Bioisosteric analogs of MDMA: Improving the pharmacological profile?

Three new chemical variants of MDMA—ODMA, TDMA, and SeDMA—show similar activity at serotonin, dopamine, and norepinephrine transporters but reduced activity at 5-HT2A/2B/2C receptors compared to MDMA. They also differ in liver metabolism, with N-demethylation as the only shared route and no phase II metabolites formed. TDMA showed faster clearance. The analogs interacted more weakly with organic cation transporters and plasma membrane monoamine transporter. These bioisosteres may offer therapeutic alternatives to MDMA with a reduced off-target profile, but further studies are needed to determine if they pose lower risks.
