| Outline of Final Research Achievements |
DNA repeat expansion disease is a class of human genetic disorders that arise from the vastly repeated DNA sequence such as three or five nucleotides. This study has aimed at the development of small molecular ligands that have low affinity to a single site but nonetheless, they accumulate to a multiple sites or repeated DNA site. Evaluation of cooperative binding has been investigated using the restriction enzyme AccII and DNA containing its substrate sequence. The ligands used in this study include natural product Chrmomycin A3 and the structure-simplified anthracenone derivatives. In conclusion, we have successfully demonstrated that the new synthetic ligands exhibit cooperative binding to the DNA with the multiple sequence.
