Low band gap donor-acceptor phenothiazine copolymer with triazine segment: Design, synthesis and application for optical limiting devices

Soluble conjugated donor-acceptor phenothiazine-N-piperidine substituted triazine copolymer (P(PZ-TN)) has been designed and synthesized via Suzuki coupling reaction. To investigate the variation in band structure of the copolymer, quantum-chemical calculation using DFT theory was carried out in the periodic boundary condition (PBC) formalism at HSE06 and B3LYP correlation function using 6-31 G basis set. The insertion of triazine unit as an alternating monomer in the copolymer of phenothiazine and triazine lowers the HOMO and LUMO energy levels. The optical band gap of the copolymer was calculated to be 2.5 and 2.3 eV in THF solution and as thin film, respectively from the onset of low energy optical transition. In thin film, the energy gap tends to narrow and the absorption and emission peaks are red shifted owing to the better interaction and increase in planarity of the copolymer in thin film. Theoretical studies along with photophysical and electrochemical studies confirmed that the copolymer exhibited relatively low band gap than that of homopolymer. The absorption and emission spectra of the copolymer, in solvents of varying polarity showed positive solvatochromism. The third-order nonlinear optical properties of copolymer, P(PZ-TN) were investigated by Z-scan technique at 532 nm. The copolymer showed strong third-order nonlinear optical susceptibility and low optical limiting threshold values of 1.27 x 10(-11) esu and 0.22 GW/cm(2), respectively.

Copper-catalyzed asymmetric dearomative borylation: new pathway to optically active heterocyclic compounds

Chiral N-heterocyclic organoboronates represent promising intermediates for the preparation of various bioactive and pharmaceutical compounds. We recently reported the first asymmetric dearomative borylation of indoles by copper-catalyzed borylation. Then we further developed dearomatization/enantioselective borylation sequence. Chiral 3-boryl-tetrahydropyridines and chiral boryl-tetrahydroquinolines via the copper(I)-catalyzed regio-, diastereo- and enantioselective borylation of 1,2-dihydropyridines and 1,2-dihydroquinilines, which were prepared by the partial reduction of the corresponding pyridine or quinoline derivatives. This dearomatization/enantioselective borylation procedures provide a direct access to chiral piperidines and tetrahydroquinolines from readily available pyridines or quinolines in combination with the stereospecific transformation of the stereogenic C-B bond.

New approach for determination of the degradation products of fenspiride hydrochloride found in oral liquid formulations

Fenspiride hydrochloride (FNS) is used in treating chronic inflammatory diseases, most commonly as a liquid oral solution. FNS produces degradation products along with fenspiride N-oxide (FNO) and 1-phenylethyl-4-hydroxy-4-aminomethyl piperidine hydrochloride (PHAP). We aimed to develop and validate a chromatographic method in order to identify the main degradation products in the presence of other compounds from a liquid preparation. The method used a dual gradient using two buffer solutions: the first with pH4.5 (buffer 1, pH4.5-MeOH 90:10%, v/v) and the second with pH2.9 (buffer 2, pH2.9-acetronitrile-methanol, 65:15:10%, v/v/v). As mentioned, there was a modification of the organic mixture, starting with 10% methanol and ending with a mixture of acetonitrile-methanol (15:10%, v/v). The flow-rate was 1.5mL/min. According to the elution program, experimental conditions started with 100% solution S1, which decreased to 0% and, simultaneously, solution S2 increased to 100% during the first 10min and was maintained for a further 5min. After 15min, initial conditions were re-established. The linearity interval was 0.5-2g/mL and the minimum correlation coefficient was 0.999. The recovery factor was 100.47-103.17% and the limit of quantification was 0.19-0.332g/mL. Intra-day maximum precision was 4.08% for FNS and 2.65% for PHAP. This double-gradient mobile phase produced good specificity in relation to the degradation products of FNS and other constituents of the oral liquid formulation. Forced degradation studies revealed other related substances that were confirmed in mass balance analyses. Degradation products were confirmed in acidic, basic and oxidative media.

