Hepsin, a type II transmembrane serine protease, is an attractive protein as a potential therapeutic and diagnostic biomarker for prostate cancer because it is highly up-regulated in prostate cancer and promotes both progression and metastasis. Starting from the reported tetrapeptide hepsin inhibitor Ac-KQLR-ketothiazole (kt) (1), we investigated the minimal structural requirements for hepsin inhibitory activity by truncating amino acids at the N-terminus. The kt and ketobenzothiazole (kbt) dipeptide analogs Ac-LR-kt (3) and Ac-LR-kbt (15) were found to be potent hepsin inhibitors, exhibiting Ki values of 22 nM and 3 nM, respectively. The present work suggests that LR-containing dipeptide molecules could be useful as lead compounds for the development of novel hepsin inhibitors.

We studied the factors affecting the selectivity of peptidomimetic inhibitors of the highly homologous proteases matriptase and matriptase-2 across subpockets using docking simulations. We observed that the farther away a subpocket is located from the catalytic site, the more pronounced its role in selectivity. As a result of our exhaustive virtual screening, we biochemically validated novel potent and selective inhibitors of both enzymes.
