N-n-Propylnorapomorphine (NPA) is an aporphine derivative dopamine agonist closely related to apomorphine.^[2]^[3] In rodents it has been shown to produce hyperactivity, stereotypy, hypothermia, antinociception, and penile erection, among other effects.^[4]^[5]^[6]^[7] Notably, its effects on locomotion are biphasic, with low doses producing inhibition and catalepsy and high doses resulting in enhancement of activity.^[8] This is likely due to preferential activation of D₂/D₃ autoreceptors versus postsynaptic receptors,^[9] the latter of which overcomes the former to increase postsynaptic dopaminergic signaling only with high doses.
