Abstract

Two novel 2,2,6,6-tetramethylpiperidine derivatives (Tempace and Troxyl) were synthesized and their capacity to act as scavengers of superoxide, inhibitors of iron and ascorbate-driven Fenton reaction and radioprotectors was tested. The possibility for one-electron oxidation of novel compounds by heme-ferryl species was also examined. The results clearly indicate that Tempace and Troxyl are acting as promising antioxidants and radioprotectors thus providing a base for further investigations and pharmacological applications.
