Murugesan, Kathiravan published the artcileReductive amination using cobalt-based nanoparticles for synthesis of amines, Application In Synthesis of 350-30-1, the publication is Nature Protocols (2020), 15(4), 1313-1337, database is CAplus and MEDLINE.

In this protocol, the preparation of carbon-supported cobalt-based nanoparticles as efficient and practical catalysts for synthesis of different kinds of amines by reductive aminations was described. Template synthesis of a cobalt-triethylenediamine-terephthalic acid metal-organic framework on carbon and subsequent pyrolysis to remove the organic template resulted in the formation of supported single cobalt atoms and nanoparticles. Applying these catalysts, structurally diverse benzylic, aliphatic and heterocyclic primary, secondary and tertiary amines, including pharmaceutically relevant products, starting from inexpensive and easily accessible carbonyl compounds with ammonia, nitro compounds or amines and mol. hydrogen were synthesized. To prepare this cobalt-based catalyst took 26 h, and the reported catalytic reductive amination reactions could be carried out within 18-28 h.

Nayak, Sabita published the artcileDesign and Synthesis of (E)-4-(2-Phenyl-2H-chromen-3-yl)but-3-en-2-ones and Evaluation of their In Vitro Antimicrobial Activity, Recommanded Product: 5-Bromo-3-chloro-2-hydroxybenzaldehyde, the publication is Letters in Organic Chemistry (2015), 12(5), 352-358, database is CAplus.

2H-Chromene and its derivatives are an important class of organic compounds due to their wide range of biol. activities such as antimicrobial, antiviral, antiinflammatory and antitubercular agents. In the present work, we have synthesized ten new 2H-chromene derivatives [(E)-4-(2-phenyl-2H-chromen-3-yl)but-3-en-2-one and its substituted analogs] by aldol condensation of 2H-chromene-3-carbaldehydes with acetone. These products have been characterized by means of spectral data (1H, 13C, IR, Mass). The structure of (E)-4-(6,8-dichloro-2-phenyl-2H-chromen-3-yl)but-3-en-2-one was confirmed by X-ray anal. The compounds were evaluated for in vitro antimicrobial activity against two Gram pos. bacteria [Streptococcus mutans (MTCC 497) and Streptococcus pyogenes (MTCC 1926)] and three Gram neg. bacteria [Vibrio cholera (MTCC 3909), Shigella flexneri (MTCC 1457) and Salmonella enteric typhi (MTCC 1252)]. The obtained results from in vitro antimicrobial assays by the broth dilution method indicated that many of the compounds exhibited excellent activity against all the microorganisms in comparison to standard kanamycin.

Sen, Rajendra Nath published the artcileAlkali sulfonates of coumarin and nitrocoumarin, Formula: C9H5ClO4S, the publication is Journal of the Indian Chemical Society (1928), 433-7, database is CAplus.

The positions of the SO₃H groups in coumarinmono- (I) and -disulfonic acid (II) prepared by Perkin (J. Chem. Soc. 24, 37), and of the 6-nitrocoumarinsulfonic acid (III) were determined For this purpose, the ordinary methods were not applicable; alkali fusion, e. g., leading to a rupture in the lactonic ring of the coumarin mol. Therefore the lactonic ring was oxidized with KMnO₄ and known derivatives of o-HOC₂H₄CO₂H (IV) obtained. Thus I was shown to be coumarin-6 sulfonic acid. In III, the SO₃H group occupies a position in the lactone ring and is probably 6-nitrocoumarin-3-sulfonic acid in analogy with 3,6-dinitrocoumarin (J. Chem. Soc. 97, 1397), and similarly, II is probably coumarin-3,6-disulfonic acid. Some new derivatives of I, II and III were prepared The process of preparing I, II and III was improved by precipitating the SO₃H acids as the Na salts, and in the case of II, by substituting the ordinary fuming H₂SO₄ by 50% fuming H₂SO₄. Ten g. coumarin heated with 50 g. fuming H₂SO₄ for 2 h. on the water bath, cooled, filtered into saturated NaCl solution and kept for 1-2 days, gave 85% of the Na salt (V) of I; this salt gave with PCl₆ or POCl₃, the sulfonyl chloride (VI), m. 115°; from VI were prepared the amide, m. 186°, and the anilide, m. 132°. For the oxidation, V was dissolved in 2 N KOH and 4% KMnO₄ was slowly added at 0-10°. When the oxidation was complete, the solution was heated for 1 h. on the water bath, filtered, concentrated, and concentrated HCl added. The resulting acid K salt of 5,2-HO₃S(HO)C₆H₃CO₂,H (VII) was filtered off, recrystallized, and converted to the free acid. Na salt (VIII) of II, from 10 g. coumarin and 70 g. 50% fuming H₂SO₄ by heating for 3-4 h. to 150° on the oil bath, cooling and precipitating with NaCl solution Recrystallization gives VIII in 70% yield; disulfonyl chloride, m. 170-3°; diamide, m.above 240°, dianilide, yellow. Oxidation of VIII, carried out as in the case of V, leads to formation of VII. Na salt (IX)of III, (80% from 10g. 6-nitrocoumarin and 60 g. 50% fuming H₂SO₄ by heating to 150° for 3-4 h. and precipitating with NaCl solution), yellowish; sulfonyl chloride, m. 205°; amide, does not m. 260°; anilide, m. 130°. The product of oxidation of IX was identified as 5,2-O₂N(HO)C₆H₂3CO₂H.

Ortiz Zacarias, Natalia V. published the artcileDesign and Characterization of an Intracellular Covalent Ligand for CC Chemokine Receptor 2, SDS of cas: 32333-53-2, the publication is Journal of Medicinal Chemistry (2021), 64(5), 2608-2621, database is CAplus and MEDLINE.

