Lactam and cyclic urea derivatives and their pharmaceutically acceptable salts 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 typically 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.
                            本文披露了内酰胺和环状
脲衍
生物及其药学上可接受的盐。还描述了这些化合物的合成方法及其用作α1a
肾上腺素受体拮抗剂的用途。这些化合物的一个应用是治疗良性前列腺增生症。这些化合物通常具有选择性,能够放松富含α1a受体亚型的平滑肌组织,同时不引起低血压。这样的组织可以在尿道内膜周围找到。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,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,从而可以实现良性前列腺增生症的急性和慢性缓解。
