詳細

Amino Acid Sequence

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

アプリケーション

[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

生物化学的／生理学的作用

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.

特徴および利点

その他のLH-RHアゴニストと比較して脂溶性が高いにもかかわらず、水に対する溶解性も保持しています。
