CAS 25121-04-4: (11β,16β)-11-Chloro-17,21-dihydroxy-16-methylpregna-1,4-diene-3,20-dione

Description: The chemical substance known as (11β,16β)-11-Chloro-17,21-dihydroxy-16-methylpregna-1,4-diene-3,20-dione, with the CAS number 25121-04-4, is a synthetic steroid compound that belongs to the class of corticosteroids. It features a complex steroid structure characterized by multiple functional groups, including hydroxyl (-OH) and chloro (-Cl) substituents, which influence its biological activity and pharmacological properties. This compound is primarily recognized for its anti-inflammatory and immunosuppressive effects, making it relevant in therapeutic applications, particularly in the treatment of various inflammatory conditions. The presence of the chlorine atom and hydroxyl groups enhances its potency and alters its metabolic pathways compared to other corticosteroids. Additionally, its structural modifications contribute to its unique pharmacokinetic profile, affecting absorption, distribution, metabolism, and excretion. As with many corticosteroids, careful consideration of dosage and potential side effects is essential in clinical use to mitigate risks associated with long-term administration.
