The bioassay-guided fractionation of MeOH extract from Naematoloma fasciculare afforded a petroleum ether fraction (NFPF) and four known compounds, which showed good antitumor activities to inhibit MCF-7 cell line proliferation in vitro and tumor growth in $H_{22}$ implanted mice in vivo. In addition, a number of unsaturated aliphatic acids were identified in NFPF by GC analysis. These results showed that NFPF inhibits tumor growth through the activity of unsaturated aliphatic acids together with two active compounds, ergosterol peroxide (1: 62.17 mg/g in NFPF) and ergosterol (2: 3.13 mg/g in NFPF), and indicate the potential utility of NFPF as an antitumor drug.

A very high content (at least 0.23%) of ergosterol peroxide was isolated from Naematoloma fasciculare Karst. Not only ergosterol peroxide but also ergosterol showed very strong anticomplementary activity on the classical pathway, the $IC_{50}$ values being $5.0 {\mu}M$ and $1.0 {\mu}M$, respectively. The $ ^{1}H $and $^{13}C$ NMR data of ergosterol peroxide were revised and completely assigned by DEPT, $^{1}H-^{1}H$ COSY, HMQC and HMBC correlations.

한국에 야생하는 독버섯의 하나인 노란다발버섯을 물로 가열 추출한 후 추출액에 3배의 에탄올을 첨가하여 고분자 물질을 침전시켰으며 이를 다시 투석하여 정제 하였다. 이것을 냉동 건조하여 분말을 얻었으며 60mg/kg 용량을 백서의 복강내에 주사 하였던 바, 6일 후 부터 사망하기 시작하여 7일째에는 7마리중 4마리가 절명하였다. 이 유독 성분을 "네마톡신"이라 명명하고자 한다.

In our ongoing search for structurally interesting and biologically active metabolites from Korean wild mushrooms, bioassay-guided fractionation and a chemical investigation of the MeOH extracts of the fruiting bodies of the mushroom Naematoloma fasciculare resulted in the isolation of three ergosterol derivatives, (22E,24R)-ergosta-7,22-diene-$3{\beta}$,$5{\alpha}$,$6{\beta}$,$9{\alpha}$-tetrol (1), (22E,24R)-$5{\alpha}$,$8{\alpha}$-epidioxyergosta-6,22-diene-$3{\beta}$-ol 3-O-${\beta}$-$\small{D}$-glucopyranoside (2), and (22E,24R)-$5{\alpha}$,$8{\alpha}$-epidioxyergosta-6,9,22-triene-$3{\beta}$-ol 3-O-${\beta}$-$\small{D}$-glucopyranoside (3). The structures of 1 - 3 were determined by comparison of their spectroscopic and physical data with reported values. The isolated steroid derivatives 1 and 3 were reported for the first time from this mushroom. Compounds 1 - 3 were tested for their cytotoxic activities against four human cancer cell lines (A549, SK-OV-3, SK-MEL-2, and HCT-15).

The carpophores of a mushroom, Naematoloma fasciculare (Fr.) Karst, were extracted with 0.2 N NaOH and the extract was dialyzed through visking tube. It was found to contain an antitumor activity against sarcoma 180 implanted in mice. The components of this aqueous extract were found to be a polysaccharide and a protein by color reactions including Anthrone and Lowery-Folin tests. The hydrolysis of the polysaccharide with 3% HCL-Me-OH and trimethylsily lation of the hydrolysate yielded five monosaccharides, i. e. glucose, frutose, mannose, galactose and xylose, which were detected and analyzed by GLC. After hydrolysis of the protein with 6N HCl, 15 amino acids, including aspartic acid and glutamic acid, were detected and analyzed by an auto amino acid analyzer.

오대산에 자생하는 야생버섯 60종의 메탄올추출물을 이용하여 혈관계 질환과 당뇨병의 치료에 효과 있는 버섯을 확인하기위해, 혈전용해 활성과 ${\alpha}-glucosidase$ 저해 활성을 확인한 결과 11종의 버섯이 혈전용해 활성을 나타냈고, 6종의 버섯이 50% 이상의 ${\alpha}-glucosidase$ 저해 활성을 나타냈다. 뽕나무버섯류가 4.2 plasmin units의 가장 큰 혈전용해 활성을 나타냈으며, 독우산광대버섯, 미치광이 버섯류, 민자주방망이버섯이 2.3 plasmin units, 애괄대버섯은 2.1 plasmin units, 흰보라끈적버섯은 2.0 plasmin units 의 높은 혈전용해 활성을 나타냈다. ${\alpha}-Glucosidase$ 저해 활성 측정결과 노란다발버섯이 98.5%의 가장 큰 저해 활성을 나타냈고 비단그물버섯과 점마개버섯도 60% 이상의 높은 저해 활성을 나타냈다. 본 연구는 뽕나무벗섯류와 노란다발버섯은 혈관계질환 치료용 의약이나 기능성 식품으로 개발될 수 있음을 보여준다.

천연물질로부터 항돌연변이원성 물질 및 항암 물질 탐색을 위한 연구의 일환으로 11종의 국내산 야생 버섯류로 부터 메탄올 추출물을 제조한 후 Ames test를 이용하여 돌연변이 억제효과를 검토하였다. 실험에 사용한 농도에서 털이버섯(Lactarius piperatus), 노란다발독버섯(Naematolona fasciculare) 및 금빛시루뻔버섯(Innotus xeran- ticus)의 메탄올 추출물은 Salminella typhimurium Ta98 및 TA100 균주에서 추출물의 농도에 관계없이 간접변이원인 B(a)P에 대하여 40~80% 정도의 항돌연변이 효과를 나타내었으며, 직접변이원인 MNNG에 대해서는 60~80% 정도의 비교적 높은 돌연변이 억제효과를 나타내었다.

This study was conducted to evaluate the degradation of aromatic dyes and the production of ligninolytic enzymes by 10 white rot fungi. The results of this study revealed that Pycnoporus cinnabarinus, Pleurotus pulmonarius, Ganoderma lucidum, Trametes suaveolens, Stereum ostrea and Fomes fomentarius have the ability to efficiently degrade congo red on solid media. However, malachite green inhibited the mycelial growth of these organisms. Therefore, they did not effectively decolorize malachite green on solid media. However, P. cinnabarinus and P. pulmonarius were able to effectively decolorize malachite green on solid media. T. suaveolens and F. rosea decolorized methylene blue more effectively than any of the other fungi evaluated in this study. In liquid culture, G. lucidum, P. cinnabarinus, Naematoloma fasciculare and Pycnoporus coccineus were found to have a greater ability to decolorize congo red. In addition, P. cinnabarinus, G lucidum and T. suaveolens decolorized methylene blue in liquid media more effectively than any of the other organisms evaluated in this study. Only F. fomentarius was able to decolorize malachite green in liquid media, and its ability to do so was limited. To investigate the production of ligninolytic enzymes in media containing aromatic compounds, fungi were cultured in naphthalene supple mented liquid media. P. coccineus, Coriolus versicolor and P. cinnabarinus were found to produce a large amount of laccase when grown in medium that contained napthalene.
