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...

biotransformation of benzo[a]pyrene (bap) in the presence of microsomal fractions derived from liver and epiderm of adult and weanling rats was examined. the aim of this study was to evaluate the effect of age on the capacity of two organs in transformation of bap. subcellular fractions were prepared from skin and liver by ultracentrifugation and were used as the source of bap metabolizing enzy...

Transcription factors bind specifically to their target elements in the genome, eliciting specific gene expression programs. The nuclear factor-?B (NF-?B) system is a family of proteins comprising inducible transcription activators, which play critical role inflammation and cancer. NF-?B members function as dimers with each monomeric unit binding ?B-DNA. Despite available structures various com...

Cobalt(II)  complexes of isonicotinoyl hydrazones of two series of ligands have been synthesized and characterized on the basis of elemental analyses, molar conductance, magnetic moment, mass, IR, UV spectral data. Electrochemical behavior of ligands and complexes has been investigated by using cyclic voltammetry. Cyclic voltammetric studies reveal that the oxidation/reduct...

A new click chemistry generated artificial metallonuclease is reported in the Research Article by Andrew Kellett et al. (e202305759). The oxidative DNA damaging properties of a polynuclear copper binding ligand called TC-Thio demonstrated. Copper-TC-Thio binds minor groove genomic and promotes damage via superoxide linked mechanism. inset picture shows ions, bound to ligand, melting into duplex...
