Novel oxazolidinone compounds and pharmaceutically acceptable salts thereof are disclosed. The synthesis of these compounds and their use as alpha 1a adrenergic receptor antagonists is also described. 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 can be achieved.
披露了新型恶唑烷酮化合物及其可药用的盐。这些化合物的合成及其作为α1a肾上腺素能受体拮抗剂的使用也进行了描述。这些化合物的一个应用是治疗良性前列腺增生。这些化合物在选择性地放松富含α1a受体亚型的平滑肌组织的能力方面是特异的,同时不引起低血压。这样的组织之一位于尿道内衬周围。因此,这些化合物的一个用途是为准切缓解患有良性前列腺增生的男性的症状,通过允许更顺畅的尿液流动。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使用,从而使良性前列腺增生的急性症状和慢性症状均可得到缓解。
