Novel quinoxaline derivatives containing arylaminated aceanthrylene, N,N-diphenylaceanthryleno[2,1-b]quinoxalin-5-amine and N-(naphthalen-2-yl)-N-phenylaceanthryleno[2,1-b]quinoxalin-5-amine, were synthesized as red light emitting materials for use in organic light emitting diodes. The synthesiz...
Two mechanisms for the isomerization of cyclopenta[fg]aceanthrylene to acefluoranthene were revealed. The first pathway occurs via a cyclobutyl intermediate, whereas the second pathway involves a transition state that contains an sp 3-hybridized carbon atom. Both patterns show that the Stone-Wal...
A practical strategy for the synthesis of diazabenz[e]aceanthrylene-based heterocycles is reported. The key step in this approach is a microwave-assisted condensation and cyclisation reaction between an anthranilic acid derivative and a 2′-carbomethoxy substituted N-aryl lactam. The scope of th...
A series of 2,3-diiodoindene were synthesized at first, and 13H-indeno[1,2-l]phenanthrenes were then constructed via a Suzuki coupling reaction and subsequently a Scholl reaction. Structures of synthesized compounds were fully characterized by 1 H NMR, 13 C NMR, and HRMS. Their p...
Summary Angiogenesis is normally a highly regulated process that occurs during development, reproduction, and wound repair. However, angiogenesis can also become a fundamental pathogenic process in cancer and several other diseases. To date, the synthesis of angiogenesis inhibitors has been rese...
Mass spectrometry‐based chemical proteomics is a powerful tool for the target discovery of small molecules. Here, the application of this approach is presented to define the target profile of bio‐inspired synthetic benzo[k,l]xanthene lignans endowed with interesting biological properties. Prot...
Diethoxydimethylsilane was used as a reactant in the laser induced vapour phase reaction for preparing SiC powder. The powder produced under different reactant vapour flow rates was characterized by chemical analysis, TEM, IR, and XRD. Results show that the average particle size of the powder ...
The effect of sodium ion on hydrolysis and condensation of diethoxydimethylsilane (DEDMS) was investigated by i 2 9 Si NMR spectroscopy. Discussed were the possibility of Si O Na linkage through sol-gel processes and the difference of structure for the solutions between with and wi...
Thin a-SiO x C y H z films were deposited from diethoxydimethylsilane in a radio-frequency plasma polymerization process. The plasma deposition and the film properties were characterized with respect to the deposition rate evaluated from scanning electron microscopy obser...
The FTIR and FT-Raman spectra of 2,6-dibromo-4-nitroaniline (2,6-DB4NA) in solid phase and 2-(methylthio)aniline (2-MTA) in liquid phase were measured. The geometry and normal vibrations have been obtained from the density functional theory (DFT) with the B3LYP method employing the 6–31G* basis...
Polymeric prodrugs of N,N-di(2-chloroethyl)-4-phenylenediamine mustard (PDM) were prepared by coupling the drug via an oligopeptide spacer onto poly[N 5 -(2-hydroxyethyl)-l-glutamine] (PHEG). In a first step PDM was linked to the peptide spacer and subsequently the low molecular weight p...
Sulfur mustard (HD) reacts with human serum albumin (HSA) at Cys34 and produces a long-term biomarker of HD exposure. Here, we present a novel, sensitive, and convenient method for quantification of HD exposure by detection of HD-HSA adducts using pronase digestion, benzyl chloroformate (Cbz-Cl)...
Two reaction pathways and their diastereoselectivity-determining steps of the asymmetric desymmetrization of (R)-2-(α-methylbenzyl)amino-1,3-propanediol 1 with 2-chloroethyl chloroformate (CCF) and with N,N′-disuccinimidyl carbonate giving (4S,αR)-4-hydroxymethyl-3-α-methylbenzyl-2-oxazolidi...
