Abstract

A solid phase combinatorial library was designed based on X-ray structures and in-silico models to explore an inducible S4+ pocket, which is formed by a simple side-chain rotation of Tyr95. This inducible S4+ pocket is unique to β-tryptase and does not exist for Other trypsin-like serine proteases of interest. Therefore, inhibitors utilizing this pocket have inherent advantages for being selective against Other proteases in the same family. A member of this library was found to be a potent and selective β-tryptase inhibitor with a suitable pharmacokinetic profile for further clinical evaluation.
