Hydroxylation of the herbicide isoproturon by fungi isolated from agricultural soil.
Several asco-, basidio-, and zygomycetes isolated from an agricultural field were shown to be able to hydroxylate the phenylurea herbicide isoproturon [N-(4-isopropylphenyl)-N',N'-dimethylurea] to N-(4-(2-hydroxy-1-methylethyl)phenyl)-N',N'-dimethylurea and N-(4-(1-hydroxy-1-methylethyl)phenyl)-N',N'-dimethylurea. Bacterial metabolism of isoproturon has previously been shown to proceed by an in...
متن کاملO-demethylation and sulfation of 7-methoxylated flavanones by Cunninghamella elegans.
Metabolism of 7-O-methylnaringenin (sakuranetin) by Cunninghamella elegans NRRL 1392 yielded naringenin and naringenin-4'-sulfate. C. elegans also converted 5, 3', 4'-trihydroxy-7-methoxyflavanone into eriodictyol-4'-sulfate. Furthermore, incubation of 5, 4'-dihydroxy-7, 3'-dimethoxyflavanone with the same fungus gave homoeriodictyol (5, 7, 4'-trihydroxy-3'-methoxyflavanone) and homoeriodicytol...
متن کاملCarbazole hydroxylation by the filamentous fungi of the Cunninghamella species
Nitrogen heterocyclic compounds, especially carbazole, quinolone, and pyridine are common types of environmental pollutants. Carbazole has a toxic influence on living organisms, and the knowledge of its persistence and bioconversion in ecosystems is still not complete. There is an increasing interest in detoxification of hazardous xenobiotics by microorganisms. In this study, the ability of thr...
متن کاملBiotransformation of mirtazapine by Cunninghamella elegans.
The fungus Cunninghamella elegans was used as a microbial model of mammalian metabolism to biotransform the tetracyclic antidepressant drug mirtazapine, which is manufactured as a racemic mixture of R(-)- and S(+)-enantiomers. In 168 h, C. elegans transformed 91% of the drug into the following seven metabolites: 8-hydroxymirtazapine, N-desmethyl-8-hydroxymirtazapine, N-desmethylmirtazapine, 13-...
متن کاملTransformation of amoxapine by Cunninghamella elegans.
We examined Cunninghamella elegans to determine its ability to transform amoxapine, a tricyclic antidepressant belonging to the dibenzoxazepine class of drugs. Approximately 57% of the exogenous amoxapine was metabolized to three metabolites that were isolated by high-performance liquid chromatography and were identified by nuclear magnetic resonance and mass spectrometry as 7-hydroxyamoxapine ...
