Popis: | The synthesis of a new amphiphilic nitrone, A, derived from a digalactosyl tris(hydroxymethyl)aminomethane bearing a perfluorocarbon chain is described. A exhibited a surfactant behavior (cmc = 1.6 x 10(-)(5) mol/L), and the specific recognition of the galactosyl moiety grafted on A by the KbCWL1 membrane lectin was established. Preliminary experiments showed that A was able to trap free radicals in aqueous media, the shape of the observed ESR spectra being strongly dependent upon the nature of the trapped free radical. |
