乳糖酸是用于在移植前保存器官的溶液的主要成分,它可以螯合三价铁。这通过其溶解铁的能力以及在其存在下铁的UV-VIS光谱中发生的变化来证明。相对于螯合到EDTA的铁(III),乳糖酸-铁(III)络合物较少能够参与芬顿反应,如通过从DMSO产生甲醛和对-N,N-二甲基亚硝基苯胺的漂白所测量的。柠檬酸盐和ATP也有类似的作用,这两种物质似乎也能够改善缺血/再灌注损伤。这些发现为乳糖酸作为器官净化剂的有效性提供了理论依据。
Lactobionic acid, a major constituent of a solution used to preserve organs prior to transplantation, can chelate ferric iron. This is evident by its ability to solubilize iron as well as changes that occur in the UV-VIS spectra of iron in its presence. Relative to iron (III) chelated to EDTA, the lactobionic acid-iron (III) complex is less able to participate in the Fenton reaction as measured by formaldehyde generation from DMSO and bleaching of p-N, N-dimethylnitrosoaniline. Similar effects are seen with citrate and ATP, two substances which also appear to be able to ameliorate ischemia/reperfusion injury. These findings present a rationale for the effectiveness of lactobionic acid as an organ preservant.
