Synthesis and antimuscarinic activity of a series of 4-(1-imidazolyl)-2, 2-diphenylbutyramides: discovery of potent and subtype-selective antimuscarinic agents
In a study directed toward the development of new, selective agents with potential utility in the treatment of altered smooth muscle contractility and tone, for example, as seen in urinary incontinence associated with bladder muscle instability, a series of 4-(1-imidazolyl)-2, 2- diphenylbutyramide derivatives was prepared. These compounds were examined for M1, M2, and M3 muscarinic receptor subtype selectivity in isolated tissue assays. The ...
