Elagolix [CAS: 834153-87-6], an orally bioavailable, second-generation compound, is a selective antagonist of the gonadotropin-releasing hormone (GnRH; LHRH) receptor. It is a small molecule, a non-peptide-based compound that inhibits hormone production. This medication treats moderate to severe pain associated with endometriosis.

Elagolix: Use and Commercial Availability 

Elagolix, available under Orilissa, is an oral GnRH antagonist that effectively suppresses pituitary-ovarian hormones in a dose-dependent manner. It can partially control ovarian estrogen production at lower doses. Elagolix effectively inhibits the production of gonadotropins and estrogen. It also reduces average endometrial thickness without affecting the serum anti-Müllerian hormone (AMH) level.

Elagolix Structure and Mechanism of Action

The chemical name of Elagolix is 4-[[(1R)-2-[5-(2-Fluoro-3-methoxyphenyl)-3-[[2-fluoro-6-(trifluoromethyl)phenyl]methyl]-3,6-dihydro-4-methyl-2,6-dioxo-1(2H)-pyrimidinyl]-1-phenylethyl]amino]butanoic acid. Its chemical formula is C₃₂H₃₀F₅N₃O_5, and its molecular weight is approximately 631.6 g/mol.

Elagolix binds to GnRH receptors in the pituitary gland and inhibits endogenous GnRH signaling. Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are controlled. It leads to a decrease in blood concentration of progesterone and estradiol.

Elagolix Impurities and Synthesis

The analysis and control of impurities in Elagolix, a pharmaceutical compound, are vital to ensure its quality and safety. During the synthesis^1,2, storage, or degradation of Elagolix, various impurities may arise that can impact its efficacy or pose potential risks. Th extensive analysis is conducted to identify and quantify these impurities, enabling their control within acceptable limits. Strict control measures throughout the manufacturing process help minimize impurity levels and maintain the desired quality of Elagolix. It includes adherence to appropriate storage conditions, stringent manufacturing practices, and regular quality assessments to ensure the safety and effectiveness of the final product.

Daicel Pharma offers a comprehensive Certificate of Analysis (CoA) for Elagolix impurity standards, including Desbutyrate Elagolix, Elagolix Desfluoro Impurity 1, Elagolix Enantiomer Impurity, Elagolix Impurity B, Elagolix Impurity-C, Elagolix Impurity D, Elagolix Sodium Impurity-E, and more. They generate from an analytical facility that complies with cGMP standards. The CoA provides a detailed characterization report with data obtained through techniques such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity analysis³. We provide additional data like 13C-DEPT upon request. Daicel Pharma synthesizes unknown Elagolix impurities or degradation products. Elagolix-D6, a deuterium-labeled Elagolix standard, is available for bio-analytical research, including BA/BE studies. Every delivery has a complete characterization report.
