Pimavanserin is an approved selective 5-HT2A receptor inverse agonist for treating Parkinson’s disease psychosis. However, few studies on its metabolism in vitro have been investigated. In this research, eight strains of fungi are used to study the pimavanserin profiles and six them demonstrated positive transformation results. Factors influencing rate, like substrate concentration, culture tim...
The metabolism of phenanthrene by the fungus Cunninghamella elegans was investigated. Kinetic experiments using [9-14C]phenanthrene showed that after 72 h, 53% of the total radioactivity was associated with a glucoside conjugate of 1-hydroxyphenanthrene (phenanthrene 1-O-beta-glucose). This metabolite was isolated by reversed-phase high-performance liquid chromatography and characterized by the...
Pulmonary mucormycosis (PM) is a life-threatening fungal infection in patients with hematologic malignancies, and early and accurate diagnostic modalities are urgently needed. We conducted a polymerase chain reaction (PCR) assay targeting these fungi in peripheral blood from four patients with hematologic malignancies who were strongly suspected of having PM. In these four patients, the Rhizopu...
A cymene-derived drug, 3-[4'-(o-ethoxyphenyl)piperazin-1'-yl]-ethyloxy-p-cymene+ ++ (B1178), is not significantly metabolized by fungal microorganisms. On the contrary, one of its metabolites in rat, 3-(piperazin-1'-yl)ethoxy-p-cymene (B1071), is quantitatively converted by Cunninghamella echinulata NRRL 3655 into two hydroxylated products: the corresponding phenol derivative and a benzylic alc...
Isosteviol (1) has been reported to exhibit moderate vasorelaxant activity. In order to enhance the bioactivity of this compound, chemical modification of 1 to the dihydro analog, ent-16β-hydroxybeyeran-19-oic acid (2), was undertaken. Compound 2 was then converted to the corresponding acetate derivative, ent-16β-acetoxybeyeran-19-oic acid (3). Biotransformation of compounds 1-3 by the fungus C...
The biosorption of three reactive azo dyes (red, black and orange II) found in textile effluents by inactive mycelium of Cunninghamella elegans has been investigated. It was found that after 120 hours of contact the adsorption led to 70%, 85%, 93% and 88% removal of reactive orange II, reactive black, reactive red and a mixture of them, respectively. The mycelium surface was found to be selecti...
