DNA Binding and Cleavage Activities of Na[B(Glu)(OH)2]·2H2O, Na[B(Cit)(OH)2]·2H2O, Li[B(Sal)(OH)2], and Mg[B(Sal)(OH)2]·2H2O Complexes
Figure 1
(a) Electronic absorption spectra of complex 1 (100 μM) with increasing amounts of DNA 1 (11.2 μg) and DNA 2 (22.5 μg). (b) Electronic absorption spectra of complex 2 (100 μM) with increasing amounts of DNA 1 (11.2 μg) and DNA 2 (22.5 μg). (c) Electronic absorption spectra of complex 3 (100 μM) with increasing amounts of DNA 1 (11.2 μg) and DNA 2 (22.5 μg). (d) Electronic absorption spectra of complex 4 (100 μM) with increasing amounts of DNA 1 (11.2 μg) and DNA 2 (22.5 μg). Arrows show the changes in absorbance with respect to an increase in DNA concentration.
