ABSTRACT:
The present invention discloses a photo-induced DNA-cleaving agent composition comprises N-aryl-N-(alkyl or arylalkyl)hydroxylamine having the following formula: ##STR1## wherein R is C.sub.1 -C.sub.6 alkyl, phenyl, C.sub.1 -C.sub.6 alkoxy, phenoxy, C.sub.1 -C.sub.6 alkoxycarbonyl, halogen or halo(C.sub.1 -C.sub.6 alkyl)wherein R.sub.1 is hydrogen, C.sub.1 -C.sub.6 alkyl, phenyl, C.sub.1 -C.sub.6 alkoxy, C.sub.1 -C.sub.6 alkoxycarbonyl, halogen or halo(C.sub.1 -C.sub.6 alkyl); R.sub.2 is hydrogen; R.sub.3 is hydrogen or phenyl; R.sub.4 is hydrogen, phenyl, hydroxylphenyl, methoxyphenyl, dimethoxyphenyl, dimethylaminophenyl or naphthyl. The present N-aryl-N-(alkyl or arylalkyl)hydroxylamine is stable in dark, but it can react with O.sub.2 to form HO.multidot. radicals under irradiation of UV light for a period of 2-3 hours. The HO.multidot. radicals then react with DNA to accomplish cleavage of DNA.
