N-n-Propylnorapomorphine (NPA) is an aporphine derivative dopamine agonist closely related to apomorphine.[1][2] In rodents it has been shown to produce hyperactivity, stereotypy, hypothermia, antinociception, and penile erection, among other effects.[3][4][5][6] Notably, its effects on locomotion are biphasic, with low doses producing inhibition and catalepsy and high doses resulting in enhancement of activity.[7] This is likely due to preferential activation of D2/D3 autoreceptors versus postsynaptic receptors,[8] the latter of which overcomes the former to increase postsynaptic dopaminergic signaling only with high doses.
