The environment is modelled by sequential hydration of misonidazole clusters in vacuum. The well-defined experimental conditions enable computational modeling of the observed reactions. While the NO- 2 dissociative electron attachment channel is suppressed, as also observed previously for other molecules, the OH- channel remains open. Such behavior is enabled by the high hydration energy of OH- and ring formation in the neutral radical co-fragment. These observations help to understand the mechanism of bio-reductive drug action. Electron-induced formation of covalent bonds is then important not only for biological processes but may find applications also in technology.DF – Departamento de FísicaCeFITec – Centro de Física e Investigação TecnológicaRUNOnčák, MilanMeißner, RebeccaArthur-Baidoo, EugeneDenifl, StephanLuxford, Thomas F.
