What are are the advantages of using FMK based caspase inhibitors and how do they differ from CHO-based inhibitors?
The FMK-based caspase inhibitors covalently modify the thiol group of the enzyme making them irreversible inhibitors. Generally, at the amine end of the inhibitor we have a benzyloxycarbonyl (Z), biotin, or aceytl (Ac) group. These groups also increase hydrophobicity of the molecule, which makes them more cell-permeable. Compared to the inhibitors with an Ac or a biotin group, those inhibitors with a Z-group are even more cell-permeable. Inhibitors with a biotin group can serve as a detection tool and are useful in tagging the enzyme-inhibitor site.
