NCIt definition : The 2-chloroethyl ester of (methylsulfonyl) methanesulfonic acid with potential antineoplastic
effects. Acting as a chloroethylating agent, clomesone induces the formation of DNA
interstrand crosslinks in some cell lines, and exhibits antitumor activity in some
animal models. Alkylating agents exert cytotoxic and, in some cases, chemotherapeutic
effects by transferring alkyl groups to DNA, thereby damaging DNA and interfering
with DNA synthesis and cell division. (NCI04);
