This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as selective alpha 1a adrenergic receptor antagonists. One application of these compounds is in the treatment of benign prostatic hyperplasia. These componds 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.
这项发明涉及某些新颖化合物及其衍
生物,它们的合成以及它们作为选择性α 1a
肾上腺素能受体
拮抗剂的用途。这些化合物的一个应用是用于治疗良性前列腺增生。这些化合物在其能够放松富含α 1a 受体亚型的平滑肌组织方面具有选择性,同时不会引起低血压。这样的组织之一就是围绕尿道内膜的组织。因此,这些化合物的一个用途是为患有良性前列腺增生的男性提供急性缓解,使尿液流动更加顺畅。这些化合物的另一个用途是与人类5-α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。
