Enzalutamide [CAS: 915087-33-1] is a nonsteroidal androgen receptor inhibitor treatingmetastatic castration-resistant prostate cancer. Enzalutamide acts as an antineoplasticagent and inhibits androgen activity.

Enzalutamide: Use and Commercial Availability 

Enzalutamide is a US FDA-approved medicine that treats patients with metastatic castration-resistant prostate cancer where hormone therapy has failed. Enzalutamide is sold under the brand name Xtandi.

Enzalutamide Structure and Mechanism of Action

The chemical name of Enzalutamide is 4-[3-[4-Cyano-3-(trifluoromethyl) phenyl]-5,5-dimethyl-4-oxo-2-thioxo-1-imidazolidinyl]-2-fluoro-N-methylbenzamide. Its chemical formula is C₂₁H₁₆F₄N₄O₂S, and its molecular weight is approximately 464.4g/mol.

Enzalutamide is an androgen receptor (AR) inhibitor, classified as a second-generation drug, and acts on various steps in the androgen receptor signaling pathway. It inhibits androgen binding to androgen receptors. In addition, it inhibits androgen receptor nuclear translocation and DNA interaction.

Enzalutamide Impurities and Synthesis

During its synthesis¹ or storage, impurities form in Enzalutamide, which can affect the drug’s efficacy and safety. Related substances, starting materials, intermediates, and degradation products are present as impurities in Enzalutamide. Impurity formation is due to impurities in the starting materials, poor reaction conditions, or exposure to light and heat during storage. Thus, it is essential to monitor and control Enzalutamide impurities to ensure the quality and safety of the drug.

Daicel offers a Certificate of Analysis (CoA) from a cGMP-compliant analytical facility for Enzalutamide impurity standards, including C-Desmethyl Enzalutamide acid impurity, Des Fluoro Enzalutamide, ENZ cyano desfluoro impurity, ENZ DIAMIDE Impurity, Enzalutamide Carboxylic Acid, N-Desmethyl Enzalutamide, Oxo- Enzalutamide, etc. The CoA includes complete characterization data, such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity^2,3. We also provide 13C-DEPT and CHN when requested. We also give a complete characterization report. Daicel has the technology and expertise to prepare any unknown Enzalutamide impurity or degradation product. We also provide labeled compounds to quantify the efficacy of generic Enzalutamide. Daicel offers Enzalutamide D3 and Enzalutamide D6, which are deuterated-labeled standards of Enzalutamide for bioanalytical research and BA/BE studies with isotope data in CoA.
