In this work, we have characterized the interactions of monospermine porphyrin derivative with calf thymus DNA (ct‐DNA) and poly (dG‐dC)2 in both B and Z conformation. By several spectroscopic techniques (UV–vis, electronic circular dichroism and resonance light scattering), the binding modes of monospermine porphyrin derivative with different DNA sequences have been elucidated. In the presence of ct‐DNA, the porphyrin binds along the external double helix as well as in the presence of B conformation of poly (dG‐dC)2. Whilst when the Z form of the poly (dG‐dC)2 is induced, a slight intercalation of the porphyrin between the basis has been detected.

单精胺卟啉衍生物与DNA的相互作用。

在这项工作中,我们表征了单精胺卟啉衍生物与小牛胸腺DNA(ct-DNA)和聚(dG-dC)2在B和Z构象中的相互作用。通过几种光谱技术(紫外可见光谱,电子圆二色性和共振光散射),阐明了单精胺卟啉衍生物与不同DNA序列的结合方式。在存在ct-DNA的情况下,卟啉沿着外部双螺旋结合,并且在poly(dG-dC)2的B构象存在下。当诱导Z形式的聚(dG-dC)2形成Z时,已检测到碱之间存在少量的卟啉插入。