Application of 143900-44-1, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 143900-44-1.

Catalytic Access to Bridged Sila-N-heterocycles from Piperidines via Cascade sp(3) and sp(2) C-Si Bond Formation

Described herein is the development of an unprecedented route to bridged sila-N-heterocycles via B(C6F5)(3)-catalyzed cascade silylation of N-aryl piperidines with hydrosilanes. Mechanistic studies indicated that an outer-sphere ionic path is operative to involve three sequential catalytic steps having N-silyl piperidinium borohydride as a resting species: (i) dehydrogenation of the piperidine ring, (ii) beta-selective hydrosilylation of a resultant enamine intermediate, and (iii) intramolecular dehydrogenative sp(2) C-H silylation.

Design, synthesis and antibacterial evaluation of honokiol derivatives

Staphylococcus aureus is a major and dangerous human pathogen that causes a range of clinical manifestations of varying severity, and is the most commonly isolated pathogen in the setting of skin and soft tissue infections, pneumonia, suppurative arthritis, endovascular infections, foreign-body associated infections, septicemia, osteomyelitis, and toxic shocksyndrome. Honokiol, a pharmacologically active natural compound derived from the bark of Magnolia officinalis, has antibacterial activity against Staphylococcus aureus which provides a great inspiration for the discovery of potential antibacterial agents. Herein, honokiol derivatives were designed, synthesized and evaluated for their antibacterial activity by determining the minimum inhibitory concentration (MIC) against S. aureus ATCC25923 and Escherichia coli ATCC25922 in vitro. 7c exhibited better antibacterial activity than other derivatives and honokiol. The structure-activity relationships indicated piperidine ring with amino group is helpful to improve antibacterial activity. Further more, 7c showed broad spectrum antibacterial efficiency against various bacterial strains including eleven gram-positive and seven gram-negative species. Time-kill kinetics against S. aureus ATCC25923 in vitro revealed that 7c displayed a concentration-dependent effect and more rapid bactericidal kinetics better than linezolid and vancomycin with the same concentration. Gram staining assays of S. aureus ATCC25923 suggested that 7c could destroy the cell walls of bacteria at 1 x MIC and 4 x MIC. (C) 2017 Published by Elsevier Ltd.

Immunostimulating properties of the azaheterocyclic compounds BIV-3, BIV-4, BIV-7

In animals and humans, immune system performs an important function to maintain the constancy of the body internal environment, carried out by recognizing and eliminating alien substances of antigenic nature from the body. This immune system function is carried out with the congenital and acquired immunity factors. Different types of radiation, heavy metal salts, vitamin and micronutrient deficiency, stressful situations, age-related changes in the lympho-myeloid complex, therapy with anti-tuberculosis, antibacterial, hormonal, cytostatic drugs and a number of other factors lead to the development of immune diseases. These diseases can be treated with a set of immunotherapy methods; use of immunostimulants is one of them. Today, immunostimulants are distinguished as of microbial, thymic, bone marrow, cytokine, nucleic, plant and synthetic origin. Azaheterocyclic compounds comprise a class of compounds that have demonstrated significant biological activities against various human diseases. We suggest that azaheterocyclic compounds with a piperidine nucleus are perspective for the search for new effective immunostimulating drugs. To study their immunostimulating activity, the following compounds were taken: BIV-3 – 1-(3-butoxypropyl)-3-methylpiperidine 4-spiro 5′-imidazolidine-2′,4′-dione, BIV-4 – 1-(2-ethoxyethyl)-4-hydroxy-4-dimethoxyphosphorylpipericline, BIV-7 – complex of 3-(2-morpholinoethyl)-7-(3-isopropoxypropyl)-3,7-diazabicyclo [3.3.1] nonane with beta-cyclodextrin. The comparison drug was methyluracil. Results of the studies are presented in this paper.
