1. Design and Synthesis of AT2 Receptor Selective Angiotensin II Analogues Encompassing β- and γ-Turn Mimetics
Sammanfattning : Important information on the bioactive conformation of biologically active peptides may be obtained by studies of rigid peptides or well-defined secondary structure mimetics incorporated into pseudopeptides. The structural requirements for the interaction of angiotensin II (Ang II, Asp-Arg-Val-Tyr-Ile-His-Pro-Phe) with its AT1 and AT2 receptors were the subject of this study. LÄS MER
2. Design and Synthesis of Novel AT2 Receptor Ligands : From Peptides to Drug-Like Molecules
Sammanfattning : Many peptide receptors are of pharmaceutical interest and there is thus a need for new ligands for such receptors. Unfortunately, peptides are not suitable as orally administrated drugs since they are associated with poor absorption, rapid metabolism and low sub-receptor selectivity. LÄS MER
3. Design and Synthesis of Angiotensin IV Peptidomimetics Targeting the Insulin-Regulated Aminopeptidase (IRAP)
Sammanfattning : Peptidomimetics derived from the bioactive hexapeptide angiotensin IV (Ang IV, Val1-Tyr2-Ile3-His4-Pro5-Phe6) have been designed and synthesized. These peptidomimetics are aimed at inhibiting the insulin-regulated amino peptidase (IRAP), also known as the AT4 receptor. LÄS MER
4. Design and synthesis of -turn peptidomimetics : Applications to angiotensin II
Sammanfattning : This study addresses the issue of how to convert peptides into drug-like non-peptides while retaining the biological activity at peptide receptors. Angiotensin II (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe, Ang II) was used as a model peptide. Small bioactive peptides are in most cases conformationally flexible molecules. LÄS MER
