  • Patent number: 8604127
    Abstract: The present invention relates to a conjugate of a protein or peptide with a polyethylene glycol derivative having catechol, wherein the protein or peptide is mono-PEGylated at the N-terminal with the polyethylene glycol derivative, and to a preparation method thereof. According to the invention, the catechol-PEG derivative can be site-specifically conjugated with the N-terminal amine group of a protein or peptide, so that a homogeneous polyethylene glycol-protein or -peptide conjugate can be obtained in high yield. Unlike a prior art conjugate, the conjugate obtained according to the invention allows the decrease in the activity of the protein to be minimized without chemically modifying the protein, and thus the conjugate has an excellent pharmacological effect. Also, because the conjugate is homogeneous, the process for preparing the conjugate can be simplified. Moreover, the conjugate has uniform biological efficacy in vivo and shows strong resistance to hydrolysis and thus a long in vivo duration time.

  • Publication number: 20130028918
    Abstract: The present invention relates to an insulin conjugate having improved in vivo duration and stability, which is prepared by covalently linking insulin with an immunoglobulin Fc region via a non-peptidyl polymer, a long-acting formulation comprising the same, and a preparation method thereof. The insulin conjugate of the present invention maintains in vivo activity of the peptide at a relatively high level and remarkably increases the serum half-life thereof, thereby greatly improving drug compliance upon insulin treatment.
