PTH derivatives having one or more amino acid substitutions that confer PTH-1/PTH-2 receptor agonist properties comprising a biologically active peptide at least 90% identical to a peptide consisting essentially of the formula: (a) X01 ValSerGluIleGlnLeuMetHisAsnLeuGlyLysHisLeuAs nSerMetGluArgValGluTrpLeuArgLysLysLeuGlnAspValHisAsnPhe (SEQ ID NO:1); (b) fragments thereof containing amino acids 1-29, 1-30, 1-31, 1-32, or 1-33; (c) pharmaceutically acceptable salts thereof; or (d) N- or C-derivatives thereof; wherein: X01 is desamino Ser, desamino Ala or desamino Gly, provided that said peptide is not desamino Ser1 hPTH(1-31)NH2 or desamino Ser1 hPTH(1-34)NH2. |
