Definition of the noun alkylating agent

What does alkylating agent mean as a name of something?


  1. an antineoplastic drug used to treat some forms of cancer


  1. Alkylating agent are so named because of their ability to add alkyl groups to many electronegative groups under conditions present in cells. They stop tumour growth by cross-linking guanine nucleobase in DNA double-helix strands - directly attacking DNA. This makes the strands unable to uncoil and separate. As this is necessary in DNA replication, the cells can no longer divide. These drugs act nonspecifically. Some of them require conversion into active substances in vivo.
  2. Alkylating Agent: Agents that replace hydrogen atom in biologically active molecules with alky radical, hindering proper function. Alkylating agents exhibit cytotoxic effects through the alkylation of DNA, resulting in strand cross-linking, ultimately inhibiting DNA replication and cell growth.
