Enzymkatalysierte späte Modifizierungen: Besser spät als nie

Angewandte Chemie, Volume 133, Issue 31, Page 16962-16993, July 26, 2021., 2021
Späte Modifizierungen sind unerlässlich für die Diversifizierung von Verbindungen in der Synthese. Da Enzyme effiziente Werkzeuge für milde, Katalysator‐kontrollierte Funktionalisierungen bieten, sind neue biokatalytische Methoden für eine große Fülle orthogonaler Reaktionen entstanden.

Biotransformation of fluorobiphenyl by Cunninghamella elegans

Applied Microbiology and Biotechnology, 2009
The fungus Cunninghamella elegans is a useful model of human catabolism of xenobiotics. In this paper, the biotransformation of fluorinated biphenyls by C. elegans was investigated by analysis of the culture supernatants with a variety of analytical techniques. 4-Fluorobiphenyl was principally transformed to 4-fluoro-4'-hydroxybiphenyl, but other mono-

Ametryn removal by Metarhizium brunneum: Biodegradation pathway proposal and metabolic background revealed [PDF]

, 2018
Ametryn is a representative of a class of s-triazine herbicides absorbed by plant roots and leaves and characterized as a photosynthesis inhibitor. It is still in use in some countries in the farming of pineapples, soybean, corn, cotton, sugar cane or ...

Biotransformation of fluorene by the fungus Cunninghamella elegans [PDF]

Applied and Environmental Microbiology, 1993
The metabolism of fluorene, a tricyclic aromatic hydrocarbon, by Cunninghamella elegans ATCC 36112 was investigated. Approximately 69% of the [9-14C]fluorene added to cultures was metabolized within 120 h. The major ethyl acetate-soluble metabolites were 9-fluorenone (62%), 9-fluorenol, and 2-hydroxy-9-fluorenone (together, 7.0%). Similarly to bacteria,

Rapid method for Mycobacterium tuberculosis identification using electrospray ionization tandem mass spectrometry analysis of mycolic acids [PDF]

, 2013
Mycolic acids (MAs), which play a crucial role in the architecture of mycobacterial cell walls, were analyzed using electrospray ionization tandem mass spectrometry. A targeted analysis based on the 10 most abundant and characteristic multiple reaction

Biotransformation of chlorpromazine and methdilazine by Cunninghamella elegans [PDF]

Applied and Environmental Microbiology, 1996
When tested as a microbial model for mammalian drug metabolism, the filamentous fungus Cunninghamella elegans metabolized chlorpromazine and methdilazine within 72 h. The metabolites were extracted by chloroform, separated by high-performance liquid chromatography, and characterized by proton nuclear magnetic resonance, mass, and UV spectroscopic ...
