Abstract
Here, we developed a coralyne-based, 'light-up' intercalator displacement assay to identify molecular stabilizers of triplex DNA using a sequence from a chromosomal breakpoint hotspot in the human c-MYC oncogene. Its potential to identify triplex DNA ligands was demonstrated using BePI and doxorubicin. Identification of triplex-interacting ligands may allow the regulation of genetic instability in human genomes.
