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...

this study aims to design some dual-target anticancer candidates, capable to act as an alkylating agent as well as a thymidylate synthase (ts) inhibitor. the designed scaffold is a combination of nucleobase, amino acid and aziridine structures. the candidates are docked into ts and three dna double strand structures and evaluated based on their binding interaction energies and ligand efficienci...

Five rare earth complexeslanthanum(III),praseodymium(III),neodymium(III), samarium(III) and europium(III) have been synthesized from Schiff base ligand (N,N-bis (2-hydroxy-1-naphthylidene) acetylhydrazone). The complexes were characterized based on elemental analysis, molar conductance, ultraviolet, infrared, mass, thermogravimetric and powder X-ray diffraction studies. Infrared spectra sug...

a binuclear macrocyclic ligand containing dissimilar n(amine)2o2 and n(imine)2o2 coordination sites sharing two phenolic oxygen atoms, was prepared by cyclic condensation of dialdehyde precursor l1h2 with 1,3-diaminopropane. the ligand includes two propionitrile pendant arms on the amine nitrogen atoms. the homobimetallic complex [znl2zn(oac)]pf6 was synthesized by one step procedure. heterobim...

We have demonstrated a simple and efficient route for the synthesis of a novel imine based tridentate ligand and its Pd-complex to investigate the C-C cross-coupling reactions, that involve column chromatography purification in only one step. The catalytic activity of the newly synthesized catalyst was studied for the Suzuki, Sonogashira and, Heck cross-coupling reactions under mild conditions....
