Lys-MDMA

Lys-MDMA, or lysine-MDMA, also known as N-(L-lysinamidyl)-MDMA, is an intended prodrug of MDMA which was being investigated for possible use as a pharmaceutical drug in the treatment of psychiatric disorders.^{[2][3][4][5][6]} Structurally, lys-MDMA is to MDMA as lisdexamfetamine is to dextroamphetamine^[5][4] As of August 2024, a phase 1 clinical trial comparing MDMA, MDA, lys-MDMA, and lys-MDA has been conducted and completed.^[2][3][6] Lys-MDMA was being developed by MindMed.^[3][6]

Close

The published phase 1 clinical trial unexpectedly found that lys-MDMA does not convert into MDMA in humans and is completely inactive.^[1] This is in contrast to lisdexamfetamine and lys-MDA, where are converted into dextroamphetamine and MDA, respectively.^[1] The lack of conversion was attributed to steric hindrance caused by the N-methyl group of lys-MDMA.^[1]
