1. Ruthenium(II) nitrosyls as radical scavenger / Nitrosilo complexos de rutênio(II) como captores de radicais de interesse biológico
The complexes trans-[Ru(NO)(NH3)4(L)](X)3 (1), [Ru(NO)(Hedta)] (2) and their synthetic precursors trans-[Ru(H2O)(NH3)4(L)](X)2 (3), trans-[Ru(SO4)(NH3)4(L)](X) (4) , where L = isn, nic, imN, 4-pic, py, P(OEt) e X = PF6 - and BF4 -, were tested as scavengers for the radicals DPPHo, OHo e O2 -o in aqueous media. The redox potential for the metal center in the
