  • Background: Inflammation is widespread in the clinical pathology and closely associated to the progress of many diseases. Triterpenoid saponins as a key group of active ingredients in Panax notoginseng (Burk.) F.H. Chen were demonstrated to show antiinflammatory effects. However, the chemical structures of saponins in the leaves and stems of Panax notoginseng (PNLS) are still not fully clear. Herein, the isolation, purification and further evaluation of the antiinflammatory activity of dammarane-type triterpenoid saponins from PNLS were conducted. Methods: Silica gel and reversed-phase C8 column chromatography were used. Furthermore, preparative HPLC was used as a final purification technique to obtain minor saponins with high purities. MS, NMR experiments, and chemical methods were used in the structural identifications. The antiinflammatory activities of the isolated saponins were assessed by measuring the nitric oxide production in RAW 264.7 cells stimulated by lipopolysaccharides. Real-time reverse transcription polymerase chain reaction was used to measure the gene expressions of inflammation-related gene. Results: Eight new minor dammarane-type triterpene oligoglycosides, namely notoginsenosides LK1-LK8 (1-8) were obtained from PNLS, along with seven known ones. Among the isolated saponins, gypenoside IX significantly suppressed the nitric oxide production and inflammatory cytokines including tumor necrosis $factor-{\alpha}$, interleukin 10, interferon-inducible protein 10 and $interleukin-1{\beta}$. Conclusion: The eight saponins may enrich and expand the chemical library of saponins in Panax genus. Moreover, it is reported for the first time that gypenoside IX showed moderate antiinflammatory activity.

  • In this inverstigation, the various flavonoid aglycones were evaluated for their inhibitory activities against croton-oil or arachidonic acid induced mouse ear edema by oral or topical administration. The compounds tested were thirteen derivatives of flavan-3-ol(catechin and epicatechin), flavanone (flavanone and naringenin), flavone (flavone, chrysin and apigenin), flavonol(favonol, galangin, quercetin and morin) and isoflavone (biochanin A and 2-carbethoxy-5,7-dihydroxy-4'-methoxyisoflavone), along with hydrocortisone, indomethacin, 4-bormophenacyl bromide, nordihydroguaiaretic acid and phenidone as positive controls. A(isoflavone) were found to show broad inhibitoty activities (14-52%) against croton-oil or arachidonic acid induced ear edema by oral or topical application at the dose of 2 mg/mouse, although they showed less activity than hydrocortisone (26-88%) or indomethacin (36-80%). Flavonoid agtlycones tested showed higher activity when aplied topically than by the oral administration. It was also found that they inhibited arachidonic acid induced edema more profoundly than croton-oil induced edema by topical application. In arachidonic acid induced edema when applied topically, flavone derivatives such as flavone, chrysin and apigenin were revealed to be the good inhibitory agents in addition to flavonols and isoflavones. When quercetin and biochanin. A were selected for evaluating in carrageenan induced rat pleurisy and biochanin both flavonoids showed antiinflammatory activity at the dose of 70 mg/kg by the oral adminis-tration. All of these results revealed that flavonoid aglycones, especially 5,7-dihydroxy-flavonols having hydroxyl group(s) in B-ring and biochanin A (isoflavone) possessed in vivo antiinflammatory activity.

  • The purpose of this study was evaluated physiological activity of processed sulfur with Cordyceps militaris mycelium that antioxidative and antiinflammatory effects. Proliferation of processed sulfur (PS) with Cordyceps militaris mycelium was increased in dose-dependent manner. In organic sulfur contents of Cordyceps militalis mycelium fortified processed sulfur, CM+PSH (CM+3000 ppm of PS) was significantly higher than other groups. However, CM+PSL (CM+1500 ppm of PS) was almost changed organic sulfur. Content of total polyphenol compounds was similarity to CM, CM+PSL and CM+PSH. The EDA (electron donating ability) and SOD-like activity was increased in dose-dependent manner and the activity of CM were significantly higher than CM+PSL and CM+PSH. We examined cytotoxicity, nitric oxide production of Raw 264.7 cell and inhibition of HT 1080 cell by MTT assay. CM, CM+PSL and CM+PSH do not have any toxic effects in macrophages (Raw 264.7). And CM+PSL and CM+PSH inhibited the production of nitrite in Raw 264.7 cells activated with LPS. The antitumor effects of processed sulfur with Cordyceps militaris mycelium on HT 1080 cell was indicated a significantly inhibition activity. These results suggested that processed sulfur with Cordyceps militaris mycelium have activities of antioxidant, antiinflammatory effects.

