Amino Acid Sequence

Glp-His-Trp-Ser-Tyr-Trp-Leu-Arg-Pro-Gly-NH2

Application

[D-Trp6]-LH-RH (luteinizing hormone releasing hormone) has been used to study whether the (M. – X) region in electron capture dissociation provides information on amino acid composition of polypeptides. It is also used to study the effect of LH-RH on the production of progesterone (P), estradiol (E2) or human chorionic gonadotropin (hCG) by JEG-3 choriocarcinoma cells.

Biochem/physiol Actions

Potent LH-RH agonist with enhanced biological activity due to its slower rate of degradation. Like [D-Lys6]-LH-RH, the D-Trp6 analog has been shown to be effective against cancers expressing the LH-RH receptor. However, unlike the D-Lys6 analog, it is generally used in the unconjugated form.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

GNRH significantly inhibits proliferation of a proportion of cancer cell lines by activating GNRH receptor (GNRHR)-G protein signaling. Therefore, manipulation of GNRHR signaling may have an under-utilized role in treating certain breast and ovarian cancers. However, the precise signaling pathways

Although slow release GnRH-agonist implants have been shown to effectively suppress the estrous cycle in queens, there are still several remaining questions about their use: if the probability and frequency of estrus induction because of initial stimulation is dependent on

The neuropharmacological actions of the agonist analog D-Trp-6-LH-RH were investigated in several tests after intracerebroventricular (ICV) administrations to male rats. The doses applied were 10, 100 and 1000 ng/animal. In the open field the 1000 ng ICV dose of the

Over the last 10-15 years, long-acting GnRH agonists have become widely available. In the field of small animal reproduction, most recent studies have focused on the use of two compounds developed under the form of subcutaneous implants: azagly-nafarelin and deslorelin.
