Antibiotic Substances from Basidiomycetes: III. Coprinus Similis and Lentinus Degener.

THE CHEMICAL NATURE OF THE MELANINS FROM Coprinus spp

Among the Basidiomycetes the species of the genus Coprinus have black spores and hymenia that, at maturity, are transformed through autodigestion into a black or inky fluid that drops from the pileus and blackens the soil beneath the fruiting structures. The melanins from three different species of Coprinus have been characterized by spectroscopic techniques, including cross-polarization, magic...

Antibiotic Substances from Basidiomycetes Ix

Antibiotics from basidiomycetes. XXXVIII. 2-Methoxy-5-methyl-1,4-benzoquinone, a thromboxane A2 receptor antagonist from Lentinus adhaerens.

In the course of our screening for antithrombotic compounds using platelet rich plasma from bovine slaughter blood, 2-methoxy-5-methyl-1,4-benzoquinone (1) has been isolated from mycelial cultures of Lentinus adhaerens. The compound inhibits the U46619-induced aggregation of human blood platelets with an IC50 of 2.5 micrograms/ml (16.45 microM) and is a new thromboxane A2 receptor antagonist. T...

A Comparison of Antinociceptive Activity of Mycelial Extract from Three Species of Fungi of Basidiomycetes

The antinociceptive activity of mycelial extract from fermented mushroom of Ganoderma lucidum Coprinus comatus and Grifola frondosa were studied in this paper. The writhing test, formalin test and hot-plate test were used to evaluate the antinociceptive activity of the acetone extracts of the three Species of Fungi of Basidiomycetes in the study respectively. The extract of Ganoderma lucidum in...

Screening of Lignocellulose-Degrading Superior Mushroom Strains and Determination of Their CMCase and Laccase Activity

In order to screen lignocellulose-degrading superior mushroom strains ten strains of mushrooms (Lentinus edodes939, Pholiota nameko, Lentinus edodes868, Coprinus comatus, Macrolepiota procera, Auricularia auricula, Hericium erinaceus, Grifola frondosa, Pleurotus nebrodensis, and Shiraia bambusicola) were inoculated onto carboxymethylcellulose agar-Congo red plates to evaluate their ability to p...
