A one-pot, Hantzsch ester-mediated Knoevenagel condensation-reduction reaction has been developed for alkylation of a wide range of substituted 2,4-quinoline diols and 2,4-pyridine diols with aldehydes. The process is operationally simple to perform, scalable, and provides highly useful C-3 alkylated quinoline and pyridine diols in yields of 58-92%. The alkylation products can be converted to 2,4-dihaloquinoline and pyridine substrates for further functionalization.

A simple gram-scale method for the preparation of esters and dialkylamides of 2-(fluoro/iodo)-2H -azirine-2-carboxylic acids via the halogen exchange (Halex) reaction of 2-bromo-substituted analogues is reported. The method operates with inexpensive and safe reagents-, Bu4NF and potassium iodide, providing high product yields. Alternatively, 2-fluoro-2H-azirine-2-carboxylates can be prepared from 2-iodo- and 2-chloro-analogues. The latter compounds can be obtained in practically quantitative yield by treating the 2-iodo- and 2-bromo-2H-azirine-2-carboxylic esters with Bu4NCl.

The first catalytic procedure for the electrophilic nitration of phenols was developed using iodosylbenzene as an organocatalyst based on iodine(III) and aluminum nitrate as a nitro group source. This atom-economic protocol occurs under mild, non-Bronsted acidic and open-flask reaction conditions with a broad functional-group tolerance including several heterocycles. Density functional theory (DFT) calculations at the (SMD:MeCN)Mo8-HX/(LANLo8+f,6-311+G*) level indicated that the reaction proceeds through a cationic pathway that efficiently generates the NO2+ ion, which is the nitrating species under neutral conditions.

Fennel (seeds of Foeniculum vulgare Mill.) is the widely used aromatic and medicinal plant throughout the world. In this research, supercritical carbon dioxide (SC-CO2) extraction was carried out to extract the aromatic extract from F vulgare seeds under various operating conditions, and aromatic extract samples were characterized for properties such as yield and trans-anethole content. A three-level Box-Behnken design from response surface method was applied to optimize the extraction parameters such as pressure, temperature, and extraction time with an aim to obtain high yield and rich trans-anethole content. The optimum extraction conditions were found to be 177 bar, 40 degrees C and 68 min where the predicted oil yield and trans-anethole contents were found to be 3.798% and 95 mg/g, respectively. Under the optimum conditions, the experimental oil yield was 3.85%, and the content of trans-anethole was 94 mg/g. The results were very close to the values predicted by the model. At the same time, the chemical compositions of the oils from two different extraction methods, hydrodistillation and SC-CO2, were compared. The chemical constituents of oils from two different extraction methods found to be the same, and they showed slight difference in terms of the quantity of the main chemicals. Antibacterial and antioxidant effects of the oils obtained by the two extraction methods were compared, and they showed similar effects.

Liver cancer is a kind of high mortality cancer due to the difficulty of early diagnosis. It is necessary to develop the anticancer agents to treat liver cancer. Here, a novel chalcone derivative was synthesized and evaluated for anticancer activity in vitro against liver cancer cell lines (HepG2, SNU-423, SMMC7221, and SNU-398). The chalcone hybrid 9 displayed the antiproliferative effect against HepG2, SNU-423, SMMC7221 and SNU-398 cells with IC50 values of 0.9 mu M, 2.7 mu M, 6.2 mu M and 4.6 mu M, respectively. Cellular mechanisms showed that derivative 9 could obviously inhibit HepG2 cells growth and colony formation in a concentration-dependent manner. Analogue 9 inhibited the migration by regulating the expression levels of migration-releated markers and transcription factors (Snail and Slug). Tubulin polymerization inhibition assay illustrated that chalcone hybrid 9 might be a potent tubulin polymerization inhibitor. Importantly, compound 9 displayed the antitumor activity against liver cancer HepG2 cells in vivo with the low toxicity toward mice. Therefore, compound 9 as a novel tubulin polymerization inhibitor deserves further investigation to treat liver cancer.

A large number (63) of well-defined nitroxide radicals, all phenol-based TEMPO and PROXYL esters, were synthesized using different strategies based on well-established Steglich esterifications. All of these radicals can be used as spin probes (SPs) and spin labels (SLs) for electron paramagnetic resonance (EPR) spectroscopy of supramolecular systems. Depending on the nature of the functional group(s) on each SP/SL, the synthesized nitroxide radicals serve as polyphilic molecular toolbox for the EPR-spectroscopic detection and characterization of specific types of interactions, e. g. pi-pi interactions, sulfur-sulfur interactions, hydrogen bonding, electrostatic and dipole-dipole interactions, and van der Waals and hydrophobic interactions, in the presence of the selected supramolecular systems of interest (e. g. proteins, peptides). For each synthesized SP/SL the water solubility was gravimetrically determined for use in aqueous solution at pH 7.

The first regioselective phenoxysulfonylation of alkynes with sodium sulfinate and phenol catalyzed by I-2/base has been uncovered. This metal-free, one-pot alkyne difunctionalization process provides various (Z)-beta-phenoxy vinylsulfones under mild reaction conditions. A variety of terminal as well as internal alkynes and sodium sulfinates and a wide range of phenols/thiophenols and naphthols are viable in this transformation. Green protocol and wide substrate scope are the remarkable characteristics of this multicomponent procedure.

Deep eutectic solvents are a class of new generation green solvents formed from two or more components, which furnish a new homogeneous liquid phase with lower melting point than the individual components. Here, for the first time, dual role of DES as catalyst and reaction medium was studied for the synthesis of symmetric dihydropyridine derivatives from aldehyde, ethyl acetoacetate and ammonium acetate. The present article reports the suitability of six DESs for Hantzsch dihydropyridine synthesis at room temperature. Among this, DES 2 (ZrOCl2.8H(2)O and ethylene glycol at 1:2 ratio) was found to be the catalyst of choice with excellent recyclability. The role of DES in the present protocol was to activate the reactants through strong hydrogen bonding interaction and provide suitable medium for the reaction. The major advantages of DESs for the titled reaction are the easy preparation, low cost, non-volatility, biodegradability, simple catalytic process, excellent conversion and the reusability.

Cyanobacteria are model photosynthetic prokaryotic organisms often used in biotechnology to produce biofuels including alcohols. The effect of alcohols on cyanobacterial cell physiology and specifically on membrane fluidity is poorly understood. Previous research on various primary aliphatic alcohols found that alcohols with a short hydrocarbon chain (C-1-C-3) do not affect expression of genes related to membrane physical state. In addition, less water-soluble alcohols with a hydrocarbon chain longer than C-8 are found to have a reduced ability to reach cellular membranes hence do not drastically change membrane physical state or induce expression of stress-responsive genes. Therefore, hexan-1-ol (C-6) is suggested to have the most profound effect on cyanobacterial membrane physical state. Here, we studied the effects of hexan-1-ol on the cyanobacterium Synechocystis sp. PCC 6803 transcriptome. The transcriptome data obtained is compared to the previously reported analysis of gene expression induced by benzyl alcohol and butan-1-ol. The set of genes whose expression is induced after exposure to all three studied alcohols is identified. The expression under alcohol stress for several general stress response operons is analyzed, and examples of antisense interactions of RNA are investigated.
