  Design and Synthesis of Novel α_1a Adrenoceptor-Selective Antagonists. 1. Structure−Activity Relationship in Dihydropyrimidinones

  摘要：

  Dihydropyrimidinones such as compound 12 exhibited high binding affinity and subtype selectivity for the cloned human alpha(1a) receptor. Systematic modifications of 12 led to identification of highly potent and subtype-selective compounds such as (+)-30 and (+)-103, with high binding affinity (K-i = 0.2 nM) for alpha(1a) receptor and greater than 1500-fold selectivity over alpha(1b) and alpha(1d) adrenoceptors. The compounds were found to be functional antagonists in human, rat, and dog prostate tissues. Compound (+)-103 exhibited excellent selectively to inhibit intraurethral pressure (IUP) as compared to lowering diastolic blood pressure (DBP) in mongrel dogs (K-b(DBP)/K-b(IUP) = 40) suggesting uroselectivity for alpha(1a)-selective compounds.

  口服生物利用的4-甲基杂芳基二氢嘧啶类乙型肝炎病毒衣壳抑制剂的设计与合成

  摘要：

  靶向乙型肝炎病毒（HBV）的衣壳蛋白，从而中断正常的衣壳形成，一直是阻止HBV病毒复制的有吸引力的方法。我们基于杂芳基二氢嘧啶（HAP）类似物Bay41-4109（1）进行了多维结构优化，并确定了一系列新的HBV衣壳抑制剂，这些抑制剂显示出有希望的细胞选择性指数，代谢稳定性和体外安全性。在这里，我们公开了与HBV衣壳蛋白复合的设计，合成，结构-活性关系（SAR），共晶结构以及4-甲基HAP类似物的体内药理研究。特别是，（2 S，4 S）-4,4-二氟脯氨酸取代的类似物34a 证明了高口服生物利用度和肝暴露，并在水动力注射（HDI）HBV小鼠模型中实现了超过2 log的病毒载量减少。

  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颖化合物及其衍生物，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。这些化合物在其能够放松富含α1a受体亚型的平滑肌组织方面具有选择性，同时不会引起低血压。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通过减少尿液流动的阻碍，为患有良性前列腺增生的男性提供急性缓解。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影响的急性和慢性缓解。
