PTH2 receptor selective compounds
View Patent ↗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.
1. A human PTH analogue of the formula, [Cha 7,11 , des-Met 8 , Nle 18 , Tyr 34 ]hPTH(1-34)NH 2 (SEQ ID NO:16), which selectively binds to the PTH2 receptor, or a pharmaceutically acceptable salt thereof.
2. A human PTH analogue which selectively binds to the PTH2 receptor, wherein said analogue is selected from the group consisting of
[Cha 7,11 , des-Met 8 , Nle 18 , Tyr 34 ]hPTH(1-34)NH 2 (SEQ ID NO:16),
[Cha 7,11 , D-Nle 8 , des-Met 18 , Tyr 34 ]hPTH(1-34)NH 2 , and
[Cha 7,11 , D-Nle 8 , Nle 18 , Tyr 34 ]hPTH(1-34)NH 2 ,
which selectively binds to the PTH2 receptor, or a pharmaceutically acceptable salt thereof.
3. A pharmaceutical composition comprising an analogue according to claim 2 or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier.
