Outline of Final Research Achievements

In recent years, it has become clear that unlimited ingestion of iron ions enhances the risk of developing carcinogenesis and various serious diseases. In patients with myeloid dysfunction syndrome, it has been desired to develop a biologically safe removal system, because the blood contains excess iron ions due to long-term transfusion.
In this study, molecular design and preparation of novel chelating materials using polyethylene glycol with high biocompatibility, and verification of iron ion removal effect were carried out. As a result, phosphate-terminated polyethylene glycols with 4-branches and 8-branches structures effectively interact with iron ions and iron ions were effectively removed through dialysis membranes.
