G-Quadruplex DNA结构已被证明是小分子有机化合物的结合靶点,因此被认为是有前途的药理学靶点。顺铂是一种广泛使用的化疗药物,靶向双链体DNA,最近显示也与G-四链体反应,这意味着顺铂实际上也可能靶向G-四链体。在这项工作中,我们采用磁镊研究顺铂对单个人端粒G-四链体折叠动力学的影响。结果表明,顺铂和G-四链体以两种不同的竞争方式相互作用,这取决于顺铂的浓度。
G-Quadruplex DNA structure has been proven to be a binding target for small molecular organic compounds and hence regarded as a promising pharmacological target. Cisplatin is a widely used chemotherapy drug that targets duplex DNA and was recently shown to react also with G-quadruplex, implying that cisplatin actually may also target G-quadruplex. In this work, we employed magnetic tweezers to investigate the influence of cisplatin on the folding kinetics of single human telomeric G-quadruplex. It was revealed that cisplatin and G-quadruplex interact in two different and competitive ways that depend on cisplatin concentration.
