Abstract
Described are polypeptide analogs of parathyroid hormone (PTH) that include at least two non-adjacent β-amino acid residues in place of a naturally occurring α-amino acid residues. Also described are pharmaceutical compositions useful for treating hypoparathyroidism that contain the analogs and methods of using the analogs to treat hypoparathyroidism.
Claims12
An isolated, unnatural peptide analog comprising:
- PTH, a parathyroid hormone receptor (PTHR-1, PTHR-2) agonist- or inverse agonist effective fragment of PTH, a parathyroid hormone related protein (PTHrP), a PTHR-1 or PTHR-2 agonist-, or inverse agonist-effective fragment of PTHrP, M-PTH, a PTHR-1 or PTHR-2 agonist- or inverse agonist-effective fragment of M-PTH, BA058, or a PTHR-1 or PTHR-2 agonist-, or inverse agonist-effective fragment of BA058, in which at least five non-adjacent α-amino acid residues are replaced with β-amino acid residues;
- and
- salts thereof.
A pharmaceutical composition for treating hypoparathyroidism, the composition comprising a parathyroid hormone receptor agonist-effective amount of PTH, a parathyroid hormone receptor (PTHR-1, PTHR-2) agonist-effective fragment of PTH, a parathyroid hormone related protein (PTHrP), a PTHR-1 or PTHR-2 agonist-effective fragment of PTHrP, M-PTH, a PTHR-1 or PTHR-2 agonist-effective fragment of M-PTH, BA058, or a PTHR-1 or PTHR-2 agonist-effective fragment of BA058, in which at least five non-adjacent α-amino acid residues are replaced with β-amino acid residues, in combination with a pharmaceutically suitable carrier.
