Novak, Igor published the artcileElectronic structure and biological activity of nucleobases, Formula: C5H6N2O2, the publication is Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (2005), 61A(11-12), 2771-2774, database is CAplus and MEDLINE.
HeI and HeII photoelectron spectra of 6-chloro-1,3-dimethyluracil have been measured. The assignment of the spectrum was made by comparison with photoelectron spectra of related compounds and by high-level OVGF calculations The electronic structure changes in substituted nucleobases are discussed on the basis of photoelectron spectroscopic data. The electronic structure data are compared with structure-activity relationships regarding enzyme inhibition and complex formation. The electronic structure data give some insight into the nature of binding between nucleobases’ derivatives and different enzymes whose activity they inhibit.
