  • 3-Aryloxy methyl-4-(N-pyrazin-2'yl carboxamido)-5-mercapto-1,2,4-triazoles (3a1-a14) were prepared starting from potassium dithio carbazinates (2a1-a14). These triazoles were then employed in the synthesis of 3-aryloxy methyl-4-(N-pyrazin-2'yl carboxamido)-5-hydrazino-1,2,4-triazoles (4a1-a14). All the newly synthesized compounds were characterized by analytical, IR, NMR spectral studies. The compounds were screened for their antibacterial, antifungal, anti-inflammatory and analgesic properties. Most of the compounds have shown significant antifungal activity while few have shown excellent anti-inflammatory and analgesic activity. An attempt is made to study the structure activity relationship (SAR).

  • Betulae Cortex of Betula platyphylla Suk. var. japonica Hara (Betulaceae) has long been used for treatment of various inflammation, fever and cough in Eastern Asia. In order to investigate antibacterial activity of the Betulae Cortex against Streptococcus mutans or Porphyromonas gingivalis, MIC (minimal inhibitory concentration) and pH were checked, and for anti-inflammation activity, the experiments about trypsin-induced paw edema, vascular permeability and myeloperoxidase activity in rat's hind-paw tissue, were carried out with various extracts of Betulae Cortex (BCXs) respectively. The BCXs showed significant antibacterial activity, and at the dose of over 50 mg/kg, BCX showed significant inhibition on the paw edema, vascular permeability and myeloperoxidase activity. These results indicate that BCXs have antibacterial activity against oral cariogenic bacteria and anti-inflammatory effect.

  • Besides (-) pimara-8(14), 15-dien-19-oic acid [I] which had already been isolated as an active anti-inflammtory principle of Aralia continentalis, (-) kaur-16-en-19-oic acid [II] was separated as another active component of the plant, by tracing albumin stabilizing activity. $IC_{50}$ of [II] for the protein stabilizing activity was 0.026mg/3ml, when those of [I] and phenylbutazone were 0.032 and 0.32 mg/3ml, respectively. Being investigated employing carrageenin-induced edema test in rat hind paw, the anti-inflammatory activity of [II] administered s. c. was slightly lower than that of phenylbutazone, whereas the activity of [II] administered p. p. was three times greater than that of phenylbutazone. These results of [II] were contrary to those of [I] in the aspect of administration routes.

  • The anti-inflammatory activity of SEO-KYONG-TANG extract(SKTWE) was examined by using carrageenin- and acetic acid-induced edema, croton oil-induced granuloma pouch, and adjuvant arthritis in rats. In addition, the acute toxicity, analgesic and antipyretic effects of SKTWE were investigated by using general experimental methods in mice. SKTWE did not show acute toxicity at 2400 mg/kg(p.o.) nor 1200 mg/kg(i.p.). After oral administration of the SKTWE to rats, significant anti-inflammatory activity was observed on 1% carrageenin- and 5% acetic acid-induced edema. Also, it significantly inhibited granuloma and exudation in these. In the adjuvant arthritis experiment, the SKTWE decreased the hind paw edema after 3 days of oral administration. In addition, it inhibited the writhing syndromes induced by 0.7% acetic acid in mice. The antipyretic activity of SKTWE was also observed through the typhoid vaccine experiment. These results suggest that SKTWE has analgesic, anti-inflammatory and antipyretic action.

  • Oxidative stress has been reported to be one of causes of neuritis. This study examined antioxidative activities of methanol extracts of six amphibian species known to be medicinal animals (Rana catesbeiana, R. coreana, R. rugosa, R. dybowskii, R. nigromaculata, and Hyla japonica) and investigated their effects of inhibiting nitric oxide (NO) production and cytotoxicity on the murine macrophage RAW264.7 cells. As inflammation is closely associated with reactive oxygen species, assays on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, xanthine oxidase inhibitory activity, superoxide anion radical scavenging activity and NO scavenging activity of the extracts of the six species were performed to investigate their antioxidative activity. The results obtained were as follows; All extracts showed antioxidative activity, and the activity of R. dybowskii was the highest in comparison among those. Anti-inflammatory effects of the extracts were also examined, the five extracts except that of R. rugosa did not show cytotoxicity for RAW264.7 cells at the maximal concentration ($1,000{\mu}g\;mL^{-1}$). Selectivity index, meaning NO scavenging activity compared to cytotoxicity, showed the highest level in the extract of R. dybowskii. These results will be very useful basic data for future studies on prevention and treatment of human diseases to understand the biological roles of amphibian extracts throughout the antioxidative or anti-inflammatory pathways.
