that can identify full ligand structures from large‐scale DEDLs. This method is also able to convert unbiased libraries into focused ones targeting specific protein classes. We demonstrated this method by selecting DEDLs against five proteins, and novel inhibitors were identified for all targets. Notably, several selective BD1/BD2 inhibitors were identified from the selections against bromodomain 4 (BRD4)
动态组合库(DCL)是生物医学研究中配体发现的强大工具。但是,DCL的低多样性阻碍了它们的应用。最近,DCL中已经采用了DNA编码的概念来创建DNA编码的动态库(DEDL)。但是,当前所有的DEDL都仅限于片段识别,并且在选择后需要一个具有挑战性的片段链接过程。我们报告了一种锚定的DEDL方法,该方法可以从大规模DEDL中识别出完整的配体结构。这种方法还能够将无偏文库转换为针对特定蛋白质类别的集中文库。我们通过选择针对五种蛋白质的DEDLs证明了这种方法,并为所有靶标确定了新型抑制剂。值得注意的是 从针对重要的抗癌药物靶标bromodomain 4(BRD4)的选择中鉴定出了几种选择性的BD1 / BD2抑制剂。这项工作可以为抑制剂发现提供广泛适用的方法。
