We report here the synthesis and evaluation for telomerase-inhibitory and quadruplex DNA binding properties of several rationally-designed quindoline analogues, substituted at the 2- and 7- positions. The ability of these compounds to interact with and stabilise an intramolecular G-quadruplex DNA against increases in temperature was evaluated by a fluorescence-based (FRET) melting assay. The resulting
我们在这里报告的合成和评估的几个合理设计的喹啉类似物,在2和7位取代的端粒酶抑制和四链体DNA结合特性。通过基于荧光的(FRET)熔解测定法评估了这些化合物与分子内G-四链体DNA相互作用并稳定其抵抗温度升高的能力。如在体外端粒酶TRAP测定中所测量的,发现所得的T(m)值与其抑制端粒酶的能力相关。通过分子建模方法模拟了具有四链DNA分子结构的多种化合物之间的相互作用。结论是这类化合物代表了一种新的化学类型,适合作为端粒酶抑制剂的进一步开发。
