Nucleic acid molecules encoding the albumin fusion proteins of the invention are also encompassed by the invention, as are vectors containing these nucleic acids, host cells transformed with these nucleic acids vectors, and methods of making the albumin fusion proteins of the invention and using these nucleic acids, vectors, and/or host cells. Additionally the present invention encompasses pharmaceutical compositions comprising albumin fusion proteins and methods of treating, preventing, or ameliorating diseases, disorders or conditions using albumin fusion proteins of the invention.
摘要:
The invention relates to truncated TIP39 polypeptides and chimeric PTHrP/TIP polypeptides. The polypeptides are used as agonists or antagonists of PTH receptors in various medical conditions.
摘要:
This invention describes analogues of human parathyroid hormone which have increased activities in bone restoration, and increased bioavailabilities. The peptides described are derivatives of hPTH-(1-31) which are cyclized for example, by formation of Lactams between either Glu and Lys or Lys and Asp . In addition, the natural Lys may be substituted by either a Leu or other hydrophobic residues, such as Ile, norleucine, Met, Val, Ala, Trp, or Phe. Typically, these analogues have enhanced abilities to stimulate adenylyl cyclase in rat osteosarcoma cells, and show increased activities in bone restoration, using the ovariectomized rat model. The analogues also show enhanced activities and bioavailabilities, as demonstrated by their hypotensive effects in the rat. An assay which correlates hypotensive activity with osteogenic activity is also described.
摘要:
Novel parathyroid hormone peptide (PTH) and parathyroid hormone related peptide (PTHrP) or derivatives thereof which are biologically active are disclosed, as are pharmaceutical compositions containing said peptides, and synthetic and recombinant methods for producing said peptides. Also disclosed are methods for treating mammalian conditions characterized by decreases in bone mass using therapeutically effective pharmaceutical compositions containing said peptides. 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.
摘要:
This invention is directed to a process for the solid phase, fragment-based synthesis of resin-bound cyclic peptide analogs of parathyroid hormones and analogs of parathyroid hormone-related proteins, which analogs contain at least one bridge between the side chains of two non-adjacent amino acid residues, and to peptide fragments useful therefor.
摘要:
