Used in research to study cellular processes, particularly in understanding the role of polyamine biosynthesis in cell growth and proliferation. It acts as a potent inhibitor of deoxyhypusine synthase, an enzyme critical for the activation of eukaryotic translation initiation factor 5A (eIF5A). This makes it valuable in exploring its potential in cancer therapy, as inhibiting eIF5A activation can suppress tumor growth. Additionally, it is utilized in studies related to aging, viral replication, and neurodegenerative diseases, where eIF5A plays a significant role. Its application extends to investigating cellular stress responses and protein synthesis regulation.
