Osilodrostat phosphate Free Base

Osilodrostat phosphate free base (also known as osilodrostat or LC699) is a potent oral inhibitor of 11-hydroxylase (CYP11B1), an enzyme involved in the final step of cortisol biosynthesis in the adrenal cortex. By blocking this enzyme, it effectively reduces cortisol production, making it valuable in the management of conditions associated with excess cortisol. Synonyms include osilodrostat, LC699, and 11-hydroxylase inhibitor LC699. In industrial and pharmaceutical applications, osilodrostat phosphate free base is primarily used as an active pharmaceutical ingredient (API) intermediate in the production of drugs targeting endocrine disorders such as Cushings syndrome. It is also utilized in biochemical research for studying steroidogenesis pathways and adrenal enzyme inhibition, supporting drug discovery and development efforts in endocrinology.
