Comparison of the mutagenic activity of 5-hydroxymethyldeoxyuridine with 5-substituted 2'-deoxyuridine analogs in the Ames Salmonella/microsome test. 1986

M H Bilimoria, and S V Gupta

4 antiviral drugs 5-hydroxymethyldeoxyuridine (HMUdR), 5-trifluorothymidine (F3TdR), 5-methoxymethyldeoxyuridine (MMUdR) and 5-ethyldeoxyuridine (EtUdR) have been evaluated for mutagenic activity in the Ames Salmonella/microsome test. The antimetabolites F3TdR and HMUdR were mutagenic in a dose-dependent manner in strain TA100. F3TdR also was mutagenic in strain TA1535. Rat-liver post-mitochondrial supernatant (S9) was not required for mutagenicity.
