Abstract: The present invention relates to novel antagonists to a B1-bradykinin (B1-BK) receptor which have a good affinity and selectivity therefor, some of which being at least partially resistant to enzymatic degradation. The synthesis of the B1 receptors is induced during inflammation. Symptoms associated with inflammation (elevated hydrostatic pressure and plasma leakage or extravasation) have been observed in diabetic animal models (streptozotocin-induced diabetes (STZ)) as well as in spontaneously hypertensive rats (SHR). The present inventors confirm the presence of B1-BK receptors in these two models. B1-BK antagonists abolished the vasocontraction induced by B1-BK in SHR and STZ, and reduced the glycemia of diabetic animals to normal levels.

Abstract: This invention describes analogues of human parathyroid hormone which have increased activities in bone restoration, and increased bioavailability. The peptides described are derivatives of hPTH-(1-31) which are cyclized for example, by formation of lactams between either Glu22 and Lys26 or Lys26 and Asp30. In addition, the natural Lys27 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.

Abstract: Certain analogues of human parathyroid hormone (hPTH) have been found to be effective for the treatment of osteoporosis, while showing decreased side effects. Analogues showing this effect include all sequences from hPTH-(1-28)-NH.sub.2 to hPTH-(1-31)-NH.sub.2 and all sequences from [Leu.sup.27 ]-hPTH-(1-28)-NH.sub.2 to [Leu.sup.27 ]-hPTH-(1-33)-NH.sub.2. Also included are cyclic analogues cyclo(Lys.sup.26 -Asp.sup.30) [Leu.sup.27 ]-hPTH-(1-34)NH.sub.2 and cyclo (Lys.sup.27 -Asp.sup.30 )-hPTH-(1-34)-NH.sub.2. Analogues in the form of the carboxyl terminal amide are particularly effective.
