Induction of sister-chromatid exchanges in L1210 leukemia cells by new antitumor 2-haloethyl(methylsulfonyl) methanesulfonate compounds
1988
Abstract The antitumor 2-halo(chloro, bromo, and fluoro)-ethyl(methylsulfonyl) methanesulfonates, ethyl(methylsulfonyl) methanesulfonate, and chlorozotocin, a 2-chloroethylnitrosourea, were evaluated for their potential to induce SCEs in L1210 cells. The results indicate that all the compounds induced approximately 2-fold or greater increases in SCEs in a dose-related manner. 2-Chloroethyl(methylsulfonyl) methanesulfonate, a DNA-interacting agent and a drug selected for clinical trials, exhibited the highest SCE increase in these cells.
