Alkylating Agents as Environmental Carcinogen & Chemotherapy


Generic Leukeran Chlorambucil - Cancer -

Alkylating agents are a class of antineoplastic or anticancer drugs which act by inhibiting the transcription of DNA into RNA and thereby stopping the protein synthesis. Alkylating agents substitute alkyl groups for hydrogen atoms on DNA, resulting in the formation of cross links within the DNA chai … The alkylating agents are antitumor drugs that act through the covalent binding of alkyl groups to cellular molecules. This binding is mediated by reactive intermediates formed from a more parent alkylating compound. Historically, the alkylating agents have played an important role in the development of cancer chemotherapy. Alkylating agents throw a monkey-wrench into the cell’s DNA machinery.

Alkylating agents • Alkylating agents produce highly reactive carbonium ion intermediates or related transition complex which transfer alkyl group to cellular macromolecules by covalent bonds. • Alkylating agents cross link with carboxyl, hydroxyl, amino, sulfhydryl and phosphate groups of biomacromolecules results abnormal base paring/ scission of DNA Stand. Summary: The protein encoded by this gene is involved in the efficient repair of DNA single-strand breaks formed by exposure to ionizing radiation and alkylating agents.

Alkyl groups can also be removed in a process known as dealkylation. Alkylating agents are often classified according to their nucleophilic or electrophilic character. 1. Cancer Chemother Biol Response Modif. 1991;12:27-42.

Classification of Alkylating Agents One can separate different alkylating agents into 3 categories which depend on the conditions of Alkylating agents have the ability to add alkyl groups to many electronegative groups under conditions present in cells. They stop tumor growth by introducing single strand breaks as well as by cross‐linking nucleotides in DNA double‐helix strands – directly attacking DNA. Alkylating Agents - Science topic Highly reactive chemicals that introduce alkyl radicals into biologically active molecules and thereby prevent their proper functioning. Many are used as Many of these comprise drugs that currently form part of the combinations used to treat neoplastic disease.
