20090264365 | CONFORMATIONALLY CONSTRAINED PARATHYROID HORMONE (PTH) ANALOGS - The present invention relates to conformationally constrained parathyroid hormone (PTH) analogs, and methods of preparing and using the PTH analogs. The invention provides novel PTH polypeptide derivatives containing amino acid substitutions at selected positions in the polypeptides. The invention provides derivatives of PTH(1-34), PTH(1-21), PTH(1-20), PTH(1-19), PTH(1-18), PTH(1-17), PTH(1-16), PTH(1-15), PTH(1-14), PTH(1-13), PTH(1-12), PTH(1-11), and PTH(1-10) polypeptides, wherein at least one residue in each polypeptide is a helix, preferably an α-helix, stabilizing residue. The invention also provides methods of making such peptides. Further, the invention encompasses compositions and methods for use in limiting undesired bone loss in a vertebrate at risk of such bone loss, in treating conditions that are characterized by undesired bone loss or by the need for bone growth, e.g., in treating fractures or cartilage disorders and for raising cAMP levels in cells where deemed necessary. | 10-22-2009 |
20100081612 | POLYPEPTIDE DERIVATIVES OF PARATHYROID HORMONE (PTH) - The present invention is related to novel parathyroid hormone polypeptide derivatives, and to pharmaceutical composition containing the polypeptides, as well as synthetic and recombinant methods for producing the polypeptides. Also disclosed are methods for treating mammalian conditions characterized by decreases in bone mass using therapeutically effective pharmaceutical compositions containing the polypeptides of the present invention. The present invention further provides diagnostic and therapeutic methods using the polypeptide derivatives. | 04-01-2010 |
20110009328 | Polypeptide Derivatives of Parathyroid Hormone (PTH) - Novel parathyroid hormone (PTH) polypeptide derivatives are disclosed, as are pharmaceutical compositions containing said polypeptides, and synthetic and recombinant methods for producing said polypeptides. Also disclosed are methods for treating mammalian conditions characterized by decreases in bone mass using therapeutically effective pharmaceutical compositions containing said polypeptides. Also disclosed are methods for screening candidate compounds of the invention for antagonistic or agonistic effects on parathyroid hormone receptor action. Also disclosed are diagnostic and therapeutic methods of said compounds. | 01-13-2011 |
20110172153 | SCREENING METHODS USING G-PROTEIN COUPLED RECEPTORS AND RELATED COMPOSITIONS - The present invention provides screening methods for GPCRs based on the discovery that the affinity of a receptor agonist for a GPCR (such as the parathyroid hormone receptor) when not bound to a G-protein is correlated with the length of time over which the agonist is effective, independently of its pharmacokinetic properties. The invention also provides PTH- and PTHrP-derived polypeptides. | 07-14-2011 |
20130116180 | PARATHYROID HORMONE ANALOGS AND USES THEREOF - Disclosed are two PTH analog ligands, SP-PTH-AAK and Aib-SP-PTH-AAK, that have long-acting activity at the PTH receptor, as demonstrated both in vitro and in vivo. These polypeptides are thus particularly useful in the treatment of diseases, such as hypoparathyroidism, in which long-acting activity is desired. The method of making the analog polypeptides is also disclosed. | 05-09-2013 |
20140086842 | SCREENING METHODS USING G-PROTEIN COUPLED RECEPTORS AND RELATED COMPOSITIONS - The present invention provides screening methods for GPCRs based on the discovery that the affinity of a receptor agonist for a GPCR (such as the parathyroid hormone receptor) when not bound to a G-protein is correlated with the length of time over which the agonist is effective, independently of its pharmacokinetic properties. The invention also provides PTH- and PTHrP-derived polypeptides. | 03-27-2014 |
