-Sitosterol, stigmasterol, cardamomin (1), chalconaringenin 2-O-methyl ether (2), alpinetin (3), and naringenin 5-O-methyl ether (4) were isolated from the MeOH extract of Alpinia conchigera Griff. (Zingiberaceae). Their structures were determined on the basis of spectroscopic analyses. The antimicrobial and free radical scavenging activities of the isolates 1-4 were evaluated in correlation with those of the soluble fractions.

Immediately after the first drafts of the human genome sequence were reported almost a decade ago, the importance of genomics and functional genomics studies became well recognized across the broad disciplines of biological sciences research.

Forty-five years ago, agricultural and pharmaceutical chemistry appeared to be following divergent paths. On the agricultural scene industrial companies were concentrating on the synthesis of various classes of compounds and when a successful chemical candidate was discovered, there was a good deal of joy among the synthetic chemists. We were told that as a result of chemistry life would be better and, indeed, it was. Armed with synthetic agrochemicals, the American farmer became the envy of the world....

Polysaccharide fractions isolated from Lentinula edodes fruitbodies and mycelium demonstrate strong immunomodulating, antioxidant and anticancer activity. We hypothesized, that polysaccharide fractions enriched in selenium would possess higher biological activity than non-enriched fractions, currently used to treat cancer. The first goal of this study was to isolate selenium (Se)-enriched polysaccharide fractions of different molecular weight from L. edodes mycelium cultivated under the submerged conditions in Se-enriched medium, and to investigate their monosaccharide composition....

Of the 600+ known proteases identified to date in mammals, a significant percentage is involved or implicated in pathogenic and cancer processes. The dipeptidyl peptidase IV (DPIV) gene family, comprising four enzyme members [DPIV (EC 3.4.14.5), fibroblast activation protein, DP8 and DP9] and two nonenzyme members [DP6 (DPL1) and DP10 (DPL2)], are inter-esting in this regard because of their multiple diverse functions,

In 1960, a trypsin-like activity was found in mast cells [Glenner GG & Cohen LA (1960)Nature185, 846–847] and this activity is now commonly referred to as ‘tryptase’. Over the years, much knowledge about mast cell tryptase has been gathered, and a recent (18 January 2006) PubMed search for the keywords ‘tryptase + mast cell*’ retrieved 1661 articles.

Oligomerization into multimeric complexes is a prerequisite for the chaperone function of almost all a-crystallin type heat shock proteins (a-Hsp), but the molecular details of complex assembly are poorly understood. The a-Hsp proteins from Bradyrhizobium japonicum are suitable bacterial models for structure-function studies of these ubiquitous stress proteins. They fall into two distinct classes, A and B, display chaperone activity in vitro and form oligomers of  24 subunits.

Glutaminase from Micrococcus luteusK-3 [Micrococcusglutaminase (Mglu); 456 amino acid residues (aa); 48 kDa] is a salt-tolerant enzyme. Our previous study determined the structure of its major 42-kDa fragment. Here, using new crystallization conditions, we determined the structures of the intact enzyme in the presence and absence of its product l-glutamate and its activator Tris, which activates the enzyme by sixfold.

Realistic quantitative models require data from many laboratories. There-fore, standardization of experimental systems and assay conditions is crucial. Moreover, standards should be representative of thein vivoconditions. How-ever, most often, enzyme–kinetic parameters are measured under assay con-ditions that yield the maximum activity of each enzyme.

Activation of peroxisome proliferator-activated receptor (PPAR)-c sup-presses proliferation of rat pulmonary artery smooth muscle cells (PASMCs), and therefore ameliorates the development of pulmonary hypertension in animal models. However, the molecular mechanisms under-lying this effect remain largely unknown.

Lipooligosaccharide (LOS), a major component of the outer membrane of Moraxella catarrhalis, consists of two major moieties: a lipid A and a core oligosaccharide (OS). The core OS can be dissected into a linker and three OS chains.
