Abstract

Hycanthone methanesulfonate (HCT) was shown to induce "forward" and "reverse" mutations in Salmonella typhimurium and Escherichia coli. Mutational effects of HCT on S. tyhhimurium TA1532 were concentration and time dependent. A comparison of mutagenic potency for TA1532 was made between HCT and the frame-shift mutagens quinacrine and ICR-191. An investigation of structure-activity relationships revealed the substituent in the 4-position of ring A to be critical for mutagenicity. Activity was found when this group was a hydroxymethyl (i.e., HCT) or an aldehyde (Win 25,315), but the analogues having a carboxyl group (Win 25,850) or methyl group (lucanthone) in this positionwere inactive. Removal of a single ethyl group from the side chain did not affect mutagenic activity inasmuch as the potency of desethyl HCT (Win 27,262) equaled that of HCT on a molar basis. A marginal activity was found with a sample of HCT sulfoxide (win 27,266), but this sample was found to contain traces of HCT. The HCT analogue with a terminal N-oxide in the side chain (Win 29,329) was inactive at the concentration tested.
