Genomic integrity is constantly threatened by sources of DNA damage, internal and external alike. Among the most cytotoxic lesions is the DNA double-strand break (DSB) which arises from the cleavage of both strands of the double helix. Cells boast a considerable set of defences to both prevent and repair these breaks and drugs which derail these processes represent an important category of anticancer therapeutics.

The Watson-Crick DNA double helix is an averaged ideal of multitudinous natural sequence-directed local structural deviations. By effectively derailing normal cellular physiological processes, damaged bases can induce noncanonical irregularities in the local structure of DNA if not efficiently repaired. Pyrimidine bases, especially thymine, are prone to dimerization when exposed to ultraviolet light.
