Abstract:
Disclosed is a liquid formulation in which a long-acting INFα conjugate that has improved in vivo duration and stability can be stored stably for a long period of time. It comprises a stabilizer comprising a buffer, a sugar alcohol, a non-ionic surfactant and an isotonic agent. Being free of human serum albumin and other potential factors harmful to the body, the liquid formulation is free of concerns about viral infections and guarantees excellent storage stability to long-acting INFα conjugates.
Abstract:
The present invention relates to a method for outputting a convergence index, and more particularly, to a method for outputting a convergence index by utilizing patent information. According to the method for outputting the convergence index of the present invention, the convergence index can be outputted by using time information related to a patent which is included in a patent group, a patent classification, and an industrial classification that corresponds to the patent classification. The method for outputting the convergence index of the present invention systematically outputs the convergence index by using patent data, which is an objective data, thereby outputting the convergence index which is objective and appropriate.
Abstract:
Disclosed is a liquid formulation which allows long-acting G-CSF conjugates, that have improved in vivo duration and stability, to be stable when stored for a long period of time. It comprises a stabilizer composition characterized by buffer and mannitol. Being free of human serum albumin and other potential factors harmful to the body, the liquid formulation is free of concerns about viral infections and guarantees excellent storage stability to long-acting G-CSF conjugates.
Abstract:
Disclosed are a protein conjugate with improved in vivo duration and stability and the use thereof. The protein conjugate includes a physiologically active polypeptide, a non-peptide polymer and an immunoglobulin Fc fragment. Since the three components are covalently linked, the protein conjugate has extended in vivo duration and enhanced stability for the physiologically active polypeptide. The protein conjugate maintains the in vivo activity at relatively high levels and remarkably increases the serum half-life for the physiologically active polypeptide, with less risk of inducing undesirable immune responses. Thus, the protein conjugate is useful for developing long-acting formulations of various polypeptide drugs.
Abstract:
A modified human granulocyte-colony stimulating factor (hG-CSF) is produced by culturing a microorganism transformed with an expression vector comprising a gene encoding a modified hG-CSF to produce and secrete the modified hG-CSF to periplasm, said modified hG-CSF being obtained by replacing at least one of the 1st, 2nd, 3rd and 17th amino acids of wild-type hG-CSF (SEQ ID NO: 2) with other amino acid.

Abstract:
Disclosed in this invention are an expression vector for the secretive production of human interferon alpha (hIFNα) comprising a polynucleotide encoding a modified E. coli thermostable enterotoxin II signal sequence and a polynucleotide encoding hIFNα ligated to the 3′-end thereof; a microorganism transformed with the expression vector; and a process for secretively producing human interferon by culturing the microorganism, the process being capable of secreting a soluble form of active hIFNα, which does not contain an additional methionine residue at its N-terminal, into the periplasm of an E. coli cell.
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.
Abstract:
The present invention relates to an N-terminal amino acid-modified insulinotropic peptide having a high activity, and to a pharmaceutical composition comprising the same. The insulinotropic peptide derivatives according to the present invention exhibit therapeutic effects, which are not observed in native and other insulinotropic peptide analogs. Therefore, the insulinotropic peptide derivatives and the pharmaceutical composition comprising the same according to the present invention can be effectively provided for the treatment of the diseases.
