An Alternative Standard forTrolox‐Equivalent Antioxidant‐Capacity Estimation Based on Thiol Antioxidants. Comparative 2,2′‐Azinobis[3‐ethylbenzothiazoline‐6‐sulfonic Acid] Decolorization and Rotational Viscometry Study Regarding Hyaluronan Degradation
Authors: Hrabárová Eva , Valachová Katarína , Rapta Peter , Šoltés Ladislav 
Published: September 2010

AbstractComparison of the effectiveness of antioxidant activity of three thiol compounds,D‐penicillamine, reducedL‐glutathione, and 1,4‐dithioerythritol, expressed as a radical‐scavenging capacity based on the two independent methods, namely a decolorization 2,2′‐azinobis[3‐ethylbenzothiazoline‐6‐sulfonic acid] assay and a rotational viscometry, is reported. Particular concern was focused on the testing of potential free‐radical scavenging effects of thiols against hyaluronan degradation, induced by hydroxyl radicals. A promising, solvent‐independent, antioxidative function of 1,4‐dithioerythritol, comparable to that of a standard compound,Trolox®, was confirmed by the 2,2′‐azinobis[3‐ethylbenzothiazoline‐6‐sulfonic acid] assay. The new potential antioxidant 1,4‐dithioerythritol exhibited very good solubility in a variety of solvents (e.g., H2O, EtOH, and DMSO) and could be widely accepted and used as an effective antioxidant standard instead of a routinely usedTrolox®on 2,2′‐azinobis[3‐ethylbenzothiazoline‐6‐sulfonic acid] assay.
Volatile Composition Screening of Salix spp. Nectar Honey: Benzenecarboxylic Acids, Norisoprenoids, Terpenes, and Others
Authors: Jerković Igor , Marijanović Zvonimir 
Published: September 2010

AbstractSalix spp. nectar honey volatiles of Croatian origin were analyzed by headspace solid‐phase microextraction (HS‐SPME) and ultrasonic solvent extraction (USE), followed by gas chromatography and mass spectrometry (GC, GC/MS). Isolated volatiles were found in the honey headspace and extracts with almost exclusive distribution of several abundant compounds (e.g., phenylacetic acid, pinocembrin, 8‐hydroxy‐4,7‐dimethylcoumarin, and 3‐hydroxy‐trans‐β‐damascone in the extracts, or safranal and lilac alcohols in the headspace). Comparison with Croatian Salix spp. honeydew honey revealed similarities regarding distribution of important shikimate pathway derivatives (e.g., high percentage of phenylacetic acid) and several norisoprenoids (α‐isophorone and 4‐oxoisophorone). On the other hand, distinct features of this honey were occurrence of compounds such as pinocembrin, 8‐hydroxy‐4,7‐dimethylcoumarin, phenylacetonitrile, norisoprenoids (major ones: 3‐hydroxy‐trans‐β‐damascenone and trans‐β‐damascone), more pronounced variability of linalool‐derived compounds, as well as the abundance of 3‐methylpropanoic acid, 3‐methylbutanoic acid, 2‐methylpentanoic acid, and 3‐methylpentan‐1‐ol.

Published: September 2010

AbstractPhytotoxic microbial metabolites produced by certain phytopathogenic fungi and bacteria, and a group of phytotoxic plant metabolites including Amaryllidacea alkaloids and some derivatives of these compounds were evaluated for algicide, bactericide, insecticide, fungicide, and herbicide activities in order to discover natural compounds for potential use in the management and control of several important agricultural and household structural pests. Among the various compounds evaluated: i) ophiobolin A was found to be the most promising for potential use as a selective algicide; ii) ungeremine was discovered to be bactericidal against certain species of fish pathogenic bacteria; iii) cycasin caused significant mortality in termites; iv) cavoxin, ophiobolin A, and sphaeropsidin A were most active towards species of plant pathogenic fungi; and v) lycorine and some of its analogues (1‐O‐acetyllycorine and lycorine chlorohydrate) were highly phytotoxic in the herbicide bioassay. Our results further demonstrated that plants and microbes can provide a diverse and natural source of compounds with potential use as pesticides.
Anti‐Tumor‐Initiating Effects of Spiro‐biflavonoids from Abies sachalinensis
Authors: Wada Shun‐ichi , Hitomi Teppei , Tokuda Harukuni , Tanaka Reiko 
Published: September 2010

AbstractCancer chemoprevention, the prevention of cancer by ingestion of chemical agents that reduce the risk of carcinogenesis, is one of the potent ways to reduce morbidity and mortality. We have been searching for cancer chemopreventive agents from the leaves and barks of coniferous trees that have been treated as waste in the forestry industry. We have previously reported the isolation of spiro‐biflavonoids, named as abiesinols, and a neolignan from the MeOH extract of the bark of Abies sachalinensis. These compounds were tested for their inhibitory effects on the activation of (±)‐(E)‐methyl‐2‐[(E)‐hydroxyimino]‐5‐nitro‐6‐methoxyhex‐3‐enamide (NOR 1), a nitric oxide (NO) donor, as a primary screening test for anti‐tumor initiators. All compounds tested exhibited potent inhibitory effects on NOR 1 activation. Furthermore, abiesinol A, bearing a spiro‐biflavonoid skeleton, showed remarkable anti‐tumor‐initiating activity in the in vivo two‐stage mouse skin carcinogenesis test using peroxynitrite (ONOO−; PN) as the initiator and 12‐O‐tetradecanoylphorbol‐13‐acetate (TPA) as the promoter.
The Biosynthesis of Branched Dialkylpyrazines in Myxobacteria
Authors: Nawrath Thorben , Dickschat Jeroen S. , Kunze Brigitte , Schulz Stefan 
Published: September 2010