  • The antiinflammatory activity of Phytolacca saponin and phytolaccagenin isolated from the roots of Phytolacca americana has been investigated. When Phytolacca saponin and phytolaccagenin were given parenterally exhibited potent inhibitory effects on acute edema in rats and in mice. while oral administrtion required 6 times more dosage in comparison with that of intrapertioneal injection. The anti-exudative and anti-granulomatous activities of the saponin showed as much as the dose of 8 times higher than that of hydrocortisone. The saponin appeared to be of no effects on adrenal, however, showed a severe thymolysis at high dose.

  • Eight derivatives of arylpropionic acid, arylcarbonylpropicnic acid, and arylhydroxybutyric acid were synthesized and their structures were elucidated on the basis of elemental analysis and spectral data. Also their antiinflammatory activities were evaluated by the method of the inhibitory effect on the carrageenin-induced rat paw edema and compared with phenylbutazone. Compound (I) exhibited 59% edema inhibition vs control when 100 mg/kg, was orally administered, whereas phenylbutazone showed 57.8% for 50mg/kg.

  • Quercetin is one of flavonoids widely distributed in the plants and well known to have antioxidants, antiinflammatory, antimicrobial properties. In this study, alginate sponge containing quercetin-encapsulated nanocapsules was prepared by miniemulsion polymerization, dyring/crosslinking method and their bioactive characteristics were investigated. Alginate sponge containing quercetin-encapsulated nanocapsules were evaluated using a field emission scanning electron microscope(FE-SEM), a high performance liquid chromatography, cell viability, DPPH radical scavenging activity and antibacterial activity. The study indicates that alginate sponge containing quercetin-encapsulated nanocapsules had significant antioxidant, antiinflammatory and antibacterial activities. This study suggested that alginate sponge containing quercetin-encapsulated nanocapsules can be a potential candidate for medical materials.

  • Aqueous extract of Morus alba L. blocked the toxic effect of paraquat on E. coli growth. The active components in the extract may be capable of crossing the cell membranes and protect against superoxide toxicity in E. coli, The extract inhibited $FeSO_4/H_2O_2$ induced lipid peroxidation in rat liver homogenate and protected against t-butyl hydroperoxide caused Ac2F cell damage. Moreover, the extract showed inhibitory effect on phospholipase $A_2$ activity in a dose dependent manner. Antiinflammatory effect of the extract was further investigated using the carrageenin-induced oedema model. A single adminstration of the extract (3g/kg body, p.o.) was more effective than indomethacin. These results suggest that the isolation and identification of the active components would have significant therapeutic application to inflammation associated with oxygen radicals.

  • The present investigation deals with the synthesis of some new salicylamidoacetyl sulfonamides 3a,b, salicylamido ethylacetate 4, salicylamido acetic acid hydrazide 5, which is considered as the key intermediate for the synthesis of several series of new compounds such as salicylamido pyrazol 6 and pyrazolone 1. N-imido-derivatives 9, 10, 11, thiadiazole 13, oxadiazole 14, 15, Schiffs bases 16a-f. Cyclocondensation of Schiffs bases with thioglycolic acid gave thiazolidinone 18a-c while with acetylchloride afforded azitidinones 19a-c and with acetic anhydride gave 1,4-benzoxazepine-3,5-dione. Some of the compounds were tested for their analgesic and antiinflammatory activities as well as ulcerogenic effects. Some derivatives were more effective than salicylamide and ulcerogenic activity was variably lowered .
