Tumor resistance to alkylating agents conferred by mechanisms operative only in vivo. BA Teicher,; TS Herman,; SA Holden,; YY Wang,; MR Pfeffer, 

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.

This was the first classification of an anti-cancer drug to be developed. Chemotherapy precautions must be taken Administration considerations Chemo certified nurses Administration considerations Chemo … al·kyl·at·ing a·gent a drug or chemical that, through the formation of covalent bonds, forms a derivatized tissue constituent permanently containing part of the drug or chemical compound; frequently carcinogenic and mutagenic, but often used in the chemotherapy of cancer (for example, nitrogen mustards and carmustine). In some cases, a cell can fix DNA damage simply by reversing the chemical reaction that caused it. To understand this, we need to realize that "DNA damage" o alkylating agent R OR' O R'Z OH alkylating agent R'Z OR' OH alkylating agent R'Z OR' Carboxylic Acids Phenols Acidic Enols alkylating agent R'Z Thiols RSH RSR' Scheme 1.

Classic alkylating agents interfere with DNA replication by crosslinking DNA strands, DNA strand breaking, and abnormal pairing of base pairs. They exert their lethal effects on cells throughout the cell cycle but tend to be more effective against rapidly dividing cells.1, 7, 11 Because alkylating agents are active against cells in G0, they can be used to debulk tumours, Learn quiz pharmacology alkylating agents with free interactive flashcards.

Alkylating agents (ATC code L01A) are highly reactive compounds that easily attach to DNA and cellular proteins. The primary mode of action for most alkylating drugs is via cross-linking of DNA strands.

Alkylating agents are indicated for the following medical conditions: Treatment of slow-growing cancers, like lymphomas, leukemias, myelomas, some ovarian, testicular, and breast cancers, and pancreatic cancers.

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. Many of these comprise drugs that currently form part of the combinations used to treat neoplastic disease. This account however includes only a limited number of alkylating agents.

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.
