| Outline of Final Research Achievements |
Aberrant DNA methylation and histone modification cause major epigenetic changes and have been implicated in cancer growth. While drugs for epigenome such as SAHA and decitabine can be available for cancer treatment, site-specific modification of epigenome is now requested to be technically achieved. Pyrrole-imidazole polyamides are small molecules that can be designed to recognize and bind to particular DNA sequences. In this study, we synthesized PIP-LSD1 inhibitor conjugates and investigated whether the conjugates show site-selective changing of histone methylation. The results in this study indicate that PIP-inhibitor conjugates induced histone methylation where single inhibitor could not change. In addition, it is shown that PIP can act as sequence-specific antagonists of CpG methylation in living cells.
