ct-DNA Binding and Antibacterial Activity of Octahedral Titanium (IV) Heteroleptic (Benzoylacetone and Hydroxamic Acids) Complexes

Figure 6

(a) Absorption spectrum of ct-DNA without complex (4) having concentration 0.19 mM (A) and complex (4) adduct with ct-DNA with varying concentration of ct-DNA 0.20 mM (B) and 0.23 mM (C). The arrow indicated the increasing concentration of ct-DNA. The graph represents the plot of versus 1/[DNA] (mM)⁻¹ for the calculation of binding constant (). (b) Absorption spectrum of ct-DNA with complex (4) after 24 h incubation.
