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)2Laaand 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. |
