Abstract:
:Fluorinated derivatives of 1,4-naphthoquinones are highly potent inhibitors of Cdc25A and Cdc25B phosphatases and growth of tumor cells. Eight new derivatives of polyfluoro-1,4-naphthoquinone were synthesized and their cytotoxicity in human myeloma, human mammary adenocarcinoma, mouse fibroblasts and primary mouse fibroblast cells as well as their mutagenic and antioxidant properties in a Salmonella tester strain were studied. The efficiency of suppressing the growth of two lines of tumor cells decreased in the order: 2-(2-hydroxy-ethylamino)-3,5,6,7,8-pentafluoro-1,4-naphthoquinone (1), 2,3-dimethoxy-5,6,7,8-tetrafluoro-1,4-naphthoquinone (2), 2-[2-hydroxyethyl(methyl)amino]-3,5,6,7,8-pentafluoro-1,4-naphthoquinone (3), 2-morpholino-3,5,6,7,8-pentafluoro-1,4-naphthoquinone (4), 2-[bis-(2-hydroxyethyl)amino]-3,5,6,7,8-pentafluoro-1,4-naphthoquinone (5), 2-[(2-hydroxy)ethylsulfanyl)]-5,6,7,8-tetrafluoro-1,4-naphthoquinone (6), 2-methoxy-3,5,6,7,8-pentafluoro-1,4-naphthoquinone (7), and 1,4-dioxo-3-(1-pyridinio)-1,4-dihydro-5,6,7,8-tetrafluoronaphthalene-2-olate (8). Taking into account these data together with the better cytotoxic effect against cancer cells as compared with normal mammalian cells, protecting of bacterial cells from spontaneous and H(2)O(2)-dependent mutagenesis, and lower general toxicity of the compounds towards different cells, one can propose that compounds 3-5 may be considered as useful potential inhibitors of growth of tumor cells.
