Based on a combination of an Ugi four component reaction and a ring closing metathesis, a library of novel artificial macrocyclic inhibitors of the p53–MDM2 interaction was designed and synthesized. These macrocycles, alternatively to stapled peptides, target for the first time the large hydrophobic surface area formed by Tyr67, Gln72, His73, Val93, and Lys94 yielding derivatives with affinity to MDM2
基于Ugi四组分反应和闭环易位的组合,设计并合成了新型的人工大环抑制剂p53–MDM2相互作用的文库。这些大环化合物,除装钉肽外,首次靶向由Tyr67,Gln72,His73,Val93和Lys94形成的大疏水表面积,从而产生对纳摩尔摩尔范围内的MDM2具有亲和力的衍生物。使用荧光偏振(FP)分析和1 H – 15 N二维HSQC核磁共振实验评估了它们与MDM2的结合亲和力。
