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.

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.

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.

Development and in vitro evaluation of mucoadhesive gelatin films for the vaginal delivery of econazole

Several strategies have been explored to obtain effective econazole nitrate (ECN) concentrations at the site of application for a prolonged time. In this paper, different gelatin-based film formulations for vaginal application were investigated, containing ECN (10% w/w with respect to gelatin) as pure drug or as drug-solid dispersions (SD). For the production of SD, different polymers were evaluated: polyvinylpyrmlidone (PVP), Soluplus (R) (polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol graft copolymer) and Gelucire (R) 50/13 (mixture of mono-, di- and triglycerides of fatty acids, esters of PEG 1500 and free PEG). Gelucire (R)-SD showed the best solubility enhancement, increasing 9.2 times the ECN solubility in pH 4.5 solution respect to pure drug; DSC and XRD analysis confirmed the crystalline form of the drug. XRD results evidenced that all gelatin-based films, containing either the drug or the SD, underwent the topotactic transformation of ECN into crystalline econazole (EC), owing to a strong interaction between the drug and the gelatin. Films containing Gelucire (R)-based SD displayed lower brittleness and rigidity with respect to the other samples; moreover they demonstrated good structural integrity after 24 h of incubation in the acidic solution (swelling degree of about 350%). Then, Gelucire (R)-SD based films were compared with the corresponding formulations cross-linked by genipin (2% w/w). The addition of genipin did not interfere with the drug-gelatin interaction. Gelucire (R)-SD based films showed similar release profiles to neat gelatin films, enhancing the drug release in the first 5 h and controlling the EC release over time, avoiding the use of a crosslinking additive. Finally, gelatin films containing Gelucire (R) solid dispersion displayed good adhesiveness and anti-Candida activity. Overall, results support the potential use of this film formulation as noncytotoxic EC delivery system for the treatment of vaginal candidiasis.

Experimental investigations on the feasibility of higher blends of biodiesel in variable compression ratio diesel engine

In this paper, the biodiesel prepared from non-edible Linum usitatissimum oil tested in compression ignition engine for its viability option over the petrodiesel. The present study investigated the effects of a fraction of biodiesel in the blends in the events of variation of compression ratio on performance, combustion and emission characteristics and compared with baseline fuel PD operated at rated compression ratio 17.5:1. It is reported that at CR 16, the maximum BTE improvement observed was 26.73% for LB30.The maximum gain in BSFC for LB10 was 3-12% higher. The EGT increases with load, biodiesel contents and decreases with CRs. The emission of CO, HC, and CO2 reduced with an increase in CRs except penalty in the discharge of NOx by maximum 30.8% for LB30 at CR18. Thus higher blends, i.e. LB20 and LB30 can also be used as an alternative fuel in a partially modified diesel engine i.e. at CR 18.

Crystal engineering construction of caffeic acid derivatives with potential applications in pharmaceuticals and degradable polymeric materials

Natural products are precious feedstock in drug discovery and sustainable materials. This work using crystal engineering strategy, visible light, and solvent-free cycloaddition successfully constructed two caffeic acid derivatives, rel-(1R,2R,3S,4S)-2,4-bis(3,4-dihydroxyphenyl)cyclobutane-1,3-dicarboxylate and rel-(1R,2R,3S,4S)-2,4-bis(3,4-dihydroxyphenyl)cyclobutane-1,3-dicarboxylic acid. Because of the multiple stereocenters, it is challenging to prepare those compounds using traditional organic synthesis methods. The crystal engineering Hirshfeld surface analysis and 2D intermolecular interaction fingerprints were applied to synthetic route design. The light resources used in this work was visible LED or free, clean, and renewable sunlight. The evidence suggested that pure stereoisomer was obtained demonstrating the stereospecificity and efficiency of the topochemical cycloaddition reaction. The derivatives exhibited free radical scavenging and antioxidant biological activities, as well as the potential inhibitory activity of fatty acid binding proteins. One of the derivatives is the precursor of the natural product shimobashiric acid C which paves the way for the total synthesis and further study of shimobashiric acid C. In addition, the derivatives possess photodegradability at a specific wavelength, which is very attractive for green degradable polymeric materials.

Transthyretin Amyloidogenesis Inhibitors: From Discovery to Current Developments

Transthyretin (TTR) is a homotetrameric protein in human plasma. The dissociation of the TTR tetramer and misfolding of the TTR monomer result in the formation of amyloid fibrils. Hereditary TTR amyloidosis is characterized by the extracellular deposition of amyloid fibrils containing TTR variants. The development of small molecules that kinetically stabilize the TTR tetramer is one of the effective strategies for the treatment of hereditary TTR amyloidosis. So far, several stabilizers have been discovered. Tafamidis is the only approved stabilizer for treatment of hereditary TTR amyloidosis, although two nucleic acid medicines that inhibit TTR synthesis, inotersen and patisiran, were recently approved for treatment of this disorder. In this Perspective, we seek to describe the representative kinetic stabilizers from discovery to development, interweaving the crystallographic study of the complex structures.
