  • 본 연구에서는 마른진흙버섯 자실체를 메탄올과 열수를 이용해 추출한 물질의 anti-xanthine oxidase, anti-cholinesterase 및 염증 저해 효과에 대한 연구를 수행하였다. 마른진흙버섯 자실체의 메탄올 추출물과 열수 추출물의 xanthine oxidase에 대한 저해효과는 양성대조군으로 사용한 allopurinol과 대등하게 높은 효과를 나타냈다. Acetylcholinesterase에 대한 메탄올 추출물의 1.0~2.0 mg/mL 농도에서의 저해활성은 양성대조군인 galanthamine과 유사하게 높았지만 butyrylcholinesterase에 대한 메탄올과 열수 추출물의 저해활성은 양성대조군에 비해 실험에 사용한 모든 농도범위에서 유의하게 낮았다. PC-12 세포에 glutamate의 처리에 의해 유도된 독성은 40 mg/mL와 100 mg/mL 농도의 메탄올 추출물과 100 mg/mL 농도의 열수추출물의 처리에 의해 크게 완화되어 PC-12 세포의 생존율이 유의하게 증가하는 것이 관찰되었다. 마른진흙버섯의 메탄올과 열수 추출물의 염증 저해 실험에서 RAW 264.7 대식세포에 메탄올 추출물을 2.0 mg/mL 농도로 처리하고 염증을 매개하는 LPS를 추가로 투여한 후 RAW 264.7 세포에 생성되는 NO를 측정한 결과, 양성대조군에 비해 3.37배 높은 저해효과를 나타냈고, 처리한 자실체 메탄올 추출물의 농도가 증가함에 따라 생성된 NO의 양이 현저하게 감소하는 경향을 나타내었다. 또한 기염제인 carrageenan에 의해 흰쥐 뒷발에 유도된 부종 저해 실험에서는 투여한 버섯 추출물의 농도가 증가함에 따라 흰쥐의 뒷발에 유도된 부종의 용적이 농도 의존적으로 감소하는 경향을 나타냈다. 따라서 마른진흙버섯 자실체에 함유된 물질은 acetylcholinesterase과 butyrylcholinesterase 등의 cholinesterase에 대한 저해작용과 glutamate에 의해 유도된 PC-12세포의 독성을 완화하고 또한 염증을 저해하는 효과를 나타내 기억력이 감퇴되는 초기 알츠하이머병과 염증을 완화하는 천연소염제로의 이용이 가능할 것으로 사료된다.

  • This study was initiated to investigate antioxidant, anti-acetylcholinesterase, and xanthine oxidase inhibitory activities and properties of fruiting bodies, mycelia, and fermentation culture filtrates from Phellinus igniarius. The contents of total phenols and flavonoid of fruit bodies, mycelia, and culture filtrate were 15.35-1.36 mg/g, 10.35-7.85 mg/g, and 8.25-5.36 mg/g. The 1,1-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging abilities of the extracts from the fruiting bodies, mycelia, and culture filtrates were 90.25-95.60%, 78.82-85.24%, and 76.32-82.50% at $50-400{\mu}g/mL$, respectively. The chelating ability of fruiting body extract on ferrous ions was higher than those of mycelia and culture filtrates tested. The anti-acetylcholinesterase inhibitory activity of the fruiting body extract at 400 ${mu}g/mg$ exhibited 91.10% on AChE, which is lower than that of positive control, galanthamine (94.82%). The xanthine oxidase inhibitory activities of the fruiting bodies, mycelia, and culture extract were 85.47%, 78.13%, and 72.49% at 400 ${\mu}g/mL$, respectively. Overall, the fruiting body extract has better anti-acetylcholinesterase, antioxidant and xanthine oxidase inhibitory activities than those from mycelia and culture filtrate.

