title: Novel arylpiperazines as selective alpha1-adrenergic receptor antagonists.
abstract: A novel series of arylpiperazines has been synthesized and identified as antagonists of alpha1a adrenergic receptor (alpha1a-AR) implicated in benign prostatic hyperplasia. These compounds selectively bind to membrane bound alpha1a-AR with K(i)s as low as 0.66 nM. As such, these potentially represent a viable treatment for BPH without the side effects associated with known alpha1-adrenergic antagonists.
