Parasitical: A New Metabolite from Aspergillus parasiticus
Parasiticol, a metabolite structurally related to the aflatoxins, has been isolated and characterized. The compound is elaborated by several strains of the Aspergillus jiaDus series previously shown to be aflatoxin producers. The metabolite was separated and purified by chromatography Oll three columns (silicic acid, silica gel, and alumiua) followed by recrystallization from chlorofom,-bexane....
متن کاملCyclogregatin, a new metabolite from Aspergillus panamensis.
During the course of the isolation of gregatin A (1) from submerged cultures of Aspergillus panamensis a new tetronic acid derivative was obtained. According to its cyclic structure this compound was named cyclogregatin (2). In the following the structural elucidation and the biological activities of 2 in comparison with gregatin A will be described. A. panamensis, CBS120.45, was cultivated as ...
متن کاملAsperfuran, a novel antifungal metabolite from Aspergillus oryzae.
Asperfuran is a novel antifungal dihydrobenzofuran derivative produced by a strain of Aspergillus oryzae. Asperfuran weakly inhibited chitin synthase from Coprinus cinereus. This inhibition could be abolished by the addition of egg lecithin. In the agar diffusion assay asperfuran induced morphological changes in Mucor miehei at very low concentrations (20 ng/disc) while growth was only partly i...
متن کاملToxic metabolite produced by Aspergillus wentii.
Mycelial extracts of an Aspergillus wentii strain grown on yeast-extract sucrose medium and initially isolated from country-cured ham were highly toxic when inoculated into chicken embryos or fed to mice. Moldy corn and rice were less toxic when fed to mice. Water extracts of moldy corn or rice or culture filtrates from yeast-extract sucrose medium were not toxic. Purification by thin-layer chr...
متن کاملA Novel Function for Kojic Acid, a Secondary Metabolite from Aspergillus Fungi, as Antileishmanial Agent
Kojic acid (KA) is a fungal metabolite used as a topical treatment skin-whitening cosmetic agent for melasma in humans; however its potential as an anti-leishmanial agent is unknown. Chemotherapy is one of the most effective treatments for Leishmaniasis. However, the drugs available are expensive, invasive, require long-term treatment and have severe side effects. Thus, the development of new e...
