POH3 is designed to specifically bind with triplex DNA, resulting in a turn-on fluorescence response, and can be developed into a catalytic triplex DNAzyme for porphyrin metalation. The catalytic activity is initiated by the enhanced basicity of POH3 upon binding with the triplex DNA.
Trihydroxyphenyl porphyrin (POH3) was designed to specifically bind with a triplex DNA resulting in a turn-on fluorescence response. This ensemble can be developed into a catalytic triplex DNAzyme towards porphyrin metalation. The catalytic activity is initiated by the enhanced basicity of POH3 upon binding with the triplex DNA.
