Definitions
- the present invention relates to the field of improving fertility in mammals. More particularly, the present invention relates to a peptide compound agonist of the KISS1R receptor capable of improving this fertility, as well as the use of such a compound as a medicament, in particular for improving fertility in mammals, and a veterinary composition and/or or pharmaceutical containing it.
- the peptide compound according to the invention finds particular application both in the field of animal husbandry and in that of human therapy.
- the methods currently used to induce ovulation at any time during the off-season and/or to synchronize ovulation within herds rely on the use of steroid hormones, such as progesterone or estradiol, prostaglandin F2 ⁇ (PGF2 ⁇ ) and PMSG (for English Pregnant Mare Serum Gonadotropin, equine chorionic gonadotropin).
- steroid hormones such as progesterone or estradiol, prostaglandin F2 ⁇ (PGF2 ⁇ ) and PMSG (for English Pregnant Mare Serum Gonadotropin, equine chorionic gonadotropin).
- PPF2 ⁇ prostaglandin F2 ⁇
- PMSG for English Pregnant Mare Serum Gonadotropin, equine chorionic gonadotropin
- the methods currently used to induce ovulation in sheep provide for the implantation for 12 to 14 days of a vaginal sponge containing progesterone, combined with co-treatment by an injection intramuscular PMSG at the time of sponge removal.
- an injection of PGF2 ⁇ must be carried out 6 days after the vaginal implantation of a device containing progesterone, which must be followed the day after the removal of this vaginal device.
- Such processing is cumbersome to implement.
- the treatments currently available for medically assisted procreation have certain undesirable side effects, such as ovarian hyperstimulation. These treatments also use hormones to induce ovulation, and therefore act either at the level of the pituitary or at the level of the gonads.
- KISS1R will be used to designate both the human receptor and the receptor of other species (indicated by the abbreviation Kiss1r in the official nomenclature).
- the kisspeptide also called kisspeptin
- the kisspeptide-10 primarily responsible for the biological stimulatory activity of KISS1R is the decapeptide called kisspeptin-10, or KP10.
- kisspeptin-10 derived from the mouse (mKP10, Mus musculus, of sequence: Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Tyr-NH2 (SEQ ID No: 1 ) in which the C-terminus is modified by amidation) and human-derived kisspeptin-10 (hKP10, Homo sapiens, sequence: Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu- Arg-Phe-NH2 (SEQ ID No: 2) in which the C-terminus is also modified by amidation).
- Ewe-derived kisspeptin-10 is notably identical to mKP10.
- KISS1R The activation of KISS1R by these ligands, and more particularly by KP10, induces a very powerful stimulatory effect on the release of LH and FSH hormones in mammals, this effect resulting from an increase in the secretion of GnRH (for l 'English Gonadotropin Releasing Hormone, pituitary gonadotropin releasing hormone) (Caraty and Franceschini, 2008, Reprod. Dom. Anim. (Suppl. 2): 172-178).
- KP10 administered to ewes intravenously at the end of the follicular phase, is capable of inducing a peak in luteinizing hormone (LH) which is followed, 21 hours later, by synchronized ovulations at hour (Caraty et al., 2007, Endocrin. 148(11): 5258-5267). It has also been shown that during the period of sexual rest (seasonal anestrus), prolonged infusion of KP10 is able to reactivate the gonadotropic axis and induce ovulation (Sébert et al., 2010, Domest. Anim. Endocrinol .38(4): 289-298).
- LH luteinizing hormone
- KISS1R human immunosensus sarcoma
- the KISS1R humans and sheep also show a very high degree of homology, with more than 60% identity, and kisspeptides (or kisspeptins) show similar in vivo activity in primates and sheep (Seminara et al. , 2006, Endocrinology 147(5): 2122-2126; Caraty et al., 2007, cited above), which makes it possible to envisage an application in human therapy.
- KP10 has the particular advantages of being very quickly eliminated from the body and easily destroyed in the natural environment, leaving only amino acids as residues.
- KP10 has a mechanism of action, resulting in the triggering of the secretion of the LH hormone necessary for the induction of ovulation, which is completely different from that of current treatments, and which allows a more localized action. and fine avoiding unwanted side effects.
