Carubicin is primarily used in the field of oncology as an antineoplastic agent. It is employed in chemotherapy to treat various types of cancer, particularly hematologic malignancies such as leukemia. The compound works by intercalating into DNA, thereby inhibiting the replication process of cancer cells and leading to their destruction. Its application is often considered in cases where other anthracycline drugs may be less effective or when specific patient conditions warrant its use. Due to its potent mechanism of action, careful monitoring is required to manage potential side effects, including cardiotoxicity and myelosuppression.
