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

GnRH analog (GnRHa) therapy for central precocious puberty (CPP) typically involves im injections. The histrelin implant is a new treatment that provides a continuous slow release of the GnRHa histrelin. The objective of the study was to investigate the safety

Standard treatment of central precocious puberty (CPP) consists of intramuscular or subcutaneous administration of a gonadotropin-releasing hormone (GnRH) agonist (GnRHa) at 3- to 4-week intervals. Although generally effective in suppressing clinical and laboratory parameters of puberty, GnRHa injections are painful

It is well known that many anurans do not reproduce easily in captivity. Some methods are based on administration of mammalian hormones such as human chorionic gonadotropin, which are not effective in many frogs. There is a need for simple

Comparative analyses between amphibians, concentrating on the cellular mechanisms of morphogenesis, reveal a large variability in the early developmental processes that were thought to be conserved during evolution. Increased egg size is one factor that could have a strong effect
