Effective synthesis of novel O-acetylated compounds over ZrO2-Al2O3 solid acid

The solid acids such as ZrO2, Al2O3 and ZrO2-Al2O3 containing different ZrO2 loadings (10-80 mol%) were prepared by solution combustion method (SCM) and characterized for their total surface acidity by NH3-TPD/n-butylamine back titration method and crystallinity by powder X-ray diffraction (PXRD) technique. These solid acids were evaluated for their catalytic activity in the synthesis of novel O-acetylated products from substituted phenols, pyridine alcohols and aryl alcohols with acetic anhydride (AA) as an acetylating agent. The reaction conditions were optimized by varying the catalyst, molar ratio of the reactants, reaction temperature and amount of the catalyst. All the solid acids used in this study exhibited good catalytic activity in the reaction. In particular, ZrO2-Al2O3 containing 80 mol% of ZrO2 was found to be highly active in the acetylation reaction with high yield of acetylated products. Triangular correlation between the surface acidity, crystallinity and catalytic activity of solid acids was observed. These solid acids were found to be reactivable and reusable.

Low-temperature hydrogen production from methanol over a ruthenium catalyst in water

Traditionally, methanol reforming at a very high temperature (>200 degrees C) has been explored for hydrogen production. Here, we show that in situ generated ruthenium nanoparticles (ca. 1.5 nm) from an organometallic precursor promote hydrogen production from methanol in water at low temperature (90-130 degrees C), which leads to a practical and efficient approach for low-temperature hydrogen production from methanol in water. The reactivity of ruthenium nanoparticles is tuned to achieve a high rate of hydrogen gas production from methanol. Notably, the use of a pyridine-2-ol ligand significantly accelerated the hydrogen production rate by 80% to 49 mol H-2 per mol Ru per hour at 130 degrees C. Moreover, the studied ruthenium catalyst exhibits appreciably long-term stability to achieve a turnover number of 762 mol H-2 per mol Ru generating 186 L of H-2 per gram of Ru.

Synthesis of Anthranilic Diamide Derivatives Containing Moieties of Trifluoromethylpyridine and Hydrazone as Potential Anti-Viral Agents for Plants

A series of novel anthranilic diamide derivatives (5a-5ab) containing moieties of trifluoromethylpyridine and hydrazone was designed and synthesized. The synthesized compounds were evaluated in vivo for their activities against tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV). Most of the synthesized compounds displayed good to excellent antiviral activities. The compounds 5i, 5k, 5s, 5w, 5x, and 5z had the curative activity over 65% against TMV at the concentration of 500 mu g/mL, which were significantly higher than those of ningnanmycin (55.0%) and ribavirin (37.9%). Notably, the curative activity of compound Si was up to 79.5%, with the EC50 value of 75.9 mu g/mL, whereas the EC50 value of ningnanmycin was 362.4 mu g/mL. The pot experiments also further demonstrated the significantly curative effect of Si. Meanwhile, compounds 5h, 5p and Sx displayed more protective activities on TMV than that of ningnanmycin. Moreover, compounds 5a, 5e, 5f, and 5i showed inactivation activity similar to ningnanmycin at 500 mu g/mL, and the EC50 value of Se (41.5 mu g/mL) was lower than ningnanmycin (50.0 mu g/mL). The findings of transmission electron microscopic (TEM) indicated that the synthesized compounds exhibited strong and significant binding affinity to TMV coat protein (CP) and could obstruct the self-assembly and increment of TMV particles. Microscale thermophoresis (MST) studies on TMV-CP and CMV CP revealed that some of the active compounds, particularly 5i, exhibited a strong binding capability to TMV-CP or CMV-CP. This study revealed that anthranilic diamide derivatives containing moieties of trifluoromethylpyridine and hydrazone could be used as novel antiviral agents for controlling the plant viruses.

Synthesis of new azaindeno-acetonitrile derivative with inotropic activity against heart failure model

Several steroid derivatives have prepared as inotropic drugs; however, there are few reports on azaindeno-steroid derivatives with inotropic activity. The objective of this investigation was to prepare some azaindeno-acetonitrile derivatives (compounds 3 to 7) to evaluate their biological activity on left ventricular pressure. The first step was achieved by preparation of azaindeno-steroid derivatives using reactions of etherification and addition. The second stage involves the evaluation of biological activity from azaindeno-steroidderivatives on left ventricular pressure in a heart failure model using either estrone or an enone-steroid derivative (compound 2) as controls. The results showed that only compound 6 increases left ventricular pressure compared with estrone, compounds 2-5 and 6. Inconclusion, the positive inotropic effect exerted by compound 6 depends on the functional groups involved in its chemical structure.

