The interaction between pyropheophorbide methyl ester (PPME) and Cu 2+ was investigated using UV-vis and fluorescence spectrscopy. Study of the binding interaction between PPME and Cu 2+ could contribute to understanding of its pharmacokinetics and pharmacodynamics. Parameters of the static and dynamic fluorescence quenching of PPME- Cu 2+ association were calculated at different temperatures. For binding site of 1:1 at 299 K, the static binding constant (kS), the static isosbestic concentration ([Formula: see text]), the dynamic binding constant (kD), and the dynamic isosbestic concentration ([Formula: see text]) are, respectively, 61 M-1, 0.0164 M, 75 M-1, and 0.0133 M. The concentrations and efficiencies of the intermediates species were modeled. Satisfactory correspondence between the experimental and calculated results was found.
