Disproportionation and Nuclease Activity of Bis[2-ethyl-2-hydroxybutanoato(2-)]oxochromate(V) in Neutral Aqueous Solutions

Levina, Aviva; Lay, Peter; Dixon, Nicholas


Complex 1, [Cr(V)O(ehba)2]- (ehba = 2-ethyl-2-hydroxybutanoate(2-)) is the most studied model compound of relevance to the biological activity of Cr(V) with regard to Cr-induced cancers. The first detailed kinetic study of disproportionation of 1 under neutral pH conditions (pH 6.0-8.0, [NaClO4] = 1.0 M, 37 °C) is reported. Kinetic data were collected by stopped-flow and conventional UV-vis spectroscopies and processed by the global analysis method. The disproportionation, which follows the...[Show more]
