Abstrakt: The antiamyloidogenic capacity of water-soluble nitroderivatives of fullerene C60: methyl ester of LN-[(2-nitroglyceryl) fullerenyl] proline, methyl ester of LN-[(2,3-dinitroglyceryl) fullerenyl] proline, and 2 nitroxyethyl ether LN-([2-(nitroxy) ethyl] fullerenyl) proline has been studied in vitro by high-resolution electron microscopy. It was shown that these fullerene C60 nitroderivatives are able to prevent the formation of amyloid fibrils by the brain Abeta(1-42)-peptide and muscle X-protein and to destroy mature fibrils. Electron microscopy is a promising method for selecting effective antiamyloidogenic drugs. The antiamyloidogenic activity of nanodimensional fullerene C60 nitroderivatives offers strong possibilities for creating a new nanotechnology for the therapy of amyloidoses.
