MedKoo Cat#: 201823 | Name: Acyline

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Acyline is a novel GnRH antagonist found in animal studies to be a potent suppressor of circulating gonadotropin and testosterone (T) levels. Acyline inhibits basal and GnRH-stimulated serum testosterone concentrations in male dogs. Acyline prevented ovulation, but did not affect ovarian follicular development or gestational corpora lutea in the domestic cat. A single dose of the potent gonadotropin-releasing hormone antagonist acyline suppresses gonadotropins and testosterone for 2 weeks in healthy young men.

More Info
Acyline is currently being developed by Merrion Pharmaceuticals. Acyline is a GnRH antagonist that takes advantage of GIPET® technology and provides an oral dosage form alternative to current therapies, all of which are injectable. There are several GnRH antagonists either marketed or in development for the treatment of prostate cancer, endometriosis and benign prostatic hypertrophy (BPH). In general, these new compounds are less potent than the first generation agonists, and cause greater local tissue irritation when used in a long acting injection or subcutaneous implant delivery systems. The market adoption of the currently approved products has been low due to the fact that a small percentage of patients develop a severe allergic response to the large doses given by injection of subcutaneous depot. An oral product would eliminate the inconvenience of injection therapy, avoid the severe reactions, and allow tailored dosing regimens. Merrion has identified a potent GnRH antagonist with an attractive product profile for development as an oral dosage form for the treatment of prostate cancer as an initial indication. This compound is a novel chemical entity and has already been evaluated in Phase II clinical trials. s ee : http://www.merrionpharma.com/content/portfolio/mer104.asp
