Synthesis and molecular modeling of new benzimidazoles as glutathione S-transferase inhibitors and anticancer agents

Aim: Synthesis of novel glutathione S-transferases (GSTs) inhibitors constitutes a promising strategy in cancer treatment. Results & methodology: A new set of benzimidazoles clubbed with various heterocycles as GST inhibitors and anticancer agents were synthesized. The biological results proved the potential of the new compounds as GST inhibitors, specifically compounds 7 and 14 which produced more potency than ethacrynic acid by three- A nd tenfold, respectively. Most compounds exhibited promising cytotoxic activity against breast and colon cancer cell lines. Molecular modeling studies revealed that compounds 7 and 14 showed good binding with the amino acids of the GST protein. Conclusion: Both compounds 7 and 14 fulfilled the Lipinski’s rule of five suggesting them as new promising GST inhibitors and anticancer agents.

Gas-phase and particulate products from the atmospheric degradation of an isoxazole fungicide

The isoxazole structure is present in several pesticides. However, there is a lack of information about its degradation products after the release to the atmosphere. The main atmospheric reactions of hymexazol (5-methylisoxazol-3-ol), selected as representative model, were investigated at a large outdoor simulation chamber. The predominant products of atmospheric degradations were gaseous nitrogen derivates (nitric acid, nitrogen dioxide, nitrogen oxide, nitrous acid, and peroxyacetylnitrate), ozone, and small oxygenated compounds (formic acid, formaldehyde, and methylglyoxal). The aerosol yields were lower than 5%, and an OH rate-dependence was observed in the nucleation, particle growth, and size distribution. Also, the chemical composition of minor multi-oxygenated products was studied for OH-photo-oxidations. More than 20 products were detected in the gas or particulate phase. The most abundant were heterocyclic cleavage products with C4-chain and oxygenated moieties at positions 1 and 3, such as 3,4-dioxobutanoic acid, 3-oxobutanoic acid, and 3-oxobutanal. The suggested reaction pathway is the opening of heterocycle ring by the cleavage of N-O bond and C-N bond, releasing nitrogen oxides.

Scalable, One-Pot, Microwave-Accelerated Tandem Synthesis of Unsymmetrical Urea Derivatives

We report a facile, microwave-accelerated, one-pot tandem synthesis of unsymmetrical ureas via a Curtius rearrangement. In this method, one-pot microwave irradiation of commercially available (hetero)aromatic acids and amines in the presence of diphenylphosphoryl azide enabled extremely rapid (1-5 min) construction of an array of unsymmetrical ureas in good to excellent yields. We demonstrate the utility of our method in the efficient, gram-scale synthesis of key biologically active compounds targeting the cannabinoid 1 and alpha7 nicotinic acetylcholine receptors.

An efficient solvent-free synthesis of 3-methyl-4-nitro-5-styrylisoxazoles using solid nano-titania

Abstract: An efficient and solvent-free procedure for the synthesis of 3-methyl-4-nitro-5-styrylisoxazoles using nano-titania as solid support and recyclable catalyst is presented. This method provides clean, simple, solvent-free and useful alternative to synthesize styrylisoxazoles. The use of nano-titania provides excellent yield, leading to an easy separation and reuse of the catalyst up to four times without loss of yield. Also, the green matrices calculation shows low environment impact. The green chemistry matrices atom economy, reaction mass efficiency (RME), process mass intensity and E-factor are also calculated which show that this methodology is green and eco-friendly. The catalytic efficiency of heterogeneous TiO2 NPs was successfully demonstrated by recyclability experiment (up to 4 cycles). The sustainability of the catalyst was tested by performing recyclability experiment up to 4 cycles. Calculated turn over frequency (TOF) for each cycle indicates the protocol as sustainable. Graphical Abstract: SYNOPSIS: An efficient and solvent-free procedure for the synthesis of 3-methyl-4-nitro-5-styrylisoxazoles using nano-titania as solid support and recyclable catalyst is presented. This method provides a useful alternative to synthesize styrylisoxazoles. [Figure not available: see fulltext.].

Survey of main group compounds (hbr) at the gaussian-4 level of theory: Adiabatic ionization energies and enthalpies of formation

Gas phase adiabatic ionization energies (AIEs) and standard state (298.15. K, 1. atm) enthalpies of formation DeltafH(g) were calculated at the Gaussian-4 (G4) level of theory for a suite of 319 and 398 main group compounds, respectively, containing the elements hydrogen through bromine. National Institute of Standards and Technology (NIST) evaluated AIEs were available for comparison with 44 compounds, yielding good agreement when the significant variability among the individual experimental reports was taken into consideration. AIEs were estimated at the G4 level of theory for a further 126 main group compounds having at least one experimental datapoint in the NIST database, but not a NIST evaluated AIE, as well as 149 main group compounds without any experimental data in the NIST database. Experimental DeltafH(g) were available for comparison with 144 compounds, yielding good agreement, particularly against compounds with evaluated DeltafH(g) DeltafH(g) were estimated at the G4 level of theory for a further 254 main group compounds without any experimental data. The datasets comprise a benchmark set of theoretical data against which to assess future experimental and theoretical results.
