Definitions

  • the present invention relates to peptide analogs of the islet amyloid polypeptide (IAPP), methods for finding IAPP or its aggregates, pharmaceutical compositions for the prophylaxis and therapy of protein aggregation diseases, in particular diabetes and Alzheimer's disease and diagnostic Zu ⁇ compositions for the detection of Proteinaggregationskrankhei ⁇ th, in particular diabetes and Alzheimer's disease as well as uses of said peptide analogues for purposes of diagnosis and therapy of diseases or for basic research.
  • IAPP islet amyloid polypeptide
  • Diabetes is a disease for which there are currently no satisfactory therapeutic approaches. Usually, a distinction is made between Type I and Type II diabetes. 90% of diabetics suffer from type II diabetes or adult-onset diabetes. Today, there are more than 150 million Type II diabetics worldwide. Diabetes is caused by the lack of insulin or by the disturbed course of insulin-dependent biological processes. Since, on the one hand, the central role of insulin in the carbohydrate metabolism can not be replaced by other molecules, and on the other hand, the action of insulin alone does not eliminate the pathological consequences of the disease in the case of type I diabetes or the disease itself in the case of type II diabetes can, new therapeutic approaches are necessary.
  • Such concepts should on the one hand support the secretion, uptake and unfolding of the biological function of the insulin molecule and on the other hand against unwanted side effects of insulin such as weight gain or hypoglycemia. to protect against kaemia.
  • New molecules, which contribute in particular together with insulin for the regulation of carbohydrate metabolism, are thus of great biomedical interest.
  • IAPP islet amyloid polypeptide
  • amylin is a peptide hormone consisting of 37 amino acids, which is synthesized in the pancreatic ⁇ -cells and, together with insulin and glucagon, is involved in the regulation of sugar metabolism. IAPP is an antagonist of insulin.
  • amyloid plaques are found in the pancreas of more than 95% of the type II diabetics. Amyloid plaques are deposits consisting of insoluble aggregates of the polypeptide IAPP.
  • Parkinson's, prion diseases or Huntington's disease diabetes can therefore also be regarded as protein aggregation disease (Ross and Poirier, Nature Medicine, July 2004, Vol.
  • IAPP amyloid plaques, soluble oligomers and multirnere forms of the lAPP molecule are cytotoxic. It is assumed that the damage to the ⁇ -cells caused by lAPP amyloid formation makes a considerable contribution to the cascade of the pathogenesis of type II diabetes. Therefore, the development of therapeutically effective inhibitors of the lAPP amyloid formation process is of great biomedical interest.
  • the IAPP molecule in its biological function as an insulin antagonist and as a regulator of postprandial hypoglycaemia associated with insulin secretion or administration, is per se an important polypeptide hormone which has potential therapeutic applications in the treatment of type I (for example in combination with insulin) and Type II could have diabetes.
  • the medical application of IAPP is considerably limited due to its poor solubility and its strong aggregation tendency.
  • the soluble lAPP analog pramlintide is known.
  • Pramlintide (Sym5lin®) was produced by the replacement of 3 amino acid residues at positions 25, 28, and 29 in the sequence of the human IAPP molecule by proline. These proline substituents occur in the rat ILPP sequence, which itself has no aggregation tendency. Structurally, the diminished aggregation tendency of pro-olin-containing sequences can be explained by the fact that proline residues are incapable of accepting ⁇ -sheet conformations (prolines are ⁇ -sheet "breaking" residues). In fact, the lAPP analog pramlintide has a greatly reduced tendency to aggregate and thus a better solubility profile than human IAPP.
  • the present invention is therefore based on the technical problem of providing means and methods by means of which improved prophylaxis, therapy and diagnosis of protein aggregation diseases, in particular of diabetes and / or Alzheimer's disease, are made possible.

  • LAPP amyloid aggregates are cytotoxic to pancreatic ⁇ cells and to a number of other cells. It is believed that the cytotoxic effect of IAPP and other amyloid polypeptides is associated with their aggregation to amyloid. From this follows the assumption that, since the analogs are not amyloidogenic, they should not be cytotoxic either. To investigate this assumption, the MTT cytotoxicity test was used, which is based on the reduction of the dye 3- [4,5-dimethylthiazol-2-yl] -2,5-diphenyltetrazolium bromide (MTT) by "healthy" cells with intact redox potential (Shearman et al., J.

Thereafter, apoptosis was by means of a commercial Apoptosis ELISAs (Cell Death Detection Kit from Roche) quantified.
