caspase-4 Inhibitors

Z-WEHD-FMK is a selective inhibitor of caspase-4, characterized by its ability to form covalent bonds with the active site cysteine residue. This irreversible binding alters the enzyme's structural dynamics, effectively blocking substrate access. The compound's unique hydrophobic and polar regions facilitate specific interactions with the enzyme's active site, influencing reaction kinetics and potentially modulating downstream signaling cascades. Its distinct mechanism highlights the complexity of caspase regulation in cellular processes.

Caspase-1 inhibitor exhibits a unique mechanism of action by targeting the active site of caspase-4, leading to a conformational change that disrupts enzymatic activity. This compound engages in specific hydrogen bonding and hydrophobic interactions, enhancing its selectivity. The inhibitor's kinetic profile reveals a slow-onset inhibition, allowing for nuanced modulation of caspase-4 activity. Its distinct structural features contribute to the intricate balance of apoptotic and inflammatory pathways within cells.

Caspase inhibitor II selectively binds to caspase-4, stabilizing an inactive conformation that prevents substrate access. This compound showcases unique electrostatic interactions that enhance its affinity for the enzyme, resulting in a pronounced reduction in catalytic efficiency. Its reaction kinetics indicate a competitive inhibition pattern, allowing for precise control over caspase-4-mediated processes. The inhibitor's structural characteristics facilitate targeted modulation of cellular signaling pathways, influencing apoptotic responses.

BD-FMK is a potent inhibitor of Caspase-4. It functions as an irreversible inhibitor by covalently binding to the active site of the caspase, thereby preventing its catalytic activity. This helps protect cells from caspase-mediated apoptosis.
