Tetrapyridinesilver(I) perrhenate [Agpy4]ReO4 was synthesized, and its crystal structure Raman spectra were elucidated at low temperatures. The lattice is constructed from isolated tetrahedral cations anions having no argentophilic interactions. Weak hydrogen bonds are formed between the oxygens of disordered ortho-hydrogens pyridine ligands. No parallel ?…? stacking interactions observed, but ...

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...

a series of 3-hydroxypyridin-4-one derivatives (hpos) were synthesized and their partition coefficient values (k part ) were determined. the cytotoxic effects of these iron chelators against hela cancer cells were also evaluated. the ic 50 of hpos was determined using mtt assay. among these ligands, compound 4e (k part =5.02) with an ic 50 of 30 µm and 4f (k part =0.1) with an ic 50 of 700 µm s...

Current researches have showed that N3, N5-diaryl-2, 6-dimethyl -1, 4-dihydropyrine-3, 5- dicarboxamide analogues demonstrate notable anti-tubercular activity. In this study, Hantzsch condensation was used to design and synthesize new analogues of dihydropyridine (DHP). Different diary carboxamides were inserted at positions 3 and 5 of the DHP ring. 4(5)-chloro-2-ethyl-5(4)-imidazolyl moiety wa...

The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.
