摘要:
AbstractDie Verknüpfung zweier Tetrapeptide nach der Azid‐Methode liefert das Eledoisin‐(4–11)‐Octapeptid ·2 TFA (6). Nach Kondensation (Phosphorazo‐Methode) von Z‐ bzw. Boc‐Ile‐NHGly(Nα‐Boc)‐OH mit Leu‐Met‐NH2erlaubt die gleiche Synthese mit dem Nα‐ungeschützten Heterotetrapeptid10, aus dem Reaktionsgemisch das [5‐Asparagin, 9‐Hydrazino‐essigsäure]Eledoisin‐(4‐11)‐Octapeptid‐Acetat (11) zu isolieren.

The regioselective acylation of the nitrogens in hydrazino acetic acid has been studied to obtain the hydrazide and N-amino amide peptidomimetic groups Their conformational influence on the β-turn structure has also been considered.
The invention relates to novel heterocycles of formula (I) processes for their preparation and their use for preparing medicaments for the treatment or prophylaxis of disorders, especially of hyperproliferative disorders.
