Molecular modelling has identified a new RNA conformational feature created by the insertion of bulge residues into duplex regions that may act as a recognition site for small molecule binding, in particular for inert dinuclear ruthenium complexes.
Incorporation of fluorene groups into the salicylidene moiety significantly enhances the luminescence of a number of multinuclear alkynylated Zn(II)-salophen complexes. Preparation of these complexes was achieved by a synthetic strategy with facile handling of the reactants, simple purification of the products, and one-pot reaction process. Two synthetic methods are used for the preparation of ...
A Mechanistic Study on the Reaction of Non‐Heme Diiron(III)‐Peroxido Complexes with Benzoyl Chloride
Dinuclear iron peroxido complexes are important intermediates for selective oxidation reactions. A detailed kinetic study of the reaction benzoyl chloride (BzCl) with a dinuclear non-heme cis end-on complex ligand EtHPTB (N,N,N′,N′-tetrakis[(N-ethyl-2-benzimidazolyl)methyl]-2-hydroxy-1,3-diamino-propane) had been performed. The starting complex, can be obtained either by iron(II) O2 or instead,...
Electron transfer and delocalization of the pi systems were investigated in mono- and dinuclear Ru complexes with the zwitterionic ligand L = N,N'-diisopropyl-2-amino-5-alcoholate-1,4-benzoquinonemonoiminium.
Herein we demonstrated that dinuclear zinc complexes could overcome drug resistance in R-HepG2 drug resistance hepatocellular carcinoma cells through induction of mitochondria-mediated apoptosis or by triggering mitochondria fragmentation, depletion of the membrane potential and intracellular ATP levels.
The amine functionality of the linker on the dinuclear complex [trans-Ru(dppm)(2)(Ctbd1;CFc)(NCCH(2)CH(2)NH(2))][PF(6)] reacts with Si-Cl bonds of a chlorinated, highly B doped Si (111) surface to yield Si-N surface-complex bonds. The surface bound complex is constrained to a near vertical orientation by the chain length of the linker as confirmed by variable angle XPS. Oxidation of the dinucle...
Low-dimensional metal complexes are versatile materials with tunable physical and chemical properties that make these systems promising platforms for caloric applications. In this context, work proposes a quantum Stirling cycle based on dinuclear complex as working substance. The results show the operational modes can be managed when considering change in magnetic coupling of material temperatu...
