abstract

  • We report a facile iodine(iii)-mediated synthesis of cyanoporphyrins and their DNA photocleavage activity. Cationic-porphyrin 9a showed intercalative binding towards DNA, whereas Zn(ii)-cyanoporphyrinate 9b showed outside electrostatic binding as indicated by their absorption and emission spectra. Porphyrin 9a displayed significant photocytotoxicity against A549 cancer cell line with an IC50 value of 54 nM.
