Thirty compounds having 1-[2-(5-substituted-2-benzoxazolinone-3-yl) acetyl]-3,5-disubstitutedphenyl-2-pyrazoline structure and nine compounds having N’-(1,3-disubstitutedphenylallylidene)-2-(5-substituted- 2-benzoxazolinone-3-yl)-acetohydrazide skeleton were synthesized and evaluated as monoamine oxidase (MAO) inhibitors. All of the compounds exhibited selective MAO-A inhibitor activity in the nanomolar or low micromolar range. The results of the molecular docking for hydrazone derivatives supported the in vitro results. Five compounds, 6 (0.008 mu M, Selectivity Index (SI): 9.70 x 10(-4)), 7 (0.009 mu M, SI: 4.55 x 10(-5)), 14 (0.001 mu M, SI: 8.00 x 10(-4)), 21 (0.009 mu M, SI: 1.37 x 10(-5)), and 42 (0.010 mu M, SI: 5.40 x 10(-6)), exhibiting the highest inhibition and selectivity toward hMAO-A and nontoxic to hepatocytes were assessed for antidepressant activity as acute and subchronic in mice. All of these five compounds showed significant antidepressant activity with subchronic administration consistent with the increase in the brain serotonin levels and the compounds crossed the blood-brain barrier according to parallel artificial membrane permeation assay. Compounds 14, 21, and 42 exhibited an ex vivo MAO-A profile, which is highly consistent with the in vitro data.

Low aromaticity and a large number of oxygen-bridged bonds among the aromatic structural units of lignin make it possible to obtain chemicals directly. A novel Co/C@N catalyst with high activity towards hydrogenolysis of lignin-derived aryl ethers was synthesized according to the pyrolysis process of a predesigned ZIF-67. According to the results of characterization by powder X-ray diffraction (XRD), N-2 adsorption-desorption, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS), Co was reduced by the carbonized organic linker of ZIF-67, and N was doped into the carbon skeleton of the catalyst. The effects of holding time, temperature, and initial H-2 pressure on the catalytic performance of Co/C@N were evaluated in the selective hydrogenolysis of benzyl phenyl ether (BPE). BPE was completely converted and the selectivity of monomer reached to 98.2% under optimized reaction conditions. The C-alk-O bond in BPE was first dissociated to form toluene and phenol, and then phenol was rapidly hydrogenated to form cyclohexanol. Furthermore, the Co/C@N catalyst shows high activity for hydroprocessing and selective cleavage of other lignin-derived aryl ethers, including phenylethyl phenyl, diphenyl ether, dibenzyl ether, dinaphthalene ether, guaiacol, anisole and veratrole.

The synthesis of efficient and engineered noble metal catalysts for selective conversion of waste renewable lignin to valuable chemical building blocks is crucial for the economic viability of current biorefineries. Motivated by the water effect in promoting catalytic activity, hydrous ruthenium oxide (HRO) incorporating acidic systems (H-ZSM5, HY zeolite, gamma-Al2O3, and SiO2) were investigated for selective hydrodeoxygenation of lignin-derived phenols in the aqueous phase. The results indicated that the hydrous form (surface bonded water molecules) of ruthenium and high acidity of the support promote the hydrogenolysis activity of the as-prepared catalysts and increase the yield of alkylated cyclohexanols. Among all catalysts, HRO@Y showed the best performance and afforded the highest selectivity to cyclohexanols. Intensive catalyst characterization demonstrated that in situ metal formation, a large number of acid sites, good metal dispersion, and high adsorption capacity of HRO@Y for polar fractions were responsible for the efficient activity. Water considerably improved the selective hydrodeoxygenation activity of the catalyst by promoting hydrogenation and demethoxylation and hindering dehydration.

