Hu, Zheng;Wang, Hualin;Li, Linlin;Wang, Qian;Jiang, Suwei;Chen, Minmin;Li, Xingjiang;Jiang, Shaotong research published ã€?pH-responsive antibacterial film based polyvinyl alcohol/poly (acrylic acid) incorporated with aminoethyl-phloretin and application to pork preservationã€? the research content is summarized as follows. This study demonstrates a pH-responsive antibacterial film based on polyvinyl alc./poly (acrylic acid) incorporated with aminoethyl-phloretin (PVA/PAA-AEP) for intelligent food packaging. The thermal, mech., barrier and light transmittance properties of PVA/PAA are enhanced by PAA presence of â‰?%. The interactions between PVA and PAA were hydrogen and ester bonds. The pH-responsive characteristic is dependent on the protonation/deprotonation tendency of the carboxylic groups on PAA in acidic/alk. environment. The PVA/PAA3 is selected for the incorporation of AEP and its pH-responsive swelling follows Ritger-Peppas and Schott second-order models. The AEP is hydrogen bonded with the matrix of PVA/PAA3 and the release of AEP is pH-responsive and a rate-limiting step following the First-order model. With pH decrease, the predominant release control was gradually changing from polymer relaxation to Fick diffusion. The PVA/PAA3-AEP films demonstrate AEP content dependent antioxidant and antimicrobial activities. Furthermore, the antibacterial efficiency against Listeria monocytogenes and Staphylococcus aureus is significantly better than Escherichia coli. The target film PVA/PAA3-AEP3 can effectively prolong the shelf-life of pork (TVB-N < 25 mg/100 g) by 4 days at 25°C, suggesting its great potential in intelligent food packaging.

As a continuation of earlier work on classical cannabinoids bearing bulky side chains we report here the design, synthesis, and biol. evaluation of 3′-functionalized oxa-adamantyl cannabinoids as a novel class of cannabinergic ligands.

Intracellular Cu(II) in the human body is essential to many physiol. functions, and its disruption is connected to several diseases. Synthetic coumarin-lipoic acid (Cou-LA) conjugate-functionalized silver-nanoparticles decorated on nanopipettes (CSNs) were fabricated herein for the determination of intracellular Cu(II) via in situ dual Raman/fluorescence spectroscopy. The CSNs selectively sensed Cu(II) over other metal ions to induce enhanced Raman intensities and fluorescence quenching. The determination of Cu(II) in single HeLa cells was achieved in accordance with changes in the ratio of Raman intensities at 500 and 597 cm^-1 and fluorescence at 469 nm, which was ascribed to the capturing of Cu(II) by the CSNs. The Raman signals exhibited a good linear relationship with Cu(II) concentration from 10 to 75 μM with R² = 0.956. The calibration curve indicated a local Cu(II) concentration of âˆ?2.6 ± 8.6 μM in a single HeLa cell after pretreatment with 100 μM Cu(II) for 1 h. Cou-LA exhibited negligible cytotoxicity in both normoxic and hypoxic HeLa cells. However, a significant reduction in cell viability occurred with the Cu(II)-Cou-LA complex. This cytotoxicity was attributed to the generation of reactive oxygen species via a Cu-catalyzed Fenton-like process in tumor microenvironments and was found to be applicable to chemodynamic therapy (CDT). The system fabricated in this study represents a novel strategy for intracellular dual-mode Cu(II) detection and CDT applications in cancer research.

Hollmann, Tim;Berkhan, Gesche;Wagner, Lisa;Sung, Kwang Hoon;Kolb, Simon;Geise, Hendrik;Hahn, Frank research published �Biocatalysts from biosynthetic pathways: Enabling stereoselective, enzymatic cycloether formation on a gram scale� the research content is summarized as follows. Biosynthetic pathways of natural products contain many enzymes that contribute to the rapid assembly of mol. complexity. Enzymes that form complex structural elements with multiple stereocenters, like chiral saturated oxygen heterocycles (CSOH), are of particular interest for a synthetic application, as their use promises to significantly simplify access to these elements. Here, the biocatalytic characterization of AmbDH3, an enzyme that catalyzes intramol. oxa-Michael addition (IMOMA) is reported. This reaction essentially gives access to various types of CSOH with adjacent stereocenters, but it is not yet part of the repertoire of preparative biocatalysis. An in-depth study on the synthetic utility of AmbDH3 was performed, which made extensive use of complex synthetic precursor surrogates. The enzyme exhibited stability and broad substrate tolerance in in vitro experiments, which was in agreement with the results of mol. modeling. Its selectivity profile enabled kinetic resolution of chiral tetrahydropyrans (THPs) under control of up to four stereocenters. A systematic optimization of the reaction conditions enabled gram-scale conversions yielding preparative amounts of chiral THP. The synthetic utility of AmbDH3 was finally demonstrated by its successful application in the key step of a chemoenzymic total synthesis to the THP-containing phenylheptanoid (-)-centrolobine. These results highlight the synthetic potential of AmbDH3 and related IMOMA cyclases as a biocatalytic alternative that further develops the available chem.-synthetic IMOMA methodol.

The thermal behavior, including the cold crystallization, of alkyl-derivatized Sudan III (1-[4-(phenylazo)phenylazo]-2-naphthol), SD3-OCn, was investigated. Its structural flexibility due to the two azo groups caused the formation of plural crystal structures, which further resulted in complex cold crystallization A metastable nonflat structure and a thermodynamically stable flat structure resulted in the two sets of crystallization and melting behavior during the heating process. Further, the change in the alkyl chain length caused variations in the crystallization rate and crystallinity, thus systematically changing the cold crystallization behavior. It was proven that the high mobility of the Ph group triggered supercooling and cold crystallization and that the alkyl chain correspondingly controlled the thermal behavior.
