Synthesis and Determination of Cerium(IV)-Reducing Antioxidant Capacity (CERAC) Assay of Some New Anthraquinones

Novel anthraquinone-based cyclic antioxidants containing amino, thio and oxo groups were synthesized their antioxidant capacity was determined by using the cerium(IV)-reducing (CERAC) assay. 1H, 13C NMR, FTIR-spectroscopy ESI (Electrospray Ionization) mass spectrometry used for characterization of anthraquinone derivatives exhibiting CERAC capacity. This study is great importance, because compounds analyzed first time method CERAC-Trolox equivalent (TEAC) values higher than that Trolox. It should also be noted that, since all have potential to find applications in terms biological properties due sulfur nitrogen content, they will make an important contribution literature.
