Amiflamine (FLA-336) is a reversible inhibitor of monoamine oxidase A (MAO-A), thereby being a RIMA, and, to a lesser extent, semicarbazide-sensitive amine oxidase (SSAO), as well as a serotonin releasing agent (SRA).[1][2][3][4] It is a derivative of the phenethylamine and amphetamine chemical classes.[1] The (+)-enantiomer is the active stereoisomer.[2]

Amiflamine shows preference for inhibiting MAO-A in serotonergic relative to noradrenergic and dopaminergic neurons.[5][6] In other words, at low doses, it can be used to selectively inhibit MAO-A enzymes in serotonin cells, whereas at higher doses it loses its selectivity.[5][6] This property is attributed to amiflamine's higher affinity for the serotonin transporter over the norepinephrine and dopamine transporters, as transporter-mediated carriage is required for amiflamine to enter monoaminergic neurons.[6]
