An alkylating agent is any chemical substance that will add an alkyl group to another molecule in the chemical reaction known as alkylation. An alkyl group is basically a chain of CH 2 units of any length capped with a terminal hydrogen atom, so an alkylation reaction is simply the addition of an alkyl chain to another molecule.
Alkylating agents are highly reactive compounds. They covalently bind to nucleophilic groups of cellular constituents such as DNA, RNA and proteins, in a process called alkylation. They are generally cytotoxic, mutagenic and carcinogenic. Alkylating agents are not only used to treat cancer, but they can also cause cancer.

The majority of these drugs cause myelosuppression and mucositis as their primary acute toxicities, as well as delayed pulmonary fibrosis and late secondary leukemias. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators 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. 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.

Alkylating agents throw a monkey-wrench into the cell’s DNA machinery. Cancer cells are sensitive to DNA damage. Alkylating agents work by reacting with the proteins that bond together to form the very delicate double helix structure of a DNA molecule, adding an alkyl group to some or all of them.
Alkylating agents are not only used to treat cancer, but they can also cause cancer. Alkylating Agents Alkylerande medel Svensk definition. Starkt reaktiva kemiska substanser som för in alkylradikaler i biologiskt aktiva molekyler och hindrar deras rätta funktion. Många används som antitumörmedel, men de flesta är mycket giftiga, med carc inogen, mutagen, teratogen eller immunsuppressiv verkan.
15 Jan 2015 The alkylating agents exert their antineoplastic actions by generating highly reactive carbonium ion intermediates that form a covalent linkage
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.
From Wikipedia, the free encyclopedia An alkylating antineoplastic agent is an alkylating agent used in cancer treatment that attaches an alkyl group (C n H 2n+1) to DNA. The alkyl group is attached to the guanine base of DNA, at the number 7 nitrogen atom of the purine ring. Alkylating agent, any highly reactive drug that binds to certain chemical groups (phosphate, amino, sulfhydryl, hydroxyl, and imidazole groups) commonly found in nucleic acids and other macromolecules, bringing about changes in the DNA and RNA of cells. 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 are highly reactive compounds. They covalently bind to nucleophilic groups of cellular constituents such as DNA, RNA and proteins, in a process called alkylation. They are generally cytotoxic, mutagenic and carcinogenic.
