microorganisms has been investigated in solution and after deposition on a cotton fabric. For the first time, 1,8-naphthalimide derivatives have been tested as active components in antibacterial photodynamic therapy. To clarify the dendrimer effect, the results obtained were compared with those from two monomeric 1,8-naphthalimides (1 and 2) containing the same substitutes in the chromophore system. Cytotoxicity
通过对第一代聚丙烯胺树状聚合物的外围修饰,两个新的光敏树状聚合物包含4-二甲基氨基-1,8-萘二甲酰亚胺(3)和3-溴-4-二甲基氨基-1,8-萘二甲酰亚胺(4)),已获得。在两种有机溶剂中研究了这些树枝状聚合物的光物理和光谱特性。我们发现它们吸收可见光谱区域的光并发出黄绿色荧光。在溶液中和沉积在棉织物上之后,已经研究了树枝状大分子对病原微生物的抗菌活性。首次将1,8-萘二甲酰亚胺衍生物作为抗菌光动力疗法中的活性成分进行了测试。为了阐明树枝状聚合物的作用,将所得结果与发色团体系中含有相同取代基的两种单体1,8-萘二甲酰亚胺(1和2)的结果进行了比较。还评估了树状聚合物的细胞毒性和抗病毒活性。
