Determination of redox potentials for the Watson-Crick base pairs, DNA nucleosides, and relevant nucleoside analogues
Article Abstract:
Redox potentials for the DNA nucleobases and nucleosides, various relevant nucleoside analogues, Watson-Crick base pairs and seven organic dyes are determined. It was found that nucleosides with anti conformation display lower oxidation potentials than the corresponding syn conformers due to the formation of an intramolecular hydrogen bonding interaction between the 5'-OH group of the sugar and the N(3) of the purine bases or C(2)=O of the pyrimidine bases in the syn conformation.

Comprehensive theoretical study of the conversion reactions of spiropyrans: substituent and solvent effects
Article Abstract:
A comprehensive theoretical study of the reaction mechanisms for the conversion between spiropyrans (SPs) and the open form of merocyanines (MCs) is conducted. The reaction mechanisms on the ground- and triplet-state potential energy surfaces (PESs) are investigated.
