Nucleophilic aromatic substitution (SNAr) reactions can provide metal-free access to synthesize monosubstituted aromatic compounds. We developed efficient SNAr conditions for p-selective substitution of polyfluoroarenes with phenothiazine in the presence of a mild base to afford the corresponding 10-phenylphenothiazine (PTH) derivatives. The resulting polyfluoroarene-bearing PTH derivatives were subjected to a second SNAr reaction to generate highly functionalized PTH derivatives with potential applicability as photocatalysts for the reduction of carbon-halogen bonds.

Polysulfide anions are endowed with unique redox properties, attracting considerable attentions for their applications in alkali metals-sulfur batteries. However, the employment of these anionic species in redox catalysis for small molecule synthesis remains underdeveloped due to their moderate-poor electrochemical potential in the ground state, whereas some of them are characterized by photoabsorptions in visible spectral regions. Herein, we disclose the use of polysulfide anions as visible light photoredox catalysts for aryl cross-coupling reactions. The reaction design enables single-electron reduction of aryl halides upon the photoexcitation of tetrasulfide dianions (S-4(2-)). The resulting aryl radicals are engaged in (hetero)-biaryl cross-coupling, borylation, and hydrogenation in a redox catalytic regime involving S-4(center dot-) and S-4(2-)/S-3(center dot-)/S-3(2-) redox couples.

Meerwein-Ponndorf-Verley reduction (MPVr) is a sustainable route for the chemoselective transformation of alpha,beta-unsaturated aldehydes. However, tailoring ZrO2 catalysts for improved surface-active sites and maximum performance in the MPV reaction is still a challenge. Here, we synthesized mesoporous zirconia (ZrO2) and metal-doped zirconia (M_ZrO2, M = Cr, Mn, Fe, and Ni). The incorporation of metal dopants into zirconia’s crystal framework alters its physico-chemical properties such as surface area and total acidity-basicity. The prepared catalysts were evaluated in the MPVr using 2-propanol as a hydrogen donor under mild reaction conditions. The catalysts’ remarkable reactivity depends mainly on their surface mesostructure’s intrinsic properties rather than the specific surface area. Cr_ZrO2, which is stable and sustainable, presented superior activity and 100% selectivity to unsaturated alcohols. The synergistic effect between Cr and Zr species in the binary oxide facilitated the Lewis acidity-induced performance of the Cr_ZrO2 catalyst. Our work presents the first innovative application of a well-designed mesoporous Cr_ZrO2 in the green synthesis of unsaturated alcohols with exceptional reactivity.

Cancer continues to be the second leading cause of death worldwide. Discovery of novel therapeutic agents has crucial importance for improvement of our medical management capabilities. Dysregulation of the MET receptor tyrosine kinase pathway plays an important role in cancer progression, making this receptor an attractive molecular target for anticancer drug discovery. In this study, twenty-seven 3,4-dihydropyrimidin-2(1H)-one C5 amide derivatives were synthesized and their cancer cell growth inhibitory activity was examined against MCF-7, HT-29 and MOLT-4 cells and also NIH/3T3 non-cancer cells by MTT assay. The antipmliferative effect of the most potent derivatives were tested against MET-dependent EBC-1 and MKN-45, lung and gastric cancer cell lines, respectively. MET kinase inhibition was measured by a Homogenous Time Resolved Fluorescence (HTRF) Assay. The influence of the test compounds on cell cycle was examined by RNase/PI flow cytometric assay. A number of compounds exhibited considerable antiproliferative effects against breast and colon cancer and leukemia cell lines, relatively sparing non-cancer cells. Some derivatives bearing benzothiazolyl carboxamide moiety at C5 position (15, 21, 23, 31, and 37) showed the highest activities with IC50 values as low as 10.9 mu M. These compounds showed antiproliferative effects also against MET-amplified cells and dose-dependently inhibited MET kinase activity. They also induced G0/G1 cell cycle arrest at lower doses and apoptosis at higher doses. Molecular docking and dynamics simulation studies confirmed the interaction of compound 23 with the active site of the MET receptor. These findings demonstrate that 3,4-dihydropyrimidin-2(1H)-one analogues may represent promising targeted anticancer agents.

Comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC x GC-TOF-MS) was combined with conventional mono-dimensional GC-MS to differentiate Croatian virgin olive oils (VOO) according to variety and geographical origin, based on the profile of volatile aroma compounds isolated by HS-SPME. More than 1000 compounds were detected after untargeted profiling and 256 were identified or tentatively identified, providing one of the most detailed profiles of volatile aroma compounds in VOO up to date. Among them, 131 volatile compounds were significantly different across monovarietal VOOs, while 60 were found useful for the discrimination according to geographical origin. Many major lipoxygenase and minor non-lipoxygenase-generated compounds were shown to have discriminating ability with respect to both factors. Multivariate statistical analysis extracted twenty-one volatile markers with the highest discriminant power for varietal differentiation. The approach reported may have practical application in better understanding, defining, managing, and communicating the varietal or geographical typicity of monovarietal VOOs.

A new aromatic diamine, 4-(4-trifluoromethyl)phenyl-2,6-bis[4-(4-amino-2-trifluoromethylphenoxy)phenyl]pyridine, was synthesized by a modified Chichibabin reaction of 4-(4-nitro-2-trifluoromethylphenoxy)acetophenone with 4-triflouromethylbenzaldehyde, followed by catalytic reduction. A series of fluorinated pyridine-containing aromatic poly(ether imide)s (PEIs) were prepared from the diamine monomer with various aromatic dianhydrides via conventional two-step thermal imidization method. The resulting PEIs had inherent viscosities values of 0.68-0.90 dL/g, and could be cast and thermally converted into transparent, flexible, and tough polymer films. These PEIs were predominantly amorphous, had good solubility in common solvents such as NMP, DMAc and m-cresol at room temperature, and displayed excellent thermal stability with the glass transition temperatures of 258-315 degrees C, the temperatures at 5% weight loss of 550-585 degrees C, and the residue of higher than 55% at 750 degrees C in nitrogen. Moreover, the PEIs films showed outstanding mechanical properties with tensile strengths of 74.8-103.5 MPa, tensile moduli of 1.08-1.45 GPa, and elongations at break of 10.6-24.4%. These PEIs also exhibited low dielectric constants of 2.81-2.98 (1 MHz) and water uptake 0.39-0.68%, as well as high optical transparency with the UV cutoff wavelength in the 350-378 nm range and the wavelength of 80% transparency in the range of 412-510 nm.

Severe acute respiratory syndrome coronavirus (SARS-CoV-2) disease is a global rapidly spreading virus showing very high rates of complications and mortality. Till now, there is no effective specific treatment for the disease. Aloe is a rich source of isolated phytoconstituents that have an enormous range of biological activities. Since there are no available experimental techniques to examine these compounds for antiviral activity against SARS-CoV-2, we employed an in silico approach involving molecular docking, dynamics simulation, and binding free energy calculation using SARS-CoV-2 essential proteins as main protease and spike protein to identify lead compounds from Aloe that may help in novel drug discovery. Results retrieved from docking and molecular dynamics simulation suggested a number of promising inhibitors from Aloe. Root mean square deviation (RMSD) and root mean square fluctuation (RMSF) calculations indicated that compounds 132, 134, and 159 were the best scoring compounds against main protease, while compounds 115, 120, and 131 were the best scoring ones against spike glycoprotein. Compounds 120 and 131 were able to achieve significant stability and binding free energies during molecular dynamics simulation. In addition, the highest scoring compounds were investigated for their pharmacokinetic properties and drug-likeness. The Aloe compounds are promising active phytoconstituents for drug development for SARS-CoV-2.

Herein, we report an efficient protocol for the synthesis of spiro-imidazolidinone-cyclohexadienones from p-quinone methides (p-QMs) and dialkyloxy ureas under mild conditions. The strategy follows a two-step process involving an initial vinylogous conjugate addition of urea derivatives to p-QMs, followed by oxidative dearomative cyclization of open-chain product to the projected spiro-imidazolidinones. This protocol exhibits good functional group tolerance and provides a straightforward method to access spiro-imidazolidinone-cyclohexadienones. In follow-up chemistry, we have shown the debenzylation of spiroimidazolidinones to give N-hydroxycyclic ureas.
