Abiraterone Acetate (CAS 154229-18-2): Properties and Applications

Abiraterone acetate, identified by the Chemical Abstracts Service registry number 154229-18-2, represents a significant therapeutic agent in oncology, particularly for metastatic prostate cancer. The chemical structure is that of a prodrug, meaning it requires metabolic conversion within the body to the active form, abiraterone. Chemically its properties, abiraterone acetate exists as a white to off-white powder, possessing limited solubility in water but increased solubility in organic solvents like ethanol or dimethyl sulfoxide. The molecular formula is C<sub>26</sub>H<sub>30</sub>O<sub>3</sub>, and its molecular weight is approximately 402.51 g/mol. Mainly, abiraterone acetate functions as an inhibitor of CYP17A1, an enzyme crucial for androgen biosynthesis. This action reduces the production of testosterone in the testes, adrenal glands, and prostate cancer tissues themselves, as a result disrupting cancer cell growth.

• Therapeutic applications are concentrated in treating castration-resistant prostate cancer (CRPC) often alone or in combination with other treatments.
• Other research is exploring its potential use in earlier stages of prostate cancer and in different types of cancers.

Ultimately, abiraterone acetate serves a vital role in improving outcomes for patients with advanced prostate cancer.
