Csendes Z, Bugris V, Lacko L, Labadi I, Kiss JT, Palinko I: Superoxide dismutase mimicking Cu (II)-mixed amino acid complexes covalently grafted onto silica gel-an FT-IR study. Anal Bioanal Chem. 2010 Jan 15.
Our recent work concerning the synthesis, characterisation and testing of bioinspired electron transfer catalysts is described in this contribution. The catalysts were various Cu (II) complexes having mixed C- or N-protected amino acids (L: -histidine and L: -tyrosine) as ligands covalently grafted onto surface-modified silica gel. The resulting materials were structurally characterised by FT-IR spectroscopy, and their superoxide dismutase activities were tested. The covalently anchored Cu (II) complexes displayed appreciable activities in the test reaction; thus, they may be considered as promising candidates as durable electron transfer catalysts approaching the efficiency of the enzyme mimicked. |
