CPA1 Activators

CPA1 Activators are compounds that, through various mechanisms, ensure the enhancement of CPA1's proteolytic activity. Chymostatin and gabexate mesilate are protease inhibitors that prevent the action of chymotrypsin-like enzymes and various serine proteases, respectively, leading to an environment where CPA1 can act on substrates with reduced competition. Similarly, camostat mesilate and nafamostat mesilate inhibit trypsin and other serine proteases, which could result in a higher availability of peptide substrates for CPA1, allowing for increased activation and function of this protease.

Benzamidine, aprotinin, and sivelestat function as inhibitors of specificserine proteases, while E-64 targets cysteine proteases. These inhibitors contribute to a proteolytic environment where CPA1's substrates are less likely to be degraded by competing proteases, indirectly enhancing CPA1's functional activity. AEBSF, by covalently modifying the active sites of serine proteases, ensures that CPA1 has more substrates to act upon, as it faces less proteolytic competition. Phosphoramidon and leupeptin, by inhibiting metalloproteases and a range of serine and cysteine proteases, respectively, create a biochemical context in which CPA1 can operate more effectively due to the increased presence of intact peptide substrates. Lastly, pepstatin A, by targeting aspartic proteases, contributes to the preservation of CPA1's peptide substrates, facilitating an enhanced activity of CPA1.
