Synthesis, spectroscopic characterization, molecular docking, and ADMET studies of mannopyranoside esters as antimicrobial agents

Regioselective unimolar one-step hexanoylation of methyl alpha-D-mannopyranoside (MDM) under controlled conditions furnished the 6-O-hexanoate and indicated the regioselectivity at C-6 position. To develop mannopyranoside based potential antimicrobial sugar esters (SEs), 6-O-hexanoate was further converted into five newer 2,3,4-tri-O-acyl esters reasonably in good yields. Both prediction of activity spectra for substances (PASS) and in vitro antimicrobial evaluation established these SEs as better antifungal agents than as antibacterials. Quantum chemical study has been performed to calculate the thermodynamic, molecular orbital and electrostatic potential properties. Molecular docking and nonbonding interactions have been performed against lanosterol 14 alpha-demethylase (CYP51A1), A. flavus (1R51), and E. coli (4XO8) to search the binding affinity and interactions of MDM esters with the receptor proteins. ADMET prediction also performed to evaluate the absorption, metabolism, and toxic properties of SEs. Structure activity relationship (SAR) study along with in vitro, and in silico results indicated that amongst the acyl chains, caproic chain (C6) in combination with acetic (C2), caprylic (C8) or lauric (C12) chains were found the most promising against fungal pathogens.

Dominant Factor of Bond-Exchange Rate for Catalyst-Free Polyester Vitrimers with Internal Tertiary Amine Moieties

Catalyst-free vitrimers have attracted attention for practical application of the vitrimer concept, which requires fundamental knowledge of physical property tuning. We prepared catalyst-free vitrimers by cross-linking amorphous polyesters bearing COOH side groups with tetraepoxy compounds bearing tertiary amines (4,4′-methylenebis(N,N-diglycidylaniline), abbreviated as Mb-epoxy). The obtained network possessed ester and OH groups, and the amino moieties worked as internal catalysts for trans-esterification-based bond exchange. The competing effect of cross-link density and concentration of amines was investigated for samples with different fractions of Mbepoxy, revealing that cross-link density, which governs chain mobility, was the dominant factor in the determination of bond-exchange rate.

Chiral Rhodium Nanoparticle-Catalyzed Asymmetric Arylation Reactions

The development of heterogeneous catalyst systems for enantioselective reactions is an important subject in modern chemistry as they can be easily separated from products and potentially reused; this is particularly favorable in achieving a more sustainable society. Whereas numerous homogeneous chiral small molecule catalysts have been developed to date, there are only limited examples of heterogeneous ones that maintain high activity and have a long lifetime. On the other hand, metal nanoparticle catalysts have attracted much attention in organic chemistry due to their robustness and ease of deposition on solid supports. Given these advantages, metal nanoparticles modified with chiral ligands, defined as chiral metal nanoparticles, would work efficiently in asymmetric catalysis. Although asymmetric hydrogenation catalyzed by chiral metal nanoparticles was pioneered in the late twentieth century, the application of chiral metal nanoparticle catalysis for asymmetric C-C bond-forming reactions that give a high level of enantioselectivity with wide substrate scope was very limited. This Account summarizes recent investigations that we have carried out in the field of chiral rhodium (Rh) nanoparticle catalysis for asymmetric arylation reactions. We initially utilized composites of polystyrene-based copolymers with cross-linking moieties and carbon black incarcerated Rh nanoparticle catalysts for the asymmetric 1,4-addition of arylboronic acids to enones. We found that chiral diene-modified heterogeneous Rh nanoparticles were effective in these reactions, with excellent enantioselectivities and without causing metal leaching, and that bimetallic Rh/Ag nanoparticle catalysts enhanced activity. The catalyst could be easily recovered and reused more than ten times, thus demonstrating the robustness of metal nanoparticle catalysts. We then developed a secondary amide-substituted chiral diene modifier designed as a bifunctional ligand that possesses a metal biding site and a NH group to activate a substrate through hydrogen bonding. This chiral diene was very effective for the Rh/Ag nanoparticle-catalyzed asymmetric arylation of various electron-deficient olefins, including enones, unsaturated esters, unsaturated amides and nitroolefins, and imines to afford the corresponding products in excellent yields and with outstanding enantioselectivities. The system was also applicable for the synthesis of intermediates of various useful compounds. Furthermore, the compatibility of chiral Rh nanoparticles with other catalysts was confirmed, enabling the development of tandem reaction systems and cooperative catalyst systems. The nature of the active species was investigated. Several characteristic features of the heterogeneous nanoparticle systems that were completely different from those of the corresponding homogeneous metal complex systems were found.

