Sardo, Carla published the artcileWhen Functionalization of PLA Surfaces Meets Thiol-Yne Photochemistry: Case Study with Antibacterial Polyaspartamide Derivatives, Formula: C7H16ClNO2, the publication is Biomacromolecules (2014), 15(11), 4351-4362, database is CAplus and MEDLINE.

In this work we wish to report on the covalent functionalization of polylactide (PLA) surfaces by photoradical thiol-yne to yield antibacterial surfaces. At first, hydrophilic and hydrophobic thiol fluorescent probes are synthesized and used to study and optimize the conditions of ligation on alkyne-PLA surfaces. In a second part, a new antibacterial polyaspartamide copolymer is covalently grafted. The covalent surface modification and the d. of surface functionalization are evaluated by SEC and XPS analyses. No degradation of PLA chains is observed, whereas covalent grafting is confirmed by the presence of S2p and N1s signals. Antiadherence and antibiofilm activities are assessed against four bacterial strains, including Gram-neg. and Gram-pos. bacteria. A strong activity is observed with adherence reduction factors superior to 99.98% and biofilm formation decreased by 80%. Finally, in vitro cytocompatibility tests of the antibacterial surfaces are performed with L929 murine fibroblasts and show cell viability without promoting proliferation.

The unique reactivity of sulfoxonium ylides as a carbene source is described for a variety of X-H bond insertions, taking advantage of a simple, com. available iridium catalyst. This method has applications in both intra- and intermol. reactivity, including a practical ring-expansion strategy for lactams. The safety and stability of sulfoxonium ylides recommend them as preferable surrogates to traditional diazo ketones and esters.

The stereoselective aziridination of a range of cyclic allylic alcs. using two different chloramine salts (4-MeC₆H₄SO₂NClNa, TsNClNa and Me₃CSO₂NClNa, BusNClNa) has been explored. The stereoselectivity of these reactions was highly dependent on the structure of the allylic alc. and the chloramine salt. Generally, mixtures of cis- and trans-hydroxy aziridines were obtained, in which the major diastereomer was the cis-hydroxy aziridine, while complete cis-diastereoselectivity was observed in the aziridination of 1,3-disubstituted allylic alcs. In each case studied, aziridination using BusNClNa gave higher cis-stereoselectivity than that observed for the same reaction using TsNClNa. Unexpectedly, application of the aziridination conditions to 1-substituted cyclopent-2-en-1-ols did not generate the aziridines. Instead, epoxy sulfonamides were obtained.

The possibility of one-step creating of pH-sensitive mesostructured silica-based nanocontainers with exceptionally high payload using associates of two antiseptics (including hydrolyzable one) as templates is demonstrated. The effects of the template nature and the conditions of the sol-gel process on the porous structure of silica nanocontainers are studied and discussed. The kinetics of the templating drug release from such containers is studied and some features of this process are analyzed. It is shown that the drug release rate can be tuned by varying the medium pH. The bactericidal activity of two encapsulated antiseptics against the Staphylococcus aureus is evaluated in vitro by agar diffusion method with replacement of agar with agarose. The diameters of the inhibition zones for silica-based containers loaded with antiseptics increased with the pre-diffusion time at 4°C. At the same time, empty containers (after elimination of antiseptics by etching) did not reveal any bactericidal properties.

Jana, Gopal Chandra published the artcileDeciphering the positional impact of chlorine in a new series of berberine analogues towards the superb-selective “turn-on” hydrophobic signaling of bovine serum albumin at physiological pH, Formula: C7H6Cl2, the publication is New Journal of Chemistry (2020), 44(5), 1761-1771, database is CAplus.

The optical signals of serum albumin (SA) provide precious information for realizing its native functions, in addition to developing related biomedical applications. Herein, we report a new class of easy synthesizable and water-soluble compounds (BZ₁-BZ₅) based on different chlorine positions on 9-O-benzyl-substituted berberine scaffolds for the selective detection of bovine serum albumin (BSA) in CP buffer solution (10 mM, pH 7.2) based on two competing factors: hydrophobic interactions and steric repulsion. The frail emission intensities of these probes were enhanced upon the addition of BSA; exceptionally, a remarkable increase in emission intensity (140-fold) and remarkable lifetime and quantum yield increases make BZ₄ an excellent fluorescence turn-on hydrophobic BSA sensor. Selectivity and co-existence studies involving other proteins, free tryptophan, etc. revealed that the microenvironment around the tryptophan moiety in BSA incites drastic spectral changes upon the introduction of BSA. Moreover, the most efficient lumino-probe, BZ₄, can detect bovine serum albumin at a nanomolar level (LOD = 3.3 nM) with a broadened range of linearity and slight altering of the secondary structure of the protein. Our exptl. results and docking simulation studies show that the probe BZ₄ binds preferentially at “binding site II” of BSA. In addition, the binding and conformational alterations of BSA provoked by these analogs have been intensely investigated, and we fruitfully relate the binding results to the sensing outcome. The obtained results reveal how the different positioning of chlorine in benzyl-substituted berberine affects the hydrophobic sensing of BSA, making these probes a new category of BSA selective material with potential applications in proteome research.
