Abstract
CD and uv-visible absorption studies with several tetracationic water-soluble porphyrin derivatives show that some of these species can serve as probes to discriminate between A- and B-conformational forms of single-stranded polynucleotides. It is also observed that these porphyrins can participate in the formation of double helices by forming transient intermediate complexes en-route to duplex formation.
摘要
对几种四阳离子水溶性卟啉衍生物进行的圆二色光谱（CD）和紫外可见吸收研究表明，其中一些物种可作为探针，用于区分单链多核苷酸的A构象和B构象形式。还观察到，这些卟啉可以通过在双链形成过程中形成瞬态中间体复合物来参与双螺旋的形成。
