We report the synthesis and properties of π-stacked polymers consisting of oligothiophene and naphthalene as the stacked π-system and the scaffold, resp. The titled polymers were obtained by the Suzuki-Miyaura coupling reaction. Oligothiophene units were layered in proximity, ∼3.0 Å from each other. Contribution of the quinoidal structure of the oligothiophene units involving the naphthalene scaffolds in the excited state resulted in relatively high photoluminescence quantum efficiencies. The polymers have potential application to optoelectronic devices such as hole-transporting materials. Polymer Journal (2010) 42, 928-934; doi:10.1038/pj.2010.101; published online 27 Oct. 2010.

Morisaki, Yasuhiro published the artcileXanthene-Based Oligothiophene-Layered Polymers, SDS of cas: 239075-02-6, the publication is Macromolecular Chemistry and Physics (2010), 211(22), 2407-2415, database is CAplus.

We synthesized xanthene-based oligothiophene-layered polymers containing bithiophenes, terthiophenes, quaterthiophenes and quinquethiophenes by the Suzuki-Miyaura coupling reaction. The polymers were characterized by various spectroscopic and electrochem. methods. They were well soluble in common organic solvents and thermally stable. Effective π-π interactions among the layered oligothiophene units in the polymer backbone were not observed in the ground state as well as in the excited state. A possible application of the polymers in opto-electronic devices such as hole transporting materials is expected.

Mitini-Nkhoma, Steven C. published the artcileIon transport modulators differentially modulate inflammatory responses in THP-1-derived macrophages, Recommanded Product: trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride, the publication is Journal of Immunology Research (2021), 8832586, database is CAplus and MEDLINE.

Ion transport modulators are most commonly used to treat various noncommunicable diseases including diabetes and hypertension. They are also known to bind to receptors on various immune cells, but the immunomodulatory properties of most ion transport modulators have not been fully elucidated. We assessed the effects of thirteen FDA-approved ion transport modulators, namely, ambroxol HCl, amiloride HCl, diazoxide, digoxin, furosemide, hydrochlorothiazide, metformin, omeprazole, pantoprazole, phenytoin, verapamil, drug X, and drug Y on superoxide production, nitric oxide production, and cytokine expression by THP-1-derived macrophages that had been stimulated with ethanol-inactivated Mycobacterium bovis BCG. Ambroxol HCl, diazoxide, digoxin, furosemide, hydrochlorothiazide, metformin, pantoprazole, phenytoin, verapamil, and drug Y had an inhibitory effect on nitric oxide production, while all the test drugs had an inhibitory effect on superoxide production Amiloride HCl, diazoxide, digoxin, furosemide, phenytoin, verapamil, drug X, and drug Y enhanced the expression of IL-1β and TNF-α. Unlike most immunomodulatory compounds currently in clin. use, most of the test drugs inhibited some inflammatory processes while promoting others. Ion pumps and ion channels could therefore serve as targets for more selective immunomodulatory agents which do not cause overt immunosuppression.

Boltia, Shereen A. published the artcileFour validated spectrophotometric methods for determination of ambroxol, guaifenesin, and theophylline in their ternary mixture in bulk powder and dosage form, Application In Synthesis of 23828-92-4, the publication is Journal of Pharmacy Research (Mohali, India) (2018), 12(4), 446-454, database is CAplus.

The purpose of the present study was to develop and validate spectrophotometric methods for simultaneous determination of a ternary mixture of ambroxol HCl (AMB), guaifenesin (GUA) and theophylline (THEO) in pharmaceutical dosage forms. (a) Direct spectrophotometry (DS), (b) dual wavelength (DW), (c) first derivative of ratio spectra (1DD), and (d) absorption correction (AC). DS method was applied to determine AMB at its λmax (309.0 nm) without any interference of THEO and GUA. Both THEO and GUA were determined as a binary mixture after removal of AMB contribution from the ternary mixture by ratio subtraction technique. DW method was applied to determine GUA by measuring the difference in absorbance at 224.5 nm and 255.0 nm. 1DD was used to determine THEO at 295.4 nm and GUA at 236.5 nm using 14.0μg/mL GUA and 14.5μg/mL THEO as divisors, resp. AC was applied after the second derivative for determination of GUA at 239.5 nm and THEO at 239.5 nm and 266.0 nm. The methods were accurate, specific, and successfully applied for the determination of the three drugs in laboratory prepared mixtures and their combined dosage form.

