Ethylating
WebMethylating and ethylating agents are among the most extensively studied DNA alkylating carcinogens, and serve as models in studies of DNA alkylation, mutagenesis, and carcinogenesis. Large numbers of structurally diverse chemicals are capable of DNA methylation or ethylation reactions, including alkyl sulfates, alkyl alkanesulfonates ...
