Uniform dispersion of ultrafine spherical silver nanoparticles (NPs) was obtained over the surface of Fe3O4@SiO2@KIT-6 core-shell support via functionalization of the mesoporous KIT-6 shell by aminopropyltriethoxysilane, followed by coordination of Ag+ ions and in situ chemical reduction with sodium borohydride. The obtained hybrid material, Fe3O4@SiO2@KIT-6-Ag nanocomposite, was fully characterized by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy, and used as an efficient catalyst for selective reduction of nitroaromatic compounds in aqueous solution at ambient temperature and neutral pH [nine examples, apparent rate constants at 25 degrees C, k (min(-1)), 0.112-0.628]. As a non-aromatic example, nitrofurazone which is a cytotoxic antibiotic was also reduced selectively at nitro group without reduction of other functionalities. Fe3O4@SiO2@KIT-6-Ag NPs also showed potential ability to act as catalyst for reduction of nitromethane in aqueous solution which can provide a colorimetric method for detection of nitromethane in solution down to 0.9×10(-4)molL(-1). Fe3O4@SiO2@KIT-6-Ag nanocomposite was also screened for its antibacterial activity, and satisfactory results were obtained in comparison with drug references including Tetracycline, Chloramphenicol and Cefotaxime as positive controls, on gram negative Escherichia coli and Pseudomonas aeroginosa. Ease of recycling of the Fe3O4@SiO2@KIT-6-Ag is another benefit of this nanocatalyst. Under the optimized conditions, the recycled catalyst showed 15% loss of efficiency after five successive runs.

The present study examines the significance of various non-covalent interactions in the supramolecular assembly of (E)-1-(1-(4-nitrophenyl)ethylidene)-2-phenylhydrazine 1c and (E)-3-bromo-N’-(1-phenylethylidene)benzohydrazide 2d. The synthesized compounds were fully characterized by spectroscopic methods and single crystal X-ray diffraction analysis. The topology of the supramolecular assemblies was controlled by various non-covalent interactions including classical hydrogen bonding, C-H center dot center dot center dot pi and Br center dot center dot center dot Br interactions which were examined in detail using several theoretical methods and DFT calculations. The optimized geometric parameters of compounds 1c and 2d were calculated using density functional theory (DFT/B3LYP) quantum chemical method with the 6-311++G(d,p) basis set using the crystallographic coordinates. Additionally, fragments contributing to the HOMO and LUMO molecular orbitals were investigated at the same level of theory. The nature and various types of intermolecular interactions in the crystal structures was also investigated by Hirshfeld surface analysis. The synthesized Schiff bases were also studied for their potential as drugs and physicochemical properties. Bioevaluation against four cancer cell lines (NCI-H460, NCI-H460/Bcl-2, MDA-MB-231 and MCF-7) showed that compound 1c was a more potent inducer of toxicity compared to 2d. The putative binding modes of the bioactive Schiff bases were investigated using molecular docking tools and the results revealed that both the inhibitors were stabilized in the active pocket of the enzyme via the formation of various interactions with the key amino acid residues.

We report carbonyl-stabilized phosphorus ylides as general and efficient catalysts for the cyanosilylation of ketones. The N,N-diethylacetamide derived phosphorane is identified as an extremely efficient catalyst for the cyanosilylation of dialkyl ketones, alkyl aryl ketones, diaryl ketones, and alpha,beta-unsaturated enones with catalyst loading down to 0.005 mol %, the lowest ever known for ketone cyanosilylation. Aldehydes, aldimines, and ketimines are also viable substrates. By NMR and React IR analysis, as well as electrical conductivity experiments, it is proposed that the phosphorane acts as a Lewis base in order to mediate the reaction via the desilylative nucleophilic activation of TMSCN.

