  • Patent number: 8454934
    Abstract: A chelation structure and method of forming and using the chelation structure. The chelation structure has a backbone that includes a linear sequence of monomeric backbone units, at least one polymer side chain, and at least one chelator side chain. The side chains are each covalently coupled to the backbone at one of the monomeric backbone units by a bond that is independently biodegradable or non-biodegradable. The chelation structure is synthesized by Radical Addition Fragmentation Transfer (RAFT), Atom Transfer Radical Polymerization (ATRP), or Free Radical Polymerization (FRP). The chelation structure, individually or in combination with a shuttle chelator, may be introduced into a mammal to bind an amount of a substance in a mammal, the substance being at least one of a metal and heme. The chelation structure has a log stability constant exceeding that of the shuttle chelator for binding the substance within cells of the mammal.

  • Publication number: 20080213369
    Abstract: A synthetic platelet substitute that interacts with platelets and the (sub)endothelium, comprising: (a) a carrier molecule comprising lipidic particles with a cross-linked surface mesh, the lipidic particles comprising: an inner lipidic particle of pharmaceutically acceptable particle-forming lipids; hydrophilic polymer chains linked to the surface of the lipidic particle, the hydrophilic polymer chains comprising a crosslinkable end group at free ends thereof; and cross-linker groups linking the end groups of the hydrophilic polymer chains to form the cross-linked surface mesh; and (b) at least one receptor molecule attached to the surface of the carrier molecule. The receptor molecule can be a peptide moiety specific for ligands involved in platelet function.
