Abstract

The substituted base, 6-(β-hydroxyethyl)guanine, has been identified in DNA which has been treated with the antitumor agent, N,N¹-bis(2-chloroethyl)-N-nitrosourea (BCNU). This finding provides support for the suggestion that interstrand crosslinks may involve substitution at this position. The presence of 6-hydroxyethylguanine in DNA could also explain the carcinogenic potential of the haloethyl nitrosoureas since this DNA modification is considered mutagenic.
