title: Extended ethidium bromide analogue as a triple helix intercalator: synthesis, photophysical properties and nucleic acids binding.
abstract: Ethidium bromide has been extended by fusing an additional aromatic ring resulting in a larger intercalator with increased affinity for poly r(A) x r(U), poly d(A) x d(T) and triple helices when compared to the parent heterocycle.
