Various types of cancer drugs, including Methotrexate, target and eliminate cancer cells in different ways. Understanding how these drugs work can provide insight into their effectiveness and potential side effects.

Antimetabolites: Interfering with DNA synthesis

Methotrexate belongs to the group of drugs known as antimetabolites. These drugs work by inhibiting the activity of enzymes necessary for DNA synthesis. By disrupting this essential process, Methotrexate prevents cancer cells from reproducing and growing.

Antimetabolites, including Methotrexate, mimic and interfere with the building blocks of DNA. For example, Methotrexate acts as a folate analogue, blocking the enzyme dihydrofolate reductase (DHFR) that is crucial for the synthesis of DNA and RNA. By inhibiting DHFR, Methotrexate disrupts the production of nucleotides, the building blocks of DNA.

This interference with DNA synthesis deprives cancer cells of the ability to replicate and leads to their eventual death. As cancer cells rely heavily on rapid DNA replication for their growth and survival, targeting this process can be an effective strategy to eliminate these cells.

Chemotherapy drugs: Attacking rapidly dividing cells

Chemotherapy drugs, another type of cancer treatment, work by attacking rapidly dividing cells, including cancer cells. Unlike antimetabolites, chemotherapy drugs target not only cancer cells but also normal healthy cells that divide quickly, such as those in the bone marrow, hair follicles, and digestive tract.

These drugs disrupt the cell cycle, preventing cancer cells from dividing and multiplying rapidly. While chemotherapy can be effective in killing cancer cells, it can also cause significant side effects due to its impact on normal cells.

Targeted therapies: Focusing on specific molecules or pathways

Targeted therapies, a relatively newer approach in cancer treatment, aim to specifically target certain molecules or pathways that are essential for cancer cell survival and growth. Unlike chemotherapy, targeted therapies are designed to have minimal impact on normal cells, resulting in fewer side effects.

For example, some cancer cells have specific genetic mutations or overactive signaling pathways that contribute to their growth. Targeted therapies can be designed to selectively inhibit these mutations or pathways, effectively disabling the cancer cells’ ability to survive and proliferate.

Immunotherapy: Harnessing the immune system

Immunotherapy drugs work by harnessing the body’s immune system to recognize and destroy cancer cells. These drugs activate the immune system, enabling it to recognize cancer cells as foreign and mount an attack against them. Immunotherapy has shown great promise in treating various types of cancer and has led to significant advancements in cancer treatment.

By targeting specific molecules on cancer cells or enhancing immune responses, immunotherapy drugs can help overcome the ability of cancer cells to evade the immune system, leading to their elimination.
