INCA-6 is primarily used in biochemical research as a selective inhibitor of the protein phosphatase 2A (PP2A). It is particularly valuable in studies aimed at understanding the role of PP2A in cellular processes such as signal transduction, cell cycle regulation, and apoptosis. By inhibiting PP2A, researchers can investigate its impact on various signaling pathways and its interaction with other proteins. This chemical is also utilized in cancer research to explore the potential of PP2A inhibition in disrupting tumor growth and survival. Additionally, INCA-6 helps in elucidating the mechanisms of neurodegenerative diseases where PP2A dysregulation is implicated. Its application extends to pharmacological studies for developing therapeutic strategies targeting PP2A-related disorders.