How olive washing and storage affect fruit ethanol and virgin olive oil ethanol, ethyl esters and composition

BACKGROUND Olives are stored for a short time after harvesting pending processing in the oil mills. Furthermore, olives are often washed prior to fruit storage. In this work we study how washing and storage affect fruit ethanol content and the effect on virgin olive oil ethanol content and quality. RESULTS Olive storage produced an increase in the fruit ethanol content, achieving values six times higher when storage was in silos. Washing the olives resulted in an increase in fruit ethanol content, although when washed olives were processed immediately no difference was found. The increase in fruit ethanol content during storage was reflected in higher oil ethanol concentration. Similarly, olive washing resulted in oils with higher ethanol concentration. Industrial conditions gave more important increases in oil ethanol content than that from olives processed by hand. For quality parameters all the olive oils were classified as ‘extra virgin’. In general, oils showed a slight decrease in some sensory attributes. At industrial scale after 24 h storage oils were classified as ‘virgin’ because sensory defects were found. CONCLUSION Olive storage should be avoided or reduced to less than 12 h; if possible, olives should not be washed before storage since this practice favors losses in sensory characteristics and the synthesis of ethanol, a precursor of ethyl esters.

Selective Butyrate Esterase Probe for the Rapid Colorimetric and Fluorogenic Identification of Moraxella catarrhalis

Clinical identification of the pathogenic bacterium Moraxella catarrhalis in cultures relies on the detection of bacterial butyrate esterase (C4-esterase) using a coumarin-based fluorogenic substrate, 4-methylumbelliferyl butyrate. However, this classical probe may give false-positive responses because of its poor stability and lack of specificity. Here, we report a new colorimetric and fluorogenic probe design employing a meso-ester- substituted boron dipyrromethene (BODIPY) dye for the specific detection of C4-esterase activity expressed by M. catarrhalis. This new probe has resistance to nonspecific hydrolysis that is far superior to the classical probe and also selectively responds to esterase with rapid colorimetric and fluorescence signal changes and large turn-on ratios. The probe was successfully applied to the specific detection of M. catarrhalis with high sensitivity.

A Flexible and Self-Healable Gelled Polymer Electrolyte Based on a Dynamically Cross-Linked PVA Ionogel for High-Performance Supercapacitors

Ionogels combine the virtues of polymers and ionic liquids (ILs) and have greater potential for supercapacitors (SCs) than hydrogels and organic gels. Undoubtedly, the self-healing ability of ionogels dramatically improves the reliability of related SCs. Herein, we reported a dynamic diol-borate ester-cross-linked polyvinyl alcohol (PVA) ionogel electrolyte for smart double-layer capacitors. The results indicated that 1-ethyl-3-methylimidazolium chloride (EmimCl) could form a strong interaction with the hydroxy groups on PVA, thereby depressing the crystallization efficiently. The resultant ionogel exhibited an amorphous nature with excellent ionic conductivity up to 2.43 x 10(-3) S/cm, high flexibility, and 95% healing efficiency when the IL content was 90 vol %. It could be inferred from the fact that EmimCl acted not only as an ion provider to improve the ionic conductivity but also as a plasticizer to enhance the chain mobility and self-healing efficiency. Based on the unique properties of PVA-boric acid/EmimCl ionogels, a flexible and self-healable SC was assembled. The as-prepared SC delivered a specific capacitance of 90 F/g at 0.1 A/g and retained 98% capacitance after 3000 charge-discharge cycles at a current density of 2 A/g. More interestingly, it could tolerate physical bending and healing without significant performance deterioration. The present study provides a novel strategy to prepare self-healable ionogel electrolytes that can be applied to smart energy storage devices.

