Flaviviruses, including Zika, dengue, and West Nile viruses, are important human pathogens. The highly conserved NS2B-NS3 protease of Flavivirus is essential for viral replication and therefore a promising drug target. Through compound screening, followed by medicinal chem. studies, a novel series of 2,5,6-trisubstituted pyrazine compounds are found to be potent, allosteric inhibitors of Zika virus protease (ZVpro) with IC50 values as low as 130 nM. Their structure-activity relationships are discussed. The ZVpro inhibitors also inhibit homologous proteases of dengue and West Nile viruses, and their inhibitory activities are correlated. The most potent compounds 47 and 103 potently inhibited Zika virus replication in cells with EC68 values of 300-600 nM and in a mouse model of Zika infection. These compounds represent novel pharmacol. leads for drug development against Flavivirus infections.

SDS of cas: 63295-48-7. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Iron(III) trifluoromethanesulfonate, is researched, Molecular C3F9FeO9S3, CAS is 63295-48-7, about Mildly-doped polythiophene with triflates for molecular recognition. Author is Boujnah, Aicha; Boubaker, Aimen; Kalboussi, Adel; Lmimouni, Kamal; Pecqueur, Sebastien.

Organic semiconductors have enough mol. versatility to feature chemo-specific elec. sensitivity to large families of chem. substituents via different intermol. bonding modes. This study demonstrates that one single conducting polymer can be tuned to either discriminate water-, ethanol- or acetone-vapors, on demand, by changing the nature of its dopant. Seven triflate salts differ from mild to strong p-dopant on poly(3-hexylthiophene) sensing micro-arrays. Each material shows a pattern of conductance modulation for the polymer which is reversible, reproducible, and distinctive of other gas exposures. Based on principal component anal., an array doped with only two different triflates can be trained to reliably discriminate gases, which re-motivates using conducting polymers as a class of materials for integrated electronic noses. More importantly, this method points out the existence of tripartite donor-acceptor charge-transfer complexes responsible for chemospecific mol. sensing. By showing that mol. acceptors can have duality to p-dope semiconductors and to coordinate donor gases, such behavior can be used to understand the role of frontier orbital overlapping in organic semiconductors, the formation of charge-transfer complexes via Lewis acid-base adducts in mol. semiconductors.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis, thermal, mass and ab initio analyses of cyclopropane-1,1,2-tricarboxylic acid, published in 2004-06-07, which mentions a compound: 600-05-5, mainly applied to cyclopropanetricarboxylic acid preparation DSC IR proton NMR MS, Reference of 2,3-Dibromopropionic acid.

The preparation of cyclopropane-1,1,2-tricarboxylic acid from cyanoacetic acid and 2,3-dibromopropionic acid has been carried out in a one-step procedure in alk. medium. The compound has been characterized, by NMR, mass spectrometry, and thermal analyses. The mass spectrum showed the mol. ion peak in the neg. mode. The thermal anal. results show that the compound decomposes in three steps, and the second step of decomposition was tentatively assigned to the loss of two carboxylic acid groups. Also, theor. calculations were made in order to assign vibrations and determine the most stable structure for the compound

A new NMR approach is proposed for the measurement of long-range heteronuclear coupling constants (n JXH, n > 1) in natural abundance mols. Two complementary in-phase (IP) and anti-phase (AP) data are sep. recorded from a modified HSQMBC experiment and then added/subtracted to provide spin-state-selective α/β-HSQMBC spectra. The magnitude of n JXH can be directly determined by simple anal. of the relative displacement between α- and β-cross-peaks. The robustness of this IPAP-HSQMBC experiment is evaluated exptl. and by simulation using a variety of different conditions. Important aspects such as signal intensity dependence and presence of unwanted cross-talk effects are discussed and examples on the measurement of small proton-carbon (n JCH) and proton-nitrogen (n JNH) coupling constants are provided.

