  Rational Design of Triazololipopeptides Analogs of Kisspeptin Inducing a Long-Lasting Increase of Gonadotropins

  摘要：

  New potent and selective KISS1R agonists were designed using a combination of rational chemical modifications of the endogenous neuropeptide kisspeptin 10 (KP10). Improved resistance to degradation and presumably reduced renal clearance were obtained by introducing a 1,4-disubstituted 1,2,3-triazole as a proteolysis-resistant amide mimic and a serum albumin-binding motif, respectively. These triazololipopeptides are highly potent full agonists of KISS1R and are >100 selective over the closely related NPFF1R. When injected in ewes with a quiescent reproductive system, the best compound of our series induced a much prolonged increase of luteinizing hormone release compared to KP10 and increased follicle-stimulating hormone plasma concentration. Hence, this KISS1R agonist is a new valuable pharmacological tool to explore the potential of KP system in reproduction control. Furthermore, it represents the first step to develop drugs treating reproductive system disorders due to a reduced activity of the hypothalamo-pituitary-gonadal axis such as delayed puberty, hypothalamic amenorrhea, and hypogonadotropic hypogonadism.

  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.
