Abstract

The speciation of the anti-tumor drug Metvan, [VIVO(Me2phen)2(SO4)], suggested that forc(V) > 50 μM, [VO(Me2phen)(citrH−1)]2−and the ternary complexes VO–Me2phen–Protein should be the major species at pH 7.4, while forc(V) < 10 μM, (VO)(hTf) is formed, Me2phen is lost and the conversion of VIVO to VVO/VVO2may occur.
