Abstract: In this paper, three new Ruthenium(II) polypyridyl complexes containing ascididemin (ASC) as main ligand have been synthesized and characterized. Their interactions with different G-quadruplex (Htelo, c-myc and c-kit) (Htelo: human telomeric DNA, c-myc: cellular-myelocytomatosis viral… read more here.

Abstract: Abstract Quadruplex-duplex (Q–D) junctions constitute unique structural motifs in genomic sequences. Through comprehensive calorimetric as well as high-resolution NMR structural studies, Q–D junctions with a hairpin-type snapback loop coaxially stacked onto an outer G-tetrad were… read more here.
