Metabolic scheme for PRA in G. striatum. Degradation routes were initiated by oxidative decarboxylation (A), defluorination (B), hydroxylation of position C-8 (C), and decomposition of the amine moiety (D) which, alternatively, could be eliminated intact as F-10. Hypothetical intermediates are marked in grey: twofold oxidation of the pyrogallol-type intermediate is likely to provide a cis,cis-muconic acid-type metabolite, from which F-13 may be formed after two spontaneous decarboxylations.
