Luteinizing hormone-releasing hormone antagonists.
BACKGROUND Luteinizing hormone-releasing hormone (LH-RH) plays a central role in the vertebrate reproduction by regulating gonadal activity. Based on its binding to pituitary LH-RH receptors, as well as to LH-RH receptors expressed on cancer cells, LH-RH agonists and antagonists have been developed for different therapeutic applications. OBJECTIVE/METHOD Here we give an overview of the most r...
متن کاملPulsatile administration of gonadotropin-releasing hormone agonist to gilts actively immunized against gonadotropin-releasing hormone.
Sexually mature gilts (n = 20) were actively immunized against GnRH. Primary and booster immunizations of GnRH conjugated to bovine serum albumin induced production of antibodies in all gilts. Nineteen of the gilts became acyclic with suppressed concentrations of gonadotropins and estradiol. Intravenous challenges with 100 micrograms GnRH and 5 micrograms D-(Ala6, des-Gly-NH2(10)) ethylamide Gn...
متن کاملGonadotropin-releasing hormone antagonists: novel members of the azaline B family.
A series of antagonists of gonadotropin-releasing hormone (GnRH) homologous to azaline B ([Ac-DNal1,DCpa2,DPal3,Aph5(Atz),DAph6+ ++(Atz),ILys8,DAla10]GnRH) was synthesized, characterized, and tested in a rat antiovulatory assay (AOA). Selected analogues were also tested in both an in vitro dispersed rat pituitary cell culture assay for inhibition of GnRH-stimulated luteinizing hormone release a...
متن کاملFunction of gonadotropin-releasing hormone in olfaction.
Gonadotropin-releasing hormone (GnRH) is present within neurons of the nervus terminalis, the zeroeth cranial nerve. In all vertebrate species, except in sharks where it is a separate nerve, the nervus terminalis consists of a chain of neurons embedded within olfactory or vomeronasal nerves in the nasal cavity. The function of the GnRH component of the nervus terminalis is thought to be neuromo...
متن کاملMathematical modeling of gonadotropin-releasing hormone signaling
Gonadotropin-releasing hormone (GnRH) acts via G-protein coupled receptors on pituitary gonadotropes to control reproduction. These are Gq-coupled receptors that mediate acute effects of GnRH on the exocytotic secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as the chronic regulation of their synthesis. GnRH is secreted in short pulses and GnRH effects on it...
