MeSH Heading: Alkylating Agents
Tree Number(s): D27.505.519.124; D27.888.569.035
Unique ID: D000477
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D000477
Scope Note: Highly reactive chemicals that introduce alkyl radicals into biologically active molecules and thereby prevent their proper functioning. Many are used as antineoplastic agents, but most are very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. They have also been used as components in poison gases.
