MMP-1 27.5 μM (Km) MMP-8 MMP-13 5.2 μM (Km) MMP-14 7.9 μM (Km)
A wide range of matrix metalloproteinases (MMPs), including MMP-1, -2, -7, -8, -9, -13, and -17. This peptide serves as an improved FRET substrate for these enzymes, with enhanced substrate properties compared to the standard Mca-PLGL-Dpa-AR-NH2 substrate. |

| ln Vitro |
Specificity for collagenase (MMP-1, MMP-8, MMP-13) and MT1-MMP (MMP-14): Mca-Lys-Pro-Leu-Gly-Leu-Dap(Dnp)-Ala-Arg-NH26 The constant (kcat/Km) is increased by 2–9 times, or 3 times, in comparison with FS-1 [1].
This compound is a highly sensitive FRET substrate for MMPs. It is cleaved by multiple MMP isoforms, including gelatinases (MMP-2, -9), collagenases (MMP-1, -8, -13), and matrilysin (MMP-7). The N-terminal elongation with a Lys residue improves its specificity constant (kcat/Km) and overall substrate properties, making it a superior tool for measuring MMP activity. |
| ln Vivo |
As a research substrate, Mca-Lys-Pro-Leu-Gly-Leu-Dap(Dnp)-Ala-Arg-NH2 has no in vivo activity of its own. However, it is widely used for ex vivo analyses. It can be used to measure MMP activity in tissue lysates or biological fluids from animal models of cancer, arthritis, fibrosis, and other diseases where MMPs are dysregulated.
|
| Enzyme Assay |
For non-cellular assays, the FRET substrate is diluted to the desired concentration (e.g., 5-20 uM) in an assay buffer (e.g., 50 mM Tris-HCl, pH 7.5, 10 mM CaCl2, 150 mM NaCl). The reaction is initiated by adding the MMP enzyme (1-10 nM). The increase in fluorescence is measured (excitation 325 nm, emission 393 nm) using a fluorescence plate reader. The initial reaction velocity (V0) is calculated from the linear portion of the curve.
|
| Cell Assay |
Mca-Lys-Pro-Leu-Gly-Leu-Dap(Dnp)-Ala-Arg-NH2 is not a drug, so it is not used in standard cell-based assays for toxicity or efficacy. Instead, cells are treated with test compounds (e.g., MMP inhibitors or activators). Then, the cells are lysed, and the cleared lysate is incubated with this FRET substrate to measure MMP activity. The fluorescence signal is normalized to total protein concentration determined by a BCA assay.
|
| Animal Protocol |
For ex vivo activity measurements, animals are treated with test compounds or disease models are induced. Tissues (e.g., tumor, synovium) or bodily fluids (e.g., plasma, synovial fluid) are collected and homogenized. The lysate is clarified by centrifugation. The protein concentration is quantified, and the cleared lysate is incubated with the FRET substrate. The resulting increase in fluorescence is measured to calculate MMP activity.
|
| ADME/Pharmacokinetics |
The compound itself is a peptide with a molecular weight of 1221.34 g/mol and is stored as a solid at -20degC, protected from light. The peptide is soluble in water and is typically reconstituted in DMSO to make a stable stock solution (e.g., 10 mM). Once in solution, it is stable for several hours, but long-term storage should be as a dry powder at -20degC.
|
| Toxicity/Toxicokinetics |
The Mca-Lys-Pro-Leu-Gly-Leu-Dap(Dnp)-Ala-Arg-NH2 peptide is not toxic at the concentrations used in standard activity assays (1-50 uM). However, standard laboratory safety precautions for handling research chemicals should be followed. Appropriate personal protective equipment (PPE), such as gloves and a lab coat, should be worn at all times.

| Additional Infomation |
This FRET substrate is a widely used research tool for studying MMP activity in drug discovery. It is also known by the synonym FS-6. It is often used in high-throughput screening (HTS) to discover new MMP inhibitors. It is an improved version of the classic MMP FRET substrate Mca-PLGL-Dpa-AR-NH2. Its structure and mechanism of action (FRET) make it a valuable tool for studying MMP biology.
