Of the seven Streptomyces spp. examined, all but one transformed flurbiprofen to the main mammalian metabolite 4′-hydroxyflurbiprofen 2, and the majority also produced 3′,4′-dihydroxyflurbiprofen 3. Three strains, Streptomyces griseus DSM40236 and ATCC13273, and Streptomyces subrutilis DSM40445, also elaborated 3′-methoxy, 4′-hydroxy-flurbiprofen 4. None of the Bacillus spp. examined yielded these metabolites. Examination of the extracted supernatants of Streptomyces lavenduligriseus and Streptomyces rimosus by fluorine-19 nuclear magnetic resonance (19F NMR), indicated new resonances and these new fluorometabolites were purified by HPLC and revealed to be flurbiprofenamide 5 and 7-hydroxyflurbiprofenamide 6 after MS and NMR analyses. Subsequent re-examination of the culture supernatants from Bacillus subtilis IM7, Bacillus megaterium NCIMB8291 and B. megaterium ATTC14581 showed that these strains also produced 5 and 6. Resting cell investigations suggested that the amidation reaction employed nitrogen from an as yet unidentified amino acid.||Type of material:||Journal Article||Publisher:||Elsevier||Copyright (published version):||2011 Elsevier B.V.||Keywords:||F-19 NMR;Biotransformation;Fluorometabolite||DOI:||10.1016/j.molcatb.2011.05.008||Language:||en||Status of Item:||Peer reviewed|
