Cordycepin, a nucleoside-derivative-isolated form Cordyceps militaris, has been reported to suppress tumor cell proliferation and cause apoptosis. This study investigates the effect of cordycepin on the migration of human glioblastoma cells. Cordycepin suppressed the migration of the human glioblastoma cell lines U87MG and LN229 in transwell and wound healing assays. Cordycepin decreased protein expression of integrin α1, focal adhesion kinase (FAK), p-FAK, paxillin and p-paxillin. The lysosomal inhibitor NH4Cl blocked the ability of cordycepin to inhibit focal adhesion protein expression and glioma cell migration...

This research shows the phenolic composition and anti-inflammation properties of fruiting bodies and mycelia of 15 strains of 12 species of higher Basidiomycetes medicinal mushrooms. In this research, 15 extracts were prepared and their effects on inflammation-related mediators in RAW 264.7 cells were evaluated. In the extracts, amounts of total phenols ranged from 8.47 to 70.32 gallic acid equivalents mg/g and amounts of flavonoids ranged from 0.13 to 15.21 rutin equivalents mg/g. The production of nitric oxide, tumor necrosis factor-α, and interleukin-6 was decreased at different levels by these extracts, whereas the production of interleukin-10 was increased by 6 of the extracts...

BACKGROUND: A species of the fungal genus Cordyceps has been used as a complementary and alternative medicine of traditional Chinese medicine, and its major component cordycepin and cordycepin-enriched WIB-801CE are known to have antiplatelet effects in vitro. However, it is unknown whether they have also endogenous antiplatelet and antithrombotic effects. In this study, to resolve these doubts, we prepared cordycepin-enriched WIB-801CE, an ethanol extract from Cordyceps militaris-hypha, then evaluated its ex vivo, in vivo, and in vitro antiplatelet and antithrombotic effects...

The antibacterial agent helvolic acid, which was isolated from the active antitumor fraction of Cordyceps taii, showed potent cytotoxicity against different human cancer cells. In the present study, the in vivo antitumor effect of helvolic acid was investigated in murine sarcoma S180 tumor-bearing mice. Doses of 10 and 20 mg/kg/day helvolic acid did not exert significant antitumor activity. Interestingly, co-administration of 10 mg/kg/day helvolic acid and 20 mg/kg/day cyclophosphamide (CTX) - a well-known chemotherapy drug - showed promising antitumor activity with a growth inhibitory rate of 70...

The structural properties and the inhibition on α-d-glucosidase activity of the low molecular weight (LCMPs-II) obtained from the optimized acid hydrolysis of the Cordyceps militaris polysaccharides (CMPs) were investigated in this paper. The LCMPs-II with a molecular weight of 28 KDa mainly composed of rhamnose, xylose and glucose with the molar ratio of 1: 2.19: 6.73 was separated from LCMPs-I which was the acid hydrolysis product of CMPs by chromatography on Sephadex G-100 column. The solubility of LCMPs-II was tested to be 32...

Cordyceps bassiana is one of Cordyceps species with anti-oxidative, anti-cancer, anti-inflammatory, anti-diabetic, anti-obesity, anti-angiogenic, and anti-nociceptive activities. This mushroom has recently demonstrated to have an ability to reduce 2,4-dinitrofluorobenzene-induced atopic dermatitis symptoms in NC/Nga mice. In this study, we further examined phytochemical properties of this mushroom by column chromatography and HPLC analysis. By chromatographic separation and spectroscopic analysis, 8 compounds, such as 1,9-dimethylguanine (1), adenosine (2), uridine (3), nicotinamide (4), 3-methyluracil (5), 1,7-dimethylxanthine (6), nudifloric acid (7), and mannitol (8) were identified from 6 different fractions and 4 more subfractions...

Hirsutella sinensis is considered as the only correct anamorph of Ophiocordyceps sinensis. To improve cordycepin and cordycepic acid production in H. sinensis, the biosynthetic pathways of cordycepin and cordycepic acid were predicted, and verified by cloning and expressing genes involved in these pathways, respectively. Then, 5'-nucleotidase participating in biosynthetic pathway of cordycepin, hexokinase, and glucose phosphate isomerase involved in biosynthetic pathway of cordycepic acid, were demonstrated playing important roles in the corresponding biosynthetic pathway by real-time PCR, accompanying with significantly up-regulated 15...

An exopolysaccharide (EPS) was fractionated from fermentation media of a Cordyceps sinensis fungus (Cs-HK1) by ethanol precipitation at 2/5 volume ratio of ethanol/media. Its structural characteristics were elucidated by FT-IR, GC, GC-MS, 1D and 2D NMR combined with periodate oxidation, Smith degradation, partial acid hydrolysis, and methylation analysis. Furthermore, the immunomodulatory activity of EPS was evaluated by the model of cyclophosphamide-induced immunosuppression. The results from monosaccharide composition and partial acid hydrolysis indicated that EPS almost consisted of glucose excluding a trace amount of mannose...

In this work MALDI-TOF mass spectroscopy was investigated to characterise the β-glucan profiles of several commercial health supplements, without any derivatisation or purification pre-treatment. The effect of two solvents (water and dimethyl sulfoxide) and two MALDI matrices (2,5-dihydroxybenzoic acid and 2',4',6'-trihydroxyacetophenone) was first evaluated on dextran standards. MALDI-TOF was found as a useful and quick technique to obtain structural information of diverse food supplements based on mushroom extracts...

BACKGROUND: Nucleosides are supportive in the regulation and modulation of various physiological processes in body, they acts as precursors in nucleic acid synthesis, enhance immune response, help in absorption of iron and influence the metabolism of fatty acids. Cordyceps sinensis and Ganoderma lucidum are well-known for its use in traditional medicine of China, Nepal and India. They are rich in nucleosides such as adenine, adenosine, cordycepin, etc. Hence, a simple, economic and accurate high-performance liquid chromatography (HPLC) analytical method was proposed for determination of adenine and adenosine for the quality control of plants...

Here, we compare the fungal community composition and diversity in Amazonian Dark Earth (ADE) and the respective non-anthropogenic origin adjacent (ADJ) soils from four different sites in Brazilian Central Amazon using pyrosequencing of 18S ribosomal RNA (rRNA) gene. Fungal community composition in ADE soils were more similar to each other than their ADJ soils, except for only one site. Phosphorus and aluminum saturation were the main soil chemical factors contributing to ADE and ADJ fungal community dissimilarities...

In this study, using standard methods, mycelial nutrients, bioactive compounds, and antioxidants were analyzed for the first time for five fungal species: Isaria sinclairii (Berk.) Lloyd, I. tenuipes Peck, I. japonica Yasuda, I. farinosa (Holmsk) Fr. and Cordyceps tuberculata (Lebert) Maire. All of these species were low in fat content and rich in protein, fiber, ash, and carbohydrates. Mineral elements (Fe, Mg, Cu, Mn, and Ca) were detected in appreciable amounts. All three types of fatty acids (saturated, monounsaturated, and polyunsaturated) as well as bioactive compounds (ascorbic acid, β-carotene, lycopene, phenolic compounds, and polysaccharides) were detected for each species...
