trypsin

Trypsin is a serine protease that can be isolated from fish to hydrolyze lysine or arginine carboxy-side proteins. With the anti-inflammatory activity, Trypsin could induce the cell membrane fusion of PDCoV-infected cells through the interaction between the S glycoprotein of PDCoV and pAPN, activate PAR2 and PAR4, and promote cell proliferation and differentiation. Trypsin can be used to promote wound healing and study neurogenic inflammation.

Trypsin Inhibitor, soybean is a trypsin inhibitor extracted from leguminous plants.

Chymotrypsin (Chymotrypsin A) is a serine protease synthesized by the pancreas, which cleaves protein chains on the carboxyl side of aromatic amino acids.

L-Serine (serine) is a non-essential amino acid in humans, L-Serine is present and functionally important in many proteins.L-Serine is also found at the active site of the serine protease enzyme class that includes trypsin and chymotrypsin.

Alpha-Amyrin (alpha-Amyrine) is an inhibitor of trypsin and chymotrypsin with antineoplastic effects. alpha-Amyrin can be used in studies about acting as a hepatomodulatory.

Demethylwedelolactone is a natural product isolated from Eclipta alba, has trypsin inhibitory effect an IC50 of 3.0 μM. it exerts anti-invasive growth effect on breast cancer cells.

23-O-β-D-Glucopyranosyl-20-isoveratramine, extracted from nettles, shows promise as an anti-allergic agent. Nettle extract contains a range of COX-1, COX-2, 5-lipoxygenase, and trypsin-like inhibitors, as well as H1 antagonists. These compounds collectively help mitigate symptoms of seasonal allergies, allergic rhinitis, and other inflammatory diseases, offering both treatment and preventive benefits [1].

1. Fraxinellone significantly reduced weight loss and diarrhea in mice and alleviated the macroscopic and microscopic signs of the disease. 2. Fraxinellone exhibited a variety of insecticidal activities including feeding-deterrent activity, inhibition of growth, and larvicidal activity. 3. Fraxinellone has effect in the midgut metabolism of Mythimna separata (M. separata), via protease (especially the weak alkaline trypsin-like enzyme), carboxylesterase and glutathione S-transferase.

Nostosin G, a linear peptide, comprises three subunits: 4-hydroxyphenyllactic acid (Hpla), homotyrosine (Hty), and argininal. It exhibits a potent trypsin inhibitory effect, demonstrated by an IC 50 value of 0.1 μM [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.

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.

Marizomib is a novel irreversible brain-permeable proteasome inhibitor that inhibits CT-L (β5), CT-T-laspase-like (C-L, β1), and trypsin-like (T-L, β2) 20S proteasomes with IC50s of 3.5, 28, and 430 nM.[3]
