In this paper, the complexes of Shiff base of Methyl -6-[2-(diphenylmethylene)amino)-2-(4hydroxyphenyl)acetamido]-2,2-dimethyl-5-oxo-1-thia-4-azabicyclo[3.2.0]heptane-3-carboxylate (L) with Cobalt(II), Nickel(II), Cupper(II) and Zinc(II) have been prepared. The compounds have been characterized by different means such as FT-IR, UV-Vis, magnetic moment, elemental microanalyses (C.H.N), atomic absorption, and molar conductance. It is obvious when looking at the spectral study that the overall complexes obtained as monomeric structure as well as the metals center moieties are two-coordinated with octahedral geometry excepting Co complexes that existed as a tetrahedral geometry. Hyper Chem-8.0.7 program was employed, after calculating the heat of formation (ΔH°f ) , binding energy (ΔE b ), dipole moment( µ ), and FT-IR frequencies are carried out in gas phase, the geometric shape is suggested. The compounds have been also screened for their bioactivity to antibacterial and antifungal.
In this paper, we consider the Synthesis of a series of various 4-amino antipyrine derivatives containing 1,3-thiazinan-4-one, 1,3-oxazinan-6-one, and 1,3-oxazepin-4,7-dione in its structure. These derivatives were obtained via cycloaddition of the methenamine group in Schiff base analog of 4-amino antipyrine with 3-mercaptopropanoic acid, 3-chloropropanoic acid, maleic and citraconic anhydride, respectively. The Schiff bases were prepared in excellent yields by condensation of 4-amino antipyrine with 3-nitro- or 3-bromobenzaldehyde in n-butanol. We characterize the desired products by C.H.N.S analysis, FT-IR, and 1HNMR spectroscopy.
Titanium dioxide nanotubes were synthesized by anodizing Ti sheets in the ethylene glycol solution and were covered in Pt nanoparticles onto the surface of TiO2NTs using electrodeposition method from using five derivatives of Mannich base Pt complexes which have been used as precursor of platinum. The mean size, shape, elemental composition of the titanium dioxide nanotubes and platinum deposited on the template were evaluated by different techniques such as field emission scanning electron microscope (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction pattern (XRD), and energy dispersive X-ray (EDX) technique. From all these analyses, the TiO2NTs prepared and Ptnanoparticles deposited on it were identified. The diagnoses proved that all the Pt nanoparticles have a size less than 50 nm. The MCF-7 cancer cell lines and WRL68 normal cell lines were treated with concentration 800, 400,200,100, 50, 25, 12.5µg\ml of TiO2NTs and Pt\TiO2NTs(1) and (2) for 48hours using MTT assay.IC50 and inhibition rate were calculated. The result shows that the Pt\TiO2NTs have more inhibition effect on cancer cell lines than TiO2NTs array.
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.
