K-Ras-IN-1 is primarily used in cancer research, particularly in studying the role of the K-Ras protein in tumor growth and development. It serves as a potent inhibitor of K-Ras, a protein often mutated in various cancers, including pancreatic, lung, and colorectal cancers. Researchers utilize this compound to investigate signaling pathways involved in cancer progression and to evaluate potential therapeutic strategies targeting K-Ras mutations. Its application extends to preclinical studies, where it helps in understanding the mechanisms of drug resistance and identifying novel approaches to inhibit oncogenic K-Ras activity. Additionally, K-Ras-IN-1 is employed in screening assays to discover and develop new anticancer drugs that specifically target K-Ras-driven cancers.
