SOS1 inhibitor 1 is primarily used in cancer research and therapy development. It targets the SOS1 protein, which plays a critical role in the activation of the RAS signaling pathway. This pathway is often dysregulated in various cancers, leading to uncontrolled cell growth and proliferation. By inhibiting SOS1, this compound helps to block the activation of RAS proteins, thereby suppressing tumor growth and progression. It is particularly studied in the context of cancers with RAS mutations, such as pancreatic, lung, and colorectal cancers. Additionally, it serves as a valuable tool in biochemical research to better understand the mechanisms of RAS signaling and identify potential therapeutic strategies.
