The aromatherapeutical potential of Piper guineense essential oil was investigated in mice via inhalation administration, and the active compounds were identified. An open field test and light/dark transition test were used to evaluate the sedative and anxiolytic activities of this essential oil, respectively. P. guineense essential oil showed significant sedative activity at an effective dose of 4.0×10−5 mg per cage compared to the control group. It also showed potent anxiolytic effect at a dose of 4.0×10−6 mg per cage. The main compounds of P. guineense essential oil were linalool (41.8%) and 3,5-dimethoxytoluene (10.9%). These two main compounds were shown to play a major role in the sedative activity of P. guineense essential oil. These results suggest that inhalation of P. guineense essential oil might induce a mild tranquilizing effect.

The murexide reaction was investigated to clarify the mechanism of the coloration, with caffeine as a model compound. From the reaction mixture of caffeine with hydrogen peroxide and hydrochloric acid, 1-hydroxy-5, 7-dimethyl-2, 4, 6-trioxo-1H, 5H, 7H-oxazolo-[4, 5-d] pyrimidine (yellow oil) (I) and 1, 3, 7-trimethyl-2, 6, 8-trioxo-9-hydroxy-1H, 3H, 7H-xanthine (red powder) (II) were isolated, and these two compounds were shown to be responsible for the murexide reaction of caffeine. Compound I was regarded as a key intermediate, since its purple coloration with dil. ammonia was similar to that of caffeine developed by the murexide reaction. The absorption maximum of II corresponds to that of the red-colored solution obtained from the reaction of caffeine with hydrogen peroxide and hydrochloric acid.

Monoclonal antibodies (MAbs) have been utilized as research tools, as diagnostic reagents, and for antibody medicine. The preparation of MAbs involves laborious processes and normally takes months. Here we describe an ex vivo B cell-based antibody display system called the ADLib (Autonomously Diversifying Library) system, which enables us to select chicken B cell clones producing antibody against antigens of interest in a couple of weeks. The ADLib system is applicable to self- or highly conserved antigens, polysaccharide chains, peptides, and haptens.

Although Polygala tenuifolia WILLD (PT) was classically mentioned as an anti-dementia drug in Chinese and Japanese traditional medicine, basic research showed only enhancement of the cholinergic function. In Alzheimer's disease, neuritic atrophy and synaptic loss occur prior to neuronal death event, and may be the first trigger of the memory impairment. Therefore, we studied effects of Polygala tenuifolia WILLD (PT) on Aβ(25—35)-induced neuronal damage using rat cortical neurons for characterization of activities of PT under Aβ-induced neuronal damage. Treatment with the water extract of PT enhanced axonal length dose-dependently after Aβ(25—35)-induced axonal atrophy. However, dendritic atrophy and synaptic loss induced by Aβ(25—35) were not recovered by treatment with PT extract. In contrast, Aβ(25—35)-induced cell damage was completely inhibited by PT extract. By characterization of PT effects on neuronal morphological plasticity and cell damage, usefulness as well as an insufficiency of PT as an anti-dementia drug was clarified.

To compare the rate of treatment discontinuation due to adverse events for telaprevir-based triple (T/PR) and pegylated interferon-alfa-2b and ribavirin (PR) therapy for the treatment of hepatitis C virus (HCV) infection in patients over the age of 65 years, in Japan.Retrospective analysis of the health data of patients over the age of 65 years treated for a HCV infection genotype 1 using T/PR or PR therapy, from 38 prefectures in Japan. The primary outcome was the rate of treatment discontinuation due to adverse events for T/PR and PR. The secondary outcome was to evaluate the prevalence and type of adverse events during the treatment period that resulted in treatment discontinuation for both therapies. For comparison, the T/PR and PR populations were matched using the propensity score method, and adjusted odds ratios (ORs) for treatment discontinuation calculated by multivariate logistic regression analysis.The study group included 1330 patients, 328 in the T/PR group and 1002 in the PR group. The rate of treatment discontinuation due to adverse events in the matched population was lower for T/PR (19.82%) than PR (35.98%) therapy, (adjusted OR, 0.418; 95% confidence interval, 0.292-0.599; p < 0.01). Malaise was the principal cause of treatment discontinuation in both groups (T/PR, 30.77%, and PR, 42.37%).Using real-world health data of elderly individuals in Japan, we identified a lower rate of treatment discontinuation for T/PR than PR. Our outcomes provide information for a segment of the population that is generally excluded for clinical trials.

