Abstract: A water-soluble porphyrin tetrakis[4-(trimethylammoniumly)phenyl]porpyrin (TAPP) and its metalloporphyrin derivatives MTAPP with M=Zn(Ê),Cu(Ê),Fe(Ë),Co(Ë),Ni(Ê),Mn(Ë), containing various functional groups within the porphyrin have been synthesized and characterized by elemental analysis, and UV-Vis spectra. Binding of TAPP and Zn-TAPP with calf thymus DNAwas investigated by absorption spectra, fluorescence spectra and viscosity measurements. Addition of CT DNAresulted in obvious hypochromism and bathochromic of 12 nm in absorption spectra, and an enhancement in fluorescence spectra were also observed. The anticancer activities of these complexes were also tested by MTTon two mice tumor cells of Ac and Hept, the results indicated that Co(Ë)-TAPPshowed a high inhibitory action and high anticancer activity in cell.
