This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as selective alpha-1C adrenergic receptor antagonists. One application of these compounds is in the treatment of benign prostatic hypertrophy. These compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha1C receptor subtype without at the same time inducing orthostatic 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.
这项发明涉及某些新型化合物及其衍生物,它们的合成以及它们作为选择性α-1C肾上腺素受体拮抗剂的用途。这些化合物的一个应用是治疗良性前列腺肥大。这些化合物在其能够放松富含α1C受体亚型的平滑肌组织方面具有选择性,同时不会引起直立性低血压。这样的组织之一是围绕尿道内衬的组织。因此,这些化合物的一个用途是通过减少阻碍尿液流动来为患有良性前列腺增生的男性提供急性缓解。这些化合物的另一个用途是与人类5α-还原酶抑制剂化合物结合,从而实现对良性前列腺增生影响的急性和慢性缓解。
