G-quadruplexes (G4) are stacked non-canonical nucleic acid structures found in specific G-rich DNA or RNA sequences in the human genome. G4 structures are liable for various biological functions; transcription, translation, cell aging as well as diseases such as cancer. These structures are therefore considered as important targets for the development of anticancer agents. Small organic heterocyclic
G-四链体(G4)是在人类基因组中特定的富含G的DNA或RNA序列中发现的堆叠的非规范核酸结构。G4结构负责各种生物学功能;转录,翻译,细胞衰老以及癌症等疾病。因此,这些结构被认为是开发抗癌剂的重要靶标。众所周知,小的有机杂环分子靶向并稳定G4结构。在本文中,我们设计并合成了2,6-二-(4-氨基甲酰基-2-喹啉基)吡啶衍生物,并通过FRET熔解法确定了其稳定G4结构的能力。已经确定这些配体对G4具有比双链体更高的选择性,并显示出对平行构象的偏好。下一个,使用三种细胞系(K562,MyLa和MV-4-11)评估了端粒酶抑制能力,对于最有效的配体1c,端粒酶活性在0.1μM浓度下不再检测到。还测试了最有前途的G4配体对两种人类髓样白血病细胞系HL60和K562的抗增殖活性。
