Photocleavage of DNA by 4'-bromoacetophenone analogs.
4'-Bromoacetophenone analogs, which are able to generate monophenyl radicals capable of hydrogen atom abstraction, were investigated as possible photoinducible DNA cleaving agents. The potential of 4'-bromoacetophenone as a possible new DNA cleaver is explored. Pyrrolecarboxatmid conjugated 4'-bromoacetophenones, in particular, DNA cleaving activity and sequence-selectivity on the contiguous AT base pair sites.
