Patent AT-E400261-T1: [Translated] USE OF HISTONE DEACETYLASE INHIBITORS TO INCREASE THERAPEUTIC EFFECTS IN RADIOTHERAPY AND CHEMOTHERAPY

Published by National Center for Biotechnology Information (NCBI) | U.S. Department of Health & Human Services | Catalog Last Checked: July 31, 2026 at 09:05 PM | Dataset Last Updated: September 06, 2025
The present invention provides compositions and methods for increasing therapeutic gain in radiotherapy and chemotherapy for proliferating malignant or nonmalignant disease to produce high probability of tumor control with low frequency of sequelae of therapy by administering a therapeutically effective amount of a histone deacetylase inhibitor. The compounds are capable of simultaneously stimulating the epithelium regrowth, inhibiting the fibroblast proliferation, decreasing the collagen deposit, suppressing the fibrogenic growth factor, subsiding the proinflammatory cytokine and modulating the expression of cell cycle genes, tumor suppressors and oncogenes, and are useful to increase the therapeutic gain in radiotherapy and chemotherapy, which results in decrease of skin swelling and inflammation, promotion of epithelium healing in mucosa and dermis, decrease of xerostomia, prevention/reduction of severity of plantar-palmar syndrome, prevention of tissue fibrosis, ulceration, necrosis and tumorigenesis, and increase of tumor growth inhibition and tumor therapy effectiveness.
