1,4-Dioxane, a Suitable Scaffold for the Development of Novel M3 Muscarinic Receptor Antagonists
摘要:
In this study the modulation of the pharmacological profile from agonist to antagonist was successfully obtained by replacing the methyl group in position 6 of the 1,4-dioxane scaffold of the potent M-2/M-3 muscarinic agonist 1 with bulkier groups. In particular, the 6,6-diphenyl substitution provided the potent M-3 preferring antagonist (+/-)-17, which in in vivo study proved to be effective in reducing the volume-induced contractions of rat urinary bladder and was devoid of cardiovascular effects.
