This paper includes synthesis and characterization of mixed ligand complexes derived from mefenamic acid and metformin using transition metal ions such as Co(II) and Cu(II). These complexes have been characterized by magnetic susceptibility, molar conductance, TG analyses, and spectral techniques such as FTIR and UV spectra. The theoretical study of the ligands and their complexes using semiempirical (PM6) method was used to measure IR and UV spectroscopy, HOMO-LUMO categories of the ligands. These synthesized complexes are also studied for their biological activities. The studies made on these complexes proposed a six octahedral geometry.
In this research work, the nanoparticles of aluminum oxide were synthesized by two ways. The first way is the biological by using (Pseudomonas aeruginosa) bacteria with a rate diameter (102.35) nm. The second way is the electrochemical with a rate diameter (62) nm. These nanoparticles were characterized by Atomic Force Microscopy (AFM), X-Ray diffraction technique (XRD), Transmission Electron Microscopy (TEM) and Scanninig Electron Microscopy (SEM). Alumina nanoparticles are thermodynamically stable particles over a wide temperature range . The biological activity of these nanoparticles toward different species of pathogenic bacteria (Staphylococcus aureus ) and (Pseudo monas) has been investigated. The results stated that the nanoparticles prepared by chemical way was more effective on the inhibition of bacteria than the nanoparticles prepared by biological way
In this work the photo degradation of glibinclamide is studied by UV light and different concentrations using solvents (water and ethanol) and different times. The reaction kinetic is studied and found that the photo degradation reaction of glibinclamide is (first-order) reaction and the thermodynamic properties (ΔHo, ΔSo and ΔGo) for glibinclamide were calculated and it was found to be (endothermic and spontaneous reaction).
In this paper, the computational chemistry and its importance in diagnosing of compounds, their physical properties, approaches of computational chemistry such as (molecular modeling, molecular docking and quantitative structure-activity relationships) and their applications in medicine and pharmacy were discussed and their importance in the diagnosis of pharmaceuticals and the discovery of drugs in the world of medicine and pharmacy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
