摘要:
The present invention relates to insulin derivatives in which a lipophilic group having from 12 to 40 carbon atoms is attached to the &agr;-amino group of the N-terminal amino acid in the B-chain or to the carboxy group of the C-terminal amino acid in the B-chain have a protracted profile of action.

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:
Disclosed is a method of preparing zinc free rapid acting insulin analogue. In one embodiment insulin crystals are prepared by providing a solution of an analogue having a pH between 7 and 9.5. The solution is mixed with a salt of an alkali metal or salt and formed crystals are recovered.
摘要:
Novel insulin precursors and insulin precursor analogs comprising a connecting peptide (mini C-peptide) of preferably up to 15 amino acid residues and comprising at least one Gly are provided. The precursors can be converted into human insulin or a human insulin analog. The precursors will typically have a distance between B27 (atom CG2) and A1 (atom CA) of less than 5 Å.
摘要:
Disclosed is a method for producing seeding microcrystals for the production of human insulin, the microcrystals being free of non-human pancreatic insulin, the method comprising providing an unseeded suspension of human insulin, the suspension being free of non-human pancreatic insulin, and homogenizing the insulin suspension under pressure to result in human insulin microcrystals suitable for use as seeding microcrystals for the production of zinc insulin products. The method of homogenization under pressure may also be used for the production of seeding mnicrocrystals for other peptides and proteins, in particular pharmaceutical peptides or proteins such as insulin, GLP-1, glucagon and growth hormones.
摘要:
Novel insulin precursors and insulin precursor analogs having a mini C-peptide comprising at least one aromatic amino acid residue have an increased folding stability. The novel insulin precursors and insulin precursor analogs can be expressed in yeast in high yields and are preferably not more 15 amino acid residues in length. Also provided are polynucleotide sequences encoding the claimed precursors or precursor analogs, and vectors and cell lines containing such polynucleotide sequences.
摘要:
The present invention is directed toward peptide analogues of insulin B chain that are generally derived from peptides comprising residues 9 to 23 of the native B chain sequence. The analogues are altered from the native sequence at position 12, 13, 15 and/or 16, and may be additionally be altered at position 19 and/or other positions. Pharmaceutical compositions containing these peptide analogues arc provided. The peptide analogues are useful for treating and inhibiting the development of diabetes.
