Alkylating agents these drugs work in all phases of the cell cycle and are used to treat many different cancers, including cancers of the lung, breast, and ovary as well as leukemia, lymphoma, hodgkin disease, multiple myeloma, and sarcoma,. Alkylating agents are the broad spectrum agennts chemistry different reactive moiety: bis (chloroethyl) amine / ethyleneimine / nitrosourea, responsible for different actions either two or more of these are present known as bi- / poly-functional mechanism of action. Alkylating agent listen (al-kuh-lay-ting ay-jent) a type of drug that is used in the treatment of cancer it interferes with the cell's dna and inhibits cancer cell growth.
A second mechanism by which alkylating agents cause dna damage is the formation of cross-bridges, bonds between atoms in the dna in this process, two bases are linked together by an alkylating agent that has two dna binding sites. Chemotherapy agents that can cause reversible cardiotoxicity are trastuzumab, bevacizumab, lapatinib, and sunitinib these agents also may cause hypertension a decrease in vascular endothelial growth factor (vegf) results in a reduction of nitric oxide (no) in the arteriolar wall. Overview of antineoplastic agents by lisa g barber, dvm, assistant professor, not as a target for chemotherapeutic agents, but as a time during which dormant tumor cells can escape or repair the effects of drug therapy alkylating agents, antimetabolites, mitotic inhibitors, antineoplastic antibiotics, hormonal agents, and.
This is a brief overview of chemotherapeutic agents, their mechanism of action, and some related side effects i created this presentation with google slides. Chemotherapeutic agents: dna-interactive alkylating agents and antitumour platinum-based drugs zahid h siddik the university of texas m d anderson cancer center, houston, tx, usa introduction the long-term understanding of cancer growth is that it is. These chemotherapy medicines are classified as alkylating agents alkylating agents are medicines that directly damage the dna inside cancer cells this prevents the cancer cells from multiplying these chemotherapy medicines are used to treat cancer for example, bendamustine, busulfan. Antineoplastic [an″te-, an″ti-ne″o-plas´tik] inhibiting the maturation and proliferation of malignant cells antineoplastic agent antineoplastic therapy a regimen that includes chemotherapy, aimed at destruction of malignant cells using a variety of agents that directly affect cellular growth and development chemotherapy is but one of a variety.
The alkylating agents were the first nonhormonal drugs to be used effectively in the treatment of cancer, and the story behind the recognition of the antitumor effects of these compounds is a remarkable one. Alkylating agents were among the first anti-cancer drugs and are the most commonly used agents in chemotherapy today alkylating agents act directly on dna, causing cross-linking of dna strands, abnormal base pairing, or dna strand breaks, thus preventing the cell from dividing. Thiotepa is another alkylating agent how it works: alkylating agents weaken or destroy breast cancer cells by damaging the cells’ genetic material uses: cytoxan usually is given in combination with other chemotherapy medicines. Alkylating agents are a class of chemotherapy drugs that bind to dna and prevent proper dna replication these have chemical groups that can form permanent covalent bonds with nucleoplhillic substances in the dna the five major categories of alkylating agents are - nitrogen mustards - nitrosoureas - alkyl sulfonates - triazines - ethylenimines alkylating agents attach an alkyl group to the. Abstract cytostatic antibiotics of the anthracycline class are the best known of the chemotherapeutic agents that cause cardiotoxicity alkylating agents such as cyclophosphamide, ifosfamide, cisplatin, carmustine, busulfan, chlormethine and mitomycin have also been associated with cardiotoxicity.
Alkylation agents as chemotherapeutic agents
Carboplatin is an anticancer chemotherapy drug that is classified as an alkylating agent it is used to treat several types of cancer, including lung, head and neck, endometrial, esophageal, bladder, breast, and cervical. The alkylating agent dose (aad) and the cyclophosphamide equivalent dose (ced) risk-stratification systems allow calculation of risk using the aad, a score of 1, 2 or 3 is given for the cumulative dose of alkylating agent that falls within the first, second or third tertile, respectively. The importance and limitations of the alkylating agents as chemotherapeutic drugs and as tools for examining the basic mechanisms involved in carcinogenesis and mutation have been considered in the light of recent findings. Important take home points • bifunctional vs monofunctional alkylating agents • pharmacologic mechanism of action of alkylators on dna • side effects of alkylating and platinum agents • chemotherapy induced nausea mechanisms • effects of antineoplastic drugs on gonad function.
- Chemotherapeutic agents, also referred to as antineoplastic agents, are used to directly or indirectly inhibit the proliferation of rapidly growing cells, typically in the context of malignancy they are classified according to their mechanism of action and include alkylating agents, antimetabolites, topoisomerase inhibitors, and mitotic inhibitors.
- Alkylating agents exert profound cytotoxic effects on actively growing cells and this is the basic rationale for the use of these agents in cancer chemotherapy (1,2) the biological effects of alkylating agents are attributed to the formation of alkylated bases in cellular dna.
- Drug class: immunosuppressant, alkylating agent, cancer chemotherapeutic mechanism of action: an alkylating agent that is one of the most efficacious immunosuppressive drugs available (destroys proliferating lymphoid cells can be given orally (most alkylating agents are given iv), and it is well absorbed.

Undoubtedly, the toxicity of the chemotherapeutic agent used importantly determines both the development and type of kidney injury sustained ifosfamide is an alkylating agent used for certain cancers, including sarcomas, testicular cancer, and some forms of lymphoma ifosfamide’s major adverse effect is kidney injury. Alkylating agents can cause long-term damage to the bone marrow in rare cases, people with cancer who are treated with these medicines can get leukemia years later but carboplatin, cisplatin, and oxaliplatin (also called the platinum drugs) are less likely than the other alkylating agents to cause leukemia.
