Abstract: The interactions of five kinds of 1,4-dihydropyridine(1,4-DHP) derivatives with calf thymus DNA(CT-DNA) were investigated by the electrochemical method and circular dichroism(CD). The results indicated that the interaction between 1,4-DHP derivatives and CT-DNA was in the intercalative mode. The strength of the interaction increases with the decrease in the steric hindrance of 1,4-DHP derivatives. DNA double helix in solution become more loose in the presence of non-planar structure 1,4-DHP derivatives.

Key words: Dihydropyridine derivatives, DNA, Electrochemistry, Circular dichroism, Oxidation peak, DNA conformation
