Raf inhibitors

Raf inhibitors are a class of pharmaceutical compounds that target the Raf protein kinase family, specifically Raf-1 and B-Raf. These proteins are key components of the Ras/Raf/MEK/ERK signaling pathway, which regulates cell growth, differentiation, and survival. By inhibiting Raf kinases, these inhibitors disrupt downstream signaling cascades involved in cellular proliferation and oncogenesis. B-Raf inhibitors like vemurafenib and dabrafenib are particularly notable in cancer therapy, especially in treating melanomas harboring the BRAF V600E mutation, which constitutively activates the MAPK pathway.
