landscape of two AuI/N‐heterocyclic carbene complexes interacting with G‐quadruplexes, namely a humantelomeric (hTelo) and a promoter sequence (C‐KIT1), are studied here for the first time by metadynamics. The theoretical results are validated by FRET DNA melting assays and provide an accurate estimate of the absolute gold complex/DNA binding free energy. This advanced in silico approach is valuable to
此处首次通过元动力学研究了两个与G-四链体相互作用的Au I / N-杂环卡宾配合物的结合模式和自由能态,即人端粒(hTelo)和启动子序列(C-KIT1)。 。理论结果已通过FRET DNA熔解实验验证,并提供了绝对金络合物/ DNA结合自由能的准确估计。这种先进的计算机方法对于实现选择性G4粘合剂的合理药物设计非常有价值。