An efficient transition-metal-free protocol for the hydroboration of aldehydes and ketones (reduction) was developed. The hydroboration of a wide range of aldehydes and ketones with pinacolborane (HBpin) under the K2CO3 catalyst has been studied. The reaction system is practical and reliable and proceeds under extremely mild and operationally simple conditions. No prior preparation of the complex metal catalyst was required, and hydroboration occurred stoichiometrically. Further, the chemoselective reduction of aldehydes over ketones was carried out. Moreover, we demonstrated the use of K2CO3 as an efficient catalyst for the hydroboration of alkenes. The operational simplicity, inexpensive and transition-metal-free catalyst, and the applicability to gram-scale synthesis strengthen its potential applications for hydroboration (reduction) at an industrial scale.

An efficient continuous flow process for the synthesis of 5-substituted 1H-tetrazoles is described. The process involves the reaction between a polymer-supported triorganotin azide and organic nitriles. The polymer-supported organotin azide, which is in situ generated with a polystyrene-supported triorganotin alkoxide and trimethylsilylazide, is immobilized in a packed bed reactor. This approach is simple, fast (it takes from 7.5 to 15 min), and guarantees a low concentration of tin residues in the products (<5 ppm). The process was developed to aryl-, heteroaryl-, and also alkylnitriles and was applied for the synthesis of valsartan, an angiotensin II receptor antagonist. Safety of 2,2-Diphenylacetonitrile.

Tuberculosis (TB) causes millions of deaths every year, ranking as one of the most dangerous infectious diseases worldwide. Because several pathogenic strains of Mycobacterium tuberculosis (Mtb) have developed resistance against most of the established anti-TB drugs, new therapeutic options are urgently needed. An attractive target for the development of new antitubercular agents is the salicylate synthase MbtI, an essential enzyme for the mycobacterial siderophore biochemical machinery, absent in human cells. A set of analogues of I and II, two of the most potent MbtI inhibitors identified to date, was synthesized, characterized, and tested to elucidate the structural requirements for achieving an efficient MbtI inhibition and a potent antitubercular activity with this class of compounds. The structure-activity relationships (SAR) here discussed evidenced the importance of the furan as part of the pharmacophore and led to the preparation of six new compounds (IV-IX), which gave us the opportunity to examine a hitherto unexplored position of the phenyl ring. Among them emerged 5-(3-cyano-5-(trifluoromethyl)phenyl)furan-2-carboxylic acid (IV), endowed with comparable inhibitory properties to the previous leads, but a better antitubercular activity, which is a key issue in MbtI inhibitor research. Therefore, compound IV offers promising prospects for future studies on the development of novel agents against mycobacterial infections.

The ultraviolet (UV) absorption spectra of the supermolecular system involving silver nanoparticles-substituted N-(phenyl-ethylene)-anilines were investigated. Silver nanoparticles (AgNPs) and 77 kinds of substituted N-(phenyl-ethylene)-anilines ZArC (Me)NArY (ZPEAY, including 40 compounds 2-H-XPEAY without ortho-hydroxyl and 37 compounds 2-OH-XPEAY with ortho-hydroxyl) were prepared. The size of AgNPs was measured with transmission electron microscopy. To study the effect of substituents X and Y on the UV spectra of the supermolecular system of AgNPs-ZPEAY, the authors measured the UV absorption spectra of AgNPs, ZPEAY, and AgNPs-ZPEAY solutions. The experimental results show that (a) the size of AgNPs increases in AgNPs-ZPEAY solution compared with that in AgNPs solution, due to the absorption of ZPEAY molecules on the surface of AgNPs; (b) the UV absorption wavelength of ZPEAY changes in AgNPs-ZPEAY solution and there is a limitation for the wavelength shift (lambda (WSL)) between ZPEAY and AgNPs-ZPEAY system; (c) there is a quantitative correlation between the wavenumber Delta nu (WSL) of lambda (WSL) and the substituent constants (Hammett constant sigma and excited-state substituent constant sigma CCex) of substituents X and Y; (d) the intramolecular hydrogen bonding in 2-OH-XPEAY makes the Delta nu (WSL) a red shift in AgNPs-ZPEAY system.
