Reverse mutation (Ames) tests with Salmonella typhimurium TA98, TA100 and TA1537, and chromosomal aberration tests in vitro with a Chinese hamster fibroblast cell line (CHL), were carried out on fluorinated pyrimidine derivatives, such as 5-fluorouracil (5-FU), 1-(2-tetrahydrofuryl)-5-fluorouracil (FT), 5-fluorodeoxyuridine (FUdR), 1,3-bis(2-tetrahydrofuryl)-5-fluorouracil (FD-1) and a mixture of uracil and FT in the molar ratio 4 : 1 (UFT) (Fujii et al., 1978). For comparison, similar tests were also carried out on 4 anti-metabolic agents, a metabolite of FD-1 and a component of UFT, such as cytosine-1-beta-D-arabinofuranoside (AraC), 6-mercaptopurine (6-MP), 6-thioguanine (6-TG), 8-azaguanine (8-AG), 3-(2-tetrahydrofuryl)-5-fluorouracil (3-FT) and uracil. The anti-bacterial action of 4 fluorinated pyrimidine derivatives such as 5-FU, FT, FD-1 and UFT to TA100 was tested under the condition that buffer, S9 mix, S9 and albumin were present. 6-MP was only positive in the Ames test with TA100 in the system without S9 mix, while all others failed to show mutagenic activity. On the other hand, all compounds tested, except uracil, induced chromosomal aberrations on CHL cells in the system without metabolic activation. FT was degraded by S9, but there was no significant difference in the killing activity of FT among with buffer, S9 mix and albumin. The killing activity of 5-FU was the strongest with buffer, and it was slightly binding to albumin. The killing activity of 5-FU was mostly decreased by S9 mix. FD-1 showed the strongest anti-bacterial action when S9 mix was present but it was degraded by S9. UFT showed no anti-bacterial action in any conditions.
