Design Rationale:

We have designed and synthesized these compounds on solid support based on substrate specificity information. As they are covalent inhibitors and contain an alkyne clickable tag, they would enable tracking of the active protease. We would like to get some more insight into their binding mode by crystallography as well as about their potency.