Synthesis and Enzyme Inhibitory Activity of Novel Pyridine-2,6-dicarboxamides Bearing Primary Sulfonamide Groups

New pyridine-2,6-dicarboxamide derivatives containing sulfonamide groups were synthesized by the coupling of pyridine-2,6-dicarbonyl dichloride and various aminobenzenesulfonamides in a mixture of dichloromethane and acetone. The pyridinedicarboxamide-based sulfonamides were evaluated as carbonic anhydrase (CA) and cholinesterase (ChE) inhibitors, and they showed IC50 values in the ranges 12.8-37.6 nM against human carbonic anhydrase I (hCA I), 17.8-46.7 nM against human carbonic anhydrase II (hCA II), 98.4-197.5 nM against acetylcholinesterase (AChE), and 82.2-172.7 nM against butyrylcholinesterase (BuChE). These results are comparable with those for known inhibitors such as acetazolamide (IC50 = 32.1 nM for hCA I and IC50 = 51.0 nM for hCA II) and rivastigmine (IC50 = 60.2 nM for AChE and IC50 = 14.0 nM for BuChE), which qualifies the synthesized compounds as candidates for a more in-depth study.

Catalytic ozonation of an azo-dye using a natural aluminosilicate

Catalytic ozonation of Orange II (100 mg/L) was studied using aluminosilicate Montanit300 (R) (M) modified with H2SO4 (MS) and HCl (MH). Characterization of these samples was performed through several techniques: SEM/ EDX, FTIR, XRD, FRX, TPD pyridine, surface area, pHPZC. Acid treatment increased surface area, Si:Al ratio and quantity of acid sites, but reduced pHPZC and Fe and Mn content. Ozonation experiments achieved complete decoloration and remarkable TOC conversions of 66, 65, 88 and 91 % by single ozonation and catalytic ozonation with MH, MS and M, respectively. Higher M and MS activity under acidic pH was attributed to Mn leaching. Decreased mineralization efficiency in the presence of tertbutanol suggested a radical mechanism. At neutral pH, M showed no activity, while MS presented mild activity owing to its enlarged hydrophobicity. The M sample sustained mineralization levels over 20 h. Lower O-3 dose caused quick MS deactivation. However, it was reversed through calcination and prevented with a higher oxidant dose. Mn is naturally found in Montanit300 (R), thus making it an inexpensive catalyst. The development of a dynamic cycle combining reduced and oxidized forms of Mn was key to the outstanding activity observed.

Competing Hydrogen Bonding Interaction Creates Hierarchically Ordered Self-Assembled Structures of PMMA-b-P4VP/PVPh-b-PS Mixtures

In this study, poly(methyl methacrylate-b-4-vinylpyridine) (PMMA-b-P4VP) and poly(vinylphenol-bstyrene) (PVPh-b-PS) block copolymers were synthesized through anionic living polymerization; together, they featured one hydrogen bonded donor segment (PVPh) and two hydrogen bonded acceptors (PMMA and P4VP). Initially we investigated diblock copolymer/homopolymer blends of PMMA-b-P4VP/PVPh blends, where PVPh homopolymer (C) could act as the common solvent for PMMA-b-P4VP (Ab-B) copolymer. Short range ordered of self-assembled structure formed for pure PMMA-b-P4VP copolymer and for its blends with PVPh at lower concentrations; at higher PVPh concentrations, however, miscible disordered structures formed because of OH units of PVPh both interacted with P4VP and PMMA segments. In addition, blending the immiscible PMMA-b-P4VP into the PVPh-b-PS diblock copolymer resulted in full morphological transitions: from the lamellae, double gyroid, cylinder, sphere, and, finally, to disordered structures. Therefore, the AK effects for competitive hydrogen bonding among PVPh/PMMA and PVPh/P4VP binary pairs, these PMMA-b-P4VP/PVPh-b-PS blends exhibited several hierarchical nanostructures, including core/shell (coaxial) cylinder, cylinder-in-lamellae, and core/shell double-gyroid structures.

Hierarchical nanostructures of a liquid crystalline block copolymer with a hydrogen-bonded calamitic mesogen

With a pyridine derivative containing a calamitic mesogen 4-((6-((4′-((4-hexylphenyl)ethynyl)-[1,1′-biphenyl]-4-yl)oxy)hexyl)oxy)pyridine (HEBC6) used as the hydrogen-bonding acceptor and polydimethylsiloxane-b-poly (2,5-bis(4-carboxy phenyl)styrene) (PDMS-b-PM3H) as the hydrogen-bonding donor, a series of supramolecular liquid crystalline block copolymers (SLCBCPs) were prepared through hydrogen bonding. In the supramolecular block, the calamitic mesogen was decoupled from the motion of PM3H chains by using a flexible spacer. Different microphase-separated nanostructures and liquid crystalline (LC) structures were obtained by varying the degree of polymerization of the PM3H block and the molar ratio of HEBC6 to PDMS-b-PM3H. The SLCBCPs can self-assemble into hexagonally packed cylinders (HEX), lamellae (LAM), and inverted HEX. Smectic A phase and parallel packing of the calamitic mesogens were also observed on a smaller length scale, and these two ordered structures are synergistic and promotional. Therefore, hierarchically ordered structures can be obtained from these SLCBCPs.
