PROBLEM TO BE SOLVED: To provide an insulinotropic peptide derivative which is high blood stability and insulinotropic activity.SOLUTION: Insulinotropic peptide derivative is obtained by substituting 4-imidazoacetyl for an N-terminal histidine residue of native insulinotropic peptide. The native insulinotropic peptide is selected from exendin-4, exendin-3 and derivative thereof. The insulinotropic peptide derivative exhibits therapeutic effect, which are not observed in native and other insulinotropic peptide analog. The insulinotropic peptide derivative and the pharmaceutical composition comprising the same can be effectively provided for the treatment of diabetes.

PROBLEM TO BE SOLVED: To provide an N-terminal amino acid-modified insulinotropic peptide having a high activity, and to provide a pharmaceutical composition comprising the same.SOLUTION: In the insulinotropic peptide derivative, N-terminal histidine residue of a native insulinotropic peptide is substituted by N-dimethyl-histidyl. The insulinotropic peptide derivatives 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 can be used for the effective treatment of diabetes.

PROBLEM TO BE SOLVED: To provide a pharmaceutical composition containing as an active ingredient a novel compound having epidermal growth factor receptor (EGFR) tyrosine kinase activity inhibitory action and having effect of treating and preventing cancers, tumors, inflammatory diseases, autoimmune diseases, or immunologically mediated diseases.SOLUTION: The present invention provides a fused pyrimidine derivative represented by the chemical formula (I) or a pharmaceutically acceptable salt thereof. [W is O or S; X is O, S, SO or the like; Y, A and B are each independently H, halogen, or di(Calkyl)aminomethyl; and Z is a substituted aryl, a substituted heteroaryl or the like.]

PROBLEM TO BE SOLVED: To provide a method for the mass production of an immunoglobulin Fc region, free of initial methionine residues.SOLUTION: Disclosed is a method for the mass production of a monomeric or dimeric immunoglobulin Fc region, free of initial methionine residues, using a recombinant expression vector comprising a nucleotide sequence coding for a recombinant immunoglobulin Fc region comprising an immunoglobulin hinge Fc region linked at the N-terminus thereof to an immunoglobulin Fc region via a peptide bond. Thus the monomeric or dimeric immunoglobulin Fc region, free of the initial methionine residues, is mass-produced.

PROBLEM TO BE SOLVED: To provide an N-terminal amino acid-modified insulinotropic peptide having a high activity, and to provide a pharmaceutical composition comprising the same.SOLUTION: An insulinotropic peptide derivative, wherein N-terminal histidine residue of native insulinotropic peptide is replaced with beta-hydroxy imidazopropionyl. The insulinotropic peptide derivatives exhibit therapeutic effects, which are not observed in native and other insulinotropic peptide analogs.
