FIPI is primarily used in research settings to study the role of specific enzymes in cellular processes. It is particularly valuable in investigating the function of phospholipase D (PLD), an enzyme involved in signal transduction and lipid metabolism. By inhibiting PLD, FIPI helps researchers understand its role in various biological pathways, including cell growth, differentiation, and membrane trafficking. This makes it a useful tool in exploring potential therapeutic targets for diseases like cancer, where PLD activity is often dysregulated. Additionally, FIPI is employed in studies related to inflammation and immune responses, as PLD is implicated in these processes. Its application contributes to advancements in biochemistry and pharmacology, aiding in the development of novel treatments.
