A series of 9-substituted 1,2,3,4,5,6,7,8-octahydroacridine-N(10)-oxides is evaluated against 12 bacterial and fungal strains, for their microbicidal and anti-pathogenic features. The largest spectrum of the antibacterial activity is evidenced for the nitro- (2b) and hydroxy- (5b) N-oxides, foll...
We have fabricated efficient blue organic light-emitting devices (OLEDs) with 4,4′-bis (9-ethyl-3carbazovinylene)-1,1′-biphenyl(BCzVBi) as the fluorescent emitter doped into 4,4′-bis(carbazol-9-yl)biphenyl(CBP) and 1,3,5-Tris(1-phenyl-1H-benzimidazol-2-yl)benzene (TPBi), respectively, and the...
The biphenyl-based phosphine, 2-diphenylphosphino-2′-methylbiphenyl is an effective ligand for palladium-catalyzed terminal arylation of 1,1-disubstituted olefins with aryl bromides in DMF and K2CO3 as base. The yields of products are independent of the electronic properties of the aryl bromide...
In order to develop phenyl sulfonamides as a novel class of anti-epileptic drugs (AED) for both general and partial seizure, we initiated in vivo screening of our chemical library in the mice MES and sc-PTZ models and found compounds 1 and 2 as lead compounds. Optimization of 1 and 2 led to the ...
To explore the feasibility of extracting aromatic acid products from oxidizing coal, two aromatic acids, trimellitic and [1,1′-biphenyl]-2,2′-dicarboxylic acid, were selected as the solutes, and the extraction equilibrium of the acids were studied with 1-octanol, 50% tributyl phosphate (TBP) i...
A convenient synthesis of 2,2′,6,6′-tetraphosphanylbiphenyls 1 by lithium/halide exchange and electrophilic reaction with chlorophosphanes or palladium catalyzed phosphanylation is presented. Three examples of 2,2′,6,6′-tetraphosphanylbiphenyls 1b-d were investigated by single crystal X-ray ...
The knowledge of solubility and dissolution thermodynamics for 2,2′,4,4′,6,6′-hexanitro-1,1′-biphenyl (HNBP) and 2,2′,2″,4,4′,4″,6,6′,6″-Nonanitro-1,1’:3′,1″-terphenyl (NONA) in different solvents is not only significant for its crystallization and further theoretical studies, but a...
(E)-N-([1,1'-biphenyl]-2-yl)-1-mesitylmethanimine (imine a) and two structural cyclopalladated isomers of imine a, which contained a six-membered metallacycle and an aliphatic and an aromatic metallated carbon of formula [Pd{CH2-3,5-Me2-6-(CH=N-C6H4-2′-C6H5)C6H2}Br(PPh3)] (3a-endo) and [Pd...
The mechanisms conferring to the trans-stilbene derivatives their well known important biological properties are not yet completely clear; then, it is reasonable to suppose that their conformational equilibrium could play some kind of role (as found for many other molecules of pharmacological in...
The data presented in this article are related to the research article entitled “Phase stability and transport characteristics of (ZrO2)1-x(Sc2O3)x(СeO2)y and (ZrO2)1-x-y-z(Sc2O3)x(СeO2)y(Y2O3)z solid solution crystals” https://www.sciencedirect.com/science/article/pii/S2352340917302329 [1]....
AimsThe present study aims to investigate the protective effect and underlying mechanism of Z-Guggulsterone (Z-GS), an active component from myrrh, on glucocorticoid-induced osteoporosis (GIO).
The capacity of redox and the separation efficiency of electron-hole pairs are important indexes for evaluating the performance of photocatalyst. Herein, a novel Z-scheme Ag/g-C3N4-Ag-Ag3PO4 (1 1 0) photocatalyst is prepared by photo-assisted isoelectric point way. The prepared samples are chara...
1-Methyl-4-phenylpyridinium (ion) (MPP+) is the ultimate neurotoxic agent formed by metabolism of MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) involving monoamine oxidase-B (MAO-B). MPP+ induces parkinsonism. The MPP+ production is thought to occur in astrocytes; MPP+ is then taken up by ...
BackgroundTetranectin is a secreted homotrimeric protein belonging to the C-type lectin family. Our previous studies found that tetranectin was not only related to, but also played a protective role in, Parkinson disease. In this study, we aim to illustrate the molecular mechanism of the secrete...
Cigarette smoke can affect female reproductive health by causing follicle destruction and oocyte dysfunction. Third-hand smoke has received increasing attention as a public health issue. However, the effects of third-hand smoke on the female reproductive system, particularly the ovaries, remain ...
Diketene is an ideal molecule for use in many organic transformations, since it possesses electrophilic and nucleophilic sites which react with numerous functional groups. Diketene is mostly used as the common starting material for structurally diverse mono-, spiro-, and fused six-membered heter...
The 1-hydro-2,6-dimethyl-3,5-dicyanopyridinyl radical (HDCP·) has been identified by electron spin resonance spectroscopy (ESR) in solution at room temperature as an intermediate during both the 280–300 nm photoreduction of 2,6-dimethyl-3,5-dicyanopyridine (DCP) in 2-propanol and the 270–300 ...
The etherification of chitosan dissolved in aqueous LiOH/KOH/urea solutions was conducted for the first time. The structure and solution properties of the chitosan ethers were characterized using FT-IR, NMR, SEC-LLS, elemental analysis, and ζ-potential measurement. Chitosan ethers with differen...
