How do alkylating agents affect cancer cells
WebDrug Resistance: Cancer cells can acquire a resistance to alkylating agents by at least 3 mechanisms including: increased ability to repair DNA lesions. decreased permeability to the alkylating drug. increased production of glutathione or increased glutathione S-transferase which catalyzes the conjugation of the drug to gluathione.

WebNov 1, 2004 · Although some classes of antineoplastic agents generate high levels of oxidative stress, others, including the taxanes, vinca alkaloids, antifolates, and nucleoside and nucleotide analogues, generate only low levels. Nevertheless, all drugs generate some free radicals as they induce apoptosis in cancer cells.
WebJul 8, 2024 · Alkylation damages the DNA of cells, which prevents them from dividing, and causes them to die. Since cancer cells, in general, divide faster and with less error-correcting than healthy cells, cancer cells are more sensitive to this damage. In this way, mechlorethamine slows or stops the growth of cancer cells in your body. WebJun 28, 2024 · Cells were treated with two-dimensional dose responses of PARP inhib-itors and DNA alkylating agents for 5 days. Excess over Bliss additivity was determined for each condition. To facilitate comparison of PARP inhibitors, cross-sections of response surfaces at the concentrations of alkylating agent eliciting peak synergism are overlaid.
WebJan 4, 2024 · Alkylating agents: These affect the DNA and kill the cells at different stages of the cell life cycle. Antimetabolites: These mimic proteins that the cells need to survive. WebBecause these drugs are active in all phases of the cell cycle, they may be effective in large tumors that have fewer active cells. Cell cycle phase-nonspecific drugs are usually given as a single injection. Examples include the following: Alkylating agents Antitumor antibiotics Nitrosoureas Hormone and steroid drugs
