NSC228155 is primarily used in biochemical and pharmacological research as a small-molecule inhibitor targeting specific cellular pathways. It has shown activity in studies involving cancer cell proliferation, where it interferes with protein-protein interactions critical for tumor growth. This compound is often employed in high-throughput screening assays to identify potential anticancer agents due to its ability to modulate signaling pathways involved in cell cycle regulation and apoptosis. Its role as a probe compound makes it valuable for understanding molecular mechanisms in disease models, particularly in oncology research. Additionally, NSC228155 serves as a lead structure for the development of more potent and selective inhibitors in drug discovery programs.
