Novel hybrid porphyrins bearing two and four suitably protected glycosidic units appended at the meso positions of the central macrocycle through robust carbon–carbon bonds have been constructed and characterized. Metallation of these constructs with certain bivalent metal ions then produced a series of porphyrinato entities which had all the sugar protecting groups removed to arrive at the corresponding
已经构建并表征了新型杂卟啉,其带有两个和四个经过适当保护的糖苷单元,这些糖苷单元通过强健的碳-碳键附加在中央大环的中观位置。然后用某些二价金属离子对这些构建体进行金属化,产生了一系列卟啉实体,这些实体中的所有糖保护基均被去除,从而形成了相应的水溶性卟啉-糖杂种。值得注意的是,两种钯衍生物,化合物6和10,被证明是在水性介质中于室温下暴露于可见光时,能将双链DNA选择性裂解为II型带切口环状DNA的有效试剂。
