We report here that phenol derivatives with two and four quaternary ammoniums were synthesized and their abilities to bind and cross-link DNA were investigated. Thermal denaturizing studies indicated that derivatives possess similar DNA binding abilities and gel electrophoresis revealed that more charges (series B) and electronic donation substitute linkers (like –S–) dramatically increase the DNA cross-linking abilities.
我们在此报告合成了含有两个和四个季铵的苯酚衍生物,并研究了它们与 DNA 结合和交联的能力。热变性研究表明,这些衍生物具有相似的 DNA 结合能力,凝胶电泳显示,更多的电荷(B 系列)和电子捐赠替代连接体(如 -S-)可显著提高 DNA 交联能力。
Anion conductive aromatic polymers containing fluorenyl groups: Effect of the position and number of ammonium groups
Synthesis and properties of anionconductivearomatic block copolymers, QPE‐bl‐3, QPE‐bl‐3 M2, and M4, containing fluorenylidene biphenylene groups as scaffold for ammoniumgroups are described. These copolymers share the same main chain structure, but the position and the number of ammoniumgroups on a fluorenylgroup differ. High molecular weight quaternized block copolymers were obtained via typical