Bonding between iron ions and soybean protein (produced by the hydrolysis of soybean meal) in an iron-protein compound, which was prepared by mixing the soybean protein and iron (II) sulfate solution, was studied by infrared spectroscopy and an X-ray powder diffraction method. The oxidation state of the predominant iron ions within the compound was +3,but some Fe (II) ions were also present. In the infrared spectrum of the iron-protein compound, the band ascribable to stretching of the COO^-group was shifted to the higher frequency side by 40 cm^<-1> in comparison with that of the free protein. No evidence was found for the formation of any crystalline iron compounds such as Fe_2O_3,Fe_3O_4 and FeO in the X-ray powder patterns. The possibility of the formation of gel-like compounds of iron (II) and iron (III) such as Fe(OH)_2 and Fe(OH)_3,respectively, was excluded, because the hydrolyzed product of iron (II) is easily oxidized to iron (III) and Fe(OH)_3 transforms, at least partly to Fe_2O_3 or Fe_3O_4 after aging or storing the product in air. Thus, we concluded that the iron ion is bound to the soybean protein molecule through one or more carboxyl groups. Although other coordination sites within the protein molecule could also combine with the iron ions, we could not find evidence for other bondings.

Obesity-related renal diseases have been a worldwide issue. Effective strategy that prevents high fat-diet induced renal damage is of great significance. Resveratrol, a natural plant polyphenol, is famous for its antioxidant activity, cardioprotective effects and anticancer properties. However whether resveratrol can play a role in the treatment of renal diseases is unknown. In this study, we added resveratrol in normal glucose or high glucose medium and provide evidences that resveratrol protects against high-glucose triggered oxidative stress and cell senescence. Moreover, mice were fed with standard diet, standard diet plus resveratrol, high-fat diet or high-fat diet plus resveratrol for 3 months, and results show that resveratrol treatment prevents high-fat diet induced renal pathological damage by activating SIRT1, a key member in the mammalian sirtuin family that response to calorie restriction life-extension method. This research confirms the potential role of resveratrol in the treatment of renal diseases and may provide an effective and convenient method to mimic the beneficial effects of calorie restriction.

The bitterness of 10 different products with ambroxol as active ingredient, the original and nine generics, were evaluated by human gustatory sensation tests in which the tablets were kept in the mouth, with water, at 20 and 37°C. The products all showed different bitterness intensities. The original and some of the generic products had comparatively low bitterness intensities but some of the generic products had comparatively high bitterness intensities. The bitterness intensities of these 10 was found to be significantly correlated with both the disintegration time, as evaluated using the ODT-101 (a recently developed apparatus), and the drug concentration in dissolved medium, as measured in a conventional dissolution test. The bitterness threshold of ambroxol solution was found to increase when the temperature of the water with which the tablets were taken, was raised from 20 to 37°C. The equation was calculated to predict the bitterness intensity of ambroxol, a function based on temperature and the ambroxol concentration using data from a standard ambroxol solution at 4, 20 and 37°C. The bitterness intensities obtained for the 10 ambroxol formulations with water at 20 and 37°C, coincided with the bitterness values predicted by the equation.

Practical resolution of (2RS, 3RS)-2-hydroxy-3-(4-methoxyphenyl)-3-(2-nitrophenylthio)propionic acid (2) was examined by the use of several basic amino acids. L-Lysine was found to be the most effective resolving agent to obtain (+)-(2S, 3S)-2,a key intermediate for the synthesis of diltiazem (1). This new method should be applicable to the industrial production of 1 in view of the simplicity of the procedure, the ready availability of L-lysine, and the high yield of the desired isomer. The absolute stereochemistry of (+)-2 was determined to be 2S, 3S by X-ray crystallographic analysis.

