距离比较法构建M1受体激动剂药效团模型
Construction of the Pharmacophore Models of M1 Receptor Agonists by Distance Comparison Method
【摘要】 在M1受体三维结构未知的情况下,利用距离比较法(DISCO)对24个具有M1受体激动活性的化合物进行了研究,构建了M1受体激动剂可能的药效团模型,为设计新M1受体激动剂提供了参考,并以此为提问结构在ACD数据库和中草药数据系统(TCMDB)中进行搜索,得到一系列结构新颖并可能具有M1激动活性的化合物.
【Abstract】 Not knowing the 3D structure of muscarinic receptors, the pharmacophore models of M1 ago-nists were constructed using 24 M1 receptor agonists by distance comparison method, providing a reference for designing new M1 agonists. A set of possible M1 agonists to be novel in structure were selected by searching ACD and TCMDB databases with the attained model as a query.
