Amino Acid Sequence

Glp-His-Trp-Ser-Tyr-Leu-Leu-Arg-Pro-NHEt

Application

In mice, leuprolide acetate salt has been used to check the need of estrogen receptor α in spermatogenic cells, for development or function in fertilization.

Actions biochimiques/physiologiques

Glp-His-Trp-Ser-Tyr-Leu-Leu-Arg-Pro-NHEt (des-Gly10-[D-Leu6]-LH-RH) is a GnRH (gonadotropin-releasing hormone) agonist, leuprolide. 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. Low concentration of leuprolide can be used for the treatment of endometriosis, uterine fibroids, central precocious puberty and advanced prostate cancer.
