and fragment libraries is an active area of research. The development of novel strategies to synthesise compounds with 3D character in order to expand the diversity of a fragment library was explored. A range of substituted bicyclo[2,2,1]spirooxindoles were synthesised using a Diels–Alder [4+2] cycloaddition reaction. Both diastereoisomers were isolated from the reactions and these 3D fragment scaffolds
寻找新的支架以补充当前的HTS和片段文库是一个活跃的研究领域。探索了合成具有3D特征的化合物以扩大片段文库多样性的新策略。使用Diels–Alder [4 + 2]环加成反应合成了一系列取代的双环[2,2,1] spirooxindoles。从反应中分离出两种非对映异构体,并针对结核分枝杆菌的细胞色素P450酶CYP121筛选了这些3D片段支架。鉴定出许多命中物与CYP121结合,并显示出与血红素组的I型结合相互作用。
