摘要:
The invention relates to a precursor of human insulin or of an insulin analog of the formula I: Fus-B(1-30)-RDVP-Yn-A(1-21) (I); wherein Fus is an optionally present fusion portion; B(1-30) is a B chain of human insulin, Y is an amino acid chain which terminates with a basic amino acid at the C terminus; n is from 2 to 50 and indicates the length of the amino acid chain Y; and A(1-21) is an A chain of human insulin, and the A chain and/or the B chain can be modified by amino acid substitution, deletions and/or additions. The present invention also provides DNA coding for the above precursors, preparation and use of the instant precursors and DNA, and a process for preparing human insulin or an insulin analog.
摘要:
Insulin derivatives with increased zinc binding where Z is a histidine residue or a peptide having 2 to 35 genetically encodable amino acid residues, having 1 to 5 histidine residues, are suitable for the production of pharmaceutical preparations for the treatment of diabetes. Insulins of the formula I form complexes with zinc++, comprising an insulin hexamer and approximately 5 to 9 mol of zinc++ per hexamer.
摘要:
The invention relates to novel insulin analogs having a basal time-action profile, which are characterized by the addition and/or substitution of negatively and positively charged amino acid residues and by an amidation of the C-terminal carboxy group of the B chain and histidine in position 8 of the insulin A chain. The invention also relates to the production and use thereof.
摘要:
The invention relates to a method for producing C-terminal amidated dibasic or polybasic peptides, consisting in reacting two peptides in the presence of trypsin biologically active enzymes and, if necessary, in purifying the thus obtainable compounds of formula (I) by means of protein chemistry.

摘要:
The present invention relates to insulin derivatives which in comparison to human insulin, have an accelerated onset of action, to a process for their preparation and to their use, in particular in pharmaceutical preparations for the treatment of diabetes mellitus. In particular, the present invention relates to insulin derivatives or physiologically tolerable salts thereof in which asparagine (Asn) in position B3 of the B chain is replaced by a naturally occurring basic amino acid residue and at least one amino acid residue in the positions B27, B28 or B29 of the B chain is replaced by another naturally occurring amino acid residue, it optionally being possible for asparagine (Asn) in position 21 of the A chain to be replaced by Asp, Gly, Ser, Thr or Ala and for phenylalanine (Phe) in position B1 of the B chain and the amino acid residue in position B30 of the B chain to be absent.
摘要:
The invention relates to a novel process for using the yeast ADH II promoter system for the production of heterologous proteins in high yields, for example for preparing hirudins, miniproinsulins, leptins or derivatives thereof.
摘要:
Expression of a gene coding for human granulocyte macrophage colony-stimulating factor (CSF) in bacteria results in CSF proteins which are biologically active. Modification of the natural or of a synthetic gene structure results in biologically active derivatives with a modified amino acid sequence.
摘要:
The invention relates to insulin glargine which is modified by amidation, especially Gly(A21), Arg(B31), Arg amide (B32) human insulin (insulin glargine amide).
摘要:
