The construction of cyclobutanes has attracted much attention because of its unique four-membered ring skeleton. Herein, we report the highly enantioselective direct vinylogous Michael reaction of beta,gamma-unsaturated pyrazole amides and nitroolefin using a squaramide catalyst. Cyclobutane derivatives were obtained by subsequent cyclization in good yields (up to 85%) with excellent enantioselectivities (up to 99% ee). Importantly, the large-scale reaction experiment confirmed the reliability of the vinylogous reaction. Furthermore, the synthetic utility of the vinylogous adducts and cyclobutane derivatives has been realized.

Two new coordination complexes of Cu(ii) viz.; [Cu(bpy)(2)(NO3)]NO3 center dot 5H(2)O (1) and [Cu(phen)(Hdmpz)Cl-2]center dot H2O (2) (bpy = 2,2 ‘-bipyridine, phen = 1,10-phenanthroline, Hdmpz = 3,5-dimethyl pyrazole) have been synthesized and characterized by single crystal X-ray diffraction, electronic spectroscopy, EPR, FT-IR spectroscopy and TGA. The nitrate anion and the water molecules in the lattice of 1 are involved in the formation of unconventional infinite supramolecular crown-like nitrate-water clusters. The unconventional enclathration of guest cationic complex moieties of 1 within the supramolecular nitrate-water crown hosts provides stability to the crystal structure. Crystal structure analysis of 2 reveals the presence of cooperative ternary pi-stacked assemblies with enclathration of single guest water molecules in hexameric Cu(II) supramolecular host cavities. Theoretical calculations have been performed to analyse the non-covalent interactions in the compounds; focusing on the unusual H-bonding network/anion-pi cooperative assemblies in 1 and two different pi-stacked cooperative assemblies in 2. DFT studies reveal that the distribution and orientation of the H-bonds in the cooperative H-bonding network in 1 is the most favoured. The high interaction energies of (pi-pi)(1) and (pi-pi)(2) in pi-stacked ternary assemblies of 2 can be attributed to the participation of the entire aromatic surfaces with antiparallel orientations and the cooperative C-H center dot center dot center dot Cl interactions respectively. The in vitro antiproliferative activities of the compounds considering cell cytotoxicity, apoptosis and DNA fragmentation assays reveal significant concentration dependent cytotoxicity in DL cancer cells with nominal effects in normal PBMC cells. The molecular docking and pharmacophore studies established the structure activity relationship of the compounds.

In the process of research and development of new drugs, in silico analyzes are widely used. They address the pharmacokinetics of the molecules in study and can predict the binding mode and affinity, using a docking software. This approach can optimize the development of new drugs, reducing costs, time, and resources. In this study, a library of 300 pyrazole-chalcone derivatives were designed, the in silico ADMET (absorption, distribution, metabolism, excretion, and toxicity) properties were evaluated, and a structure-based virtual screening was performed using AutoDock Vina. The docking results exhibited that the derivatives binding mode at the COX-2 active site is similar to celecoxib, the reference drug, and presented similar binding energy. Six compounds were synthetized and tested for in vitro inhibition of the COX-1 and COX-2 isoenzymes and the selectivity index (SI) was calculated. The compound 2a11 showed the best activity for COX-2 (IC50COX-2=0.73M) whereas the control, celecoxib, resulted IC50COX-2=0.88M. All the other compounds synthetized presented better potency for COX-2 inhibition than the control. Compound 2a23 exhibited the higher SI, of 280.17 (IC50COX-1=210.13M/ IC50COX-2=0.75M), while celecoxib was 246.88 (IC50COX-1=217.26M/ IC50COX-2=0.88M). These results corroborate with a possible anti-inflammatory activity and COX-2 selectivity of the new compounds synthetized.

