  Effects of oligofluorine substitution on the mutagenicity of quinoline: a study with twelve fluoroquinoline derivatives

  摘要：

  A total of 12 variously fluorinated derivatives of quinoline (Q) were tested for their mutagenicity in Salmonella typhimurium TA100 in the presence of S9 mix to investigate the structure-mutagenicity relationship in oligofluorinated quinolines. Nine of them, 3,7-di-, 5,6-di-, 6,7-di-, 6,8-di-, 7,8-di-, 3,5,7-tri-, 5,6,8-tri-, 6,7,8-tri-, and 5,6,7,8-tetrafluoroquinolines (FQs), were newly synthesized for this purpose. Those fluorinated at position 3 were all non-mutagenic. Mutagenicity was enhanced by fluorine-substitution at position 5 or 7, but not in 3-FQs (i.e., 3,5-di-, 3,7-di-, and 3,5,7-triFQs). Some of the 6-fluorinated derivatives showed less maximum induced-revertants with more mutagenic potencies in terms of induced-revertants per dose than quinoline. No marked change occurred by fluorine-substitution at position 8. These results show that the effect of di- and trifluoro-substitution on mutagenicity is generally additive, while that of tetrafluorination approaches the deactivating effect of perfluorination. Our study suggests that 3-fluorine-substitution in the pyridine moiety may be a useful means of antimutagenic structural modification in pyridine-fused aromatic chemicals for medicinal and agricultural use.
