Treatment of hyperphosphatemia based on specific interactions between phosphorus and Zr(iv) active centers of nano-MOFs

Abstract

Hyperphosphatemia is closely associated with the occurrence of multiple organ dysfunctions in patients with end-stage renal disease (ESRD). The application of phosphorus binders as an effective clinical approach for such diseases still suffers from serious side effects. Therefore, development of new phosphorus binders for the treatment of hyperphosphatemia remains a great challenge. Herein, we describe a kind of zirconium (Zr(IV))-based nano-MOF that is well suited for specific adsorption and selective fluorescence sensing of phosphate, and is based on the particular interactions between Zr(IV) and phosphate. The reduced levels of phosphate were quantitatively monitored using the MOF-based fluorescence nanosensor. Notably, the MOFs exhibit a greater reduction in phosphorus levels than commercially available phosphorus binders, and comparable therapeutic effects in the treatment of hyperphosphatemia of a mice model. Hence, the MOF acts as a promising medication for hyperphosphatemia by directly adsorbing phosphorus in the blood, which offers new perspectives in future applications of MOFs.
