is being developed for potential medical use.^[1]^[2]
