structure‐guided selection of fragments was used to identify three unexplored classes of human DHODH inhibitor compounds: 4‐hydroxycoumarins, fenamic acids, and N‐(alkylcarbonyl)anthranilic acids. Structure‐guided selection of fragments targeting the inner subsite of the DHODH ubiquinone binding site made these findings possible with screening of fewer than 300 fragments in a DHODH assay. Fragments from the
结合虚拟筛选和片段结构指导选择的策略,用于鉴定人类DHODH抑制剂化合物的三类未经探索的类别:4-羟基香豆素,芬那酸和N- (烷基羰基)邻氨基苯甲酸。通过结构导向的靶向DHODH泛醌结合位点内部亚位片段的选择,通过在DHODH分析中筛选不到300个片段,使这些发现成为可能。随后将鉴定出的三种抑制剂类别的片段进行化学扩增,以靶向另一个具有疏水特性的亚位点。发现这三个类别在扩展时都表现出不同的结构-活动关系。小说N‐(烷基羰基)邻氨基苯甲酸类别显示出对人DHODH最有前途的效价,IC 50值在低纳摩尔范围内。给出了与此类抑制剂复合的人DHODH的结构。
