What is e64?

E64 is a chemical compound that belongs to the class of cysteine protease inhibitors. It is used in biomedical research as a tool for studying the function and activity of protease enzymes, particularly those involved in the degradation of protein molecules.

E64 works by blocking the activity of cysteine protease enzymes, which are responsible for breaking down proteins within cells. This inhibition can be selective or non-selective, depending on the concentration and conditions of the experiment.

E64 has been shown to be effective in inhibiting the activity of a number of protease enzymes, including calpain, cathepsin, and papain. It has been used in a variety of research contexts, including studies on muscle biology, cancer cell death, and the regulation of protein turnover.

Although e64 has been extensively studied and characterized, it is important to note that its use in biomedical research should be carefully controlled and monitored, as excessive inhibition of protease activity can have negative effects on cell viability and function.
