18-Methoxycoronaridine
18-Methoxycoronaridine ((-)-18-Methoxycoronaridine) is an orally active and selective α3β4 nicotinic acetylcholine receptor (nAChR) antagonist. 18-Methoxycoronaridine is an inhibitor of serotonin transporter (SERT) and norepinephrine transporter (NET), with IC50 values of 51.6 μM and 121 μM for SERT and NET, respectively. 18-Methoxycoronaridine inhibits the function of SERT and NET, promotes 5-HT3A receptor desensitization, blocks α3β4 nAChR, and modulates receptor signaling pathways associated with reinforcement. 18-Methoxycoronaridine also exhibits potent antiparasitic activity. 18-Methoxycoronaridine can be used in research related to depression, obesity, alcoholism, smoking addiction, and cutaneous leishmaniasis.
