Merchant, Jaysukhlal R. published the artcileSynthesis of sulfones with antitubercular activity, Application of Coumarin-6-sulfonyl chloride, the publication is Chemistry & Industry (London, United Kingdom) (1982), 955, database is CAplus.

6-Coumarylsulfonyl chlorides underwent Friedel-Crafts reaction with aromatic compounds to give 6-coumaryl aryl sulfones in 30-40% yield. E.g., treatment of sulfonyl chloride I (R = Cl) with PhEt for 4 h at 100° in the presence of AlCl₃ gave I (R = C₆H₄Et-p) (II). The sulfones were generally active against Mycobacterium tuberculosis.

Ogris, Manfred published the artcileNovel biocompatible cationic copolymers based on polyaspartylhydrazide being potent as gene vector on tumor cells, COA of Formula: C7H16ClNO2, the publication is Pharmaceutical Research (2007), 24(12), 2213-2222, database is CAplus and MEDLINE.

The reaction between α,β-poly(aspartylhydrazide) (PAHy), a water soluble synthetic polymer and 3-(carboxypropyl)trimethyl-ammonium chloride (CPTACl) produced copolymers bearing permanent pos. charges (PAHy-CPTA) with mol. weight of 10 kDa and PAHy-CPTA copolymers differing in pos. charge amount (18-58%) were chosen for biol. investigations. Biophys. properties of DNA/PAHy-CPTA polyplexes were evaluated in terms of DNA condensation, zeta potential and size distribution. Cytotoxicity studies on Neuro2A murine neuroblastoma cells evidenced absence of toxicity of these copolymers up to 300 μg/mL unlike linear polyethylenimine (LPEI) that was highly toxic already at 20 μg/mL. PAHy-CPTA copolymers did not induce any erythrocyte aggregation up to 1 mg/mL. Cellular interaction studies of PAHy-CPTA polyplexes evidenced a faster binding of these polyplexes with cells compared to DNA/LPEI polyplexes. The in vitro transfection ability of PAHy-CPTA polyplexes was strongly affected by exptl. conditions reaching about 10% of the transfection efficiency of optimized LPEI polyplexes. Finally, in vivo application studies confirmed the biocompatibility of PAHy-CPTA copolymers. With LPEI, clear signs of microvesicular fatty liver were observed and with LPEI polyplexes significant weight loss. In strong contrast, PAHy-CPTA did not induce histopathol. changes or weight loss.

Zhang, Hui published the artcileAltering intercomponent interactions in a photochromic multi-state [2]rotaxane, Quality Control of 219537-97-0, the publication is Organic & Biomolecular Chemistry (2011), 9(11), 4051-4056, database is CAplus and MEDLINE.

Rotaxanes have attracted much attention because of their challenging constructions and potential applications. In this paper, a multi-state [2]rotaxane, in which a dithienylethene-functionalized dibenzo-24-crown-8 macrocycle was interlocked onto a thread component bearing a 4-morpholin-naphthalimide fluorescent stopper and two distinct recognition sites, namely, dibenzylammonium and N-methyltriazolium recognition sites, was prepared and studied. By introducing a dithienylethene photochrome into the macrocycle component, multi-mode alteration of the intercomponent interactions, such as energy transfer, electron transfer, and charge transfer interaction between the photochrome and the fluorescent naphthalimide stopper could be altered in this multi-state rotaxane system in response to the combination of chem. and photochem. stimuli.

A new synthesis of entecavir from D-glucose in an average total yield of 3.5% was achieved via an intramol. nitrile oxide cycloaddition (INOC) reaction and a Peterson olefination as key-steps. The present process was designed for industrial application, using widely available raw materials, simple and cheap reagents and avoiding low reaction temperatures, which are very common in the synthetic approaches towards similarly complex structures.

Sasano, Yusuke published the artcile2-Azaadamantane N-oxyl (AZADO)/Cu Catalysis Enables Chemoselective Aerobic Oxidation of Alcohols Containing Electron-Rich Divalent Sulfur Functionalities, Category: chlorides-buliding-blocks, the publication is Organic Letters (2018), 20(19), 6104-6107, database is CAplus and MEDLINE.

The chemoselective oxidation of alcs. containing electron-rich sulfur functionalities (e.g., 1,3-dithianes and sulfides) into their corresponding carbonyl compounds with the sulfur groups can sometimes be a demanding task in modern organic chem. A reliable method for this transformation, which features azaadamantane-type nitroxyl radical/copper catalysis using ambient air as the terminal oxidant is reported. The superiority of the developed method was demonstrated by comparing it with various conventional alc. oxidation methods.

Employing a green and efficient 2,2,2-trifluoroacetophenone-catalyzed oxidation of alkenes, which utilized H₂O₂ as the green oxidant, a novel and sustainable synthesis of indolines and pyrrolidines was developed. This constituted a cheap, general and environmentally-friendly protocol for the synthesis of substituted nitrogen-containing heterocycles. A variety of substitution patterns, both aromatic and aliphatic moieties, were well tolerated led to the desired nitrogen heterocycles in good to excellent yields.

In this paper, we describe the stereospecific synthesis and functional properties of C₂– and C₁-sym. pyrene-fused [5]helicene mols. 1 and 2 connected via hexagonal and heptagonal rings, resp. Both mols. showed high configurational stability and distinct functional properties, which were attributed to the fusing mode of [5]helicene with the pyrene and mol. symmetry. The estimated Gibbs activation energy for enantiomerization of 2 is one of the highest reported values for any π-conjugated mols. incorporating [5]helicene moiety.

Gee, Clifford T. published the artcileFragment Screening and Druggability Assessment for the CBP/p300 KIX Domain through Protein-Observed ¹⁹F NMR Spectroscopy, COA of Formula: C8H7ClO3, the publication is Angewandte Chemie, International Edition (2015), 54(12), 3735-3739, database is CAplus and MEDLINE.

¹⁹F NMR spectroscopy of labeled proteins is a sensitive method for characterizing structure, conformational dynamics, higher-order assembly, and ligand binding. Fluorination of aromatic side chains has been suggested as a labeling strategy for small-mol. ligand discovery for protein-protein interaction interfaces. Using a model transcription factor binding domain of the CREB binding protein (CBP)/p300, KIX, we report the first full small-mol. screen using protein-observed ¹⁹F NMR spectroscopy. Screening of 508 compounds and validation by ¹H-¹⁵N HSQC NMR spectroscopy led to the identification of a minimal pharmacaphore for the MLL-KIX interaction site. Hit rate anal. for the CREB-KIX and MLL-KIX sites provided a metric to assess the ligandability or “druggability” of each interface informing future medicinal chem. efforts. The structural information from the simplified spectra and data collection speed, affords a new screening tool for anal. of protein interfaces and discovery of small mols.
