  • We studied the effect of methanol extract of Pachydictyon coriaceum (PC) on atopic allergic reaction. PC dose-dependently inhibited interleukin (IL)-8 and tumor necrosis factor (TNF)-$\alpha$ secretion from the PMA- pius A23187- stimulated HMC-1. PC also dose-dependently inhibited the histamine and $\beta$-hexosaminidase release from mast cells. PC had no cytotoxic effect. (omitted)

  • We studied the effect of methanol extract of Sargassum hemiphylum(SH) on atopic allergic reaction. SH dose-dependently inhibited interleukin (IL)-8 and tumor necrosis factor (TNF)-$\alpha$ secretion from the PMA- plus A23187- stimulated HMC-1. SH also dose-dependently inhibited the histamine and $\beta$-hexosaminidase release from mast cells. (omitted)

  • A strategy for synthesis of the furan-fused tetracyclic core of xestoquinone and halenaquinone was explored through a model study. Methyl 8-oxo-4-methyl-4-phenyl-2,7-nonadiynoate was prepared from hydratroponitrile and 3-butyn-1-ol as starting materials. The intramolecular cycloaddition of this intermediate as a key step will be involved.

  • The purposes of this study were to evaluate bioequivalence (BE) using In-transformed pharmacokinetic parameters obtained from two risperidone products and to develop the analytical methods for the quantitative determination of risperidone in human serum. In addition, the in vitro dissolution profiles of the two risperidone products in various dissolution media: pH 1.2, 4.0, 6.8 and water (KP VII Apparatus II method) were assesed. (omitted)

  • Our long-term research goals involve the SARs study and the synthetic procedure development of wogonin and its analogs. We investigated efficient synthetic pathways of wogonin and its bioisosteres in a large quantity to decipher the structural requirements for anti-inflammatory activities. We plan to serially delete or modify the 5,7-dihydroxyl groups of wogonin to observe the effects of the hydroxyl groups on anti-inflammatory activity. Also we modofied the 8- methoxy group on a ring since it is known to be necessary for biological activity. (omitted)

  • Juglone and naphthazarine derivatives were newly systhesized for the evaluation of antifungal activities. These derivatives were prepared by methylation of juglone and 2, 3-dichloro-5, 8-dihydroxy-l, 4-naphthoquinone, and by regioselective nucleophilic subsitution with arylthiols. All compounds were tested in vitro for their growth inhibitory activities against pathogenic fungi by the standard method. The MIC values were determined by comparison to flucytosine as a standard agent. (omitted)

  • In galactose metabolic pathway : there are three inborn metabolic disorders galactokinase deficiency (galactosemia type II), galactose-1-phosphate uridyl transferase(GALT) daficiency (galactosemia type I ), uridine diphosphate galactose-4-epimerase deficiency (galactosemia typeIII). Among these disorders GALT deficiency is the most severe and common. Infants with GALT deficiency fail to metabolize galactose-1-phosphate. As a consequence, galactose-1-phosphate and galactose are accumulated in blood in which GALS enzyme plays the role of a pathognomonic marker. (omitted)

  • On the purpose of develcpement of antioxidative compound from natural sources, medicinal plants known to have antioxidant actuvity have been examined concening DPPH radical scavenging activity and SOD-liked activities. Among 8 plants exhibiting the activity, Houttuynia cordata THUNB was selected as resources to search for active compounds due to rareness of study. The antioxidative compounds from Houttuynia cordata THUNB,quercitrin was assayed using a DPPH free radical. The DPPH radical scavenging activity of quercitrin was similar to that of BHA and Ascorbic acid

  • Purpose. To develop a hard gelatine capsule containing meloxicam (Yuhan Meloxam capsule$\^$TM/), in vitro dissolution characteristics and bioavailability in beagle dog were compared with commercial product (Mobic capsule$\^$TM/). Methods. Meloxicam capsule$\^$TM/ was prepared by powder filling method using meloxicam, lactose, magnesium stearate, and others. The release of Meloxicam capsule$\^$TM/ and Mobic capsule$\^$Tm/ were monitored by USP dissolution method under various dissolution donditions - dissolution medium (pH 1.2, 4.0, 6.8 and water).
