“…Non-covalent DNA adducts can be highly stable and persistent, and, in some cases, lead to replication blockage and apoptosis. In addition to this role, they can act as photosensitizers and exacerbate the toxicity of other stress sources, such as UV light or ionizing radiation [ 26 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. Sensitizers can act either via the production of O [ 36 ], via energy transfer, usually from the triplet manifold [ 28 , 30 , 37 , 38 ], or via electron transfer, usually towards guanine [ 39 , 40 ].…”
