Nornuciferine, also known as 15781 or as 1,2-dimethoxynoraporphine, is a noraporphine alkaloid found in Nelumbo nucifera and a serotonin 5-HT2C receptor agonist related to the aporphine alkaloid nuciferine.[1] [2] It is the N-desmethyl analogue of nuciferine.[1] [2] The drug has been found to act as a selective partial agonist of the serotonin 5-HT2C receptor, with an EC50 Tooltip half-maximal effective concentration of 653nM and an Emax Tooltip maximal efficacy of 66% in terms of Gq signaling.[1] Conversely, it was inactive as an agonist of the serotonin 5-HT2A and 5-HT2B receptors, but did show weak antagonism of these receptors at high concentrations.[1] The serotonin 5-HT2C receptor agonism of nornuciferine was described by Bingjie Zhang and colleagues in 2020.[1]
