the present investigation was aimed at studying the effect of incubation period, media, vitamins and solvents on biotransformation of albendazole by cunninghamella blakesleeana. the transformation was evaluated and identified by high performance liquid chromatography (hplc) and the structures of the transformed products were assigned by liquid chromatography-tandem mass spectrometry (lc/ms/ms) ...

Structural transformation of ezetimibe was performed by fungi Beauvaria bassiana and Cunninghamella blakesleeana. The metabolites were identified by different spectroscopic techniques as (3R,4S)-1-(4-fluorophenyl)-3-((E)-3-(4-fluorophenyl) allyl)-4-(4-hydroxyphenyl) azetidin-2-one (2), (3R, 4S)-1-(4-fluorophenyl)-3-(3-(4fluorophenyl)-3-oxopropyl)-4-(4-hydroxyphenyl) azetidin-2-one (3), (3R,4S) ...

Microbial steroid biotransformation have found wide-reaching application for the production of more precious and functionalized compounds due to their high regio-and stereoselectivity. In this study, the possibility of using filamentous fungi Aspergillus brasiliensis cells in the biotransformation of progesterone (I), a C-21 steroid hormone was studied for the first time.The fungal strain was i...

A detailed study of the biotransformation of 6- and 7-methoxyflavones by four fungal strains (Aspergillus niger strains MB, KB, and SBP; Penicillium chermesinum 113) was carried out. Products of demethylation and also demethylation combined with hydroxylation at C-4' were identified. The biotransformation products were stronger antioxidants than the substrates.

The fungus Cunninghamella elegans was used to biotransform 6-nitrochrysene, a mutagen that is a widespread environmental contaminant. After 6 days, 74% of the 3H-labeled 6-nitrochrysene added had been metabolized to two isomeric sulfate conjugates. These conjugates were separated by high-performance liquid chromatography and identified by UV-visible, 1H nuclear magnetic resonance, and mass spec...
