Pepstatin Ammonium is a specific inhibitor of aspartic proteaseproduced by actinomycetes(hemoglobin-pepsin, hemoglobin-proctase, casein-pepsin, casein-proctase, casein-acidprotease and hemoglobin-acidprotease with IC50s of 4.5 nM, 6.2 nM, 150 nM, 290 nM
LRGILS-NH2 is a reversed amino acid sequence control peptide for SLIGRL-NH2, a protease-activated receptor-2 (PAR2) agonist that facilitates gastrointestinal transit in vivo.
Geranylgeranoic acid (GGA) is an isoprenoid that has been found inS. chinensisand has anticancer activity.1It induces apoptosis in Huh7 and PLC/PRF/5 human hepatoma cells and MLE-10 transformed mouse hepatocytes, but not primary mouse hepatocytes, when used at concentrations ranging from 1 to 20 μM. GGA (10 μM) induces apoptosis in Huh7 cellsvialoss of the mitochondrial membrane potential and activation of interleukin-1β-converting enzyme (ICE) and cysteine protease precursor 32 (CPP32).2It also inhibits lysine-specific demethylase 1 (LSD1; IC50= 46.97 μM).3 1.Shidoji, Y., and Ogawa, H.Natural occurrence of cancer-preventive geranylgeranoic acid in medicinal herbsJ.

Enteropeptidase fluorogenic substrate is a substrate for enteropeptidase that contains a 7-amino-4-trifluoromethylcoumarin (AFC) moiety. Enteropeptidase is a serine protease expressed in the proximal small intestine of higher animals that converts inactive trypsinogen to active trypsin by endoproteolytic cleavage. Enteropeptidase recognizes the highly specific amino acid sequence DDDDK on the fluorogenic substrate and cleaves after the lysine residue, releasing the AFC moiety. Enteropeptidase activity is quantified by fluorescent detection of AFC, which displays excitation emission spectra of 380 500 nm.

5-Hydroxytoluene-2,4-disulphonic acid diammonium is an impurity of Policresulen. Policresulen is a potent NS2B NS3 protease inhibitor with an IC50 of 0.48 μg mL. Policresulen effectively inhibits the replication of DENV2 virus in BHK-21 cells with an IC50 of 4.99 μg mL. Policresulen acted as a competitive inhibitor of the protease, and slightly affected the protease stability[1]. [1]. Deng-wei Wu, et al. Policresulen, a novel NS2B NS3 protease inhibitor, effectively inhibits the replication of DENV2 virus in BHK-21 cells. Acta Pharmacol Sin. 2015 Sep;36(9):1126-36.
