Using an assembly method, dinuclear CoCo and CoFe complexes supported by a bdt ligand, [Cp*Co(μ-η2:η2-bdt)(μ-I)CoCp*][PF6] (1[PF6], Cp* = η5-C5Me5, bdt = benzene-1,2-dithiolate), and [Cp*Co(μ-η2:η4-bdt)FeCp'][PF6] (3[PF6], Cp' = η5-C5Me4H) were synthesized in high yields. Upon chemical reduction with CoCp2, complexes 1[PF6] and 3[PF6] were converted to [Cp*Co(μ-η2:η2-bdt)CoCp*] (2) and [Cp*Co(μ...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
Macrocyclic heterobinuclear Zn(II)–Cu(II) complexes with phenol based dicompartmental ligands possessing contiguous hexa- and penta-coordination sites were prepared by a stepwise procedure. The ligands include similar N4O2 and dissimilar N(imine)3O2 and N(amine)3O2 coordination sites sharing two phenolic oxygen atoms. The six-coordination site comprises two pyridyl pendant arms on the amine nit...
Heterodinuclear uranyl/group 14 complexes of the aryl- and anthracenyl-linked Schiff-base macrocyclic ligands LMe and LA were synthesised by reaction of UO2(H2L) with M{N(SiMe3)2}2 (M = Ge, Sn, Pb). For complexes of the anthracenyl-linked ligand (LA) the group 14 metal sits out of the N4-donor plane by up to 0.7 Å resulting in relatively short MOUO distances which decrease down the group; howev...
The design and synthesis of new heterodinuclear DNA-targeting agents are described. The abilities of cisplatin and Cu(3-Clip-Phen) [Cu(1-(1,10-phenanthrolin-3-yloxy)-3-(1,10-phenanthrolin-8-yloxy)propan-2-amine)Cl2], an artificial DNA-cleaving agent, have been combined through their "covalent coupling". This strategy has led to bifunctional complexes that are able to cleave the DNA in a double-...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
