                                    We have explored a series of spirocyclic piperidine amide derivatives ( 5) as tryptase inhibitors. Thus, 4 (JNJ-27390467) was identified as a potent, selective tryptase inhibitor with oral efficacy in two animal models of airway inflammation ( sheep and guinea pig asthma models). An X-ray co-crystal structure of 4 tryptase revealed a hydrophobic pocket in the enzyme's active site, which is induced by the phenylethynyl group and is comprised of amino acid residues from two different monomers of the tetrameric protein.
