(E/Z)-BCI is primarily used in research settings to study and manipulate cellular signaling pathways, particularly those involving protein-protein interactions. It is often employed as a tool compound to investigate the role of specific proteins in biological processes, such as cell proliferation, differentiation, and apoptosis. Researchers utilize it to selectively degrade or inhibit target proteins, enabling a deeper understanding of their functions in disease mechanisms. This makes it valuable in drug discovery and development, where it helps identify potential therapeutic targets. Additionally, (E/Z)-BCI is used in chemical biology to explore the dynamics of cellular networks and validate the efficacy of novel pharmacological agents. Its application extends to studying cancer biology, neurodegenerative diseases, and other conditions where dysregulated signaling pathways play a critical role.
