Abstract
We consider the Porod-Debye law as a powerful tool for detecting biopolymer flexibility in SAS experiments. We show that the Porod-Debye region fundamentally describes the nature of the scattering intensity decay by capturing the information needed for distinguishing between folded and flexible part...

Journal of Antibiotics (64)6 2011
Abstract
Benzoxacystol, a new 1,4-benzoxazine-type metabolite, was produced by strain NTK 935, a marine member of the Streptomyces griseus 16S rRNA clade, isolated from deep-sea sediment collected from the Canary Basin. The structure of benzoxacystol was determined by mass spectrometry, NMR experiments and X-...

Abstract
We reevaluated the structure of the different SGL acyl (di-, tri-, and tetra-acylated) forms of the reference strain Mycobacterium tuberculosis H37Rv, as well as those produced by the mmpL8 knockout strains previously described to intracellularly accumulate di-acylated SGL. We report here the identi...

Abstract
The advent of metabonomics has seen a proliferation of biofluid profiling studies of patients with hepatocellular carcinoma. The majority of these studies have been conducted in single indigenous populations making the widespread applicability of candidate metabolite biomarkers difficult. Presented h...

Abstract
We examined pharmacological activities of these compounds in vitro (binding studies) and in vivo (MES test). Pharmacological evaluations revealed one of the compounds, 5a, to be a good lead, exhibiting moderate binding at NMDA receptors (IC(50) = 7.86 μM; K(i) = 5.28 μM), MES neuroprotection activ...

Innate Immunity (17)2 2011
Abstract
We present a structural and genetic analysis of the Y. pseudotuberculosis serotype O:1c OPS. Our results showed that this OPS has the same backbone as Y. pseudotuberculosis O:2b, but with a 3,6-dideoxy-D-ribo-hexofuranose (paratofuranose, Parf) side-branch instead of a 3,6-dideoxy-D-xylo-hexopyranos...

Ceska a Slovenska farmacie : casopis Ceske farmaceuticke spolecnosti a Slovenske farmaceuticke spolecnosti (60)2 2011
Abstract
The present paper deals with a complex spectral and physicochemical evaluation of mono[{3-[4-(2-etoxyetoxy)-benzoyloxy]-2-hydroxypropyl}-isopropylammonium]fumarate, a potential ultrashort acting beta1-blocker. The identity of the substance under study (labelled as UPB-1) was confirmed by 1H- and 13C-...

Biopolymers (95)8 2011
Abstract
We present an overview of the effect that structural diversity intrinsic to protein ensembles has on scattering data. We then demonstrate the observation of these effects in scattering from four molecular systems; myoglobin; ubiquitin; alcohol dehydrogenase; and HIV protease; and demonstrate the mod...

Abstract
A six-coordinate oxovanadium(V) thiolate complex and an eight-coordinate non-oxovanadium thiolate complex, [PPh(4)][VO(PS3'')(OCH(3))] (1) and [NEt(4)][V(PS3'')(2)] (2) (PS3'' = P(C(6)H(3)-3-Me(3)Si-2-S)(3)(3-)), respectively, have been isolated and structurally characterized. The former belongs to a...

Abstract
The reaction of the phosphonium alkylidene [(H(2)IMes)RuCl(2)═CHP(Cy)(3))](+) BF(4)(-) with propene, 1-butene, and 1-hexene at -45 °C affords various substituted, metathesis-active ruthenacycles. These metallacycles were found to equilibrate over extended reaction times in response to decreases in...

Abstract
We have explored a new class of organometallic "piano-stool" Ru(II) and Os(II) arene anticancer complexes of the type [(η(6)-arene)Ru/Os(XY)Cl](+). Here XY is, for example, ethylenediamine (en), and the arene ligand can take many forms, including tetrahydroanthracene, biphenyl, or p-cymene. Arene-n...

Abstract
Chronic marijuana (MRJ) use is associated with altered cognition and mood state, altered brain metabolites, and functional and structural brain changes. The objective of this study was to apply proton magnetic resonance spectroscopic imaging (MRSI) to compare proton metabolite levels in 15 young men...

Abstract
The homo-Reformatsky reaction, in which a metal homoenolate of an ester is added to an aldehyde, was adapted to produce γ-lactones from unsaturated, enolizable aldehydes. By use of titanium homoenolate, 11 different γ-lactones were synthesized in one step with moderate to good yields from readily a...

Feeding deterrents from Aconitum episcopale roots against the red flour beetle, Tribolium castaneum.
Abstract
The screening for insecticidal principles from several Chinese medicinal herbs showed that the ethanol extract of Aconitum episcopale roots possessed significant feeding deterrence against the red flour beetle, Tribolium castaneum . From the ethanol extract, six feeding deterrents were isolated by bi...

Abstract
We have previously observed that VIP-G (glycine-extended VIP) is unstructured in solution, as evidenced by the limited NMR chemical shift dispersion. In this study, we determined the three-dimensional structures of VIP-G in two distinct membrane-mimicking environments. Although these are basically s...

Abstract
Consumption of improperly ripened ackee ( Blighia sapida K.D. Koenig) often results in fatalities. The causal toxin, hypoglycin A, decreases in the edible arilli upon maturity; regulation of hypoglycin A in the arilli is thus critical. Hypoglycin B, also toxic, is confined to the seeds. Hypoglycins A...

Abstract
Potatoes, tomatoes, and aubergines are all species of the Solanum genus and contain a vast array of secondary metabolites including calystegine alkaloids, phenolic compounds, lectins, and glycoalkaloids. Glycoalkaloids have been the subject of many literature papers, occur widely in the human diet, a...

Abstract
We show that the pH-driven assembly-disassembly natural process that occurs in apoferritin protein is effective for the encapsulation of maghemite nanoparticles of different sizes: 4 and 6 nm. In a second step, we demonstrate that the presence of functional amine groups in the outer shell of apoferr...
