amine-functionalised anthraquinone derivatives to determine their extent of binding to G-tetraplex DNA and their ability to inhibit the enzymes telomerase and Taq polymerase. The results are compared to data obtained from a modified TRAP assay and show good correlation between the two methods. The findings suggest that anthraquinone derivatives of this type inhibit telomerase by stabilisation of four-stranded
已经对许多胺官能化的蒽醌衍生物进行了分子建模,以确定它们与G-四链体DNA的结合程度以及它们抑制端粒酶和Taq聚合酶的能力。将结果与从改良的TRAP分析获得的数据进行比较,结果表明两种方法之间具有良好的相关性。这些发现表明这种类型的蒽醌衍生物通过稳定与富鸟嘌呤的端粒DNA区域相关的四链四链体结构而抑制端粒酶。
