This review summarizes recent theoretical advancements in predicting and interpreting the reactivity of nucleic acid bases, focusing on understanding the inherent fragmentation pathways of isolated nucleobases and modeling realistic nano-environments. It highlights the importance of molecular dynamics simulations and the non-innocent role of the environment in potentially opening novel fragmentation pathways.
The effects of radiations on nucleic acids and their constituents is widely studied across several research fields using different experimental and theoretical protocols. While a large number of studies were performed in this context, many fundamental physical and chemical effects are still being investigated, particularly involving the effect of the biological environment. As an example, the interpretation of experimental nucleic acid bases mass spectra, and hence inferring their reactivity in complex environment still poses great challenge. This Minireview summarizes recent theoretical advancements aiming to predict and interpret the reactivity of nucleic acid bases. We focus not only on the understanding of the inherent fragmentation pathways of isolated nucleobases but also on the modeling of a realistic nano-environments highlighting the importance of molecular dynamics simulations and the non-innocent role of the environment and also the possibility to open novel fragmentation pathways.
