The CT-DNA binding properties of these compounds have been investigated by thermal denaturation measurements, absorption and emission spectroscopy. The supercoiled pUC19 plasmid DNA cleavage activity of these compounds has been explored by agarose gel electrophoresis. The cytotoxicity of these compounds against MCF-7, Caco-2, A549 cancer cells and BEAS-2B healthy cells was also studied by using XTT method. The complexes 1-4 exhibit significant high cytotoxicity with low IC50 values in compared with cisplatin. The effect of the substituents of phen and coordinated amino acid in the above complexes are presented and discussed.eninfo:eu-repo/semantics/closedAccess1,10-Phenanthroline5-Nitro-1,10-phenanthrolineCopper(II)CytotoxicityDNA binding and cleavagel-TyrosineOxidative cleavage activityWeak-interactionsCrystal-structureAmino-acidsBindingFluorescenceDerıvativesMononuclearOrganotin(IV)Ruthenium(II)SpectroscopyAmino acidsBinding energyComplexationCoordination reactionsCopperCytotoxicityDNAElectrophoresisEmission spectroscopyNuclear magnetic resonance spectroscopyPlatinum compoundsSingle crystalsSynthesis (chemical)ThermoanalysisX ray diffraction1 ,10-phenanthroline5-Nitro-1,10-phenanthrolineAbsorption and emission spectroscopyAgarose gel electrophoresisDNA binding and cleavagesEffect of substitutionl-TyrosineSingle crystal x-ray diffractionCopper compoundsCell deathCell line, tumorCrystallography, X-RayDNADNA cleavageElectrophoresis, agar gelHumansInhibitory concentration 50LigandsMolecular conformationNucleic acid denaturationPhenanthrolinesSolubilitySpectrometry, fluorescenceSpectrophotometry, ultravioletTemperatureTyrosineWaterArticle0003537547000392-s2.0-8492510611531332414525795604SpectroscopyComplex; Viscometry; Schiff Bases1,10-phenanthrolineCalf thymus DNADNALigandPhenanthroline derivativeTyrosineWaterAgar gel electrophoresisCell deathChemistryConformationDNA cleavageDNA denaturationDrug effectsHumanIC50MetabolismSolubilitySpectrofluorometryTemperatureTumor cell lineUltraviolet spectrophotometryX ray crystallography
