title: Novel heterocycles as selective alpha1-adrenergic receptor antagonists.
abstract: A novel series of aryl piperazine substituted heterocycles has been synthesized and identified as antagonists of the alpha1a-adrenergic receptor (alpha1a-AR), which has been implicated in benign prostatic hyperplasia (BPH). These compounds selectively inhibit binding to the alpha1a-AR with K(i)s as low as 2.1 nM.
