The present technology provides new compositions comprising at least one cross-linked co-polymer. In some embodiments, the polyacrylamide co-polymer comprises water soluble subunits, cross-linking subunits, and iron chelating subunits. In other embodiments, the co-polymer comprises water soluble units, cross-linking subunits, and substituted subunits, which can be conjugated with iron-chelating agents. When these new particles are exposed to certain environments, such the presence of strong acids or oxidation agents, these particles are capable of breaking up so that the iron chelating agents can chelate iron or other metals from their environments. Methods to prepare these new compositions are also provided. These compositions or compositions comprising nanogels of the present technology may be used to treat metal overload conditions such as iron overload resulting from chronic transfusions.
目前的技术提供了包含至少一种交联共聚物的新组合物。在某些实施例中,聚丙烯酰胺共聚物包括水溶性亚基、交联亚基和铁螯合亚基。在其他实施例中,共聚物包括水溶性单元、交联亚基和取代亚基,这些亚基可以与螯合铁的试剂结合。当这些新颗粒暴露在某些环境中,如强酸或氧化剂的存在时,这些颗粒能够分解,以便铁螯合试剂可以从它们的环境中螯合铁或其他金属。还提供了制备这些新组合物的方法。这些组合物或包含本技术的纳米凝胶的组合物可用于治疗金属过载症状,例如由于慢性输血导致的铁过载。
