Abstract
More information is needed to fully comprehend how acid mine drainage (AMD) affects the phototransformation of antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in karst water and sewage-irrigated farmland soil with abundant carbonate rocks (CaCO3) due to increasing pollution of AMD formed from pyrite (FeS2). The results showed FeS2 accelerated the inactivation of ARB with an inactivation of 8.7 log. Notably, extracellular and intracellular ARGs and mobile genetic elements (MGEs) also experienced rapid degradation. Additionally, the pH of the solution buffered by CaCO3 significantly influenced the photo-inactivation of ARB. The Fe2+ in neutral solution was present in Fe(II) coordination with strong reducing potential and played a crucial role in generating •OH (7.0 μM), which caused severe damage to ARB, ARGs, and MGEs. The •OH induced by photo-Fenton of FeS2 posed pressure to ARB, promoting oxidative stress response and increasing generation of reactive oxygen species (ROS), ultimately damaging cell membranes, proteins and DNA. Moreover, FeS2 contributed to a decrease in MIC of ARB from 24 mg/L to 4 mg/L. These findings highlight the importance of AMD in influencing karst water and sewage-irrigated farmland soil ecosystems. They are also critical in advancing the utilization of FeS2 to inactivate pathogenic bacteria.

Abstract
Imidazolone (Iz) is one of the many products resulting from oxidative damage to DNA. Three pathways for the formation of Iz and related degradation products have been studied by density functional theory using the ωB97XD functional with the 6-31+G(d,p) basis set and SMD implicit water solvation plus a small number of explicit water molecules positioned to help stabilize charged species and facilitate reaction steps. The first pathway starts with guanine radical and the addition of superoxide at C5. Endoperoxide formation was calculated to have slightly lower barriers than diol formation. The next steps are pyrimidine ring opening and decarboxylation. Ring migration then proceeds via an acyclic intermediate rather than a bicyclic intermediate and is followed by formamide loss to yield Iz. The second pathway starts with 8oxoG and proceeds via C5 superoxide addition and diol formation to a relatively stable intermediate, oxidized guanidinohydantoin (Ghox). The barriers for hydroxide ion addition to Ghox are much lower than for water addition and should yield more Iz and parabanic acid at higher pH. The third pathway starts with 8-hydroxy guanine radical formed by hydroxyl radical addition to C8 of guanine or water addition to C8 of guanine radical. Superoxide addition at C5 is followed by diol formation, ring opening and decarboxylation similar to pathways 1 and 2, subsequently leading to Iz formation. The calculated pathways are in good agreement with experimental observations.

Abstract
Oxidative damage to DNA leads to a number of two-electron oxidation products of guanine such as 8-oxo-7,8-dihydroguanine (8oxoG). 5-Carboxyamido-5-formamido-2-iminohydantoin (2Ih) is another two-electron oxidation product that forms in competition with 8oxoG. The pathways for the formation of 2Ih have been studied by density functional theory using the ωB97XD functional with the 6-31+G(d,p) basis set and SMD implicit water solvation plus a small number of explicit water molecules positioned to help stabilize charged species and facilitate reaction steps. For oxidative conditions that produce hydroxyl radical, such as Fenton chemistry, hydroxy radical can add at C4, C5, or C8. Addition at C4 or C5 followed by loss of H2O produces guanine radical. Guanine radical can also be produced directly by oxidation of guanine by reactive oxygen species (ROS). A C5-OH intermediate can be formed by addition of superoxide to C5 of guanine radical followed by reduction. Alternatively, the C5-OH intermediate can be formed by hydroxy radical addition at C5 and oxidation by 3O2. The competition between oxidative and reductive pathways depends on the reaction conditions. Acyl migration of the C5-OH intermediate yields reduced spiroiminodihydantoin (Spred). Subsequent water addition at C8 of Spred and N7-C8 ring opening produces 2Ih. Hydroxy radical addition at C8 can lead to a number of products. Oxidation and tautomerization produces 8oxoG. Alternatively, addition of superoxide at C5 and reduction results in a C5, C8 dihydroxy intermediate. For this species, the low energy pathway to 2Ih is N7-C8 ring opening followed by acyl migration. Ring opening occurs more easily at C8-N9 but leads to a higher energy analogue of 2Ih. Thus, the dominant pathway for the production of 2Ih depends on the nature of the reactive oxygen species and on the presence or absence of reducing agents.
