据报道,钴 (III) 与八种不同的 1,4,7,10-四氮杂环十二烷 (cyclen) 以及两种三 (3-氨基丙基) 胺 (trpn) 衍生物之间的配合物在其侧链中具有不同数量和结构的全烷基铵基团。配体。额外正电荷的存在对硝基苯基和双(硝基苯基)磷酸酯的水解速率影响很小,但会显着增强质粒 DNA 的裂解。增加带电侧基的数量和/或它们与金属离子中心的距离可以更好地与 DNA 凹槽结合,如小牛胸腺 DNA 的亲和力测量所示。与此一致,质粒 DNA 切割的饱和动力学导致 Michaelis-Menten 型 KM 值的效率相应增加,kcat 参数相当恒定。

A novel process of manufacturing sevelamer carbonate from a polyallylamine carbonate or bicarbonate chloride salt. Process for manufacture of carbonate and/or bicarbonate salts of water insoluble polymers containing amino groups that are useful as anion binders in the gastrointestinal (GI) system. The process arranges the polyallylamine chain in a solution in such a way that the cross-linking reaction with epichlorohydrin can be controlled at a desired reaction rate.