Cobalt ferrite is a promising material for many therapeutic applications, photo-catalysis, gas detectors, high-density data storage, etc. Optimization of process parameters has a vital role in tailoring its properties. Present work reports effect of precursor pH on the properties of cobalt ferrite nanoparticles dispersed in silica. Crystallite size shows escalation from 16 to 18.5 nm with increase in pH. Many undesired phases were observed at lower precursor pH. Lattice parameter and particle size distribution showed significant impact of pH. Silica matrix showed momentous change in its structure giving a high porosity structure at pH 9. Magnetic parameters show effects due to gamma-Fe2O3 phase and pH. Effect on catalytic properties was investigated for the synthesis of 5-(4-chlorophenyl)-1,2,4-triazolidine-3-thione. Structural and morphological changes due to change in pH were found to enhance the catalytic yield considerably. Exquisiteness of the material as a catalyst is that it is magnetically separable and can be reused successively, making it an economic and green catalyst. [GRAPHICS] .

The phytochemical studies on the aerial parts of Digitalis davisiana Heywood led to the isolation of three undescribed phenylethanoid glycosides named as digidavisoside A (5), digidavisoside B (7), and davisoside (8), along with 9 known compounds, ferruginoside B (1), isolugrandoside (2), lugrandoside (3), maxoside (4), 3 ””-O-methylmaxoside (6), trans-lamiuside E (9), digiciliside B (10), p-hydroxyacetophenone (11), and chrysoeriol (12). For the first time compound 11 was reported for Digitalis genus. The chemotaxonomical significance of these compounds in Plantaginaceae family was evaluated and 3′-O-glucosyl substituted phenylethanoid glycosides 4-8 and 10 were found to be chemotaxonomically important for the family. Cytotoxic activity of the aqueous fraction of the methanolic extract was also tested against HEp-2 (human larynx epidermoid carcinoma) and HepG2 (human hepatocellular carcinoma) cancer cell lines. The aqueous fraction showed stronger cytotoxicity on HEp-2 cells than on HepG2. Therefore, the cytotoxic activity of 1-4, 6, 7 and 9 were tested against HEp-2 and L929 (mouse fibroblast cell) cell lines. Other isolated compounds could not be tested due to their insufficient amount. The results were evaluated in the point of structure-activity relationships. IC50 values against HEp-2 cells were established in a range of 71.9-220 mu M. Maxoside (4), isolugrandoside (2) and lugrandoside (3) showed higher cytotoxicity against HEp.2 cell line than other isolated compounds.

A series of ZnCl2 complexes (compounds 1-10) with 4′-(substituted-phenyl)-2,2′:6′,2 ”-terpyridine that bears hydrogen (L-1), p-methyl (L-2), p-methoxy (L-3), p-phenyl (L-4), p-tolyl (L-5), p-hydroxyl (L-6), m-hydroxyl (L-7), o-hydroxyl (L-8), p-carboxyl (L-9), or p-methylsulfonyl (L-10) were prepared and then characterized by H-1 NMR, electrospray mass-spectra (ESI-MS), IR, elemental analysis, and single crystal X-ray diffraction. In vitro cytotoxicity assay was used to monitor the antiproliferative activities against tumor cells. Absorption spectroscopy, fluorescence titration, circular dichroism spectroscopy, and molecular modeling studied the DNA interactions. All of the compounds display interesting photoluminescent properties and different maximal emission peaks due to the difference of the substituent groups. The cell viability studies indicate that the compounds have excellent antiproliferative activity against four human carcinoma cell lines, A549, Bel-7402, MCF-7, and Eca-109, with the lowest IC50 values of 0.33 (10), 0.66 (6), 0.37 (7), and 1.05 (7) mu M, respectively. The spectrophotometric results reveal that the compounds have strong affinity binding with DNA as intercalator and induce DNA conformational transition. Molecular docking studies indicate that the binding is contributed by the pi…pi stacking and hydrogen bonds, providing an order of nucleotide sequence binding selectivity as ATGC > ATAT > GCGC. These compounds intercalate into the base pairs of the DNA of the tumor cells to affect their replication and transcription, and the process is supposed to play an important role in the anticancer mechanism.

