Some porphyrin (Fe)-intercalators were synthesized. We chose 2-aminodipyrido[1, 2-a:3',2'-d]imidazoles (Glu-P's), which were muta-carcinogens isolated from a pyrolysate of L-glutamic acid, as intercalator moieties. These synthetic porphyrin (Fe)-intercalators cleave DNA at G-C and G-T sequences. The specificity for cleavage of base sequences of DNA is quite similar to that of bleomycin.
