摘要: 以ALS抑制剂药效团模型为基础建立了提问结构,将药效团模型中的生物结构信息输入到多种小分子三维结构数据库(NCI-3D和ACD-3D数据库)中,分别搜寻出100多个符合特征结构信息的全新结构候选化合物.以这些命中结构的分子特征信息为基础设计合成了一系列新型的ALS抑制剂,初步生物活性测试结果表明,预期有生物活性的化合物显示出一定的ALS酶抑制剂活性.

Abstract: Derived from the postulated ALS inhibitors′ pharmacophore model, the generalized function-based queries were defined and used for three-dimensional(3D) searching in two different 3D databases(NCI-3D and ACD-3D). More than 100 novel structural hits were found by performing different 3D searching programs(3DFS and ISIS/3D). The novel structure hits provide a lot of structural information, the novel type ALS inhibitors were designed and synthesized by the information. The preliminary bioassay data indicate that some compounds with an anticipated good biological activity have ALS inhibitions in some degree.

Key words: ALS inhibitors, Pharmacophore model, Design, Synthesis, Bioactivity
