Used in cancer research, particularly for its potential in treating solid tumors and hematological malignancies. It functions as a histone deacetylase (HDAC) inhibitor, which helps reactivate silenced tumor suppressor genes. Often studied in combination with other therapies such as hormone therapy, immunotherapy, or chemotherapy to enhance anti-tumor effects. Shows promise in breast cancer, lung cancer, and melanoma by improving immune recognition of cancer cells and reducing tumor growth. Also investigated for its ability to reverse drug resistance in certain cancers.
