CAS 219138-02-0: L-a-Asparagine,N-[(phenylmethoxy)carbonyl]-L-isoleucyl-L-a-glutamyl-L-threonyl-N-[2-oxo-4-(trifluoromethyl)-2H-1-benzopyran-7-yl]-(9CI)

Caspase substrates are a class of pharmacological agents that regulate apoptosis. Caspases are proteases that cleave specific proteins in the cell, leading to apoptosis. Pro-apoptotic proteins activate caspases, while anti-apoptotic proteins inhibit them. Caspase substrates can be either pro-caspase or anti-caspase, depending on the desired effect. They may also be used to regulate caspases without affecting their activity. The caspase substrate is cleaved by caspases and releases a polypeptide fragment that triggers apoptosis in some cells, but not others. For example, the Hl-60 cell line is resistant to the pro-apoptotic effects of the substrate because it contains an anti-apoptotic protein called Bcl-2. In contrast, myocardial cells contain pro-apoptotic proteins and are sensitive to the pro-apoptotic effects of the substrate. In

Z-IETD-AFC is a fluorescent substrate for caspase-8 and granzyme B. It can be used to quantify cysteinyl aspartate-8 or granzyme B activity.
