依次利用2-萘酚、1,6-二溴己烷、和厚朴酚, 对2-硝基-5,10,15,20-四苯基卟啉及其金属配合物进行结构修饰, 首次得到四对同分异构体桥连卟啉光敏剂, 目标产物经UV-vis, 1H NMR, H-H COSY, IR, MS, 元素分析等表征. 以1,3-二苯基异苯并呋喃(DPBF)为猝灭剂测定了桥连卟啉产生单线态氧的能力; 采用凝胶电泳和紫外-可见光谱滴定法, 初步考察了化合物对pBR322 质粒DNA 的光敏切割能力及其与小牛胸腺DNA 的作用模式.

Four pairs of porphyrin isomers have been synthesized by reaction of 2-nitrotetraphenylporphyrin and its metallic complexes with 2-naphthol, 1,6-dibromohexane and honokiol respectively, and structurally characterized by UV-vis, 1H NMR, H-H COSY, IR, MS, and elementary analysis. The production of singlet oxygen under radiation was determined with DPBF as the quencher. Their photocleavage ability to pBR322 plasmid DNA has been tested by gel electrophoresis and the interaction with CT DNA was detected by UV-Vis spectroscopy preliminarily.

Key words: porphyrin, honokiol, synthesis, characterization, photosensitivity
