cyanoacetic acid. The synthesized compounds were electrostatically conjugated to gold and/or silver nanoparticles in dimethylsulfoxide and were examined as photosensitizers for photodynamic therapy (PDT). The PDT activity of the formazan derivatives alone and conjugated with metal nanoparticles was investigated against HL-60 cells under dark and light conditions. Formazan derivatives and their conjugates showed
摘要合成了一系列的1,5-双(4-芳基/杂基)-3-氰基甲酰胺衍生物,并通过光谱分析对其进行了表征。合成策略涉及不同芳基(杂基)重氮盐与氰基乙酸的简单,实用的重氮偶合。将合成的化合物与二甲基亚砜中的金和/或银纳米粒子静电结合,并作为光敏剂用于光动力疗法(PDT)。研究了单独的甲maz衍生物和与金属纳米粒子结合的甲P衍生物在黑暗和明亮条件下对HL-60细胞的PDT活性。甲derivatives衍生物及其结合物在与它们的结构有关的黑暗和明亮条件下显示出可变的有希望的抗癌活性。 图形概要
