Abstract
Origin of cancer is strongly related to the unusual epigenetic regulation of gene function as indicated by recent reports. The covalent modifications to DNA or histones without affecting genomes that finally lead to phenotypical changes in cells or organisms are referred as “Epigenetics.” The possibility to reprogram the epigenetics in the cancer epigenome is the most important target for cancer treatment and drug resistance. The development of epigenetic drugs holds a great potential for the current cancer therapeutic approaches. Nevertheless, targeting cancer epigenetic pathways is still exciting due to the lack of selective and effective small molecule compounds or drug molecules. Therefore, the current book chapter highlights epigenetic pathways for cancer and potential small molecule inhibitors and epidrugs targeting DNA methyltransferase, histone modification, and more new therapies with nanomaterials and imaging to improve the effectiveness of cancer treatment. The structural aspects on discovery of novel small molecules or drugs targeting epigenetic pathways in cancer exploration as promising strategies will be also discussed.