Intermediates in aromatic amino acid biosynthesis can serve as substrates for the synthesis of bioactive compounds. In this study we used two intermediates in the shikimate pathway of Escherichia coli, chorismate and anthranilate, to synthesize three bioactive compounds: 4-hydroxycoumarin (4-HC), 2,4-dihydroxyquinoline (DHQ), and 4-hydroxy-1-methyl-2(1H)-quinolone (NMQ). We introduced genes for the synthesis of salicylic acid from chorismate to supply the substrate for 4-HC and the gene encoding N-methyltransferase for the synthesis of N-methylanthranilate from anthranilate. Polyketide synthases and coenzyme (Co)A ligases were tested to determine the optimal combination of genes for the synthesis of each compound. We also tested several constructs and identified the best one for increasing levels of endogenous substrates for chorismate, anthranilate, and malonyl-CoA. With the use of these strategies, 255.4 mg/L 4-HC, 753.7 mg/L DHQ, and 17.5 mg/L NMQwere synthesized. This work provides a basis for the synthesis of diverse coumarin and quinoline derivatives with potential medical applications.

Diabetic retinopathy (DR) is a major cause of blindness, and there is a lack of effective treatment at present. Rho-associated coiled-coil containing serine/threonine protein kinases (ROCKs) have recently been suggested as potential targets for the DR treatment. We herein report the discovery of 4H-chromen-4-one derivatives as a new class of ROCK inhibitors. Structure-activity relationship analyses led to the identification of the most active compound, 4-(dimethylamino)-N-(3-{2-[(4-oxo-4H-chromen-7-yl)oxy]acetamido}phenyl) (12j). This compound showed excellent kinase selectivity for ROCK I and ROCK II against 387 other kinases. In retinal explants, compound 12j protected retinal neurons from high glucose-induced oxidative stress and apoptosis-mediated cell death. Furthermore, 12j administration suppressed the improper proliferation of Muller cells and promoted the regression of vascular vessels in retinal explants cultured in a high glucose microenvironment. Collectively, our data suggest that 12j could be a potential lead compound for the treatment of DR, hence deserving further in-depth studies.

Fifty one hydrazone derivatives of eugenol were designed and docked with 2NSD and 2X22 (enzymes of H37Rv strain) using Schrodinger v7.4. The selective ten hydrazone derivatives (4, 5, 11, 18, 30, 34, 35, 37, 42, and 45) of eugenol were synthesized via esterification, hydrazination and treatment with different aldehydes. Synthesized compounds were characterized by IR, H-1 NMR, and LCMS data. The compounds were evaluated for their antitubercular potential against H37Rv using microplate alamar blue assay (MABA). The study revealed that all synthesized compounds were significantly active at concentration 50 and 100 mu g/ml, whereas compound 11 exhibited activity at 25 mu g/ml. Present study showed that antitubercular activity of novel hydrazone derivatives of eugenol is strongly connected with the position of the substituent on aromatic aldehyde or ketones.

Herein, we report a simple and efficient approach to synthesize a functionalized 2,18-dimethoxy-5,10,15-trioxa[9]helicene. It was synthesized from simple phenol building blocks using two subsequent reactions namely oxidative coupling and dehydrative cyclization or palladium mediated cyclization. The molecular integrity of the helical core was determined by single-crystal X-ray diffraction and NMR techniques. Its crystal structure showed the spontaneous resolution which was attributed to the conglomerate formation of the same helical isomer via C-H…O and pi…pi or H…pi interactions. Then, it was converted to racemic 2,18-dihydoxy-5,10,15-trioxa[9]helicene. Enantiomers were separated on preparative HPLC with high optical purity (>99 % ee). Based on electronic circular dichroism, the absolute configurations of dextrorotary and levorotatory antipodes were assigned as P and M, respectively. We also studied the absorption, emission and chiroptical behavior of these helical compounds in the solution state.
