Abstract:
:The synthesis and antioxidant activity of oligo(ethylene glycol)-modified manganese salen complexes are reported. Their SOD activities were similar and 2- to 3-fold more potent than the standard compound EUK-134. Their catalase-like activity was lower than that of EUK-134 in the initial conversion rate; however, some analogs exhibited a better catalytic turnover number.
