Interaction of [Ru(dmp)(2)(dppz)(2+) and [Ru(dmb)(2)(dppz)](2+) with DNA: Effects of the ancillary ligands on the DNA-binding behaviors
By the incorporation of methyl groups on the ancillary ligand of phen and bpy, different DNA-binding behaviors of complexes 1 and 2 were characterized. Different binding rates of the isomers of 2 with CT-DNA via CD spectra were observed through dialysis experiments but not with complex 1.
