Analysis of an antimicrobial extract prepared from culture broth of the marine-derived actinomycete Streptomyces sp. G278 led to the isolation of ten compounds, 1-10. Two compounds, 2,5-Bis(5-tert-butyl-2-benzoxazolyl)thiophene (1), and 3-hydroxyl-2-methylpyridine (2) were isolated from a natural source for the first time. The structures of the isolated compounds were established by their spectral data analysis, including mass spectrometry, 1D-NMR, 2D-NMR, and X-ray crystallographic analysis in case of compound 3. All isolated compounds were evaluated for their antimicrobial activity against a panel of clinically significant microorganisms. Compounds 1 and 3 selectively inhibited Enterococcus faecalis (MIC: 256 mug/mL). Compound 2 was found to have antibacterial and antifungal activity against Escherichia coli (MIC: 64 mug/mL), Salmonella enterica (MIC: 256 mug/mL), Staphylococcus aureus (MIC: 256 mug/mL), Enterococcus faecalis (MIC: 256 mug/mL), and Candida albicans (MIC: 64 mug/mL). Except for compounds 9 and 10, the other known metabolites (4-8) also exhibited antimicrobial activity.

o- and/or p-naphthoquinone methides (NQMs) can be selectively prepared by the ring opening of 1-(siloxymethyl)-1,4-epoxy-1,4-dihydronaphthalene derivatives based on a substituent effect at the 4 position of the substrates. The 4-alkyl- or silyl-substituted 1-(siloxymethyl)-1,4-epoxy-1,4-dihydronaphthalene was transformed to o-NQM (1-naphthoquinone-2-methide), which underwent Friedel-Crafts 1,4-addition of the alpha,beta-unsaturated carbonyl moiety to provide the 2-benzyl-1-naphthol as the biarylmethane and [4 + 2]-cycloaddition with a dienophile to give the fused heterocyclic arene. Meanwhile, the 4-unsubstituted 1-(siloxymethyl)-1,4-epoxy-1,4-dihydronaphthalene could be converted to the corresponding 4-benzyl-1-naphthol by the Friedel-Crafts 1,6-addition of p-NQM (1-naphthoquinone-4-methide) generated by the site-selective ring opening of the 1,4-epoxy moiety. Furthermore, the 4-(siloxymethyl)-(1,4-bis(siloxymethyl))-1,4-epoxy-1,4-dihydronaphthalene was transformed into a 2,4-bisbenzyl-1-naphthol or pentacyclic derivative via both the o- and p-NQM intermediates.

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.

An alternative method for improving the production of habanero chili is the tissue culture technique; however, the gelling agent, the high salt and sucrose concentrations used in the culture media raise production costs and limit the adaptation of the regenerated plants to greenhouse or field conditions. In this study, the effect of the substrates perlite-coconut fiber, coconut fiber-volcanic rock, vermiculite-perlite, and perlite-volcanic rock in conjunction with various culture media in in vitro plant regeneration from embryos was evaluated. The differentiation of adventitious shoots on substrates was scarcely observed or non-existent. Inducing the formation of shoots on agar and their development and rooting on substrates allowed to obtain plants. The greatest number of shoots per explant was observed on media with Murashige and Skoog salts (MS) 100%, 15 or 30 g/L sucrose, 4 mg/L benzylaminopurine, 0.3 mg/L indolacetic acid, and vermiculite-perlite or agar. The highest rooting percentages were obtained for treatments that consisted of MS 50%, MS 100% or Arnon and Hoagland salts (H), 15 g/L sucrose, 1 mg/L indole-3-butyric acid, and perlite-volcanic rock, vermiculite-perlite or agar (88-90%). The highest survival rate, number of leaves, plant length, and stem diameter during acclimation were obtained with media containing MS 50%, MS 100% or H salts, 15 g/L sucrose, 1 mg/L indole-3-butyric acid, and vermiculite-perlite, perlite-volcanic-rock or agar. It is feasible to use culture media less concentrated and substrates for the micropropagation of the habanero chili. The protocol developed significantly reduced production costs.

Dendrobium aphyllum is an edible plant that is used as a functional food to improve health. We previously examined peptides and polysaccharides extracted from Dendrobium aphyllum; however, we did not investigate D. aphyllum?s alkaloid compounds and their functions. In this study, we detail the composition of alkaloids from Dendrobium aphyllum (DAA), including 2alpha, 3beta-dihydroxy nortropane, 1-methyl-2-[(4Z,7Z)-4,7-tridecadienyl]-4(1H)-quinolone and maokonine, which were first identified by UPLC-MS analysis. Furthermore, the anti-inflammatory activity of DAA on LPS-induced RAW 264.7 macrophages was examined. DAA treatment inhibited LPS-induced NO production and decreased (P < 0.05) IL-1, IL-6, TNF-alpha and PGE2 secretion in the RAW 264.7 macrophages. DAA treatment also inhibited COX-2 and iNOS mRNA expression in a dose-dependent manner, indicating that these compounds can attenuate the synthesis of the above-mentioned molecules at the transcriptional level, tentatively confirming their anti-inflammatory effect.

2-Iodo-5-nitrothiophene, 2,-bromo-5-cyanothiophene, 2-iodo-5-cyanothiophene, and 4-iodo nitrobenzene were studied by steady state and pulsed methods and by semi-empirical quantum-mechanical computations. The quantum yields for the direct and sensitized photoarylation of these haloromatics following the photocleavage of the carbon-halogen bond were measured in benzene. The transient species originated by direct and sensitized laser excitation were examined by nanosecond laser flash photolysis in benzene and methylcyclohexane. The transients were characterized in terms of absorption spectra and decay lifetimes, and the triplet states were also characterized by phosphorescence measurements in rigid matrices at low temperature. The quenching rate constants of the triplet states and the quantum yields for singlet oxygen production were determined in methylcyclohexane. Findings obtained with sensitizers of various triplet energy showed that an upper triplet state is involved in the photocleaveage of the carbon-halogen bond.
