Abstract

The synthesis and evaluation as tryptase inhibitors of a library of 2,5-diketopiperazine derivatives containing guanidine or amidine functional groups is reported. Among the compounds evaluated, derivatives 6{CG4-CG8} and 6{CG4-CG9} are the most active compounds and have marked selectivity towards tryptase in front of trypsin.
