heterocycles have been designed and synthesized as G-quadruplex DNA stabilizers. Ten compounds were evaluated for the in vitro anticancer activity against 60 human tumor cell lines panel, four of them showing a very good inhibitory activity on several cell lines. To assess the ability of the most active compounds to interact with G-quadruplex DNA (G4-DNA), circular dichroism experiments were performed. The
已经设计并合成了十五个在2和9位通过具有不同杂环的酰胺键双取代的新的1,10-菲咯啉作为G-四链体DNA稳定剂。评价了十种化合物对60种人类肿瘤细胞系的体外抗癌活性,其中四种对几种细胞系表现出非常好的抑制活性。为了评估最具活性的化合物与G-四链体DNA(G4-DNA)相互作用的能力,进行了圆二色性实验。从热变性实验已显示出化合物稳定G4-DNA的效力。理论上通过分子对接研究了化合物与DNA和G4-DNA的结合机理。 实验结果表明,带有两个吡啶-3-基残基(甲基化和非甲基化)的两种化合物具有出色的抗癌活性,可以用作选择性G-四链体粘合剂。