The direct resolution of (3aRS, 6SR, 6aSR)-1,3-dibenzyl-6-hydroxy-3,3a, 6,6a-tetrahydro-1H-furo[3,4-d]imidazole-2,4-dione [(±)-9], a key intermediate for biotin, with optically active amines was examined. Reaction of (±)-9 with cinchonidine readili gave the cinchonidine salt of the (4S, 5R)-aldehyde-carboxylic acid (12), acidification of which gave (3aS.6R, 6aR)-9,convertible to biothin. N-alkyl-D-glucamines (14) were also found to be effective resolving agents for (±)-9 applicable for industrial use. Reutilizatin of the unwanted epimer [(3aR, 6S, 6aS)-9] was effected by facile oxidation to the meso-diacid (3) with sodium chlorite.

A practical preparation of D-aspartic acid β-methyl ester [D-Asp(OMe)], a raw material for the antibiotic aspoxicillin, has been developed by the use of a second-order asymmetric transformation. The diastereomeric resolution of DL-Asp(OMe) with (-)-1-phenylethanesulfonic acid (PES) resulted in salt formation of less soluble D-・(-) and more soluble L-・(-) in acetonitrile. The soluble L-・(-) was easily epimerized into DL-・(-) by heating it in acetonitrile in the presence of catalysts. Attempted fractional crystallization of DL-・(-) or L-・(-) under such epimerizing conditions led to the desired D-・(-) in 90% yield via equilibrium asymmetric transformation in a solid-liquid heterogeneous system. Details of optimum techniques for the asymmetric transformation are presented.From these results, unique preparation processes of both D-Asp(OMe) and D-p-hydroxyphenylglycine, important intermediate materials for aspoxicillin, have been achieved by asymmetric transformation using chiral PES as the resolving agent.

Visceral obesity induces the onset of metabolic disorders such as insulin resistance and diabetes mellitus. Adipose tissue is considered as a potential pharmacological target for treating metabolic disorders. The fruit of Terminalia bellirica is extensively used in Ayurvedic medicine to treat patients with diseases such as diabetes mellitus. We previously investigated the effects of a hot water extract of T. bellirica fruit (TB) on obesity and insulin resistance in spontaneously obese type 2 diabetic mice. To determine the active ingredients of TB and their molecular mechanisms, we focused on adipocyte differentiation using mouse 3T3-L1 cells, which are widely used to study adipocyte physiology. We show here that TB enhanced the differentiation of 3T3-L1 cells to mature adipocytes and that one of the active main components was identified as gallic acid. Gallic acid (10–30 µM) enhanced the expression and secretion of adiponectin via adipocyte differentiation and also that of fatty acid binding protein-4, which is the target of peroxisome proliferator-activated receptor gamma (PPARγ), although it does not alter the expression of the upstream genes PPARγ and CCAAT enhancer binding protein alpha. In the PPARγ ligand assay, the binding of gallic acid to PPARγ was undetectable. These findings indicate that gallic acid mediates the therapeutic effects of TB on metabolic disorders by regulating adipocyte differentiation. Therefore, TB shows promise as a candidate for preventing and treating patients with metabolic syndrome.

Ethyl 5-hydroxybenzo [α] phenazine-6-carboxylates (IIa, b) were prepared by the condensation of ethyl 1,4-dihydro-1,4-dioxo-3-methoxy-2-naphthoate (I) with o-phenylene-diamines. Acylations and alkylations of IIa, b gave the corresponding o-acyl and alkyl compounds (IIIa-k). The reaction of IIa, b with ethanolamine gave β-hydroxyethyl-carboxamides (Va, b). Compound Va was converted into β-chlorinated compound (VIa), whose chlorine was substituted by dialkylamines to give ethylenediamine-type amides (VIIa, b, c). Compounds VIId and VIIe were obtained by the reaction of IIb with dialkylalkylenediamines. Oxidation of IIa, b afforded N-oxides (IXa, b). The antimicrobial activities of all synthetic compounds were tested by paper discagar diffusion assay. Compounds IIId, e, g, VIIa and IXa showed inhibitory activities to T. interdigitale and IXa to C. albicans.
