  • A comparison of the base-pair specificities of three phenanthridine drugs using solution spectroscopy.: This study evaluates the specificity of three phenanthridine drugs, including Dimidium bromide, in binding to DNA base pairs through solution spectroscopy techniques. The research offers significant insights into the interactions at the molecular level, providing valuable information for chemists involved in drug design and DNA interaction studies (Dougherty G, 1982).
