==Overview==
==Bovine trypsin bound by 4-piperidinebutyrate to make acylenzyme complex==
Improved peptide-based inhibitors of human beta tryptase were discovered, using information gleaned from tripeptide library screening and, structure-guided design methods, including fragment screening. Our efforts, sought to improve this class of inhibitors by replacing the traditional, Lys or Arg P1 element. The optimized compounds display low nanomolar, potency against the mast cell target and several hundred-fold selectivity, with respect to serine protease off targets. Thus, replacement of Lys/Arg, at P1 in a peptide-like scaffold does not need to be accompanied by a loss, in target affinity.
