thermolysin

Thermolysin is an extracellular metalloendopeptidase from Bacillus thermolysinophilus that selectively catalyzes short peptides.

Phosphoramidon is a membrane metallo-endopeptidase & endothelin-converting enzyme inhibitor and thermolysin inhibitor, which is obtained from culture filtrate of Streptomyces tanashiensis.

Laccaridione B inhibits the activity of serine proteases. It exhibits inhibitory effects on trypsin, papain, thermolysin, collagenase, and zinc metalloprotease with IC50 values of 10.9 μg/mL, 5.1 μg/mL, 8.4 μg/mL, 5.7 μg/mL, and 3.0 μg/mL, respectively. Additionally, Laccaridione B shows significant antiproliferative activity against L-929, K-562, and HeLa cells, with IC50 values of 2.4 μg/mL, 1.8 μg/mL, and 13.9 μg/mL, respectively.

Aureoquinone is a broad-spectrum proteinase (protease) inhibitor. It inhibits trypsin, papain, thermolysin, collagenase, and pronase, with IC50 values of 11.4 μg mL, 14.5 μg mL, 17.8 μg mL, 7.1 μg mL, and 8.7 μg mL, respectively.

Laccaridione A can inhibit the activity of anti-serine proteases. The IC50 values of Laccaridione A for inhibiting trypsin, papain, thermolysin, collagenase, and zinc proteases are 14.7 μg/mL, 2.5 μg/mL, 18.8 μg/mL, 7.2 μg/mL, and 18.2 μg/mL, respectively.
