Anti-influenza virus polyketides from the acid-tolerant fungus Penicillium purpurogenum JS03-21.
Fractionation of the ethyl acetate extract of an acid-tolerant fungus, Penicillium purpurogenum JS03-21, resulted in the isolation of six new compounds, purpurquinones A-C (1-3), purpuresters A and B (4 and 5), and 2,6,7-trihydroxy-3-methylnaphthalene-1,4-dione (6), together with three known compounds, TAN-931 (7), (-)-mitorubrin (8), and orsellinic acid. The structures of 1-6 were elucidated p...
متن کاملProduction of ß-glucosidase by Penicillium Purpurogenum
The fungus Penicillium purpurogenum was found to produce intracellular ß-glucosidase. Maximum activity of ß-glucosidase was observed on sucrose. Various cultural parameters of cultivation of P. purpurogenum for production of ß-glucosidase were optimized. Maximum enzyme content was observed after 96 hours of cultivation at 30°C. Addition of amino acids histidine and cysteine induced ß-glucosidas...
متن کاملRare Chromones from a Fungal Mutant of the Marine-Derived Penicillium purpurogenum G59
Three new and rare chromones, named epiremisporine B (2), epiremisporine B1 (3) and isoconiochaetone C (4), along with three known remisporine B (1), coniochaetone A (5) and methyl 8-hydroxy-6-methyl-9-oxo-9H-xanthene-1-carboxylate (6) were isolated from a mutant from the diethyl sulfate (DES) mutagenesis of a marine-derived Penicillium purpurogenum G59. The structures of 2-4 including the abso...
متن کاملCloning and high-level expression of alpha-galactosidase cDNA from Penicillium purpurogenum.
The cDNA coding for Penicillium purpurogenum alpha-galactosidase (alphaGal) was cloned and sequenced. The deduced amino acid sequence of the alpha-Gal cDNA showed that the mature enzyme consisted of 419 amino acid residues with a molecular mass of 46,334 Da. The derived amino acid sequence of the enzyme showed similarity to eukaryotic alphaGals from plants, animals, yeasts, and filamentous fung...
متن کاملProduction of rubratoxin B by Penicillium purpurogenum Stoll.
Culture filtrates and chloroform extracts from Penicillium purpurogenum isolated from foodstuffs were subjected to preliminary survey for toxic effects on HeLa cells and mice. The toxic metabolite was isolated in a crystalline form from P. purpurogenum and was identified as rubratoxin B. Pathological findings observed in HeLa cells and mice treated with the metabolite are briefly described.