Microwave-assisted pyrolysis of furfural residue (FR) in an auger reactor was conducted. The biochar yield decreased and non-condensable gas yield increased with increasing temperature. Condensate yield reached maximum (i.e. 21.49 wt%) at 550 degrees C. Kaolin, CaO and K2CO3 enhanced tar secondary reactions, reduced the yield and O/C ratio of bio-oil, improved GC-MS areas of phenolic compounds to 76.25%, 89.28% and 93.1%, respectively. All additives improved yields of H-2 and CH4, while CaO reduced CO2. With increasing temperature, relative proportion (RP) of HCN/NH3 reached up to 13.67, while RP of H2S and chlorine in volatiles increased from 1.17%, 5.97% to 2.75%, 9.00%, respectively. Ammonia nitrogen in volatiles increased to 6.94% by K2CO3. Kaolin improved RP of HCN from 0.11% to 5.47%, while K2CO3 eliminated HCN. H2S increased with kaolin addition and decreased with CaO and K2CO3. Electricity consumption of MWAP varied from 0.5 to 3.78 (kWh/kg FR) depending on temperatures and additives.

Bis(pyrazolyl)alkanes are a prolific class of ligands for catalysis, accessible by the condensation between bis(pyrazolyl)methanones and carbonyls. In this report, we describe a nucleophile-catalyzed innovation on this condensation that avoids the transition metals, high temperatures, reagent excess, and air-sensitive reagents common among the existing protocols. Significantly, this method accommodates sterically hindered and electronically diverse pyrazoles and aldehydes, applicable for systematic ligand optimization. Furthermore, our scope includes azoles and bridging functional groups previously unreported for this reaction, promising for new heteroscorpionate catalysts. We provide the first direct evidence for an elusive reaction intermediate and characterize the most complete mechanism for this condensation.

Antibacterial properties of microencapsulated Lactobacillus plantarum cell-free supernatant (CFS) in combinations with aqueous or ethanolic propolis extract at doses of 1% against fish spoilage bacteria were investigated. Microencapsulated samples contained more than 17 compounds, of which furyl alcohol, acetic acid, maltol, and 2(5H) furanon were identified as common compounds. The effects of microencapsulated CFS from L. plantarum in combination with or without propolis extracts on the fish spoilage bacteria varied according to the bacterial species. Among the fish spoilage bacteria, the highest antimicrobial activity of samples was observed against P. damselae with >15.5 mm inhibition diameter zone. Pure and microencapsulated CFS from L. plantarum showed the lowest antimicrobial effects on P. mirabilis with a corresponding inhibition diameter zone of 8.33 and 8.00 mm. Microencapsulated CFS from L. plantarum in combination with aqueous propolis extract had 25 mg/ml of MIC and 50 mg/ml of MBC on all bacteria although the bactericidal effect of microencapsulated samples in combination with ethanolic propolis extract occurred at a level of above 50 mg/ml. The study results revealed that co-microencapsulation of CFS obtained from L. plantarum with propolis extract, especially its aqueous extract, could be potentially used as antimicrobial agents to overcome microbial growth in foods.

Tetrakis(1H-pyrazol-l-yl)methanes are very rare compounds of which only two are known: the unsubstituted 1 obtained classically by Wicket in 1937 from carbon tetrachloride and prepared again several times and the 3,5-dimethyl substituted 2 obtained serendipitously by Pombeiro in 2009. We have now extended this group to include four new derivatives 8, 9,11 and 12 bearing methyl groups. The X-ray crystal structure of the four compounds has been determined. They have been studied by NMR both in solution (H-1, C-13, N-15) and in the solid state (C-13 and N-15). DFT calculations of the six compounds (geometries, energies and absolute shieldings) have been used to discuss the experimental observations. (C) 2019 Elsevier Ltd. All rights reserved.

A visible-light photoredox catalyzed C-N coupling of quinoxaline-2(1H)-ones with azoles in the absence of external photosensitizer has been developed. The protocol employs commercially available pyrazoles and triazoles as amination reagents and shows wide substrate scope, providing the corresponding C3-position amination products in good yields and high regioselectivity under ambient conditions. Investigations indicate that the starting materials and products can act as photosensitizers avoiding use of additional photocatalyst in an autocatalytic manner. In addition,(1)O(2)coexists with O(2)(.-)from molecular oxygen (O-3(2)) via an energy transfer (ET) and single electron transfer (SET) process during the reaction.
