The iron(III) affinity constants for schizokinen and its imide derivative are reported for the first time. Surprisingly, schizokinen possesses a higher affinity for iron(III) than desferrioxamine B; log KFeIII (FeL), 36.2 and 30.6, respectively. This increase in value is associated with the substitution of one hydroxamate function by an α-hydroxycarboxylate grouping. By virtue of the similarity of
首次报道了对裂殖素及其酰亚胺衍生物的铁(III)亲和常数。令人惊讶的是,与去铁氧敏B相比,裂殖素对铁(III)的亲和力更高。log K Fe III(FeL)分别为36.2和30.6。值的这种增加与一个异羟肟酸酯官能团被α-羟基羧酸酯基团取代有关。由于铁载体-铁(III)配合物和铁载体-镓(III)配合物的相似性,裂殖素(革兰氏阳性铁载体)具有基于68 Ga PET成像的潜力。

The present application discloses a method of binding a metal ion in water. The method comprises contacting the water with a fraction of dissolved organic material (DOM) to form a complex between the DOM fraction and the metal ion; and optionally separating the complex from the water. The present application also discloses a use of DOM for binding a metal ion in water.
