Intercalators. 1. Nature of Stacking Interactions between Intercalators (Ethidium, Daunomycin, Ellipticine, and 4‘,6-Diaminide-2-phenylindole) and DNA Base Pairs. Ab Initio Quantum Chemical, Density Functional Theory, and Empirical Potential Study

Properties of isolated intercalators (ethidium (E), daunomycin (D), ellipticine (EL), and 4,6‘-diaminide-2-phenylindole (DAPI)) and their stacking interactions with adenine···thymine (AT) and guanine···cytosine (GC) nucleic acid base pairs were investigated by means of a nonempirical correlated ab i...