Name: Tris(3,5-bis(trifluoromethyl)phenyl)phosphine. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Tris(3,5-bis(trifluoromethyl)phenyl)phosphine, is researched, Molecular C24H9F18P, CAS is 175136-62-6, about Ruthenium and rhodium nanoparticles as catalytic precursors in supercritical carbon dioxide. Author is Escarcega-Bobadilla, Martha V.; Tortosa, Clara; Teuma, Emmanuelle; Pradel, Christian; Orejon, Aranzazu; Gomez, Montserrat; Masdeu-Bulto, Anna M..

Ruthenium and rhodium nanoparticles (MNP) were prepared in the presence of phosphine ligands containing fluorinated groups, starting from well-defined organometallic compounds The syntheses of these new materials evidenced the crucial tuning between metal precursor and ligand. These nanocatalysts were used in hydrogenation reactions of arene derivatives in organic solvent (THF) and supercritical carbon dioxide (scCO2). The catalytic behavior observed (activity and selectivity) showed that both Ru and Rh systems are less active in scCO2 than in THF, preventing the hydrogenation of the aromatic group when electron-donor groups (like ether moieties) are present on the substrate.

Safety of Tris(3,5-bis(trifluoromethyl)phenyl)phosphine. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Tris(3,5-bis(trifluoromethyl)phenyl)phosphine, is researched, Molecular C24H9F18P, CAS is 175136-62-6, about Probing steric influences on electrophilic phosphonium cations: a comparison of [(3,5-(CF3)2C6H3)3PF]+ and [(C6F5)3PF]+. Author is LaFortune, James H. W.; Szkop, Kevin M.; Farinha, Farah E.; Johnstone, Timothy C.; Postle, Shawn; Stephan, Douglas W..

The electrophilic phosphonium cation (EPC) salt [(3,5-(CF3)2C6H3)3PF][B(C6F5)4] (2) was prepared via oxidation of the precursor phosphine with XeF2 and subsequent abstraction of fluoride with [Et3Si(tol)][B(C6F5)4]. The Lewis acidity of 2 is evaluated by exptl. and computational methods and by preliminary catalysis testing. Exchange reactions of 2 and [(C6F5)3PF][B(C6F5)4] with their resp. difluorophosphoranes were studied by 2-dimensional 19F-19F NOESY/EXSY and selective 1-dimensional 19F NMR exchange spectroscopy (SEXSY) experiments affording comparative rates of fluoride exchange. Collectively, although 2 is less Lewis acidic than [(C6F5)3PF][B(C6F5)4], the improved access to the P center of 2 provides a kinetic acceleration for fluoride exchange and catalysis where the transition states are more sterically demanding.

A Journal, European Journal of Organic Chemistry called Iron Triflate Salts as Highly Active Catalysts for the Solvent-Free Oxidation of Cyclohexane, Author is Payard, Pierre-Adrien; Zheng, Yu-Ting; Zhou, Wen-Juan; Khrouz, Lhoussain; Bonneviot, Laurent; Wischert, Raphael; Grimaud, Laurence; Pera-Titus, Marc, which mentions a compound: 63295-48-7, SMILESS is O=S(C(F)(F)F)([O-])=O.O=S(C(F)(F)F)([O-])=O.O=S(C(F)(F)F)([O-])=O.[Fe+3], Molecular C3F9FeO9S3, Formula: C3F9FeO9S3.

Among a series of iron salts, iron triflates revealed as highly active catalysts for the oxidation of cyclohexane by tert-Bu hydroperoxide into cyclohexanol and cyclohexanone with initial turnover frequencies higher than 10,000 h-1. The structure of the iron complexes under the reaction conditions was studied by combining ESR (EPR) spectroscopy and DFT calculations The coordination of the catalytic iron center readily evolved in the presence of the reaction products, leading ultimately to its deactivation. Iron and organic superoxo intermediates were identified as plausible active species allowing to rationalize the high activity of iron ligated by highly delocalized counter-anions.
