Abstract
The structure-activity relationships of novel 1,5-benzodioxepin derivatives as muscarinic M(1)-M(3) receptor antagonists are reported. Some of these compounds were found to possess high binding affinity for the muscarinic M(3) receptor and potent effect on rhythmic increase in bladder pressure in unanesthetized rats following oral administration. These compounds displayed selectivity for the bladder over the salivary gland.
