  • Patent number: 10421843
    Abstract: Amino acid-based poly(ester amide) (PEA) macromers (e.g., functional PEA macromers) and methods for preparing amino acid-based poly(ester amide) (PEA) macromers. The functional PEA macromers can comprise functional groups such as hydroxyl, amine, sulfonic acids, carboxyl, thiol and acryloyl at the two terminuses of the PEA macromers. The content of the terminal functional groups on the macromers can be precisely controlled by adjusting the molar ratio of reactive monomers. The resulting versatility of these new functional PEA macromers can be used to fabricate a wide range of PEAs and PEA hybrid derivatives with very different chemical, physical, mechanical, thermal and biological properties. The functional PEA macromers can also be polycondensed into forming block PEA polymers.

  • Patent number: 8858998
    Abstract: Cationic poly(ester amide) (PEA)-based hydrogels are provided. The hydrogels are fabricated from unsaturated L-arginine base poly(ester-amide) (UArg-PEA) precursors, pluronicDA precursors, or a combination of UArg-PEA and pluronicDA precursors at predetermined precursor composition ratios. PluronicDA/UArg-PEA hybrid hydrogels and pure pluronicDA based hydrogels are thermoresponsive and biodegradable, while pure UArg-PEA base hydrogels are biodegradable but not thermoresponsive. UArg-PEA based, pluronicDA based and hybrid hydrogels can be synthesized from unsaturated arginine-based PEA salts and/or unsaturated pluronic acid polymers. Unsaturated pluronic acid polymers can be synthesized by reacting pluronic acid with acryloylchloride to provided functional vinyl groups at the two chain ends of pluronic acid. The hydrogels can be used to carry and/or release molecules or compounds such as bioactive compounds, and can function as biologic carriers for a variety of biomedical applications.
