CPTH2 is primarily utilized in research settings, particularly in the study of cancer biology. It functions as an inhibitor of the p53-MDM2 interaction, which is crucial in regulating cell cycle and apoptosis. By blocking this interaction, CPTH2 can potentially reactivate p53 in cancer cells, leading to their death. This makes it a valuable tool for investigating new therapeutic strategies for cancers where p53 is inactivated. Additionally, CPTH2 is used in biochemical assays to understand the mechanisms of protein-protein interactions and to screen for compounds that can modulate these interactions. Its application extends to the development of novel anticancer drugs, offering insights into targeting specific pathways involved in tumor suppression.
