2-Guanidinobenzimidazole (BIG) and Imidiazole (I) ligands were utilized to synthesize Cu(II), VO(II), Ag(I), Pd(II) as mixed ligand complexes. All studied molecules characterized through various spectral, analytical computational studies find out their chemical structure. TGA was applied identify the occurrence of H2O besides mono-nuclear property isolated These complexes proved DFT study confirm coordinating site that proposed displays optimal three-dimensional structures compounds. The...
This study was planned to prepare new mixed ligand chelates derived from N‐(4,6‐dimethylpyrimidin‐2‐yl)‐3a,4,5,6,7,7a‐hexahydro‐1H‐benzimidazol‐2‐amine (BIP), and imidazole (I). They identified through CHN study, spectroscopic (NMR, FT‐IR, UV–Vis), conductivity, magnetic susceptibility, mass analysis, thermal analysis. Correlation between all results exposed that the BIP performed as a bi‐dentate NN donation locations, where co‐ligand shows N–H monodentate. The optimization for studied led...
ABSTRACT The complexes of Pd (II), VO Cu and Ni (II) with Schiff base (ABDS) derived from 2‐aminobenzothiazole 4‐(diethylamino)salicylaldehyde have been prepared. Various spectroscopic methodologies for analysis, which might include 1 H, 13 C NMR, infrared spectra (IR), ultraviolet–visible (UV–vis), magnetic values, applied to elucidate the construction these chemicals. For each complex, most suitable form has proposed as a result. chemical compound behaves bi‐dentate via NO donors into...
Ultra-small gold nanoparticles (Au-NPs) "≤ 10 nm diameters" have potent biomedical applications. Hence, the present study aimed to greenly synthesize ultra-small using Egyptian propolis extract. Different biological activities, in vivo bio-distribution and acute toxicity were assessed. Results revealed that, extract can successfully highly pure stable Au-NPs with average diameter 7.8 nm. In vitro antimicrobial antimycobacterial activities powerful effect of prepared Au-NPs. Moreover,...
A library of novel imidazole-1,2,3-triazole hybrids were designed and synthesized based on the hybrid pharmacophore approach. Therefore, copper(I)catalyzed click reaction thiopropargylated-imidazole 2 with several organoazides yielded two sets carrying different un/functionalized alkyl/aryl side chains 4a–k 6a–e. After full spectroscopic characterization using spectral techniques (IR, 1H, 13C NMR) elemental analyses, resulted adducts screened for their anticancer activity against four cancer...
In an effort to develop a potent antidiabetic drug, new quinoxaline derivative, 2-(4-((3-methyl-2-oxoquinoxalin-1(2H)-yl)methyl)-4,5-dihydro-1H-1,2,3-triazol-1-yl)-N-(p-tolyl)acetamide (MOQTA) was synthesized and characterized by XRD various spectroscopic tools (IR, 1H &13C NMR, ESI-MS). The geometric optimization of the molecule calculated with Density Functional Theory (DFT) method B3LYP 6–311++G(d,p) basis set. Frontier Molecular Orbitals (FMOs) Electrostatic Potential (MEP) surfaces...
Schiff base macromolecules have been successfully synthesized, utilizing a classical chemistry route and dielectric barrier discharge (DBD) plasma technique. The synthesis of monomeric units has accomplished through typical reactions aldehyde amine functional molecules. condensation polymerization the molecules instigated chemically, using p-toluene sulfonyl chloride in refluxed ethanol. molecular weight obtained polymers was discovered to be 524, 664 1,503,228 for 4a 4b, respectively....
Titanium oxide nanoparticles (TiO2 NPs) have been attracting numerous research studies due to their activity; however, there is a growing concern about the corresponding toxicity. Here in present study, titanium were newly synthesized using propolis extract followed by antimicrobial activity, cytotoxicity assay human cancer cell lines, and acute toxicity study. The physicochemical characterization of TiO2 NPs had average size = 57.5 nm, PdI 0.308, zeta potential −32.4 mV. Antimicrobial...
Toxoplasma gondii (T. gondii) is a highly prevalent parasite that has no gold standard treatment due to the poor action or numerous side effects. Focused sulfonamide-1,2,3-triazole hybrids 3a-c were wisely designed and synthesized via copper catalyzed 1,3-dipolar cycloaddition approach between prop-2-yn-1-alcohol 1 sulfa drug azides 2a-c. The newly click products fully characterized using different spectroscopic experiments loaded onto chitosan nanoparticles form novel nanoformulations for...
A new type of nano-adsorbent zinc-silver nanoparticles ornamented by multi-walled carbon nanotubes (Zn-Ag MWCNT) was efficiently synthesized double arc discharge using a newly designed rotating cylinder electrode. Zn-Ag MWCNT characterized different instrumental methods to get information about the sample shape, size, and crystallinity. Without irradiation, indicated significant potential for elimination against methylene blue (MB) which is dissolved in deionized water. When adsorbent...
Bacterial pneumonia is considered one of the most virulent diseases with high morbidity and mortality rates, especially in hospitalized patients. Moreover, bacterial resistance increased over last decades which limited therapy options to carbapenem antibiotics. Hence, metallo-β-lactamase-producing bacteria were deliberated as deadly ferocious infectious agents. Sulphadiazine-ZnO hybrids biological activity was explored vitro vivo against metallo-β-lactamases (MBLs) producing Klebsiella...
A successful oligomerization of ternary metal complexes, cobalt (II), nickel copper zinc chromium (III) and ferric sulfate with nitrilotriacetic acid (NTA) as a primary ligand glutamic secondary ligand, has been demonstrated. The formation oligomers arose from the presence moiety, which operates bridged bidentate that coordinates other moieties. novel exhibited octahedral structures, bonded together through moiety.
