stefin A2l1 Inhibitors
Stefin A2l1 inhibitors are a class of chemical compounds specifically designed to target and inhibit the activity of Stefin A2l1, a member of the cystatin family of cysteine protease inhibitors. Cystatins like Stefin A2l1 play a crucial role in regulating the activity of cysteine proteases, which are enzymes responsible for breaking down proteins in various cellular processes. These proteases, including cathepsins, are involved in functions such as apoptosis, immune response, and protein turnover. By inhibiting cysteine proteases, Stefin A2l1 helps maintain protease homeostasis, preventing excessive or uncontrolled proteolytic activity that could damage tissues and cellular structures. Inhibitors of Stefin A2l1 work by disrupting this regulatory function, potentially allowing proteases to act unchecked, which can lead to altered protein degradation dynamics.
The mechanism of action of Stefin A2l1 inhibitors generally involves binding to the active site or regulatory domains of the Stefin A2l1 protein. This binding prevents Stefin A2l1 from interacting with cysteine proteases, leaving these enzymes free to carry out proteolysis without inhibition. Some inhibitors may induce conformational changes in Stefin A2l1, reducing its affinity for proteases and impairing its ability to regulate them. By inhibiting Stefin A2l1, these compounds can impact a variety of cellular processes dependent on regulated protease activity, such as cell death, tissue remodeling, and immune responses. Research into Stefin A2l1 inhibitors provides valuable insights into the fine-tuned balance between protease activity and inhibition, highlighting the importance of this balance in maintaining cellular homeostasis. Understanding how Stefin A2l1 functions as a protease inhibitor also sheds light on the broader regulatory mechanisms involved in controlling protein degradation within cells.

E-64 | 66701-25-5 | sc-201276 sc-201276A sc-201276B | 5 mg 25 mg 250 mg | $281.00 $947.00 $1574.00 | 14 | |
E-64 is a potent, irreversible inhibitor of cysteine proteases, which binds covalently to the active site thiol of these enzymes. Stefin A2l1, being a cysteine protease inhibitor, would be inhibited by E-64 as it would prevent Stefin A2l1 from interacting with its target proteases by occupying their active sites. | ||||||

Leupeptin is a reversible inhibitor of serine and cysteine proteases. It inhibits the activity of these proteases by forming a stable complex with their active sites. This would inhibit Stefin A2l1 by preventing it from binding to its target cysteine proteases, thereby inhibiting its function. | ||||||
MDL-28170 | 88191-84-8 | sc-201301 sc-201301A sc-201301B sc-201301C | 10 mg 50 mg 100 mg 500 mg | $69.00 $241.00 $447.00 $2195.00 | 20 | |
MDL-28170 is a calpain inhibitor that can also inhibit cathepsin B, a cysteine protease. As Stefin A2l1 functions as a cysteine protease inhibitor, MDL-28170 would inhibit the activity of cysteine proteases that Stefin A2l1 might regulate, thereby indirectly inhibiting the function of Stefin A2l1. | ||||||
Odanacatib | 603139-19-1 | sc-364675 sc-364675A sc-364675B | 5 mg 25 mg 250 mg | $218.00 $993.00 $1982.00 | 2 | |
Odanacatib is a selective inhibitor of cathepsin K, which is another cysteine protease. The inhibition of cathepsin K would reduce the functional demand on Stefin A2l1, thus indirectly inhibiting the protein by reducing its engagement with this protease. | ||||||
K777 | 233277-99-1 | sc-507382 | 10 mg | $566.00 | ||
K11777 is an irreversible inhibitor of the cysteine protease cruzain and has been shown to inhibit other cysteine proteases as well. This broad inhibition of cysteine proteases would limit the functional role of Stefin A2l1, as its target proteases would be inactivated by K11777. | ||||||

Z-FA-FMK is a fluoromethyl ketone-based inhibitor that targets cysteine proteases and inhibits them by irreversibly binding to the active site cysteine. This would inhibit the proteases that Stefin A2l1 targets, reducing its functional role in the cell. | ||||||
CA-074 | 134448-10-5 | sc-202513 | 1 mg | $321.00 | ||
CA-074 is a selective inhibitor of cathepsin B, which is another target of cysteine protease inhibitors. By inhibiting cathepsin B, CA-074 would reduce the interaction between Stefin A2l1 and cathepsin B, thereby inhibiting Stefin A2l1. | ||||||

Nitroxoline is a chelating agent that can inhibit metalloproteases by chelating the metal ions necessary for their activity. While Stefin A2l1 is not a metalloprotease, the inhibition of metalloproteases in the same pathway could reduce the functional pressure on Stefin A2l1. | ||||||
