cathepsin

Cathepsin D and E FRET Substrate acetate is a fluorogenic substrate for cathepsins D and E but not for B, H, or L. Cathepsin D and E FRET Substrate acetate can be used in mechanistic studies on cathepsins D and E studies.

Z-FA-FMK can irreversibly inhibit cysteine protease and also inhibit effector caspases.

Mca-GKPILFFRL-Dpa-r-amide, FRET substrate for cathepsin D and E. Also cleaved by napsin A.

Cathepsin D and E FRET Substrate acetate is a fluorogenic substrate selectively cleaved by cathepsins D and E at the Phe-Phe amide bond, demonstrating no activity towards cathepsins B, H, or L. This specificity renders it essential for routine assays and mechanistic studies focusing on cathepsins E and D[1].

Cathepsin B is a cysteine protease located within the subcellular endosomes and lysosomal compartments that mediates apoptosis and can be used in cancer research.

Cathepsin G(1-5), an antimicrobial peptide identified within the clostripain-digested cathepsin G mixture [1], exhibits bactericidal properties.

Cathepsin L-IN-4 is a cathepsin L inhibitor with IC50 in the nanomolar range [1].

Z-FY-CHO (Z-Phe-Tyr-CHO) is a selective histone L (Cat L) inhibitor that promotes autophagy, reduces the accumulation of P62, and blocks the activation of caspase-3 and PARP.

Acetyl-Calpastatin (184-210)(human) acetate is a potent, selective and reversible calpain inhibitor with Ki values of 0.2 nM and 6 μM for µ-calpain and cathepsin L, respectively.

Leupeptin is a competitive protease inhibitor produced by actinomycetes. Leupeptin can inhibit cysteine, serine and threonine peptidases. Leupeptin inhibits serine proteinases (trypsin (Ki=3.5 nM), plasmin (Ki= 3.4 nM), porcine kallikrein), and cysteine p

NFAT Inhibitor (VIVIT peptide) is a cell-permeable compound that selectively inhibits the calcineurin-mediated dephosphorylation of NFAT.

Gly-Phe β-naphthylamide acetate is the substrate of Cathepsin C and can be used for research on the function of cathepsin C, intralysosomal hydrolysis and lysosomal membrane permeability.

H-Arg-4MβNA (H-Arg-4MbNA) is a peptide that serves as a substrate for cathepsin H. The enzyme activity is often detected in gel electrophoresis.

(Rac)-Z-Phe-Phe-FMK (Cathepsin L-IN-2) is a cathepsin L inhibitor that inhibits the tendency of β-amyloid to induce apoptotic changes .

Acetyl-Calpastatin(184-210)(human) TFA, a potent, selective, and reversible calpain inhibitor, has Ki values of 0.2 nM for µ-calpain and 6 μM for cathepsin L, indicating high specificity and efficacy in enzyme inhibition [1] [2].

LL-37 scrambled peptide acetate, a scrambled version of the cathepsin antimicrobial peptide LL-37, is commonly used as a negative control in experiments involving the LL-37 peptide.

N-CBZ-Phe-Arg-AMC TFA (Z-FR-AMC TFA) is a fluorescent substrate for serine proteases, which releases free AMC upon protease cleavage. Its excitation/emission wavelengths are 380/460 nm, and it can be used to assess the activity of trypsin, plasmin, and cathepsin.

Ac-Leu-Val-Lys-Aldehyde is a potent inhibitor of cathepsin B, with an inhibitory concentration (IC50) of 4 nM. It significantly reduces quinolinic acid-induced cell death in the striatum and results in the accumulation of LC3-II [1].

H-Pro-Thr-Glu-Phe-p-nitro-Phe-Arg-Leu-OH is a water-soluble polypeptide that serves as a substrate for the enzymes cathepsin D, pepsin, and pepsinogen, with potential applications in biochemical analysis [1] [2].

Hepcidin-1 (mouse) TFA, an endogenous peptide hormone, regulates iron homeostasis by upregulating mRNA levels of TRAP, cathepsin K, and MMP-9, enhancing TRAP-5b protein secretion, and downregulating FPN1 protein levels, thereby increasing intracellular iron. It also promotes osteoclast differentiation [1].

Ac-PLVE-FMK (Ac-Pro-Leu-Val-Glu(OMe)-CH2F), a tetrapeptidyl fluoromethylketone (FMK), acts as a cathepsin inhibitor and is used in cancer research [1].

Ac-VLPE-FMK, a tetrapeptidyl mono-fluoromethyl ketone (m-FMK), inhibits Cathepsin B (Cat-B) and Cathepsin L (Cat-L) and is used in cancer aggressiveness research [1] [2].

Z-Phe-Phe-Diazomethylketone is a selective inhibitor of cathepsin L [1].

Hepcidin-1 (mouse) is a peptide hormone that regulates iron balance, elevates mRNA for TRAP, cathepsin K, and MMP-9, and promotes TRAP-5b protein secretion. This compound also reduces FPN1 protein levels and boosts intracellular iron, ultimately aiding in osteoclast differentiation [1].
