Patents Assigned to CHELATION PARTNERS INCORPORATED
  • Polymeric metal chelating compositions and methods of preparing same for controlling growth and activities of living cells and organisms
    Patent number: 11059785
    Abstract: Disclosed are chelating co-polymer compositions that are soluble in aqueous media and chelate essential metals, methods of preparation and uses thereof. The chelating compositions are comprised of two or more different monomers, at least one of which possesses metal binding or metal chelating activity. The chelating compositions are synthesized by reversible addition-fragmentation transfer (RAFT) polymerization with the aid of a suitable RAFT-mediating agent. Also described are chelating compositions that comprise hydroxypyridinone chelating groups. The ability of the chelating compositions to bind metals affects the activity of a living cells and organisms, which require the metals for cellular functions.

  • METAL CHELATING COMPOSITIONS AND METHODS FOR CONTROLLING THE GROWTH OR ACTIVITIES OF A LIVING CELL OR ORGANISM
    Publication number: 20200297848
    Abstract: The present invention provides for metal chelating compositions which are soluble in aqueous media. The present invention also provides chelating compositions that possess acceptable iron sequestering strengths and are able to present a physical form that potentially inhibits (e.g. does not permit easy) access of iron sequestered by the compositions to the cells being targeted. Compositions comprising chelating aspects affixed to or incorporated into suitable carrier materials such that the resulting metal chelating composition is soluble in aqueous media are also provided. Disclosed herein are chelating compositions, for chelating one or more essential metals.
