| Research Abstract |
We have developed pH-responsible DNA cleaving agents using fused-cyclobutanols as precursors activated via ring contraction rearrangement. It is important for improvement of reactivity to design molecules stabilizing cation intermediates. In addition, we found that benzo-fused cyclobutanol showed DNA cleavage activity and this activity was stronger with higher concentration and more acidic pH condition. Further investigation about DNA alkylation mechanism and higher active compounds are ongoing in our laboratory.
