Methamnetamine (also known as methylnaphetamine, MNA, MNT, MNAP, PAL-1046, and MY-10) is a triple monoamine releasing agent of the amphetamine and naphthylaminopropane families. It is the N-methyl analog of the non-neurotoxic experimental drug naphthylaminopropane and the naphthalene analog of methamphetamine. It has been sold online as a designer drug between 2015 and 2016.
Methamnetamine acts as a releasing agent of serotonin, norepinephrine, and dopamine, with EC<sub>50</sub> values of 13 nM, 34 nM, and 10 nM, respectively. It is also a lower-potency partial agonist of the serotonin 5-HT<sub>2A</sub> receptor.
Methamnetamine is illegal in Japan.
