| Abstract: Three water-soluble copper porphyrin complexes (water-soluble bromine-containing copper porphyrin CuP-1 and its bromine substituted derivatives CuP-2 and CuP-3) have been synthesized and characterized by 1H NMR, elementary analysis and MS spectra. The interaction of CuP-1, CuP-2 and CuP-3 with CT-DNA have been investigated by UV spectrum, EB-DNA fluorescence quenching, viscosity method and circular dichroism spectrum. Moreover, the antitumor activities of CuP-1~CuP-3 against Hela (cervical cancer) cell lines and MDA (breast carcinoma) cell lines have been studied by MTT assay. L929 (human fibroblast) cell line was used as a normal cell lines. Various spectroscopic approaches indicates that CuP-1 could effectively bind with CT-DNA through intercalation mode, while CuP-2 and CuP-3 may interact with CT-DNA by outside groove binding mode. And the binding affinity of CuP-1 with CT-DNA is better than its derivatives CuP-2 and CuP-3. In vitro antitumor activity experiments showed that CuP-1~CuP-3 can inhibit the growth of Hela and MDA cell lines, and the inhibition shows concentration and time dependent. In addition, antitumor activity in vitro of CuP-1 is much better than CuP-2 and CuP-3. |
