Abstract:

Triplex DNA can interfere with gene transcription and expression modulation. It is one kind of important biological macromolecules. The interaction between small molecules and DNA targets plays an important role in the function of drug mediated physiological processes. In the past decades, numerous attempts have been made to screen triplex DNA binders. However, not too many effective methods for screening triplex DNA binders were reported. Basic principles, the screening methods of research and application for the interaction between small ligands and triplex DNA were summarized, including mainly the principle and application of several methods, such as competition dialysis, gold nanoparticle based approach, thermal denaturation method, centrifugal ultrafiltration method, electrospray ionization mass spectroscopy(MS) method, and liquid chromatography-mass spectroscopy(LC-MS) combined method. This review has a general instruction to the research of the interaction between small ligands and triplex DNA.

Key words: ligands, triplex DNA, stability, screening method, application
