A natural DNA-intercalator plant benzo-c-phenanthridine alkaloid sanguinarine is more toxic for mouse transformed fibroblast L-cells in culture than synthetic DNA-intercalator ethidium bromide (EtB) and alkaloid berberine. Dimidium bromide is also an inhibitor of the L-cell growth. In assay conditions, growth...
