32P-postlabeling analysis of binding of the cyclophosphamide metabolite, acrolein, to DNA.


The cyclophosphamide metabolite, acrolein, was reacted with 2'-deoxyguanosine-3'-monophosphate, and two adducts were detected by high performance liquid chromatography and 32P-postlabeling assay. These adducts were resistant to dephosphorylation by nuclease P1 and could be isolated and detected from calf thymus DNA that had been reacted in vitro with… (More)
