  • Synthesis of cyclic peptides
    Patent number: 5990273
    Abstract: A process for preparing and purifying cyclic peptides having disulfide moieties in a two step processing operation including reverse phase chromatography which simplifies synthesis and reduces production costs, yet produces high, quality yield. The improved process is particularly useful for the preparation of vasopressin and oxytocin and their respective derivatives and analogs.
    Type: Grant
    Filed: November 10, 1997
    Date of Patent: November 23, 1999
    Assignee: Ferring B.V.
    Inventors: Lars Henrik Harald Andersson, Jan-Ake Skoldback
  • Synthesis of cyclic peptides
    Patent number: 5726287
    Abstract: A process for preparing and purifying cyclic peptides having disulfide moieties in a single processing operation which simplifies synthesis and reduces production costs, yet produces high, quality yield. Higher yields are obtained by isolating the desired cyclic compound through direct ion exchange chromatography as an integral part of the single process. The improved process is particularly useful for the preparation of vasopressin and oxytocin and their respective derivatives and analogs.
