Abstract:
A series of alpha1a receptor antagonists derived from a 4-aryl-3,4-dihydropyridine-2-one heterocycle is disclosed. Potency in the low nanomolar to picomolar range along with high selectivity was obtained. In vivo efficacy in a prostate contraction model in rats was observed with a few derivatives.
