Abstract: The present invention provides a novel group of active peptide compounds based on the psychoactive safrylamine compounds MDMA, MDA, MMDA-2, and MDAI. Thereby, the invention provides for improved pharmacokinetic properties during uptake of the safrylamines, as well as reduced side effects resulting from the metabolites thus formed. Due to the affinity of the novel safrylamine derivatives for the 5-HT2a-receptor, the invention can find use in numerous forms of therapy, such as against depression or posttraumatic stress disorder (PTSD).

Abstract: The present invention provides a novel group of active compounds based on the psychoactive compound psilocin. The psilocin derivatives provided herein exhibit improved pharmacokinetic properties during uptake as compared to psilocin, as well as reduced side effects resulting from the metabolites thus formed. Due to the affinity of the novel psilocin derivatives for the 5-HT2A-receptor, these derivatives are particularly advantageous for use in therapy, e.g., in the treatment of depression or drug addiction.

Abstract: The present invention provides an improved method for the production of lysergic acid diethylamide (LSD) for GMP purposes. Furthermore, the present invention provides novel LSD derivatives of formula I as well as their synthesis and purification. Due to the affinity of the presented substances for the 5-HT2A receptor, the invention may find application in numerous forms of therapy, such as against depression or drug addiction.
