| Chemotherapy is a treatment approach that uses drugs to target and kill rapidly dividing cells, primarily cancer cells. However, because many normal cells also divide quickly (such as those in the bone marrow, digestive tract, and hair follicles), chemotherapy can also affect these cells, leading to a range of side effects. Main Classes of Chemotherapy Agents and Examples Alkylating Agents: -work by adding alkyl groups to DNA, which interferes with the DNA’s structure and prevents replication. Examples: Cyclophosphamide, Ifosfamide, Melphalan, Chlorambucil, Busulfan. Anti-metabolites: -interfere with DNA and RNA synthesis by substituting for the normal building blocks of nucleic acids. Examples: Methotrexate, 5-Fluorouracil (5-FU), Cytarabine, Gemcitabine, 6-Mercaptopurine. Anti-microtubule Agents: -interfere with the structures that separate chromosomes during cell division (mitosis). Examples: Paclitaxel, Docetaxel, Vincristine, Vinblastine. Topoisomerase Inhibitors: -target the enzymes topoisomerase I and II, which control the changes in DNA structure required for replication. Examples: Etoposide (topoisomerase II inhibitor), Irinotecan (topoisomerase I inhibitor), Topotecan. Cytotoxic Antibiotics: -intercalate into DNA, inhibiting the replication of cancer cells. Examples: Doxorubicin, Daunorubicin, Bleomycin, Mitoxantrone. Platinum-Based Agents: -contain platinum and cause cross-linking of DNA, which interferes with DNA repair and replication. Examples: Cisplatin, Carboplatin, Oxaliplatin. Many chemotherapy agents exert their effects, at least in part, by inducing oxidative stress in cancer cells. They can increase ROS levels through several mechanisms: -Direct generation of free radicals. -Disruption of mitochondrial function, leading to increased production of ROS. -Interference with the cell’s antioxidant systems. -May want to avoid antioxidants 7 days bef ore and 7 days after chemo. Examples: NAC, Glutathione, Alpha Lipoic Acid, Vitamin E -anti-oxidants known to have pro-oxidant effects (like Quercetin, Curcumin, etc.) should not be taken 2-3 days before and after chemo -pro-oxidants known to bring good benefit to chemo can be continued during chemo. Examples are: Omega 3, Aremisia Annua, Silver NanoParticles. |

| Enzymes involved in regulating gene expression by removing acetyl groups from histones, the proteins around which DNA is wrapped. -Many cancers exhibit altered expression levels of HDACs, which can contribute to the dysregulation of genes involved in cell growth, survival, and differentiation. -HDACs can repress the expression of tumor suppressor genes, leading to uncontrolled cell proliferation and survival. This repression can be a key factor in the development and progression of cancer. -HDAC inhibitors (HDACi) have been developed and are being investigated for their ability to reactivate silenced genes, induce cell cycle arrest, and promote apoptosis in cancer cells. -HDAC1, HDAC2): Often overexpressed in various cancers, including breast, prostate, and colorectal cancers. Their overexpression is associated with poor prognosis. -HDAC4, HDAC5): These may have both oncogenic and tumor-suppressive roles depending on the context and cancer type. -While HDACs are not classified as traditional oncogenes, their overexpression and activity can contribute to oncogenic processes. -HDAC inhibitor works by preventing the removal of acetyl groups from histones, thereby modulating gene expression, influencing cell behavior, and potentially reversing aberrant gene silencing seen in various diseases. -HDAC inhibitors can help reactivate these genes, thereby inhibiting growth and inducing apoptosis in cancer cells. |
