A series of conformationally restricted acetanilides were synthesized and evaluated as beta(3)-adrenergic receptor agonists (beta(3)-AR) for the treatment of overactive bladder (OAB). Optimization studies identified a five-membered ring as the preferred conformational lock of the acetanilide. Further optimization of both the aromatic and thiazole regions led to compounds such as 19 and 29, which have a good balance of potency and selectivity. These compounds have significantly reduced intrinsic clearance compared to our initial series of pyridylethanolamine beta(3)-AR agonists and thus have improved unbound drug exposures. Both analogues demonstrated dose dependent beta(3)-AR mediated responses in a rat bladder hyperactivity model.