Relationships between the bacterial diversity and metabolites of a Chinese fermented pork product, sour meat

The present study evaluated the relationship between the bacterial diversity and metabolites of various sour meats, a traditional fermented meat product. The results showed that sour meats had a low pH (average of 4.34), low water activity (a(w), an average of 0.917), and high lactic acid (similar to 19 177.48 mg kg(-1)) and free amino acid (FAA) (similar to 4047.65 mg kg(-1)) concentrations. The lactic acid bacteria (LAB), especially Lactobacillus and Weissella, were predominated in the samples. The alcohols, aldehydes and esters accounted for the major components of volatile organic compounds (VOCs). Of which, (E)-2-octenal, nerol, cis-4-decenal, tetradecanal, linalyl acetate, linalool, 1-octen-3-ol, hexanal, 1-heptanol, benzaldehyde and (E)-2-decenal were considered as the key VOCs of sour meats. The redundancy analysis (RDA) and Pearson’s correlation analysis revealed that LAB (Lactobacillus and Weissella) and salt were positively correlated with most FAAs and VOCs. Overall, higher salinity, lower a(w) and abundant LAB might be the indicators of good sour meat quality.

Synthesis of ethyl acetate from glucose by Kluyveromyces marxianus, Cyberlindnera jadinii and Wickerhamomyces anomalus depending on the induction mode

Ethyl acetate is currently produced from fossil carbon resources. This ester could also be microbially synthesized from sugar-rich wastes of the food industry. Wild-type strains with GRAS status are preferred for such applications. Production of ethyl acetate by wild-type yeasts has been repeatedly reported, but comparative studies with several strains at various induction modes are largely missing. Here, synthesis of ethyl acetate by three yeasts with GRAS status, Kluyveromyces marxianus DSM 5422, Cyberlindnera jadinii DSM 2361 and Wickerhamomyces anomalus DSM 6766, was studied under identical and well-defined conditions in an aerated bioreactor, by inducing the ester synthesis via iron or oxygen limitation. Balancing the ester synthesis was based on measured concentrations of ethyl acetate in the exhaust gas, delivering masses of synthesized ester and synthesis rates in a high temporal resolution. All tested yeasts synthesized ethyl acetate under these conditions, but the intensity varied with the strain and induction mode. The highest yields were achieved under iron limitation with K. marxianus (0.182 g g(-1)) and under oxygen limitation with W. anomalus (0.053 g g(-1)). Iron limitation proved to be the better inducer for ester synthesis while oxygen limitation favored ethanol formation. K. marxianus DSM 5422 was the most potent producer of ethyl acetate exhibiting the highest biomass-specific synthesis rate of 0.5 g g(-1)h(-1) under moderate iron limitation.

Selective Construction of C-C and C=C Bonds by Manganese Catalyzed Coupling of Alcohols with Phosphorus Ylides

Herein, we report the manganese catalyzed coupling of alcohols with phosphorus ylides. The selectivity in the coupling of primary alcohols with phosphorus ylides to form carbon-carbon single (C-C) and carbon-carbon double (C=C) bonds can be controlled by the ligands. In the conversion of more challenging secondary alcohols with phosphorus ylides the selectivity towards the formation of C-C vs. C=C bonds can be controlled by the reaction conditions, namely the amount of base. The scope and limitations of the coupling reactions were thoroughly evaluated by the conversion of 21 alcohols and 15 ylides. Notably, compared to existing methods, which are based on precious metal complexes as catalysts, the present catalytic system is based on earth abundant manganese catalysts. The reaction can also be performed in a sequential one-pot reaction generating the phosphorus ylide in situ followed manganese catalyzed C-C and C=C bond formation. Mechanistic studies suggest that the C-C bond was generated via a borrowing hydrogen pathway and the C=C bond formation followed an acceptorless dehydrogenative coupling pathway.
