(D-Trp6)-LHRH-Leu-Arg-Pro-Gly amide is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development[1].
Glp-His-Trp-Ser-Tyr-Trp-Leu-Arg-Pro-Gly-Leu-Arg-Pro-Gly-NH2 ([D-Trp6]-LH-RH-Leu-Arg-Pro-Gly-NH2) is a GnRH (gonadotropin-releasing hormone) agonist, triptorelin. GnRH (Glp-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH2), which is also referred as LHRH (luteinizing hormone-releasing hormone) or gonadorelin, is crucial for mammalian reproduction and is released from hypothalamic neurons. It is responsible for the secretion of gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), from the pituitary glands. Mutations in GnRH are associated with normosmic congenital hypogonadotropic hypogonadism. Triptorelin is used for the treatment of hormone-associated prostate and breast cancers, endometriosis, uterine fibroids, central precocious puberty and in vitro fertilization.
