  • Long acting formulation of biopharmaceutical
    Patent number: 8247493
    Abstract: The invention relates to a long-acting formulation of biopharmaceutical, more specifically an aptamer therapeutics. A branched PEGylated aptamer or a hyaluronic acid (HA) derivative of which degradation in vivo is regulated is linked by the bioconjugation with biopharmaceutical to produce the long-action formulation.
    Type: Grant
    Filed: April 13, 2009
    Date of Patent: August 21, 2012
    Assignees: Postech Academy-Industry Foundation, Posco
    Inventors: Sei-Kwang Hahn, Hyun-Gu Kang, Sung-Ho Ryu, Jung-Kyu Park, Eun-Ju Oh
  • Bone filling complex and method for fabricating the same
    Patent number: 8183229
    Abstract: Provided is a bone filling complex and method of preparing the same. The bone filling complex includes a matrix including a hydrogel-type hyaluronic acid derivative; and a bone derivative filling the matrix For example, the bone filling complex can be used to regenerate an injured alveolar bone.

  • BONE FILLING COMPLEX AND METHOD FOR FABRICATING THE SAME
    Publication number: 20100249059
    Abstract: Provided is a bone filling complex and a method of preparing the same. The bone filling complex includes a matrix including a hydrogel-type hyaluronic acid derivative; and a bone derivative filling the matrix, and thus adhesion can be prevented and excellent bone generation property can be obtained. For example, the bone filling complex can be used to an injured portion of alveolar bone to derive an regeneration of the alveolar bone.

  • LONG ACTING HYALURONIC ACID - PEPTIDE CONJUGATE
    Publication number: 20100210509
    Abstract: The invention relates to a novel bioconjugation protocol for peptide suitable for in vivo applications. Bioconjugation of the peptide to HA derivative increases its half life in circulation contributing for a high efficacy. More over, conjugate of HA derivative and peptide which is treated with hyaluronidase shows increased bioactivity. And also, in contrast to PEGylation, HA derivative can be conjugated with many numbers of peptide molecules per single HA derivative chain, which enables multiple action of peptide drugs.
