resulting set of 80 fragments was highly three‐dimensional, and its shape diversity was significantly enriched by twenty synthesised fragments. The fragment set was screened by high‐throughput protein crystallography against Aurora‐A kinase, revealing four hits that targeted the binding site of allosteric regulators. In the longer term, it is envisaged that the fragment set could be screened against a range
从历史上看,化学家们以高度不平衡和不系统的方式探索化学空间。例如,现有片段集的形状多样性通常不会反映所有理论上可能的片段的形状多样性。为了通过实验评估增加的三维度的附加值,设计并整理了形状多样的片段集。使用市售片段并利用统一的合成方法对sp 3进行组装富含分子的支架。所得的80个片段集是高度三维的,其形状多样性被20个合成片段显着丰富。通过针对Aurora-A激酶的高通量蛋白质晶体学筛选了该片段集,揭示了四个靶向变构调节因子结合位点的命中。从长远来看,可以针对一系列功能多样的蛋白质筛选片段集,从而可以更全面地评估更多形状多样的筛选集合的附加值。