- KP10 is rapidly degraded and excreted by the body, it has a limited duration of action. It has therefore been sought by the prior art to develop compounds derived from KP10 which have a prolonged and controlled duration of action in the body, while retaining properties of degradability in the environment similar to those of KP10. .
- Document WO 2014/118318 in particular describes peptide compounds agonists of the KISS1R receptor derived from KP10, exhibiting a strong capacity for inducing / synchronizing ovulation in mammals, in which a peptide bond within the KP10 peptide is replaced by a 1,2,3-triazole-1,4-disubstituted group.
- the publication by Camerino et al., International Journal of Peptide Research and Therapeutics, 2008, 14(4): 323-331 and document WO 2013/136338 both describe derivatives of kisspeptin which are macrocyclized.
- the cyclization is carried out there, respectively, by a lactam bridge formed between the residues located in positions 4 and 8 of the peptide chain, and by a disulphide bridge linking the N-terminal and C-terminal amino acid residues of this chain.
- the present invention aims to provide non-steroidal compounds which have properties which are further improved compared to these compounds proposed by the prior art, and which, in particular, combine the advantages of a strong fertility-enhancing effect, including a strong ability to induce/synchronize ovulation in female mammals, and a prolonged duration of action in the body. Additional objects of the invention are that these compounds are easy to synthesize and at low cost, and that they exhibit low toxicity for living organisms and for the environment.
- the present inventors have also taken an interest in derivatives of kisspeptins. They discovered that cyclic derivatives of kisspeptin-10 responding to a particular structure exhibit, surprisingly, a very good activation efficiency of the KISS1R receptor as well as, compared to the linear derivatives of this kisspeptin proposed by the prior art , a prolonged effect, more gradual over time.
- the present invention provides a peptide compound agonist of the KISS1R receptor, chosen from: - a compound of formula (I): R 1 -Xaa1-Xaa2-Xaa3-Asn-Xaa4-Phe-Xaa5 -Xaa6-Xaa7-Xaa8-NH2 (I) in which the C-terminal end is modified by amidation, Xaa5 and one, preferably only one, of the residues Xaa1, Xaa2 or Xaa3, both simultaneously represent either a cysteine residue, either a D-cysteine residue, the sulfur atoms of said cysteine residues or of said D-cysteine residues, that is to say of Xaa5 and of one of Xaa1, Xaa2 and Xaa3, being linked to one another other covalently via a disulphide, methylene, cis-but-2-enylene, m
- the term “pharmaceutically acceptable salt”, in a conventional manner per se, means any salt of the compound of formula (I) or of its analogue comprising, as counterion, a substance which does not produce any adverse, allergic or otherwise undesirable reaction when administered to a subject, particularly a mammal. Any conventional pharmaceutically acceptable salt of the compound of formula (I) or of its analogue can be used according to the invention. By way of examples, mention may be made of chlorides, bromides, formates, acetates, etc.
- the positions of the amino acids in the peptides are defined in a manner conventional in itself, the numbering starting at the level of the N-terminal end of the peptide, appearing on the left in all the sequences, while the C-terminal end appears on the right.
- the peptide compound according to the invention is thus such that two residues located in specific positions within the KP10 peptide are replaced simultaneously by cysteine residues or by D-cysteine residues, these cysteine or D-cysteine residues being linked, at the level their respective sulfur atoms, covalently via an arm, called a "clip", so as to achieve macrocyclization of the peptide compound, this clip having a particular chemical formula, chosen from: - a disulphide bridge, - a methylene bridge, of formula: - a cis-but-2-enylene bridge, of formula: - an m-xylylene bridge, of formula: - a p-xylylene bridge, of formula: - and a 2,5-dichloro-p-xylylene bridge, of formula: the reasons in these formulas representing the bonds to the sulfur atoms of the cysteines or D-cysteines residues.
- the peptide compound according to the invention advantageously has a very powerful stimulatory effect on the release of the luteinizing hormone LH in a female mammal, in particular much stronger than cyclized peptide compounds of similar structure but not falling within the formula ( I), in particular by the structure of the clip, the position of the amino acid residues substituted by the cysteine or D-cysteine residues, and even in which one amino acid residue is substituted by a cysteine and the other by a D-cysteine.
- the peptide compound according to the invention has a prolonged duration of action in vivo.
