    • 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.
    • 本发明涉及肽激素类似物作为其各自天然存在的肽激素的抑制剂的用途。 肽激素类似物的结构以甲状旁腺激素(PTH)为例,其中Lys13被取代以增加PTH类似物的生物学活性。 因此,公开了具有下式的肽:PTH(7-34)NH 2; [Tyr34] PTH​​(7-34)NH2; [D-Trp12,Tyr34] PTH​​(7-34)NH2; [Nle8,18,D-Trp12,Tyr34] PTH​​(7-34)NH2; [Nle8,18,Tyr34] PTH​​(7-34)NH2; 脱氨基[Nle8,18,D-Trp12,Tyr34] PTH​​(7-34)NH 2; 和脱氨基[Nle8,18,D-Trp12,Tyr34] PTH​​(8-34)NH2,其中Lys13在ε-氨基酸基团中被N,N-二异丁基或3-苯基丙酰基修饰。
