Are alkylating drugs chemotherapy?
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.
What drugs are alkylating agents?
Alkylating agents were one of the first classes of drugs to be used against cancer. There are five traditional categories of alkylating agents: Nitrogen mustards (eg, bendamustine, chlorambucil, cyclophosphamide, ifosfamide, mechlorethamine, melphalan) Nitrosoureas (eg, carmustine, lomustine, streptozocin)
What are alkylating agents as anti cancer drugs?
Alkylating agents (al-ka-LAYT-ing AY-jints) are a family of anticancer drugs that interfere with cell’s DNA and inhibit cancer cell growth. They are so named because of their ability to add alkyl groups to negatively charged groups on biological molecules such as DNA and proteins.

Which are alkylating agents?
Some examples of alkylating agents are nitrogen mustards (chlorambucil and cyclophosphamide), cisplatin, nitrosoureas (carmustine, lomustine, and semustine), alkylsulfonates (busulfan), ethyleneimines (thiotepa), and triazines (dacarbazine).
What do you mean by alkylating agent?
: a substance that causes replacement of hydrogen by an alkyl group especially in a biologically important molecule specifically : one with mutagenic activity that inhibits cell division and growth and is used to treat some cancers.

How do alkylating agents cause cancer?
Alkylating agents induce dose-limiting myelosuppression and cause sublethal DNA damage to hematopoietic progenitors, causing mutational events that lead to malignant transformation to preleukemic and leukemic states.
What do chemotherapy agents do?
Chemotherapy drugs help destroy, shrink, or control those cells. It might also treat symptoms the cancer causes, like pain. You might also get chemo to shrink a tumor before your doctor removes it in surgery.

Medications Used in Chemotherapy. The main chemotherapy drugs used in breast cancer treatment are doxorubicin and docetaxel, but there are many other available drugs. They include 5-fluorouracil, cyclophosphamide, epirubicin, gemcitabine, idiomycin, methotrexate and vinorelbine.
What are the advantages of chemotherapy?
The worst disadvantage of chemotherapy is the unpleasant side effects such as nausea, hair loss and extreme discomfort. A second disadvantage is that chemicals must be carefully selected depending on the type and stage of the cancer.
