Anagrelide Impurity 4 with CAS No: 70380-54-0 is an impurity standard of Anagrelide. Anagrelide, a quinazolinone derivative, inhibits phosphodiesterase activity, particularly phosphodiesterase-III, leading to decreased platelet production in the bone marrow. Its chemical structure, with a quinazolinone core and chlorine substitutions, is crucial for its pharmacological activity. Anagrelide is employed in the treatment of essential thrombocythemia, a condition characterized by elevated platelet levels, by selectively reducing platelet production. Administered orally, it is often considered when other treatments are not well-tolerated, providing a targeted approach to managing platelet counts and mitigating the risk of thrombotic events in affected individuals.
