CZC-54252 is primarily used as a selective inhibitor in biochemical research, particularly targeting specific kinase pathways involved in cellular signaling. It has been applied in studies related to inflammation and immune response modulation due to its ability to suppress overactive signaling in immune cells. Researchers utilize CZC-54252 to probe the role of its target kinase in disease models, especially in autoimmune conditions and certain cancers where pathway dysregulation occurs. Its high selectivity makes it a valuable tool for validating therapeutic targets without significant off-target effects in preclinical experiments.
