IUPAC Name: (6R,6aS,7S,9R,11S)-7-ethyl-3-methoxy-6,6a,7,8,9,10,12,13-octahydro-5H-6,9-methanopyrido[1',2':1,2]azepino[4,5-b]indole
InChIKey: UCIDWKVIQZIKEK-CFDPKNGZSA-N
SMILES: CC[C@@H]1[C@@]2([H])[C@]3([H])C4=C(CC[N@]2C[C@@](C1)([H])C3)C5=CC=C(OC)C=C5N4
Biological Activity: Tabernanthine is a negative chronotropic and negative inotropic agent that selectively acts on sinoatrial node receptors, regulating heart rhythm and myocardial contractility. Tabernanthine exhibits atropine resistance and direct non-cholinergic binding properties, acting directly on the sinoatrial node rather than relying on vagal nerve or cholinergic pathways to exert its key activity of slowing heart rate and weakening myocardial contractility. Tabernanthine is useful in cardiovascular pharmacology research, particularly in the areas of sinoatrial node function regulation, mechanisms related to bradycardia, and studies of cardiac receptor subtype differences[1].
