Abstract
6-Selenium bridged cyclodextrin was synthesized by regioselective tosy lation of beta-cyclodextrin and NaHSe displacement on the basis of the active site structure of glutathione peroxidase (GPX), The compounds displayed a higher activity of GPX than Ebselen (PZ51), its GPX activi ty was 4, 3 times more than that of PZ51, The structure of the mimic w as characterized by elemental analysis, IR and H-1 NMR, The Se content and its valence in the mimic was determined by X-ray photoelectron sp ectrum.
