Sabatini, Stefano published the artcileRe-evolution of the 2-Phenylquinolines: Ligand-Based Design, Synthesis, and Biological Evaluation of a Potent New Class of Staphylococcus aureus NorA Efflux Pump Inhibitors to Combat Antimicrobial Resistance, Synthetic Route of 4584-49-0, the publication is Journal of Medicinal Chemistry (2013), 56(12), 4975-4989, database is CAplus and MEDLINE.

Overexpression of efflux pumps is an important mechanism by which bacteria evade the effects of antimicrobial agents that are substrates. NorA is a Staphylococcus aureus efflux pump that confers reduced susceptibility to many structurally unrelated agents, including fluoroquinolones, biocides, and dyes, resulting in a multidrug resistant (MDR) phenotype. In this work, a series of 2-phenylquinoline derivatives was designed by means of ligand-based pharmacophore modeling in an attempt to identify improved S. aureus NorA efflux pump inhibitors (EPIs). Most of the 2-phenylquinoline derivatives displayed potent EPI activity against the norA overexpressing strain SA-1199B. The antibacterial activity of ciprofloxacin, when used in combination with some of the synthesized compounds, was completely restored in SA-1199B and SA-K2378, a strain overexpressing norA from a multicopy plasmid. Compounds I and II also showed potent synergistic activity with the ethidium bromide dye in a strain overexpressing the MepA MDR efflux pump.

Toja, E. published the artcileAmnesia-reversal activity of a series of 5-alkoxy-1-arylsulfonyl-2-pyrrolidinones, Application In Synthesis of 32333-53-2, the publication is European Journal of Medicinal Chemistry (1991), 26(4), 403-13, database is CAplus.

A series of 5-alkoxy-1-arylsulfonyl-2-pyrrolidinones were prepared by condensation of arylsulfonyl chlorides with 5-alkoxy-2-pyrrolidinones. Most compounds reversed electroconvulsive shock-induced amnesia in mice, showing the typical inverted U-shaped dose-response curve. The results for 58 compounds indicate that the potency is maximum when there is a 5-ethoxy group and progressively declines as the ether alkyl chain is either elongated or shortened. Substitution on the Ph ring or its replacement with heterocyclic rings or its hydrogenation decreases the activity. The most promising compounds, with anti-amnesic properties superior in many respects (greater potency, greater efficacy and broader active dose-range) to those of piracetam and antiracetam were further evaluated for reversing scopolamine-induced amnesia and for their antihypoxic activity. 5-Ethoxy-1-phenylsulfonyl-2-pyrrolidinone and 5-(1-methylethoxy)-1-[3-(trifluoromethyl)phenylsulfonyl]-2-pyrrolidinone were selected for further evaluation because of their potent anti-amnesic and/or antihypoxic activity.

A series of siliceous adsorbents with chem. bonded phases (CBP) of different polarity were tested as sorbents for trapping air pollutants (petroleum ether) using controlled setup. Moreover, special attention was paid to the potential role of metal impurities as strong adsorption sites. Sorbents were characterized by various physico-chem. methods, such as porosimetry, inductively coupled plasma (ICP) anal., elemental anal., derivatog., and gas chromatog. Trapping tubes were utilized for sorption of toxic pollutants from indoor air: VOCs air anal. adsorbents surface characterization gas chromatog.

Kallepalli, Venkata A. published the artcileHarnessing C-H Borylation/Deborylation for Selective Deuteration, Synthesis of Boronate Esters, and Late Stage Functionalization, Name: 2-(3-Chloro-5-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane, the publication is Journal of Organic Chemistry (2015), 80(16), 8341-8353, database is CAplus and MEDLINE.

In the presence of iridium catalysts such as [Ir(cod)OMe]₂, aryl and heteroaryl mono- and di(pinacolboronates) underwent regioselective deborylation; reaction of aryl- and heteroaryl mono(pinacolboronates) using D₂O yielded regioselectively deuterated arenes, while deborylation of di(pinacolboronates) yielded mono(pinacolboronates) with different and complementary regioselectivity from a direct monoborylation. Di(pinacolboronates) were prepared using iridium-catalyzed borylation; diborylation and chemoselective deborylation reactions were performed in one pot in some instances. The iridium-catalyzed borylations were compared to palladium-catalyzed deborylations of diborylated indoles described by Movassaghi; for a 3-methylindole-derived diboronate and for three thiophenediboronates, the iridium-catalyzed conditions were more effective. Nonracemic clopidogrel was regioselectively deuterated and monoborylated using iridium-catalyzed mono- and diborylation and deborylation reactions.

Staderini, Matteo published the artcileA tripod anchor offers improved robustness of peptide-based electrochemical biosensors, Product Details of C19H14Cl2, the publication is Sensors and Actuators, B: Chemical (2018), 662-667, database is CAplus.

Peptide-based electrochem. biosensors have proven to be powerful sensing strategies for the detection of proteases and offer a highly versatile system, as simple tuning of the immobilized substrate peptide leads to a new sensing platform. The most common immobilization strategy of peptides onto an electrode surface is via a self-assembled monolayer (SAM) through a thiol group that can be readily chem. incorporated in the target peptide. However, the successful application of these platforms in complex biol. samples can be frustrated by the lack of stability of the peptide-based SAM, that can lead to false positives and limited shelf-life. Herein, we investigated the stability of a peptide-based electrochem. platform endowed with a single or a tribranched thiol group for attaching onto the electrode surface. Side-by-side comparison demonstrated that the tripod anchor generated a highly robust peptide-based electrochem. biosensor that showed improved stability when compared to the monoanchor analog, simplifying data anal. and interpretation, while showing efficient protease detection and similar sensing capabilities.
