The work demonstrated that the linkage structure between fluorescent and di(triazole-[12]aneN3) played the important role for their gene delivery performance, and that ANQ-A-M represents a vector with the strong transfection efficiency in vitro and in vivo as well as the efficient real time bioimaging properties, which is potential

AM和ANQ-HM在 420 nm 处显示出相同的最大吸收,并且它们在 650 nm 附近的荧光强度在不同溶剂中有所不同,并且在质子溶剂中变得很差。凝胶电泳分析表明,在
DOPE 存在下,这两种化合物在 20 μM 时完全阻止了 pDNA 的迁移。然而,与ANQ-HM的 DNA 缩合是不可逆的,从
