Abstract
A series of polysulfones of new structural types on the basis of azanorbornenes, 2,2-diallyl-1,1,3,3-tetraethylguanidiniumchloride and tris(diethylamino)diallylaminophosphonium salts were obtained by free radical polymerization reaction. Their antioxidant properties in lipid peroxidation induced by iron/ascorbate and in erythrocyte hemolysis by H2O2 were evaluated. The polysulfone of 2,2-diallyl-1,1,3,3-tetraethylguanidinium chloride showed protection of erythrocytes against hydrogen peroxide and thermal shock, protected epithelial cells against UV irradiation, was not toxic for erythrocytes, epithelial cells SPEV and 3T3 fibroblasts. The polysulfone of N-benzyl-2-azanorbornene-5 inhibited lipid peroxidation in liver homogenate, did not exhibit cytotoxicity in SPEV and 3T3 cells, protected these against UV irradiation. Both compounds had low bioavailability and may be recommended for further investigations as excipients to be externally applied.