Covalently acting inhibitors constitute a large and growing fraction of approved small-mol. therapeutics as well as useful tools for a variety of in vitro and in vivo applications. Here, we aimed to develop a covalent antagonist of CC chemokine receptor 2 (CCR2), a class A GPCR that has been pursued as a therapeutic target in inflammation and immuno-oncol. Based on a known intracellularly binding CCR2 antagonist, several covalent derivatives were synthesized and characterized by radioligand binding and functional assays. These studies revealed compound 14 as an intracellular covalent ligand for CCR2. In silico modeling followed by site-directed mutagenesis confirmed that 14 forms a covalent bond with one of three proximal cysteine residues, which can be engaged interchangeably. To our knowledge, compound 14 represents the first covalent ligand reported for CCR2. Due to its unique properties, it may represent a promising tool for ongoing and future studies of CCR2 pharmacol.

Kosevich, Marina V. published the artcileIs there a ‘matrix suppression effect’ under fast-atom bombardment liquid secondary ion mass spectrometry of ionic surfactants in glycerol?, SDS of cas: 38146-42-8, the publication is Rapid Communications in Mass Spectrometry (2007), 21(4), 466-478, database is CAplus.

Some features of a ‘matrix suppression effect’ caused by ionic surface-active compounds under fast-atom bombardment (FAB) liquid secondary ion mass spectrometry (LSIMS) are being revised. It is shown that abundant transfer of the glycerol matrix mols. to the gas phase does occur under FAB-LSIMS of ionic surfactants, contrary to popular belief. This process can be obscure because of the dependence of the charge state of the glycerol-containing cluster ions on the type of ionic surfactant. It is revealed that, while glycerol matrix signals are really completely suppressed in the pos. ion mass spectra of cationic surfactants (decamethoxinum, aethonium), abundant deprotonated glycerol and glycerol-anion clusters are recorded in the neg. ion mode. In the case of an anionic surfactant (sodium dodecyl sulfate), on the contrary, glycerol is completely suppressed in the neg. ion mode, but is present in the protonated and cationized forms in the pos. ion mass spectra. It is suggested that such patterns of pos. and neg. ion FAB-LSIMS spectra of ionic surfactants solutions reflect the structure and composition of the elec. double layer formed at the vacuum-liquid interface by organic cations or anions and their counterions. Processes leading to the formation of the glycerol-containing ions preferentially of pos. or neg. charge are discussed. The most obvious of them is efficient binding of glycerol to inorganic counterions of the salts Cl^– or Na⁺, which is confirmed by data from quantum chem. calculations The high content of the counterions and relatively small content of glycerol in the sputtered zone may be responsible for the charge-selective suppression of neat glycerol clusters of opposite charge to the counterions. In the case of a mixture of cationic and anionic surfactants the substitution of inorganic counterions by organic ones was observed The dependence of the exchange rate in the surface layer is not a linear function of the bulk solution concentration, and an effect of abrupt recharging of the surface can be registered. No both pos. or neg. charged pure glycerol and glycerol-inorganic counterion clusters are recorded for the mixture Correlations between the mass spectrometric observations and some phenomena of surface and colloid chem. and physics are discussed.

The authors have explored two divinylbenzene cross-linked polystyrene supports for use in a solid-supported N-terminal peptide tagging strategy. Resin-bound tags designed to be cleaved in a single step at the N-terminus of peptides have been devised and explored as peptide N-terminal tagging reagents (constructs) for subsequent mass spectrometric anal. While the brominated tagging approach shows promise, the use of these specific solid supports has drawbacks, in terms of tagging reaction scale, for real applications in proteomics.

Anchordoguy, Thomas J. published the artcileInsights into the cryoprotective mechanism of dimethyl sulfoxide for phospholipid bilayers, Name: trimethyloxosulphonium chloride, the publication is Cryobiology (1991), 28(5), 467-23, database is CAplus and MEDLINE.

DMSO is a widely used cryoprotectant for biol. structures such as membranes. Despite hundreds of studies on the effects of this mol., surprisingly little is known about its cryoprotective mechanism. This study investigates the ability of various DMSO analogs to serve as cryoprotectants for liposomes. The data show that an increase in hydrophobicity progressively reduces the cryoprotective effect of sulfoxides. Addnl. experiments using phospholipid vesicles of varying composition demonstrate that DMSO is markedly less effective on liposomes carrying a net neg. charge. In fact, cryoprotection by DMSO was virtually eliminated in vesicles composed of 30% phosphatidylserine (a neg. charged lipid). Based on these results, it is suggested that the polar sulfoxide moiety of DMSO interacts electrostatically with phospholipid membranes and that this interaction is critical for DMSO’s cryoprotective effect for membranes.

A novel series of aminopyridine N-oxides, e.g. I, were designed, synthesized, and tested for their ability to inhibit p38α MAP kinase. Some of these compounds showed a significant reduction in the LPS-induced TNFα production in human whole blood. Structure-activity relationship studies revealed that N-oxide oxygen was essential for activity and was probably a determinant factor for a marked selectivity against other related kinases. Compound I was identified as a potent and selective p38α inhibitor with an appropriate balance between potency and pharmacokinetics. In vivo efficacy of I was demonstrated in reducing TNFα levels in an acute murine model of inflammation (ED₅₀ = 1 mg/kg in LPS-induced TNFα production when dosed orally 1.5 h prior to LPS administration). The oral efficacy of I was further demonstrated in a chronic model of adjuvant arthritis in rats with established disease when administered orally (ED₅₀ = 4.5 mg/kg).
