Stabilization of Poly(dA)[poly(dT)]2 Triplex by Anthryl and Acridine Derivatives: Effect of Side Chanis and Nitrogen Atom on the Polycyclic Aromatic Ring
Gil-Jun Lee, Chang-Beom Cho, Dong-Jin Lee, Joon-Won Park, Seog K. Kim
The effects of anthryl derivatives and 9-aminoacridine on the thermal melting profile of a poly(dA)[poly(dT)]₂triplex were compared 9-Aminoacridine stabilizes the triplex far more effectively than anthryl derivatives. The absorption and CD and LD spectroscopic characteristics of anthryl derivatives are similar to those of 9-aminoacridine when complexed with the triplex; the N atom of acridine, which can act as a hydrogen bond acceptor, plays an important role in triplex stabilization.