AbstractThe biosynthesis of the volatiles 2,5‐ and 2,6‐diisopropylpyrazine (2 and 3, resp.) released by the myxobacteria Nannocystis exedens subsp. cinnabarina (Na c29) and Chondromyces crocatus (strains Cm c2 and Cm c5) was studied. Isotopically labeled precursors and proposed pathway intermediates were fed to agar plate cultures of the myxobacteria. Subsequently, the volatiles were collected by use of a closed loop stripping apparatus (CLSA), and incorporation into the pyrazines was followed by GC/MS analysis. [2H8]Valine was smoothly incorporated into both pyrazines clearly establishing their origin from the amino acid pool. The cyclic dipeptide valine anhydride (16) – a potential intermediate on the biosynthetic pathway to branched dialkylpyrazines – was synthesized containing 2H1 labels in specific positions. Feeding of [2H16]‐16 and [2H12]‐16 in both valine subunits mainly resulted in the formation of pyrazines derived from only one labeled amino acid, whereas only traces of the expected pyrazines with two labeled subunits were found. To investigate the origin of nitrogen in the pyrazines, a feeding experiment with [15N]valine was performed, resulting in the incorporation of the 15N label. The results contradict a biosynthetic pathway via cyclic dipeptides, but rather point to a pathway on which valine is reduced to valine aldehyde. Its dimerization to 2,5‐diisopropyldihydropyrazine 36 and subsequent oxidation results in 2. The proposed biosynthetic pathway neatly fits the results of earlier labeling studies and also explains the formation of the regioisomer 2,6‐diisopropylpyrazine 3 by isomerization during the first condensation step of two molecules valine aldehyde. A general biosynthetic pathway to different classes of pyrazines is presented.
2‐Azapurine Nucleosides: Synthesis, Properties, and Base Pairing of Oligonucleotides
Authors: Budow Simone , Seela Frank 
Published: September 2010

AbstractThis review deals with 2‐azapurine (imidazo[4,5‐d] [1,2,3]triazine) nucleosides and closely related analogs. Different routes are described to yield the desired target compounds, including a sequence of ring‐opening and ring‐closure reactions performed on purine nucleosides or direct glycosylation of a 2‐azapurine nucleobase with a sugar halide. Further, physical and spectroscopic properties of 2‐azapurine nucleosides are discussed, including fluorescence, 13C‐NMR data, single‐crystal X‐ray analyses, and conformation studies on selected compounds; new biological data are presented. The second part of this review is dedicated to oligonucleotides containing 2‐azapurines, including building‐block (phosphoramidite) preparation and their use in solid‐phase oligonucleotide synthesis. Base‐pairing properties of 2‐azapurine nucleosides as surrogates of canonical constituents of DNA were evaluated.

Authors: Nawrath Thorben , Gerth Klaus , Müller Rolf , Schulz Stefan 
Published: September 2010

AbstractThe analysis of the volatiles released by the novel bacterial isolate Chitinophaga Fx7914 revealed the presence of ca. 200 compounds including different methyl esters. These esters comprise monomethyl‐ and dimethyl‐branched, saturated, and unsaturated fatty acid methyl esters that have not been described as bacterial volatiles before. More than 30 esters of medium C‐chain length were identified, which belong to five main classes, methyl (S)‐2‐methylalkanoates (class A), methyl (S)‐2,(ω−1)‐dimethylalkanoates (class B), methyl 2,(ω−2)‐dimethylalkanoates (class C), methyl (E)‐2‐methylalk‐2‐enoates (class D), and methyl (E)‐2,(ω−1)‐dimethylalk‐2‐enoates (class E). The structures of the compounds were verified by GC/MS analysis and synthesis of the target compounds as methyl (S)‐2‐methyloctanoate (28), methyl (S)‐2,7‐dimethyloctanoate ((S)‐43), methyl 2,6‐dimethyloctanoate (49), methyl (E)‐2‐methylnon‐2‐enoate (20a), and methyl (E)‐2,7‐dimethyloct‐2‐enoate (41a). Furthermore, the natural saturated 2‐methyl‐branched methyl esters showed (S)‐configuration as confirmed by GC/MS experiments using chiral phases. Additionally, the biosynthetic pathway leading to the methyl esters was investigated by feeding experiments with labeled precursors. The Me group at C(2) is introduced by propanoate incorporation, while the methyl ester is formed from the respective carboxylic acid by a methyltransferase using S‐adenosylmethionine (SAM).

AbstractThe cyclic cationic antimicrobial peptide gramicidin S (GS) is an effective topical antibacterial agent that is toxic for human red blood cells (hemolysis). Herein, we present a series of amphiphilic derivatives of GS with either two or four positive charges and characteristics ranging between very polar and very hydrophobic. Screening of this series of peptide derivatives identified a compound that combines effective antibacterial activity with virtually no toxicity within the same concentration range. This peptide acts against both Gram‐negative and Gram‐positive bacteria, including several MRSA strains, and represents an interesting lead for the development of a broadly applicable antibiotic.
