Regulation of DNA base prototropic tautomerism by prolonation: quantum chemical data

Studies on Prototropic Tautomerism in Neutral and Monoanionic Forms of Pyrimidines by Nuclear Magnetic Resonance Spectroscopy

NMR methods have been applied to evaluation of prototropic tautomerism, N (1)H ^ N (3) H. in several selected pyrimidines, viz. the neutral forms of isocytosine and 2-alkylthiopyrimidone-4, and the monoanionic forms of uracil, 5-fluorouracil and 4-thiouracil. The predominant tautomeric species of the neutral forms could be estimated only qualitatively from chemical shifts. For the monoanionic f...

Experimental and theoretical study of enol-keto prototropic tautomerism and photophysics of azomethine-BODIPY dyads.

In this study we report about two novel azomethine–BODIPY dyads 1 and 2. The two dyads have been, respectively, synthesized by covalent tethering of tautomeric ortho-hydroxy aromatic azomethine moieties including N-salicylideneaniline (SA) and N-naphthlideneaniline (NA) to a BODIPY fluorophore. Both of the two dyads 1 and 2 show enol-imine (OH) structures dominating in the crystalline state. Dy...

DNA Base Data Hiding Algorithm

Proposing an algorithm by using software point of view for the purpose of implementing data hiding based on DNA sequences to increase the complexity is the main target of this paper. The implementation of algorithm is applicable because of some interesting characteristics of DNA sequences. Both of DNA’s features and Binary Coding Technology beside Complementary Pairing Rules are explained throu...
