Fluoro-A-85380 demonstrated no mutagenic properties in in vivo rat micronucleus and Ames tests

The potential mutagenic properties (micronucleus and the Ames tests) of fluoro-A-85380 (2-fluoro-3-[2(S)-2-azetidinylmethoxy]pyridine) were evaluated as a mandatory pre-clinical step. No statistically significant increase in the frequency of micronucleated polychromatic erythrocytes was found in animals treated at any dose tested. No biologically significant increase in the mean number of revertants was noted in all the Salmonella typhimurium strains tested with fluoro-A-85380. Therefore, fluoro-A-85380 demonstrated no mutagenic properties using these two tests.
