  2. Epigenetic drugs are generally epigenetic enzyme inhibitors, affecting DNA and histone modifications and leading to chromatin structure changes. Most epi-drugs listed above are in preclinical and clinical development, and two DNMT inhibitors, four HDAC inhibitors, two IDH inhibitors, one EZH2 inhibitor, and one LSD1 inhibitor have been approved by the FDA available for standard-of-care treatment for cancer. However, these epi-drugs are mainly used to treat cancers, and only a small number of epi-drugs have been studied in terms of BMSC anti-aging and osteogenesis. Further research is needed
