Used in research settings as a selective inhibitor of the anaplastic lymphoma kinase (ALK), particularly in studies involving ALK-positive cancer cell lines. It demonstrates potent activity in blocking ALK-mediated signaling pathways, making it a tool compound for evaluating tumor growth inhibition in models of non-small cell lung cancer and other ALK-driven cancers. Its application is primarily confined to preclinical studies to assess pharmacokinetics, efficacy, and mechanism of action in targeted cancer therapy development.
