Disclosed are chelating co-polymer compositions that are soluble in aqueous media and chelate essential metals, methods of preparation and uses thereof. The chelating compositions are comprised of two or more different monomers, at least one of which possesses metal binding or metal chelating activity. The chelating compositions are synthesized by reversible addition-fragmentation transfer (RAFT) polymerization with the aid of a suitable RAFT-mediating agent. Also described are chelating compositions that comprise hydroxypyridinone chelating groups. The ability of the chelating compositions to bind metals affects the activity of a living cells and organisms, which require the metals for cellular functions.
本发明公开了可溶于水介质并能螯合必需金属的螯合共聚物组合物及其制备方法和用途。螯合组合物由两种或两种以上不同的单体组成,其中至少一种单体具有金属结合或金属螯合活性。螯合组合物是在适当的 RAFT 媒介剂的帮助下,通过可逆加成-碎片转移(RAFT)聚合反应合成的。还描述了包含羟基吡啶酮螯合基团的螯合组合物。螯合组合物结合金属的能力会影响活细胞和生物体的活性,因为活细胞和生物体的细胞功能需要金属。
