Abstract

We have been investigated the possibility of B-Z transition in ZnTMPyP-DNA interaction based on the observation of spectroscopic data. In this study, we found drastic change in the AFM image of supercoiled plasmid DNA when it was interacted with TMPyPs indicating that the considerable amount of unwinding of double helix or B-Z transition is induced by the drug-DNA interaction. Such phenomena were not observed for other cationic drugs examined.

药物- dna相互作用的原子力显微镜。
基于光谱数据的观察,我们研究了zntmpp - dna相互作用中B-Z跃迁的可能性。在这项研究中,我们发现当超螺旋质粒DNA与TMPyPs相互作用时,其AFM图像发生了巨大变化,这表明药物-DNA相互作用诱导了相当数量的双螺旋解绕或B-Z转变。其他阳离子药物未见此现象。
