    Incorporation of fluorine into an organic compound can favourably alter its physicochemical properties with respect to biological activity, stability and lipophilicity. Accordingly, this element is found in many pharmaceutical and industrial chemicals. Organofluorine compounds are accepted as substrates by many enzymes, and the interactions of microorganisms with these compounds are of relevance to the environment and the fine chemicals industry. One the one hand the microbial transformation of fluorinated compounds can lead to the generation of toxic compounds that are of environmental concern, yet similar biotransformations can yield difficult-to-synthesise products and intermediates, in particular derivatives of biologically active secondary metabolites. In this paper we review the historical and recent developments of organofluorine biotransformation in microorganisms, and highlight the possibility of using microbes as models of fluorinated drug metabolism in mammals.

    Biotransformation of fluorobiphenyl by Cunninghamella elegans

    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- and dihydroxylated compounds were detected in organic extracts by gas chromatography–mass spectrometry. Additionally, fluorinated water-soluble products were detected by 19F NMR and were identified as sulphate and β-glucuronide conjugates. Other fluorobiphenyls (2-fluoro-, 4,4′-difluoro- and 2,3,4,5,6-pentafluoro-biphenyl) were catabolised by C. elegans, yielding mono- and dihydroxylated products, but phase II metabolites were detected from 4,4′-difluorobiphenyl only.
