  • Analogs of parathyroid hormone and parathyroid hormone related peptide: synthesis and use for the treatment of osteoporosis
    Patent number: 6051686
    Abstract: Synthetic polypeptide analogs of parathyroid hormone PTH, parathyroid hormone related peptide PTHrp, and of the physiologically active truncated homologs and analogs of PTH and PTHrp, in which amino acid residues (22-31) form an amphipathic .alpha.-helix, said residues (22-31) selected from hydrophilic amino acids (Haa) and lipophilic amino acids (Laa) ordered in the sequence:Haa(Laa Laa Haa Haa).sub.2 Laaand their pharmaceutically acceptable salts are useful for the prophylaxis and treatment of ostoporosis in mammals. Processes for the production of the polypeptides via solid phase and recombinant methods are provided.
    Type: Grant
    Filed: May 23, 1995
    Date of Patent: April 18, 2000
    Assignee: Syntex (U.S.A.) Inc.
