This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as alpha 1a adrenergic receptor antagonists. One application of these compounds is in the treatment of benign prostatic hyperplasia. These 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 relductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia are achieved.
本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α1a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症。这些化合物在其选择性方面表现出能够松弛α1a亚型丰富的平滑肌组织,而不会同时引起低血压。这样的组织包括围绕尿道内膜的组织。因此,本发明化合物的一个应用是通过允许更畅通的尿液流动,为患有良性前列腺增生症的男性提供急性缓解。本发明化合物的另一个应用是与人类5α-还原酶抑制剂化合物结合,从而实现对良性前列腺增生症的急性和慢性缓解。
