Amino Acid Sequence

Glp-His-Trp-Ser-Tyr-His(Bzl)-Leu-Arg-Pro-NHEt

Application

[des-Gly10, D-His(Bzl)6]-LH-RH ethylamide has been used:
  • for inducing Batrachoseps gravid females to oviposit
  • for comparing the effect of LHRH (luteinizing hormone-releasing hormone) agonists and dopamine antagonists in Lithobates pipiens
  • for inducing oviposition in females of Taricha granulosa and Ensatina eschscoltzii
  • to induce spawning in Spea hammondii adults

Biochem/physiol Actions

Glp-His-Trp-Ser-Tyr-His(Bzl)-Leu-Arg-Pro-NHEt ([des-Gly10, D-His(Bzl)6]-LH-RH) is a GnRH (gonadotropin-releasing hormone) agonist, histerelin. 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. Histerelin is used for the treatment of central precocious puberty in children. It inhibits actions of sex steroids on the male and female reproductive organs.

Features and Benefits

Has greater lipophilicity than other LH-RH agonists, but retains high water solubility

In children with precocious puberty (PP), treatment with GnRH analogs (GnRHa) often decreases height velocity below normal. Based on previous animal studies, we hypothesized that this impaired growth is due to excessive advancement in growth plate senescence induced by the

Medical castration with long-acting GnRH-agonist (GnRHa) is a well-established treatment for metastatic prostate cancer. Our aim was to explore the relationships between FSH, inhibin B, anti-Mullerian hormone (AMH), and testosterone during treatment with an implant releasing GnRHa. Analysis of hormone
