Macromolecule compositions using hydroxamate or oxime groups covalently coupled with biological cells and macromolecules, and in particular, with albumin and acellular hemoglobin, are provided. In particular embodiments, hydroxamate or oxime groups are covalently coupled with acellular hemoglobin and compounded to provide several formulations for a red cell substitute that will possess oxidant toxin-scavenging properties. The invention also provides a method of preventing and treating pathologies related to the actions of oxidant toxins or oxidative stress in a mammal. The method comprises administering to a mammal a therapeutically effective amount of a macromolecule composition comprising a macromolecule coupled with at least one hydroxamate or oxime group.
提供了使用羟肟酸酯或肟基团与生物细胞和大分子,特别是与白蛋白和无细胞血红蛋白共价偶联的大分子组合物。在特定的实施方案中,羟肟酸酯或肟基团与无细胞血红蛋白共价偶联并复配,以提供多种具有氧化剂毒素清除特性的红细胞替代物配方。本发明还提供了一种预防和治疗与哺乳动物体内氧化剂毒素或氧化应激作用有关的病症的方法。该方法包括向哺乳动物施用治疗有效量的大分子组合物,该组合物包含与至少一个羟酰胺基团或肟基团偶联的大分子。
