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 reductase 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治疗良性前列腺增生症。这些化合物在其选择性上具有放松充满α1a受体亚型的平滑肌组织的能力,而不会同时引起低血压。这样的组织可以在尿道内膜周围发现。因此,这些化合物的一个用途是为男性良性前列腺增生症提供急性缓解,从而使尿液流动更加顺畅。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症的急性和慢性缓解。
