Inactivation of alkyltransferase in HT29 cells. Panel A shows the loss of alkyltransferase (hAGT) activity as a function of time after addition of the compound indicated to cultures of HT29 cells. Panel B shows the effect of exposing HT29 cells to the compound indicated for 2 h prior to the addition of 40 μM BCNU. Cell survival was then measured using a colony forming assay as described in the Experimental Section.
