Glycyrrhizin(GL), is a triterpenoid saponin found in glychyrrhiza glabra (liquorice). This compound is a frequently used and very effective drug for the treatment of various malignancies. This study was designed to examine the interactions of glycyrrhizin with calf thymus DNA in aqueous solution at physiological conditions. FTIR spectroscopic method was used to determine the ligand binding mode...

background: dna damage is one of the major consequences of radiation exposure onto the biological systems. a series of compounds including flavanoids were found to render dna protection against radiation damage. in this study we elucidated the potential of rutin and rutin hydrate to protect plasmid dna against damage induced by irradiation. materials and methods: dpph and hydroxyl radical scave...

Abstract The syntheses of [Cu(PPh 3 ) 2 (L)]NO and (L-SO Na)]NO were achieved through the reaction Cu(PPh NO equimolar amount ligands (L = 5,6-diphenyl-3-[2-pyridyl]-1,2,4-triazine; LSO Na 5,6-diphenyl-3-[2-pyridyl]-1,2,4-triazine-4,4?-disulfonic acid disodium salt). complexes characterized by NMR IR spectroscopy mass spectrometry. compounds exhibit similar absorption emission spectra, suggesti...
