摘要
在检测β-四(羧基苯氧基)锌酞菁(p-HPcZn)光敏性能的基础上,利用吸收光谱和荧光光谱分析技术研究了p-HPcZn与小牛胸腺脱氧核糖核酸(CT DNA)的相互作用机理。研究结果表明,p-HPcZn能以嵌插的形式与CT DNA发生作用;无论是在有氧或是在无氧的条件下,p-HPcZn对CT DNA的光敏损伤能力均高于血卟啉。
Based on the photosensitive properties of tetra-substituted zinc phthalocyanine (p-HPcZn), the interaction of p-HPcZn calf thymus DNA (CT DNA) was investigated by UV-Vis and fluorescence spectroscopies. It was found that p-HPcZn could insert into the double-helix of DNA. In addition, the result of CT-DNA photodamage experiments suggests that the photodamage ability of p-HPcZn is higher than that of hematoporphyrin in the presence or absence of oxygen .
