(4-Aryl-4-hydroxypiperidinyl) alkylcarbamoyl 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.
本发明公开了(4-芳基-
4-羟基哌啶基)烷基
氨基
恶唑烷酮化合物及其药学上可接受的盐。还描述了这些化合物的合成及其作为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。这些化合物具有选择性,能够放松富含α1A受体亚型的平滑肌组织,而不会同时引起低血压。例如,这种组织在尿道周围存在。因此,本发明化合物的一种用途是帮助患有良性前列腺增生的男性获得急性缓解,使尿流受阻程度降低。本发明化合物的另一种用途是通过与人5α-还原酶
抑制剂化合物的组合使用,从而实现对良性前列腺增生影响的急性和慢性缓解。
