Waschbusch, Rachel published the artcileA new route to α-fluorovinylphosphonates utilizing Peterson olefination methodology, Formula: C5H10Cl3O3P, the publication is Tetrahedron (1996), 52(45), 14199-14216, database is CAplus.

Several α-fluorovinylphosphonates were synthesized from the Peterson olefination reaction applied to both aldehydes and ketones in conjunction with α-lithiated-α-fluoro-α-trimethylsilymethylphosphonate. The reaction with aldehydes gives mainly the E-isomer whereas reaction with ketones gives mainly the Z-isomer. The authors propose a closed transition state to explain the results.

Abrams, Rachel P. published the artcileFive-Membered Ring Peroxide Selectively Initiates Ferroptosis in Cancer Cells, Formula: C10H15ClO3S, the publication is ACS Chemical Biology (2016), 11(5), 1305-1312, database is CAplus and MEDLINE.

A 1,2-dioxolane (FINO₂) was identified as a lead compound from a screen of organic peroxides. FINO₂ does not induce apoptosis, but instead initiates ferroptosis, an iron-dependent, oxidative cell death pathway. Few compounds are known to induce primarily ferroptosis. In contrast to the perceived instability of peroxides, FINO₂ was found to be thermally stable to at least 150 °C. FINO₂ was more potent in cancer cells than nonmalignant cells of the same type. One of the enantiomers was found to be more responsible for the observed activity.

Prochloraz is a widely used imidazole fungicide that has to be analyzed together with its metabolites or transformation products for food safety monitoring purposes in the European Union. Although the focus in food of plant origin has been set on metabolites BTS 44595 and BTS 44596, we consider relevant the study of BTS 40348 metabolite, too, because it has been detected in both raw and processed foods based on citrus fruits in the EU. Metabolite BTS 40348 should be monitored in surface water due to its ecotoxicol. effects. In this work, the synthesis and structural characterization of BTS 40348 metabolite of fungicide prochloraz is presented, because the structure is closely related to the chem. and biol. activity of the substance. Characterization using ¹³C and ¹H NMR, IR, and Raman spectroscopy is detailed, together with confirmation by electrospray mass spectrometry anal.

Lumeras, Wenceslao published the artcileDesign, Synthesis, and Structure-Activity Relationships of Aminopyridine N-Oxides, a Novel Scaffold for the Potent and Selective Inhibition of p38 Mitogen Activated Protein Kinase, Synthetic Route of 209919-30-2, the publication is Journal of Medicinal Chemistry (2009), 52(17), 5531-5545, database is CAplus and MEDLINE.

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).

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.

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.

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.
