Simple Synthesis of a Heterocyclophane Exhibiting Anti-c-Met Activity by Acting as a Hatch Blocking Access to the Active Site*.

A simple approach to the synthesis of heterocyclophane consisting of two 4,4'-bithiazoles has been developed in mild conditions. The heterocyclophane with two short chains was conveniently prepared by Hantzsch thiazoles synthesis using the reaction of 3-tert-butoxycarbonyl-3-azapentanethiocarboxamide with 1,4-dibromobutane-2,3-dione in methanol under reflux for only 15 min. Amino groups at the linkers of this heterocyclophane can be functionalized to give acylated and carbamate derivatives.

Ferulic acid esters and weight-loss promoting effects in rats.

We previously fed rats with an ester (90 ppm in a powdered AIN93G diet) synthesized from gallic acid and 1,2-dioleoyl glycerol and found that it promoted weight loss more effectively than either octyl gallate or gallic acid. Here, we esterified ferulic acid (FerA) with oleic acid, monooleoyl glycerol and dioleoyl glycerol to obtain oleoyl ferulic acid (FO), feruloyl monooleoyl glycerol (FMO) and feruloyl dioleoyl glycerol (FDO) esters, respectively. A mixture of AIN93G and 90 ppm of each ester and FerA was fed to 10-week-old male Wistar rats for 12 weeks.

Assays of PCB congeners and organochlorine insecticides with the transgenic Arabidopsis and tobacco plants carrying recombinant guinea pig AhR and GUS reporter genes.

Certain congeners of polychlorinated biphenyls (PCBs) and organochlorine insecticides are ligands of aryl hydrocarbon receptors (AhRs) in animals. A recombinant guinea pig (g) AhR, XgDV, was constructed by fusing the ligand-binding domain of gAhR, the DNA-binding domain of LexA, and the transactivating domain of VP16. Then, the expression unit of β-glucuronidase (GUS) reporter gene regulated by XgDV was introduced into Arabidopsis and tobacco plants.

Gallic acid glycerol ester promotes weight-loss in rats.

Lifestyle-related diseases arise from obesity in 30 - 60% of cases. In recent years, food functions controlling the nutritional physiology of lipids have been a focus of disease prevention. Animal feeding experiments have revealed that esters made from gallic acid (GA) and (-)-epigallo-catechin (EGC) or linoleyl alcohol are more effective in weight-loss promotion and metabolic syndrome management than are intact GA and EGC.

Visualization and structural analysis of the bacterial magnetic organelle magnetosome using atomic force microscopy.

The unique ability of magnetotactic bacteria to navigate along a geomagnetic field is accomplished with the help of prokaryotic organelles, magnetosomes. The magnetosomes have well-ordered chain-like structures, comprising membrane-enveloped, nano-sized magnetic crystals, and various types of specifically associated proteins. In this study, we applied atomic force microscopy (AFM) to investigate the spatial configuration of isolated magnetosomes from Magnetospirillum magneticum AMB-1 in near-native buffer conditions.

Effect of moderate salinity stress treatment on the stimulation of proline uptake and growth in Escherichia coli CSH4 and its mutants under high salinity.

Activity of proline uptake in Escherichia coli CSH4 was inhibited in the presence of 1 M NaCl, while it was recovered if the cells were incubated at 30 degrees C for 1 h in a moderate salinity stress (MSS) solution which consists of Davis minimal medium with 5 mM proline and 0.5 M NaCl. Then, an attempt was made to examine whether MSS treatment is also effective on the activity restoration of proline uptake and growth under high salinity for E.

Bioassay of estrogenic compounds in transgenic Arabidopsis plants carrying a recombinant human estrogen receptor gene and a GFP reporter gene.

Transgenic Arabidopsis plants carrying a recombinant human estrogen receptor gene and a green fluorescent protein reporter gene were used to bioassay estrogenic compounds. We constructed four recombinant human estrogen receptor genes by combining the DNA-binding domain of LexA, a synthetic nuclear localization signal, a ligand-binding domain of the human estrogen receptor, and a transactivation domain of VP16 in different orders; the XEV plants were the most sensitive, and were able to detect 0.001 ng ml(-1) of 17ss-estradiol (E(2)).

Social rank modulates brain arginine vasotocin immunoreactivity in false clown anemonefish (Amphiprion ocellaris).

The brain nanopeptide arginine vasotocin (AVT) and its mammalian homolog arginine vasopressin are involved in the regulation of social and reproductive behavior. We investigated the relationship between social rank formation and the brain AVT system in the false clown anemonefish (Amphiprion ocellaris), which forms a social rank that leads to sex differentiation in higher-ranked individuals. Tanks of three sexually immature fish were kept for 90 days and each fish's behavior was observed once a month.

Social environment and sex differentiation in the false clown anemonefish, Amphiprion ocellaris.

Plasticity in sex differentiation is known to be common in teleost fishes. Anemonefishes are protandrous; females are the largest and dominant members of social groups, displaying frequent aggressive behavior towards other members of groups. The second-ranked individuals become males and others remain as non-reproductive individuals.
