Metabolite Identification
Common NameCetrorelix
DescriptionCetrorelix, also known as cetrotide or SB 75, belongs to the class of organic compounds known as polypeptides. These are peptides containing ten or more amino acid residues. Cetrorelix is a drug which is used for the inhibition of premature lh surges in women undergoing controlled ovarian stimulation. When undergoing hormone treatment sometimes premature ovulation can occur, leading to eggs that are not ready for fertilization to be released. Due to a positive estradiol (E2) feedback at midcycle, GnRH liberation is enhanced resulting in an LH-surge. Cetrorelix is a very strong basic compound (based on its pKa). Cetrorelix competes with natural GnRH for binding to membrane receptors on pituitary cells and thus controls the release of LH and FSH in a dose-dependent manner. Cetrorelix does not allow the premature release of these eggs to occur. Cetrorelix is a synthetic decapeptide with gonadotropin-releasing hormone (GnRH) antagonistic activity. Cetrorelix was transformed by peptidases, and the (1-4) peptide was the predominant metabolite. Cetrorelix is a man-made hormone that blocks the effects of Gonadotropin Releasing Hormone (GnRH).

General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
Receptor for gonadotropin releasing hormone (GnRH) that mediates the action of GnRH to stimulate the secretion of the gonadotropic hormones luteinizing hormone (LH) and follicle- stimulating hormone (FSH). This receptor mediates its action by association with G-proteins that activate a phosphatidylinositol- calcium second messenger system. Isoform 2 may act as an inhibitor of GnRH-R signaling
