LaCoO3 was treated by a sub-molten salt-acid (S-A) approach to remove La cations from the solid structure. The resulting catalyst possessed disordered spinel Co3O4 structure and higher Co2+/Co3+ ratio on the surface, which induced the formation of oxygen vacancies. The new formed mesoporous mate...
Magnetic nanoparticles for applications in life sciences require their uniform dispersion in water which involves surface modification with organic hydrophylic molecules. This study was focused on cobalt doped ferrite nanoparticles known mainly for their usefulness in experimental oncologic ther...
The coordination properties of 2-picolinehydroxamic acid towards cobalt(II) in aqueous solution were determined by a pH-metric method and confirmed by spectroscopic (UV–Vis and ESI-MS) studies. The results show the formation of mononuclear complexes, as well as of metallacrowns (MC). All method...
The selective catalytic hydrogenation of carboxylic acids is an important process for alcohol production, while efficient heterogeneous catalyst systems are still being explored. Here, we report the selective hydrogenation of carboxylic acids using earth-abundant cobalt oxides through a reaction...
The purpose of this work was to investigate the electrocatalytic activity of a molecular clathrochelate, containing cobalt as active centre, for the hydrogen evolution reaction (HER) in aqueous acidic media. The electrocatalytic activity of this cobalt complex has been measured using a glassy ca...
We report that the Co/Mn oxides nanocomposite, obtained by directly pyrolying cobalt doped Mn-BTC precursor, is a new oxidase mimetic for colorimetric sensing of acid phosphatase (ACP). By tuning the molar ratios of cobalt ions to Mn-BTC (BTC = 1,3,5-benzenetricarboxylate) precursor, four bimeta...
A series of Co-based N, S dual-doped carbon catalysts were prepared successfully via the pyrolysis of porous organic polymers (POPs) impregnated with cobalt salt and characterized by TEM, XRD, XPS, etc. The successful construction of cobalt-nitrogen (Co-Nx) sites is confirmed by XPS spectra. It ...
At 100° and in 0.2 M Ba(OH)2 the Rp diastereomer of cyclic 2'-deoxyadenosine 3',5' -[17O, 18O]monophosphate is hydrolyzed to a 4:1 mixture of the Sp diastereomer of 3' -[16O, 17O, 18O]dAMP and the Rp diastereomer of 5' -[16O, 17O, 18O]dAMP, respectively, demonstrating t...
A naturally occurring compound, 2'-deoxyadenosine-3'-monophosphate (2'-deoxy-3'-AMP), is a potent inhibitor (Ki about 10 μM) of the adenylate cuclase activity of various rat tissues, toad erythrocytes, and mammalian cells in culture. This inhibition is reversible and appears...
A naturally occurring inhibitor of adenylate cyclase has been found in various rat tissues and toad erythrocytes. The compound containing this inhibitory activity has been isolated from several cell types. Physical, chemical, and enzymatic analyses define this inhibitor as 2'-deoxyadenosine...
In this work, the excited-state intermolecular hydrogen bonding interactions, photoinduced charge transfer, and vibrational spectroscopic properties of deprotonated deoxyadenosine monophosphate [dAMP-H]− anion in aqueous solution were investigated by the DFT/TDDFT method. The intermolecular hydr...
Determination of the crystal structure of bis(diethyldithiocarbamato)dibromopalladium(IV) (I), shows it to have a distorted octahedral geometry, with the bromide ligands mutually cis. We also report the structure of a new palladium(II) complex, obtained as a decomposition product in the crystall...
Eight complexes with the formula [M(NN)(DHBA)] (where MPd(II) or Pt(II), NN is 2,2′-bipyridine (BPY), 2,2′-biquinoline (BIQ), 1,10-phenanthroline (PHEN), 4,7-diphenyl-1,10-phenanthroline (DPP) and DHBA is 3,4-dihydroxybenzoic acid dianion) were found to photosensitize the oxidation of 2,...
The structure of [Pt(Et2dtc)(P2P′)]BPh4 (Et2dtcS2CNEt2 and P2P′PhP(CH2CH2PPh2)2) has been determined from three-dimensional X-ray data. Monoclinic crystals of the complex belong to the space group P21/c with cell dimensions a=18.375(2), b=15.724(2), c=20.426(3) Å, β=108.85(1)°, V=5585(3)...
Compounds 2,4-diacetylthiazole 5 and 2,5-diacetylthiazole 6, of interest for their flavour and aroma properties, have been prepared for the first time by tetrabromination and silver nitrate treatment of the corresponding diethylthiazoles.
Deep eutectic solvents (DESs) are derived from two or more salts as the hydrogen bond acceptors (HBAs) and hydrogen bond donors (HBDs). In this work, six deep eutectic solvents (DESs) were prepared namely allyltriphenyl phosphonium bromide- diethylene glycol (ATPPB-DEG) and allyltriphenyl phosph...
In mitochondrial apoptosis, the formation of cytochrome c–cardiolipin complex ([CL-cyt c]) with peroxidase properties is an early event in the cascade of reactions that leads to cell death. Herein, we report the synthesis of a new prodrug, (2-hydroxyamino-vinyl)-triphenyl-phosphonium (HVTP), wh...
The preparation of phosphonium ylides, the importance of which is obvious in different fields of chemistry including organic synthesis, medicinal chemistry, green chemistry, and materials science, was widely studied in the second half of the twentieth century. Nevertheless, the new green procedu...
Heavy metal ions (HMIs) induce sever toxic and carcinogenic aspects through many mechanisms, which are not still understood. Therefore, the aim of this paper is to explorer new simple and efficient HMIs scavenger. In this endeavor, we have successfully fabricated a new aminothiazolyl-functionali...
Chitosan (CS) has been widely recognized as an important biomaterial due to its good antimicrobial activity, biocompatibility and biodegradability. However, CS is insoluble in water in neutral and alkaline aqueous solution due to the linear aggregation of chain molecules and the formation of cry...
