How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Altogether six tautomers of cytosine and three tautomers of cytidine and deoxycytidine are studied theoretically in the gas phase and in a microhydrated environment. Their structures are optimized at MP2/6–31 + G(d,p) level. The relative energies of the isolated and the hydrated tautomers included the correction to higher correlation energy terms e...
Abiotic synthesis of nucleobases and amino acids is of critical importance as it sheds light on potential prebiotic chemical reactions. During thermal decomposition of formamide in vacuum conditions, purine, cytosine, adenine, hypoxanthine, uracil, pterin, urea, urocanic acid, glycine, alanine and norvaline were detected. The compounds were obtaine...
Fluorescent and computational methods were used to elucidate the binding expedient of 2‐carbamido‐1,3‐indandione (CAID) tautomers to nucleotides. The dependence of the fluorescence emission of CAID loaded nucleic acids sequences to compound concentration, temperature and time variation was investigated. It was found that the subject compound binds...
Among the most common infections are those caused by human herpes viruses, including Herpes Simplex virus type 1 and type 2 (HSV-1 and HSV-2) spread worldwide. Common therapies for herpes infections employ nucleoside analogues, such as acyclovir, and target the viral DNA polymerase, essential for viral DNA replication. Systemic application of these...
To provide an in-depth insight into the molecular basis of spontaneous tautomerism in DNA and RNA base pairs, a hybrid Monte Carlo (MC)–quantum chemical (QC) methodology is implemented to map two-dimensional potential energy surfaces along the reaction coordinates of solvent-assisted proton transfer processes in guanosine and its analog acyclovir i...