Donnelly, Liam J. published the artcileC-H Borylation Catalysis of Heteroaromatics by a Rhenium Boryl Polyhydride, Application of 5,5′-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,2′-bithiophene, the publication is ACS Catalysis (2021), 11(12), 7394-7400, database is CAplus.

Transition metal complexes bearing metal-boron bonds are of particular relevance to catalytic C-H borylation reactions, with iridium polyboryl and polyhydrido-boryl complexes the current benchmark catalysts for these transformations. Herein, we demonstrate that polyhydride boryl phosphine rhenium complexes are accessible and catalyze the C-H borylation of heteroaromatic substrates. Reaction of [K(DME)(18-c-6)][ReH₄(Bpin)(η²-HBpin)(κ²-H₂Bpin)] 1 with 1,3-bis(diphenylphosphino)propane (dppp) produced [K(18-c-6)][ReH₄(η²-HBpin)(dppp)] 2 through substitution of two equivalent of HBpin, and protonation of 2 formed the neutral complex [ReH₆(Bpin)(dppp)] 3. Combined X-ray crystallog. and DFT studies show that 2 is best described as a σ-borane complex, whereas 3 is a boryl complex. Significantly, the boryl complex 3 acted as a catalyst for the C(sp²)-H borylation of a variety of heteroarenes (14 examples including furan, thiophene, pyrrole and indole derivatives) and displayed similar reactivity to the iridium analogs.

Wasin, Tuchinda published the artcileFabrication of “Clickable” Polyfluorene Nanowires with High Aspect Ratio as Biological Sensing Platforms, Related Products of alcohols-buliding-blocks, the publication is ACS Sensors (2016), 1(6), 766-774, database is CAplus.

“Clickable” nanowires with well-defined and uniform structures made of conjugated polyfluorene polymers were successfully fabricated by single particle nanofabrication technique (SPNT). Poly[(9,9-dihex-5-yn-1-ylfluorenyl-2,7-diyl)-co-(9,9′-di-n-octylfluorenyl-2,7-diyl)] (F6E8) and poly[(9,9-dihex-5-yn-1-ylfluorenyl-2,7-diyl)-co-(2,2′-bithiophene)] (F6E2T) underwent an efficient crosslinking reaction upon irradiation, resulting in formation of one-dimensional nanostructures with high and desired aspect ratio reaching up to 200. Alkyne groups on the surface of nanowires were functionalized effectively by click reaction with fluorescent 5-TAMRA-PEG3-azide, which was confirmed by confocal microscopy. Substrates functionalized with the nanowires provide dramatic expansion of “clickable” surface area immobilized directly with TAMRA, and the fluorescence resonance energy transfer (FRET) processes between TAMRA and nanowire backbones are demonstrated as biol. sensing platforms.

Arriaga Alba, M. published the artcileMutagenicity of urine from mice exposed orally to nitrite and various aminated antiparasitic drugs, Application of N-Benzyl-N,N-dimethyl-2-phenoxyethanaminium 3-hydroxy-2-naphthoate, the publication is Environmental and Molecular Mutagenesis (1989), 14(1), 13-19, database is CAplus and MEDLINE.

The mutagenic activity of mouse urine was determined after oral administration of sodium nutrite and pyrantel pamoate, chloroquine, piperazine, dehydroemetine, iodochlorhydroxyquin, and bephenium hydroxynaphthoate. The simultaneous administration of piperazine or chloroquine with sodium nitrite produced urinary mutagens that appeared conjugated as glucuronides, whereas pyrantel pamoate and dehydroemetine in the presence of nitrite caused only slight mutagenic urine. No mutagenic activity was detected in the urine of mice to which halogenated derivatives of tertiary amines (iodochlorhydroxyquin) or quaternary ammonium salts (bephenium hydroxynaphthoate) were administered together with nitrite.
