PCT No. PCT/US96/02534 Sec. 371 Date Aug. 13, 1997 Sec. 102(e) Date Aug. 13, 1997 PCT Filed Feb. 23, 1996 PCT Pub. No. WO96/25934 PCT Pub. Date Aug. 29, 1996This invention relates to novel compounds, their synthesis and use as selective alpha 1a adrenergic receptor antagonists. One application of the compounds is in the treatment of benign prostatic hyperplasia. The compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia are achieved.
