[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is a benzhydryl compound and a muscarinic receptor antagonist possessing both antimuscarinic and antispasmodic properties. Both tolterodine and its active metabolite, 5-hydroxymethyltolterodine, competitively blocks muscarinic receptors, thereby inhibiting acetylcholine binding. This antagonistic action results in an increase in residual urine, reflecting an incomplete emptying of the bladder, and a decrease in detrusor pressure, indicating an antimuscarinic action on the lower urinary tract. The 5-hydroxymethyl metabolite appears to contribute significantly to the therapeutic effects."}, {"from": "gpt", "value": "[C][C][=C][C][=Branch1][=Branch2][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][O][C@H1][Branch1][S][C][C][N][Branch1][=Branch1][C][Branch1][C][C][C][C][Branch1][C][C][C][C][=C][C][=C][C][=C][Ring1][=Branch1]"}]
