ジャーナル フリーThe ginsenoside-β-glucosidase that hydrolyzes the β-(1→2)-glucoside of the ginsenoside Rg3 sugar moiety to ginsenoside Rh2 was isolated from the ginseng root, and the enzyme was purified and characterized. The enzyme was purified to one spot in SDS polyacrylamide gel electrophoresis, and its molecular weight was about 59 kDa. The optimum temperature of the ginsenoside-β-glucosidase was 60 °C, and the optimum pH was 5.0. Ca2+ ion had positive effect on ginsenoside-β-glucosidase, while Cu2+ had negative effect on it. The ginsenoside-β-glucosidase may be a special β-glucosidase that is different from the original exocellulase such as β-glucosidase (EC 3.2.1.21).抄録全体を表示PDF形式でダウンロード (67K) -

ジャーナル フリーA novel series of indolizinebutyric acids with various benzoyl substituents was synthesized to develop nonsteroidal inhibitors of steroid 5α-reductase, and the structure-activity relationships in this series were studied. We previously reported the structure-activity relationships in a series of indolebutyric acids as well as the discovery of the novel nonsteroidal 5α-reductase inhibitor, FK143. We have now made other modifications to this compound to improve in vivo inhibitory activity. By altering the heterocyclic nucleus and changing the benzoyl substituent we have succeeded in identifying the strongly active compound, FK687, (S)-4-[1-[4-[[1-(4-isobutylphenyl)butyl]oxy]benzoyl]indolizin-3-yl]butyric acid, which displays strong in vitro inhibitory activity against the human enzyme and in vivo inhibitory activity against the castrated young rat model. This compound should be a useful agent for the treatment of benign prostatic hyperplasia.抄録全体を表示PDF形式でダウンロード (166K) -

ジャーナル フリーA new β-cyclodextrin (β-CD) derivative, mono[6-deoxy-6-(2-butenedinitrile-2, 3-dimercapto sodium salt)]-β-CD (6-mnt-β-CD), and its inclusion compound with a ferrocenium drug, have been prepared and characterized by IR, UV, 13C-NMR spectroscopy, and mass spectrometry, elemental analysis, thermogravimetry, and cyclic voltammetry (CV). The interplay between the side-arm anion of β-CD and the ferrocenium (guest) in the inclusion compound 6-mnt-β-CD-/Fc+ has been investigated by 13C-NMR, UV, IR, and thermogravimetric methods. Charge transfer from the anion to the cation in 6-mnt-β-CD-/Fc+ was then experimentally identified. The interaction between the guest and the host with side-arm in 6-mnt-β-CD-/Fc+ resulted in smaller positive potential shifts compared to that in the inclusion compound [β-CD/Fc+]BF4-.抄録全体を表示PDF形式でダウンロード (61K) -

ジャーナル フリーA novel series of acyl-CoA: cholesterol O-acyltransferase (ACAT) inhibitors were synthesized from a lead compound, 1-(4-hydroxy-3-methoxyphenyl)-7-phenylhept-1-en-3-one (1, Yakuchinone B) through a modification of three regions (A, B, C) in the molecule. In this study, the compounds prepared were tested for in vitro inhibitory activity on microsomal ACAT from the liver of rats and for in vivo hypocholesterolemic activity in rats given a high cholesterol diet. N-(3,5-Dimethoxy-4-n-octyloxycinnamoyl)-N'-(3,4-dimethylphenyl)piperazine (45), which belongs to the amide compounds, has finally been discovered. Compound 45 inhibited rat hepatic ACAT in a more striking manner than CI-976, an amide compound ACAT inhibitor, and it exhibited a high level of hypocholesterolemic activity in vivo. Since 45 strongly inhibited both microsomal ACAT prepared from HepG2 (a cell line derived from human hepatocarcinoma) and Caco2 (a cell line derived from human colon adenocarcinoma), there is speculation that 45 might have the ability to inhibit ACAT in both the human intestine and liver independent of the difference in the distribution of ACAT isozymes. On the other hand, 45 did not induce adrenotoxicity in subacute toxicity studies in rats. These results suggest that it has promise for development as a new therapeutic agent for hypercholesterolemia and atherosclerosis.抄録全体を表示PDF形式でダウンロード (111K) -

ジャーナル フリーThe antimalarial agent halofantrine penetrates dipalmitolylphosphatidylcholine (DPPC) monolayers resulting in an increase in surface pressure and an expansion in area occupied by the lipid components of the monolayer. This phenomenon is observed at concentrations (0.05-0.2 μM) of halofantrine that have no surface activity. Penetration increases with drug concentration and is greatest at low initial surface pressures of the monolayer. A critical surface pressure of the DPPC monolayer has been determined from constant area and constant pressure conditions. The magnitude of these values support the hypothesis that halofantrine readily penetrates the DPPC monolayers. The presence of cholesterol in the DPPC monolayer hampers penetration and a lower critical surface pressure is obtained under such conditions. Even then, a slower rate of penetration is observed only in monolayers maintained at high initial surface pressures (10, 15 mN/m), corresponding to the liquid condensed phase of the monolayer, and not at low surface pressures (2.5, 5.0 mN/m). These results help to give a better understanding of the dynamics of the halofantrine-phospholipid interaction as well as the pharmacodynamic character of the drug.抄録全体を表示PDF形式でダウンロード (65K) -

ジャーナル フリーSeparation of twelve sympathomimetic amines and related compounds by micellar electrokinetic chromatography (MEKC) with UV absorbance detection is described. These amines were well separated within 25 min using 50 mM sodium tetraborate solution containing 15 mM sodium dodecylsulfate (SDS) of pH 9.3 as a running solution and detected at 210 nm. MEKC was performed with an applied voltage of 13 kV at 25 °C using a fused-silica capillary (50 cm×75 mm i.d.) with effective length of 37.5 cm. The detection limits of these compounds were in the range from 4 to 97 fmol/injection at a signal-to-noise ratio (S/N) of 3. The reproducibility of the method expressed as relative standard deviation (RSD) for within-day (n=6) and between-day (n=5) assays was less than 4.8 and 8.8%, respectively. The proposed method could be applied to the determination of an anorectic drug, phentermine, in Chinese tea with a detection limit of 99 μg/g (105 fmol/injection, S/N=3).抄録全体を表示PDF形式でダウンロード (68K) -
