fluorescent intercalator displacement (FID), electrospray ionization mass spectrometry (ESI‐MS), and circular dichroism (CD) spectroscopy. The preferred compounds have high aqueous solubility and are strong and potent G4 binders with a high selectivity over duplex DNA; thus, they represent a significant improvement over the lead compounds. Two of the compounds are inhibitors of HeLa and HT1080 cell proliferation
能够稳定G-四链体(G4)结构的小分子对于开发改良的抗癌药物很重要。设计了代表已知菲咯啉基配体杂化结构的新型4,7-二氨基取代的1,10-菲咯啉-2,9-二甲酰胺。已开发出一种有效的化合物合成路线,并已通过Förster共振能量转移(FRET)熔解测定,荧光嵌入剂置换(FID),电喷雾电离质谱(ESI-MS)和环形测定了它们与各种G4序列的相互作用二向色(CD)光谱。优选的化合物具有高的水溶性,并且是强效的G4结合剂,对双链DNA具有高选择性。因此,它们代表了对先导化合物的重大改进。
