摘要:
The present invention relates to the use of peptide analogues as inhibitors of their respective naturally occurring peptides. The structure of the peptide hormone analogues is exemplified by human humoral hypercalcemic factor (hHCF), wherein Lys.sup.13 or Lys.sup.11 is modified on the epsilon-amino group by biotin so as to produce HCF analogues which can inhibit the action of HCF.
摘要:
The present invention relates to the use of peptide hormone analogues as inhibitors of their respective naturally occurring peptide hormone. The structure of the peptide hormone analogues is exemplified by parathyroid hormone (PTH), wherein Lys.sup.13 is substituted to increase the biological activity of the PTH analogues. Thus, there are disclosed peptides having the formulae:PTH(7-34)NH.sub.2 ;[Tyr.sup.34 ]PTH(7-34)NH.sub.2 ;[D-Trp.sup.12, Tyr.sup.34 ]PTH(7-34)NH.sub.2 ;[Nle.sup.8,18, D-Trp.sup.12, Tyr.sup.34 ]PTH(7-34)NH.sub.2 ;[Nle.sup.8,18, Tyr.sup.34 ]PTH(7-34)NH.sub.2 ;desamino[Nle.sup.8,18, D-Trp.sup.12, Tyr.sup.34 ]PTH(7-34)NH.sub.2 ; and,desamino[Nle.sup.8,18, D-Trp.sup.12, Tyr.sup.34 ]PTH(8-34)NH.sub.2wherein Lys.sup.13 is modified in the epsilon-amino acid group by N,N-diisobutyl or 3-phenylpropanoyl.

摘要:
The present invention relates to the use of peptide hormone analogues as inhibitors of their respective naturally occurring peptide hormone and methods of synthesis of such analogues. The structure of the peptide hormone analogues is exemplified by parathyroid hormone wherein Trp.sup.23 is substituted by L-Phe or other hydrophobic amino acids such as Leu, Nle, Val, Tyr, beta-napthylalanine and alpha-napthylalanine.
摘要:
The present invention relates to the use of peptide analogues as inhibitors of their respective naturally occurring peptides. The structure of the peptide analogues is exemplified by an internal region of the N-terminus of humoral hypercalcemic factor hHCF, and truncations thereof: hHCF(14-34)NH.sub.2, hHCF(13-34)NH.sub.2, hHCF(12-34)NH.sub.2, hHCF(11-23)NH.sub.2, hHCF(10-34)NH.sub.2, hHCF(9-34)NH.sub.2, hHCF(8-34)NH.sub.2 and various amino acid substitutions.
摘要:
Cyclic analogs of PTH and PTHrP wherein a disulfide or amide bond links the side chains of residues A.sub.13 and A.sub.17, A.sub.26 and A.sub.30, or A.sub.13 and A.sub.17 and A.sub.26 and A.sub.30.
摘要:
Novel parathyroid hormone analogs and parathyroid hormones-related protein analogs are described. Further, methods of using these analogs to treat osteoporosis, promote the formation of bone, and inhibit bone loss are described.
摘要:
This invention relates to a series of PTH and PTHrP analogues that selectively bind to PTH2 receptors and as such may be useful in treating abnormal CNS functions; abnormal pancreatic functions; divergence from normal mineral metabolism and homeostasis; male infertility; regulation of abnormal blood pressure; and hypothalmic disease.
摘要:
The present invention relates to the use of peptide hormone analogues as inhibitors of their respective naturally occurring peptide hormone. The structure of the peptide hormone analogues is exemplified by parathyroid hormone wherein Phe.sup.7 is substituted by NMePhe, D-Phe, desamino Phe, or Met.sup.8 is substituted by NMeMet.
摘要:
A method of promoting bone formation in a human patient, which includes the step of administering continuously to the patient parathyroid hormone or its agonist for a period of at least one month at a dosage between 10 and 400 units/24 hrs. Also disclosed are novel parathyroid hormone agonists.
