GZ-793A inhibits methamphetamine-evoked dopamine release from synaptic vesicles through a surmountable allosteric mechanism and interacts with several sites on the vesicular monoamine transporter-2 (VMAT2), including high- and-low affinity intravesicular dopamine release sites, high-affinity extravesicular dopamine uptake sites and low-affinity extravesicular dihydrotetrabenazine binding sites. VMAT2 interactions likely underlie the ability of GZ-793A to attenuate the neurochemical and behavioral effects of methamphetamine.
