Resumo
The interaction of gold(III) complexes AuCl4–, Au(bipy)Cl2+, Au(en)23+ and Au(C9H19N4)2+ with methionine (HMet) in an aqueous solution (pH 2.0 и 7.4; I = 0.2 M (NaCl), CAu = (5–10) × 10–5 M, CHMet < (6–50) × 10–5 M) at 25°C was studied. Methionine reduces gold(III) to gold(I), but the processes proceed much more slowly (hundreds of times) than under the action of thiols. As the density of ligands in the gold(III) complex increases, the rate of reactions with HMet decreases significantly.
