This paper deals with the synthesis of a novel series of amphiphilic glycosylated spin-traps derived from alpha-Phenyl-N-tert-butyl nitrone (PBN) and an initial characterization of their anti-caspase-3 activity. Preliminary investigation of their anti-apoptosis effect showed they dramatically inhibit the activity of caspase-3 in cultured neuronal cells following induction of apoptosis by hydrogen peroxide.

Synthesis and Preliminary Biological Evaluations of Ionic and Nonionic Amphiphilic α-Phenyl-<i>N</i>-<i>tert</i>-butylnitrone Derivatives
In this study we report the synthesis of a series of new amphiphilic compounds derived from alpha-phenyl-N-tert-butylnitrone (PBN). The nitrone function was fitted into the core of the molecule between its polar and apolar groups. The polar head consisted of a lactobionamide, an ammonium, or a carboxylate group. The hydrophobic part consisted of a hydro- or a perfluorocarbon chain. The hydrophobic