  • In this study, the antioxidant, anti-xanthine oxidase, anti-melanogenic and anti-wrinkle effects of methanol (ME) and hot water (HE) extracts from the fruiting bodies of Phellinus vaninii were investigated. The 1,1-diphenyl-2-picryl-hydrazyl free radical scavenging activity of 2.0 mg/mL HE (95.38%) was comparable to that of butylated hydroxytoluene (96.97%), the reference standard. The hydroxyl radical scavenging activities of ME (98.19%) and HE (97.55%) were higher than that of butylated hydroxytoluene (92.66%) at 2.0 mg/mL. Neither ME nor HE was cytotoxic to murine melanoma B16-F10 cells at 25-750 ㎍/mL. Although the xanthine oxidase (XO) inhibitory effects of ME and HE were significantly lower than that of allopurinol, the values were higher than 84 percent. The in vitro tyrosinase inhibitory activities of ME and HE were comparable to kojic acid at 2.0 mg/mL. The cellular tyrosinase and melanin synthetic activities of ME and HE on B16-F10 melanoma cells at 500 ㎍/mL were higher than arbutin, indicating that the inhibitory effects of arbutin on the tyrosinase and melanin synthesis were higher than those of ME and HE. The collagenase inhibitory activity of HE was comparable to EGCG at 2.0 mg/mL, however, the elastase inhibitory activity of ME and HE was lower than EGCG at the concentration tested. The study results demonstrated that the fruiting bodies of Ph. vaninii possessed good antioxidant, anti-xanthine oxidase, cell-free anti-tyrosinase, cellular anti-tyrosinase, anti-collagenase, and moderate anti-elastase activities, which might be used for the development of novel anti-gout, skin-whitening, and skin anti-wrinkle agents.

  • We selected Pleurotus ostreatus from among several edible mushrooms because it has high anti-gout xanthine oxidase (XOD) inhibitory activity. The maximal amount of XOD inhibitor was extracted when the Pleurotus ostreatus fruiting body was treated with distilled water at $40^{\circ}C$ for 48 hr. The XOD inhibitor thus obtained was purified by Sephadex G-50 gel permeation chromatography, ultrafiltration, $C_{18}$ solid phase extraction chromatography and reverse-phase high-performance liquid chromatography with 3% of solid yield, and its XOD inhibitory activity was 0.9 mg/mL of $IC_{50}$. The purified XOD inhibitor was a tripeptide with the amino acid sequence phenylalanine-cysteine-histidine and a molecular weight of 441.3 Da. The XOD inhibitor-containing ultrafiltrates from Pleurotus ostreatus demonstrated dose-dependent anti-gout effects in a Sprague-Dawley rat model of potassium oxonate-induced gout, as shown by decreased serum urated levels at doses of 500 and 1,000 mg/kg, although the effect was not as great as that achieved with the commercial anti-gout agent, allopurinol when administered at a dose of 50 mg/kg.

  • Chalcone, (2E)-1,3-Diphenylprop-2-en-1-one, and its synthetic derivatives are known to possess anti-oxidative and anti-inflammatory properties. In the present study, we prepared a novel synthetic chalcone compound, (E)-1-(4-hydroxyphenyl)-3-(2-(trifluoromethoxy)phenyl)prop-2-en-1-one name (YJI-7), and investigated its inhibitory effects on endotoxin-stimulated production of reactive oxygen species (ROS) and expression of inflammatory mediators in macrophages. We demonstrated that treatment of RAW 264.7 macrophages with YJI-7 significantly suppressed lipopolysaccharide (LPS)-stimulated ROS production. We also found that YJI-7 substantially decreased NADPH oxidase activity stimulated by LPS, indicating that YJI-7 regulates ROS production via modulation of NADPH oxidase in macrophages. Furthermore, YJI-7 strongly inhibited the expression of a number of inflammatory mediators in a gene-selective manner, suggesting that YJI-7 possesses potent anti-inflammatory properties, as well as anti-oxidative activity. In continuing experiments to investigate the mechanisms that could underlie such biological effects, we revealed that YJI-7 suppressed phosphorylation of p38MAPK and JNK stimulated by LPS, whereas no significant effect on ERK was observed. Furthermore, LPS-stimulated production of ROS, activation of NADPH oxidase and expression of inflammatory mediators were markedly suppressed by treatment with selective inhibitor of p38MAPK (SB203580) and JNK (SP600125). Taken together, these results demonstrated that YJI-7, a novel synthetic chalcone derivative, suppressed LPS-stimulated ROS production via modulation of NADPH oxidase and diminished expression of inflammatory mediators, at least in part, via down-regulation of p38MAPK and JNK signaling in macrophages.
