This journal is The Royal Society of Chemistry 2015 Copper(II) complexes of salicylaldehydes and 2 hydroxyphenones: Synthesis, Structure, Thermal decomposition study and Interaction with calf thymus DNA and albumins Ariadne Zianna, George Psomas, Antonios G. Hatzidimitriou, Maria Lalia Kantouri * Department of General and Inorganic Chemistry, Faculty of Chemistry, Aristotle University of Thessaloniki, GR Thessaloniki, Greece Supplementary material S1. Interaction with CT DNA The binding constant, K b, can be obtained by monitoring the changes in the absorbance at the corresponding λ max with increasing concentrations of CT DNA and it is given by the ratio of [DNA] slope to the y intercept in plots versus [DNA], according to the Wolfe Shimer equation ( A f ) [1]: [DNA] [DNA] 1 (eq. S1) (ε ε ) (ε ε ) K (ε ε ) A f b f b where [DNA] is the concentration of DNA in base pairs, ε A = A obsd /[compound], ε f = the extinction coefficient for the free compound and ε b = the extinction coefficient for the compound in the fully bound form. b f S2. Competitive studies with EB The Stern Volmer constant K SV is used to evaluate the quenching efficiency for each compound according to the Stern Volmer equation: Io 1 KSV[Q] (eq. S2) I where Io and I are the emission intensities in the absence and the presence of the quencher, respectively, [Q] is the concentration of the quencher (i.e. complexes 1 6); K SV is obtained from the Io Stern Volmer plots by the slope of the diagram vs [Q].

2 S3. Interaction with serum albumins The extent of the inner filter effect can be roughly estimated with the following formula: I corr meas ( exc )cd 2 ( em )cd 2 I (eq. S3) where I corr = corrected intensity, I meas = the measured intensity, c = the concentration of the quencher, d = the cuvette (1 cm), ε(λ exc ) and ε(λ em ) = the ε of the quencher at the excitation and the emission wavelength, respectively, as calculated from the UV Vis spectra of the complexes [2]. The Stern Volmer and Scatchard graphs are used in order to study the interaction of a quencher with serum albumins. According to Stern Volmer quenching equation [3]: Io =1+ kq τ0[q] =1+ KSV[Q] (eq. S4), I where Io = the initial tryptophan fluorescence intensity of SA, I = the tryptophan fluorescence intensity of SA after the addition of the quencher, k q = the quenching rate constants of SA, K SV = the dynamic quenching constant, τ o = the average lifetime of SA without the quencher, [Q] = the concentration of the quencher, the dynamic quenching constant (K SV, M 1 ) can be obtained by the Io slope of the diagram vs [Q]. From the equation: I K SV = k q τ o (eq. S5) and taking τ o = 10 8 s as fluorescence lifetime of tryptophan in SA, the approximate quenching constant (k q, M 1 s 1 ) is calculated. From the Scatchard equation [3]: I Io nk K [Q] ΔI Io (eq. S6) where n is the number of binding sites per albumin and K is the association binding constant, K (in I M 1 ) is calculated from the slope in plots Io [Q] to the slope [3]. ΔI versus and n is given by the ratio of y intercept Io References [1] A. Wolfe, G. Shimer and T. Meehan, Biochemistry, 1987, 26, [2] L. Stella, A.L. Capodilupo and M. Bietti, Chem.
