Purines and pyrimidines have long been recognised as fundamental elements of bioenergetics; while their role as chemical transmitter was suggested 90 years ago, when in 1929, Albert Szent-Gyorgyi and Alan Drury discovered that intravenous injection of adenine into guinea pig disturbed cardiac rhythm, ...
Examples are presented of natural nucleosides which exhibit appreciable tautomerism in solution, e.g. formycins A and B, isoguanosine, but are not found in DNA. Illustrations are given of synthetic promutagenic nucleosides with pronounced tautomerism in solution relevant to their role in mutagenesis...
The present examples show that purines drive neural stem cell expansion, and that purine receptor activation is required for stem cells to be maintained as such. Neural progenitors expressed P2Y purinergic receptors and mobilized intracellular calcium in response to an agonist. Receptor antagonists ...
Seven examples are modeled as Watson–Crick base pairs but should be Hoogsteens (commonest at duplex termini), and three had the opposite issue. Syn/anti flips were also needed for some single-stranded purines. Five of the 20 convincing cases arose from an unmodeled alternate duplex running ...
Examples of patterning will be presented, including the patterning of the DNA base adenine with the subsequent reading of the pattern using a chemically functionalized thymine AFM tip, and the spatially confined adsorption of lysozyme.University of Washington.Boland, Thomas....

In our study, we decided to enhance their solubility, especially in water, and synthesize pyridinium salts of 2-piperidinyl-6-triazolylpurine derivatives, and then examine how much the fluorescence is quenched upon introduction of pyridine moieties in the structure. There are a few examples in the...
