Gonadorelin acetate Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Gonadorelin Acetate is another name for gonadotropin-releasing hormone (GnRH). It is a synthetic decapeptide prepared using solid phase peptide synthesis.
Gonadorelin, also known as GnRH or LHRH, is produced by neuroendocrine cells within the hypothalamus. The hormone is secreted pulsatilely. Gonadorelin induces the release of LH and FSH from the anterior pituitary.
After a transient increase, continuous administration of gonadorelin results in downregulation of LH and FSH levels followed by a suppression of ovarian and testicular steroid biosynthesis.
Verwenden
Gonadorelin Acetate is used in various agricultural and biological studies. It was used in the study of ovulation synchronization in dairy cows.
Application
Ovarian follicular cysts (veterinary medicine)
Use in reproduction medicine
Diagnosis of the hypothalamic-pituitary-gonadal axis function
Cryptorchism
Synchronization of ovulation (veterinary medicine)
Indications
Gonadorelin is a synthetic decapeptide with a structure identical with the natural Gonadotrophin Releasing Hormone (Gn-RH) in mammalian species.
Gonadorelin is recommended for the treatment of reproductive disorders associated with ovarian cysts and for improvement of fertility in cows and for the induction of ovulation in rabbits. The mechanism of action underlying the therapeutic use is the stimulation of the release from and also the synthesis of LH and FSH in the anterior pituitary gland.
Biologische Aktivität
Gonadorelin is a tropic hormone and agonist of the gonadotropin-releasing hormone receptor (GNRHR; Ki = 13 nM in CHO cells expressing the human receptor). It stimulates luteinizing hormone (LH) and follicle- stimulating hormone (FSH) release from rat anterior pituitary cultures when administered at a dose of 0.1 μg. It also stimulates LH release from bovine anterior pituitary cultures at a concentration of 1 μM. In vivo, gonadorelin induces ovulation in rats pretreated with fluphenazine (Item No. 23555; ED50 = 610.3 ng/kg). Formulations containing gonadorelin have been used as diagnostic agents to assess pituitary gland function.
