4-Hydroxy-3-methoxymethamphetamine (HMMA ) is an active metabolite of 3,4-methylenedioxymethamphetamine (MDMA).[ 1] [ 2] [ 3] It is a slightly more potent stimulant than MDMA in rodents.[ 4] The drug is substantially less potent than MDMA as a monoamine releasing agent in vitro .[ 5] [ 6] Nonetheless, HMMA has been found to induce the release of serotonin , norepinephrine , and dopamine with EC50 Tooltip half-maximal effective concentration values of 589 nM, 625 nM, and 607–2884 nM, respectively, and hence acts as a lower-potency serotonin–norepinephrine–dopamine releasing agent (SNDRA).[ 5] [ 6] The predicted log P of HMMA is 1.2.[ 7]
