MMP inhibitor I is a peptide inhibitor of matrix metalloproteinase-1 (MMP-1), MMP-2, and MMP-3 (IC50s = 1.3, 30, and 150 μM, respectively). It is selective for MMP-1, MMP-2, and MMP-3 over the proteases thermolysin, urease, trypsin, α-chymotrypsin, plasmin, and elastase at concentrations up to 4 mM.
CRA-2059 hydrochloride is a highly specific and selective tryptase inhibitor, with a Ki of 620 pM for recombinant human tryptase-β (rHTβ)[1][2].
Tryptase is a trypsin-like serine protease found as a major protein component in human mast cell secretory granules. CRA-2059 hydrochloride has the potential for inflammatory bowel disease research[1].

Suomilide effectively inhibits human trypsin-2 and trypsin-3, displaying IC50 values of 4.7 nM and 11.5 nM, respectively. Additionally, it exhibits inhibition of trypsin-1 with an IC50 value of 104 nM.
Calmodulin antagonist-1 (W-7) is a calmodulin (CaM) antagonist that effectively inhibits calmodulin-activated Ca 2+ -phosphodiesterase (PDE) with an IC 50 of 28 μM. This compound also competitively inhibits trypsin-treated Ca 2+ -PDE with respect to cyclic GMP, exhibiting an IC 50 of 375 μM and a K i value of 300 μM.
