Cysteine Protease

Cysteine Protease

Cysteine Protease inhibitors are compounds that target and inhibit cysteine proteases, a class of enzymes that break down proteins by cleaving peptide bonds in which a cysteine residue acts as the nucleophile. These enzymes are involved in various physiological processes, including apoptosis, immune response, and protein turnover. Cysteine protease inhibitors are crucial for studying diseases such as cancer, neurodegenerative disorders, and parasitic infections. At CymitQuimica, we provide cysteine protease inhibitors to aid your research in proteolysis, cellular regulation, and drug discovery.
