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.
这项发明涉及某些新化合物及其衍生物,它们的合成以及它们作为α1a肾上腺素受体拮抗剂的用途。这些化合物的一个应用是用于治疗良性前列腺增生症。这些化合物在选择性上能够放松α1a受体亚型富集的平滑肌组织,同时不引起低血压。这样的组织之一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症的男性提供急性缓解,从而减轻尿液流动受阻。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,以实现对良性前列腺增生症影响的急性和慢性缓解。
