Roles (2)

RoleDescription
alkylating agentHighly reactive chemical that introduces alkyl radicals into biologically active molecules and thereby prevents their proper functioning. It could be used as an antineoplastic agent, but it might be very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. It could also be used as a component of poison gases.
antineoplastic agentA substance that inhibits or prevents the proliferation of neoplasms.
