INCA-6 is used in biological and pharmacological research, particularly in studying enzyme mechanisms and intracellular signaling pathways. It serves as a selective inhibitor of protein kinase CK2, which plays a crucial role in regulating various cellular processes such as cell division, apoptosis, and stress responses. By inhibiting CK2, INCA-6 enables researchers to explore its functions in diseases like cancer and aids in the development of targeted therapies with greater specificity.
