CCT241533 is primarily used in research settings as a potent and selective inhibitor of the protein kinase ALK (Anaplastic Lymphoma Kinase). It is particularly valuable in studying the role of ALK in various cancers, such as non-small cell lung cancer (NSCLC) and neuroblastoma. Researchers utilize this compound to investigate ALK signaling pathways and its impact on tumor growth and survival. Additionally, CCT241533 helps in evaluating the efficacy of ALK inhibition as a therapeutic strategy, contributing to the development of targeted cancer treatments. Its selectivity also makes it a useful tool for understanding ALK's biological functions in cellular and molecular studies.
