Synthesis of 2,5-dihydroxy-3-(indol-3-yl)benzoquinones by acid-catalyzed condensation of indoles with 2,5-dichlorobenzoquinone

Three methods for the conjugate addition of indoles to 2,5-dichlorobenzoquinone have been developed. A wide variety of indoles substituted with halogen, alkyl, alkoxy, and aryl groups participate in anaerobic condensation reactions promoted by HCl, H2SO4, or CH3CO2H. The hydroquinone product is partially oxidized by excess dichlorobenzoquinone and fully converted to the 2,5-dichloro-3-(indol-3-yl)benzoquinone targets by DDQ or Ag2CO3 oxidation. 2,5-Dihydroxy- 3-(indol-3-yl)benzoquinones can be obtained from the dichlorides by alkaline hydrolysis. The rotational characteristics of the biaryl bond created in these reactions have been examined by theoretical and spectroscopic methods.

Synthesis and antibacterial in vitro activity of novel analogues of nematophin

The synthesis and in vitro antibacterial activity of new derivatives and analogues of nematophin are described. It was shown that the unsubstituted amide NH-group is essential for bioactivity. Alkyl- or aryl-substitution at the 1-position results in a distinct increase of antibacterial activity. Addition of protein (blood or serum) to the culture media reduces the inhibitory activity on bacteria.

Halogenated indole-3-acetic acids as oxidatively activated prodrugs with potential for targeted cancer therapy

Substituted indole-3-acetic acid (IAA) derivatives, plant auxins with potential for use as prodrugs in enzyme-prodrug directed cancer therapies, were oxidised with horseradish peroxidase (HRP) and toxicity against V79 Chinese hamster lung fibroblasts was determined. Rate constants for oxidation by HRP compound I were also measured. Halogenated IAAs were found to be the most cytotoxic, with typical surviving fractions of <10-3 after incubation for 2 h with 100 muM prodrug and HRP.

7-Cyanoindole fluorescence as a local hydration reporter: Application to probe the microheterogeneity of nine water-organic binary mixtures

Considerable efforts have been devoted to the development of spectroscopic probes that are sensitive to water and can be used to monitor, for example, biological and chemical processes involving dehydration or hydration. Continuing this line of research, herein we show that 7-cyanoindole can serve as a sensitive fluorescence probe of hydration as its fluorescence properties, including intensity, peak wavelength and lifetime, depend on the amount of water in nine water-organic solvent mixtures. Our results indicate that 7-cyanoindole is not only able to reveal the underlying microheterogeneity of these binary solvent systems, but also offers distinct advantages. These include: (1) its fluorescence intensity increases more than ten times upon going from a hydrated to a dehydrated environment; (2) its peak wavelength shifts as much as 35 nm upon dehydration; (3) its single-exponential fluorescence decay lifetime increases from 2.0 ns in water to 8-16 ns in water-organic binary mixtures, making it viable to distinguish between differently hydrated environments via fluorescence lifetime measurements; and (4) its absorption spectrum is significantly red-shifted from that of indole, making selective excitation of its fluorescence possible in the presence of naturally occurring amino-acid fluorophores. Moreover, we find that for seven binary mixtures the fluorescence lifetimes of 7-cyanoindole measured at solvent compositions where maximum microheterogeneity occurs correlate linearly with the peak wavenumbers of its fluorescence spectra obtained in the respective pure organic solvents. This suggests that the microheterogeneities of these binary mixtures bear certain similarity, a phenomenon that warrants further investigation.

Durability of polymeric coatings: Effects of natural and artificial weathering

The durability of three commercially available polymeric coatings are investigated using slow positron beam techniques to monitor changes in sub nanometer defects during the degradation process. Doppler broadening energy spectra (DBES) measurements were performed on the slow positron beam at the University of Missouri-Kansas City. Results from UVB-313 artificial weathering are compared to the results for natural weathering for each of the coatings. It is shown that the slow positron beam technique is very successful in detecting the very early stages of coating degradation. In addition, the depth profile of the degradation process provides important information on the durability of the coatings and the kinetics of the degradation as a function of the depth from the surface. The artificial weathering technique is discussed as a predictor of the durability to natural weathering. It is shown that for each of the weathering systems differences are observed for each of the coatings. The loss of free volume during the degradation process is interpreted as being due to photo-oxidation of the polymer, with a net result of an increase in the crosslink density of the polymer.

Ni2O3-around-Pd hybrid on graphene oxide: An efficient catalyst for ligand-free Suzuki-Miyaura coupling reaction

Ni2O3-around-Pd hybrid can be fabricated on graphene oxide (Pd-Ni/RGO) by a simple one-pot wet chemical route. These isolated Pd clusters showed significantly improved performance for Suzuki coupling reaction compared to that of pure Pd/RGO, Ni2O3/RGO, popularly reported Pd/AC, as well as homogeneous PdCl2 and PdCl 2(PPh3)2. Characterizations disclosed that Ni2O3 plays multiple roles in exfoliating graphene sheets, mediating the size as well as stability of Pd clusters. Pd-Ni/RGO dispersed homogeneously in the aqueous reaction mixture, exhibited high enrichment towards reactants as well as extremely high activity and stability for the Suzuki coupling reaction. The best turnover frequencies of all Pd atoms reached 38,750 h-1 at 80 C for bromobenzene coupling. It was concluded that the intimate interaction between Ni2O3 nanoparticles and Pd clusters appears to be beneficial for activating the Pd surface for the catalytic cycle.
