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.

关键词: M1受体激动剂, 距离比较法, 药效团模型, 数据库搜索

Not knowing the 3D structure of muscarinic receptors, the pharmacophore models of M1 agonists 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.

Key words: M1 agonist, distance comparison method, pharmacophore model, database searching
