The synthesis of α-aminophosphonate analogues of tyrosine and tryptophan, e.g. 4 and 5 respectively, and their incorporation into proline-containing dipeptides is reported; of the sequences synthesised, the dipeptide Z-Pro-TrpP(OPh)2 is the only derivative that functions as an irreversible inactivator of the serine proteinase chymotrypsin, in contrast, the tyrosine analogue 4 behaves as a competitive reversible inhibitor of the enzyme and the tryptophan analogue 5 behaves as a slow-binding inhibitor.

in proteolysis and signaling. In prostate cancer (PCa), increased KLK activity promotes tumor growth and metastasis through multiple biochemical pathways, and specific quantification and tracking of changes in the KLK activome could contribute to validation of KLKs as potential drug targets. Herein we report a technology platform based on novel activity-based probes (ABPs) and inhibitors enabling simultaneous
