It was shown previously, that millimolar concentrations of ascorbate have cytotoxic and anti-proliferative effects (Eur. J. Clin. Invest. 32 (2002) 372). With increasing concentrations of ascorbate an increasing number of fibroblasts was detached from the culture dish and shown to be lysed by the effect of ascorbate-induced generation of reactive oxygen species (ROS-s). It also could be shown, that this cytotoxic effect is partly due to the dose-dependent inhibition by ascorbate of fibronectin biosynthesis. Superoxide dismutase (SOD) and catalase were shown to salvage cells from ROS-induced cell-death by preventing the inhibition of fibronectin biosynthesis. We used this model system to test the cyto-protective effect of L-fucose and fucose-rich oligo- and polysaccharides (FROP-s). It appeared that relatively low concentrations of L-fucose and FROP-3 (Biomed. Pharmacother. in press) could efficiently protect fibroblasts from the ascorbate-induced cell-death. These novel pharmacological properties of L-fucose and FROP-3 might well be related to their accelerating effect of wound healing.
