Pepstatin A(Cat No.:I002902)is a potent and specific inhibitor of aspartic proteases, such as pepsin, renin, and cathepsin D. It is a naturally occurring pentapeptide isolated from Streptomyces species and widely used in biochemical research to study protease activity and inhibition. By binding tightly to the active site of aspartic proteases, Pepstatin A prevents substrate cleavage, making it an essential tool in protease mechanism studies and drug discovery. Its role in investigating protease-related diseases, including cancer and neurodegenerative disorders, highlights its importance in pharmaceutical and enzymology research.
