Abstract
Rats treated with di(2-chloroethyl)methylamine (HN2), N-methyl-N-nitrosourea (MNUA) and N-ethyl-N-nitrosourea (ENUA) excrete significantly larger amounts of deoxycytidine (dC) and thymidine in their urine 0-24 h after treatment. Ethyl methanesulphonate (EMS) and dimethylnitrosamine (DMN) gave negative results in this respect but all five alkylating agents increased the excretion of 1-methyl-nicotinamide (1-meNmd). In addition, a larger quantity of 7-methylguanine (7MG) and uric acid was excreted after DMN treatment. 1,4-Dimethanesulphonoxybutane (myleran), 2,2-dichlorovinyl dimethyl phosphate (dichlorvos), 5-fluorouracil (5FU), cytosine arabinoside (araC), 2-acetylaminofluorene (AAF) and 7-bromomethylbenz-[a]anthracene (7-BrMBA) gave negative results.
