[{"from": "human", "value": "Create a molecule with the structure as the one described. The molecule is a synthetically-derived form of the endogenous alkaloid isolated from the plant Atropa belladonna.  Atropine functions as a sympathetic, competitive antagonist of muscarinic cholinergic receptors, thereby abolishing the effects of parasympathetic stimulation.  This agent may induce tachycardia, inhibit secretions, and relax smooth muscles.
