A KISS1R agonist peptide compound capable of inducing ovulation in a female mammal is provided. The compound is a pseudopeptide having the C-terminal sequence: -XaaΨ[Tz]Xaa2-Xaa3-Xaa4-NH
2
(SEQ ID NO: 3), where Ψ[Tz] represents a 1,4-disubstituted 1,2,3-triazole group replacing the peptide bond between the Xaa1 residue and the Xaa2 residue, Xaa1 is Gly or Ala, Xaa2 is Leu or an aliphatic α-aminoacyl analogue residue, Xaa3 is Arg, Arg(Me) or a positively charged α-aminoacyl analogue residue, and Xaa4 is Tyr, Phe, Trp or an α-aminoacyl analogue residue such as aryl alanine; or an analogue of the pseudopeptide in which the amide peptide bond between Xaa2 and Xaa3 and/or between Xaa3 and Xaa4 is replaced with an isosteric bond, or a salt thereof.
提供了一种KISS1R激动剂肽化合物,能够诱导雌性哺乳动物排卵。该化合物是一个伪肽,具有C-末端序列:-XaaΨ[Tz]Xaa2-Xaa3-Xaa4-NH2(SEQ ID NO: 3),其中Ψ[Tz]代表1,4-二取代1,2,3-三唑基团替换Xaa1残基和Xaa2残基之间的肽键,Xaa1为Gly或Ala,Xaa2为Leu或脂肪族α-氨基酰类似物残基,Xaa3为Arg,Arg(Me)或带正电荷的α-氨基酰类似物残基,Xaa4为Tyr,Phe,Trp或类似芳基丙氨酸的α-氨基酰类似物残基;或替代Xaa2和Xaa3之间和/或Xaa3和Xaa4之间的酰胺肽键的等构键或其盐。
