block proteins involved in cell growth signaling pathways

RAF inhibitors, also known as RAF kinase inhibitors, are a class of drugs designed to block the activity of RAF kinases, which are proteins involved in cell signaling pathways that control cell growth and division. These inhibitors are particularly important in the treatment of certain cancers, such as melanoma, where mutations in the RAF gene (e.g., BRAF mutations) lead to uncontrolled cell proliferation. By inhibiting RAF kinases, these drugs can help to slow down or stop the growth of cancer cells.
