Abstract: The present invention relates to agents, compositions and methods for use in medicine. In particular, the invention relates to agents related to GnRH peptides.

Abstract: The present invention relates to the use of an antagonist of kisspeptin in the manufacture of a medicament for the treatment of a condition induced and/or worsened by kisspeptin activity in an individual. The invention also provides certain defined peptide molecules, which may act as an antagonist of kisspeptin, which are of use in treating a condition induced and/or worsened by kisspeptin activity in an individual. In addition, the invention provides methods of identifying and/or using antagonists of kisspeptin and/or the defined peptides, and pharmaceutical compositions thereof.

Abstract: The invention describes a retro-inverso (RI) gonadotropin-releasing hormone (GnRH) peptide which is capable of eliciting an immune response directed against GnRH, the peptide having the amino acid sequence GPRLGYSWHX, wherein the amino acids are D-amino acids and X is any amino acid. More particularly, X is E, Q, P or G, and even more particularly, X is E or Q. Thus, a preferred amino acid sequence for the peptide is GPRLGYSWHE. The peptide may optionally include one or more additional D-amino acids at its N- or C-terminus, for example a cysteine residue or a series of linker amino acids, such as a plurality of glycine amino acid residues. Thus, a second preferred amino acid sequence for the peptide is GPRLGYSWHEC, which includes a cysteine residue at the C-terminus for conjugation purposes.

Abstract: A compound comprising a gonadotrophin releasing hormone analogue conjugated to a hormone moiety, or a derivative thereof, which is able to bind to a plasma hormone binding protein. The compounds may be used to treat hormone-dependent disorders such as cancer, or as a contraceptive.

Abstract: A method of combating menorrhagia, dysmenorrhoea or endometriosis in a female individual that includes administering to the individual at least one agent that reduces the effect of prokineticin 1 on a prokineticin receptor.

Abstract: A method of treating an individual with a condition which condition is one wherein the individual with the condition benefits from the administration of GnRH and/or a GnRH analogue, the method comprising administering to the individual GnRH and/or a GnRH analogue and an inhibitor of prostaglandin synthesis and/or a prostaglandin receptor antagonist. The methods of the invention also include combating a sex-hormone dependent disease in an individual, and regulating fertility in an individual.

Abstract: A method for identifying a test compound that has an anti-tumoral effect whilst not significantly activating unrelated transduction signals, the method comprising the steps of: (a) selecting at least one test compound; (b) assaying the compound for anti-tumoral effect; (c) selecting at least one distinct intracellular event which is modulated, at least partially, by the GnRH receptor; (d) testing for the ability of said test compound not to modulate the selected intracellular event; and (e) selecting the test compound which selectively demonstrates an anti-tumoral effect and does not modulate said other selected intracellular event.

Abstract: There is provided polynucleotides encoding the full sequence for the marmoset and human Type II gonadotropin-releasing hormone receptors (Type II GnRH-R). The corresponding amino acid sequences are also provided.
