Chowdhury, Amiya K. Roy published the artcileR.S.(P), a new isolate from the root of Rauwolfia serpentina, Application of N-Benzyl-N,N-dimethyl-2-phenoxyethanaminium 3-hydroxy-2-naphthoate, the publication is Indian Medical Journal (1964), 58(12), 241-52, database is CAplus.

The pharmacol. actions of a nonalkaloidal fraction isolated from the root of R. serpentina are given. This fraction, R.S.(P), was less potent than reserpine but equipotent to Rauwolfia total extract (1%) in lowering the blood pressure in anesthetized cats. In suitable doses it increased the pentobarbital sleeping time, reduced the spontaneous motility, postponed Metrazol convulsion and lethality, and affected the conditioned behavior in rats (maze test). Coordinated muscular movements were least affected, except when very high doses were used. Electroencephalogram studies in unanesthetized rabbits revealed considerable slowing of the brain wave pattern with the calming and quieting effect on the animals. Sometimes behavioral nonreactivity was seen. The drug appeared to have a central site of action. Its action differed from that of reserpine in many respects. It may possibly be used as an antihypertensive and anticonvulsant or sedative agent.

Rajasekariah, G. R. published the artcileResponse of preadult Necator americanus to some known anthelminthics in hamsters, Recommanded Product: N-Benzyl-N,N-dimethyl-2-phenoxyethanaminium 3-hydroxy-2-naphthoate, the publication is Chemotherapy (Basel, Switzerland) (1986), 32(1), 75-82, database is CAplus and MEDLINE.

Hamsters infected with laboratory-adapted preadult N. americanus were dosed with 6 reference anthelmintics; their efficacy was measured in terms of percentage cure of infected animals as well as percentage worm reduction following treatment. Mebendazole and pyrantel were equally effective in this system. Other anthelmintics, including the anti-hookworm compound, bephenium hydroxynaphthoate, were less effective. The comparative results revealed that the N. americanus model is sensitive and reliable for identifying and characterizing new anti-parasite preparations

Rapid, sensitive, specific and validated colorimetric methods have been developed for the quant. estimation of ambroxol HCl in bulk and dosage form. The current method was developed based on oxidation of ambroxol with Gibb’s reagent (method I) and p-diethyl amino benzaldehyde in toluene (method II). The formed intense color complex was measured at 537.2 nm and 438.4 nm resp. Under optimized exptl. conditions, Beer’s law is obeyed in concentration range 5 – 30 μg/mL for both the methods with regression co-efficient 0.9994 and 0.9992. Recovery studies were conducted by standard addition method to confirm the accuracy of the method. The LOD and LOQ for the estimation of ambroxol were found as 0.0773, 0.2343 for method I and 0.0667, 0.2021 for method II resp. The proposed method was validated as per ICH guidelines.

Wei, Bing published the artcileChanges in Th1/Th2-producing cytokines during acute exacerbation chronic obstructive pulmonary disease, Recommanded Product: trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride, the publication is Journal of International Medical Research (2018), 46(9), 3890-3902, database is CAplus and MEDLINE.

This study aimed to explore cytokine serum levels and the ratio of type 1 T helper (Th1)/Th2 cells in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). A total 245 patients diagnosed with AECOPD and 193 patients who progressed to stable COPD after the initiation of treatment in hospital were selected, while a further 50 healthy individuals served as controls. All patients with COPD were diagnosed using Global Initiative for Chronic Obstructive Lung Disease criteria. Serum concentrations of interleukin (IL)-2, interferon (IFN)-γ, IL-4, IL-10, IL-17, and Ig (Ig)E were measured using enzyme-linked immunosorbent assays. AECOPD patients had higher levels of IL-2, IFN-γ, IL-4, IL-10, IL-17, and IgE than those with stable COPD or controls. Intriguingly, the ratios of Th1/Th2 and IL-17/IgE were lower in AECOPD patients compared with the other two groups. These data suggest that AECOPD patients produce more IgE and have more differentiated Th2 cells than other groups. Ur findings suggest that an imbalance of circulating CD4⁺ T cell subsets correlates with AECOPD, and that a shift of Th1/Th2 and IL-17/IgE ratios may be caused by increased Th2 cell production

Lee, Jonghee published the artcileEnhanced efficiency of polyfluorene derivatives: organic-inorganic hybrid polymer light-emitting diodes, Safety of 5,5′-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,2′-bithiophene, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2006), 44(9), 2943-2954, database is CAplus.

