Many mutagens are alkylating agents. This means that they will add an alkyl group, such as methyl or ethyl, to a base in DNA. Examples of commonly used alkylating agents in laboratory work are N-methyl-nitrosoguanidine and N-methyl-N'-nitro-nitrosoguanidine (MNNG, Figure 7.9.A.).

Often, alkylation requires a catalyst. Common alkylating catalysts are acids, such as HF or H 2 SO 4. Cyclosporamide is a classical example of the role of the host metabolism in the activation of an alkylating agent and is one or the most widely used agents of this class.

Nucleophilic alkylating agents. Examples include the use of organometallic compounds such as Grignard (organomagnesium), organolithium, organocopper, and organosodium reagents.These compounds typically can add to an electron-deficient carbon atom such as at a carbonyl group. Many mutagens are alkylating agents.

Mustard gases used during the First World War are an example of alkylating agents. Alkylating agents form highly reactive intermediate compounds that are able to transfer alkyl groups to DNA. Alkylation can result in miscoding of DNA strands, incomplete repair of alkylated segments (which leads to strand breakage or depurination), excessive cross-linking of DNA, and inhibition of strand separation at mitosis.

Some examples of alkylating agents are nitrogen mustards (chlorambucil and cyclophosphamide ), cisplatin, nitrosoureas (carmustine, lomustine, and semustine), alkylsulfonates (busulfan), ethyleneimines (thiotepa), and triazines (dacarbazine).

Alkylating agents, for example nitrogen "mustards", are variably toxic, mutagenic, carcinogenic and teratogenic, but by mechanisms which have not been clearly established.

alkylbenzene sulfonate. See More Nearby Entries Alkylating agents substitute alkyl groups for hydrogen atoms on DNA, resulting in the formation of cross links within the DNA chain and thereby resulting in cytotoxic, mutagenic, and carcinogenic effects. This action occurs in all cells, but alkylating agents have their primary effect on rapidly dividing cells which do not have time for DNA repair. progression following bifunctional alkylating agent treatment and correlate the changes with cytotoxicity and DNA damage. Using a variety of cell types, both mono- and bifunctional alkylating agents, and drugs which modify the DNA damage and toxicity of the alkylating agents, we will be It is also possible for nucleophilic groups in proteins to react with alkylating agents, giving the class of drugs selectivity problems. Drugs that possess two electrophilic groups can react with the opposing strand of DNA causing crosslinking.
