The bindingmodes and binding constants for the complexes of forty types of pyridocarbazole derivatives 1–40 with double stranded DNAs (dsDNAs) were reported. The bindingmodes were determined by a combination of a deflection spectroscopy and orientation of the corresponding molecule in the DNA-based film with chain alignment. All of the compounds exhibited the intercalation-binding mode. Its binding
对于40种pyridocarbazole衍生物的复合物的结合模式和结合常数1 - 40报告,其中双链DNA的(dsDNAs)。通过偏转光谱和基于DNA的膜中相应分子的取向与链排列的组合来确定结合模式。所有化合物均表现出插层结合模式。根据吡啶并咔唑骨架上的取代基和dsDNA的序列,通过石英晶体微量天平(QCM)测定的其对于络合物的结合常数K a从1.7×10 5到4.5×10 7 M -1变化。结合常数K a具有2-(ω-氨基)烷基和5-(ω-氨基)烷基氨基甲酰基的吡啶并咔唑衍生物的“α-羟基”大于相应的ω-脲基衍生物的β-羟基。这些ω-氨基化合物在络合中表现出强烈的GC碱基对偏好。随着NaCl浓度的增加,K a值降低。通过分子模型阐明,2系ω-氨基衍生物的骨架与堆积的GC碱基对完全重叠,从而导致形成稳定的嵌入复合物,以及5系脲基的骨架衍生物半重叠导致形成不稳定的络合物。此外,ln K a