Two novel organic-inorganic hybrid polyfluorene derivatives, poly{(9,9′-dioctyl-2,7-fluorene)-co-(9,9′-di-POSS-2,7-fluorene)-co-[2,5-bis(octyloxy)-1,4-phenylene]} (PFDOPPOSS) and poly{(9,9′-dioctyl-2,7-fluorene)-co-(9,9′-di-POSS-2,7-fluorene)-co-bithiophene} (PFT2POSS), were synthesized by the Pd-catalyzed Suzuki reaction of polyhedral oligomeric silsesquioxane (POSS) appended fluorene, dioctyl phenylene, and bithiophene moieties. The synthesized polymers were characterized with ¹H NMR spectroscopy and elemental anal. Photoluminescence (PL) studies showed that the incorporation of the POSS pendant into the polyfluorene derivatives significantly enhanced the fluorescence quantum yields of the polymer films, likely via a reduction in the degree of interchain interaction as well as keto formation. Addnl., the blue-light-emitting polyfluorene derivative PFDOPPOSS showed high thermal color stability in PL. Moreover, single-layer light-emitting diode devices of an indium tin oxide/poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate)/polymer/Ca/Al configuration fabricated with PFDOPPOSS and PFT2POSS showed much improved brightness, maximum luminescence intensity, and quantum efficiency in comparison with devices fabricated with the corresponding pristine polymers PFDOP and PFT2. In particular, the maximum external quantum efficiency of PFT2POSS was 0.13%, which was twice that of PFT2 (0.06%), and the maximum current efficiency of PFT2POSS was 0.38 cd/A, which again was twice that of PFT2 (0.19 cd/A).

Gallaher, Joseph K. published the artcileEvolution of Nonmirror Image Fluorescence Spectra in Conjugated Polymers and Oligomers, Quality Control of 239075-02-6, the publication is Journal of Physical Chemistry Letters (2016), 7(17), 3307-3312, database is CAplus and MEDLINE.

The nonmirror image relation between absorption and fluorescence spectra of conjugated polymers contrasts with most organic chromophores and is widely considered a signature of interchromopohore energy funneling. The authors apply broad-band ultrafast fluorescence spectroscopy to resolve the evolution of fluorescence spectra for dilute solutions of conjugated oligothiophenes, where no energy transfer is possible. Fluorescence spectra evolve from a mirror image of absorption, which lacks vibronic structure, toward a spectrally narrower and vibronically structured species on the hundreds of femtosecond to early picosecond time scale. The authors’ anal. of this fluorescence spectral evolution shows that a broad distribution of torsional conformers is driven to rapidly planarize in the excited state, including in solid films, which is supported by Raman spectroscopy and quantum chem. modeling. The authors’ data have important implications for understanding different energy-transfer regimes that are delineated by structural relaxation.

Rout, Kanhu Charan published the artcileA copper(II) complex as selective turn-on fluorosensor for nitric oxide and its intracellular application, Category: alcohols-buliding-blocks, the publication is Inorganica Chimica Acta (2015), 201-206, database is CAplus.

A highly water soluble copper(II) complex, 1 of a fluorophore ligand 4-(2-hydroxybenzylamino)-5-hydroxynaphthalene-2,7-disulfonic acid (FL₁) was synthesized and characterized. In the complex, the fluorescence intensity of the ligand was found to quench due to the presence of paramagnetic Cu(II) center. In degassed methanol solution of complex 1, the Cu(II) center was found to undergo reduction in presence of nitric oxide. This resulted in the simultaneous formation of N-nitrosated ligand. In the process, the quenched fluorescence intensity of the ligand restored. The selective turn on fluorogenic nature of the complex 1 was used to study the endogenously produced NO in living cells.
