Application

Guanosine is a purine nucleoside that upon sequential phosphoylation (kinases) forms GTP which is used by RNA polymerases to synthesis RNA(s). GTP is also important in a wide range of GTPase-dependent cell signaling processes. Guanosine is used in selective matricies such a guanosine gels (G-gels) for use in capillary electrophoresis chiral selection and other applications.

Novel square-planar palladium(II) complexes with O-N-N-O-type ligands H4mda (H4mda=malamido-N,N'-diacetic acid) and H4obp (H4obp=oxamido-N,N'-di-3-propionic acid) were prepared and characterized. The ligands coordinate to the palladium(II) ion via two pairs of deprotonated ligating atoms with square chelation. A four coordinate, square-planar geometry...

Immune sensing of DNA is critical for antiviral immunity but can also trigger autoimmune diseases such as lupus erythematosus (LE). Here we have provided evidence for the involvement of a damage-associated DNA modification in the detection of cytosolic DNA. The oxidized base...

G-quadruplex-forming oligonucleotides containing modified nucleotide chemistries have demonstrated promising pharmaceutical potential. In this work, we systematically investigate the effects of sugar-modified guanosines on the structure and stability of a (4+0) parallel and a (3+1) hybrid G-quadruplex using over 60 modified...

Nature's use of a simple genetic code to enable life's complex functions is an inspiration for supramolecular chemistry. DNA nucleobases carry the key information utilizing a variety of cooperative and non-covalent interactions such as hydrophobic, van der Waals, pi-pi stacking...
