ne scaffold was further explored to provide dual acting α1- and AT1-receptor antagonists by synthesizing a series of derivatives and biologically evaluating the newly synthesized compounds. Based on the biological data of the current compounds and the earlier reported compounds, pharmacophore models were developed for α1- and AT1-receptor antagonist activities. Subsequently, 3D-QSAR models were also
6,7-二甲氧基支架进一步探索了α提供双重作用的1 -和AT 1通过合成一系列衍生物和生物学评价新合成的化合物受体拮抗剂。根据目前的化合物的生物数据和此前报道的化合物,药效模型,用于开发α 1 -和AT 1-受体拮抗剂的活性。随后,还导出了两种受体的拮抗作用的3D-QSAR模型。使用各种统计参数对开发的3D-QSAR模型进行了验证,并且使用特拉唑嗪和哌唑嗪作为外部化合物进一步验证了两种开发模型。对接研究证实受体-配体稳定平衡-双活性拮抗剂(的相互作用110在两个α的活性位点)1 -以及AT 1 -受体,这些都是由同源性建模所获得的结构。两个(42和110从新合成的衍生物的化合物的)所提供的最高效力(p阿2为α 1=分别为9.45和8.77,以及AT 1分别为8.36和8.60),并且两个受体的平衡调节。既发现本化合物是特拉唑嗪略小有力作为α 1 -拮抗剂和等效氯沙坦如AT 1 -拮抗剂在体内动物模型。
